It's a port (or close to a port) of the library for ruby at http://github.com/mongodb/mongo-ruby-driver/. + +A simple example of inserting a document. + +```javascript + var MongoClient = require('mongodb').MongoClient + , format = require('util').format; + + MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { + if(err) throw err; + + var collection = db.collection('test_insert'); + collection.insert({a:2}, function(err, docs) { + + collection.count(function(err, count) { + console.log(format("count = %s", count)); + }); + + // Locate all the entries using find + collection.find().toArray(function(err, results) { + console.dir(results); + // Let's close the db + db.close(); + }); + }); + }) +``` + +## Data types + +To store and retrieve the non-JSON MongoDb primitives ([ObjectID](http://www.mongodb.org/display/DOCS/Object+IDs), Long, Binary, [Timestamp](http://www.mongodb.org/display/DOCS/Timestamp+data+type), [DBRef](http://www.mongodb.org/display/DOCS/Database+References#DatabaseReferences-DBRef), Code). + +In particular, every document has a unique `_id` which can be almost any type, and by default a 12-byte ObjectID is created. ObjectIDs can be represented as 24-digit hexadecimal strings, but you must convert the string back into an ObjectID before you can use it in the database. For example: + +```javascript + // Get the objectID type + var ObjectID = require('mongodb').ObjectID; + + var idString = '4e4e1638c85e808431000003'; + collection.findOne({_id: new ObjectID(idString)}, console.log) // ok + collection.findOne({_id: idString}, console.log) // wrong! callback gets undefined +``` + +Here are the constructors the non-Javascript BSON primitive types: + +```javascript + // Fetch the library + var mongo = require('mongodb'); + // Create new instances of BSON types + new mongo.Long(numberString) + new mongo.ObjectID(hexString) + new mongo.Timestamp() // the actual unique number is generated on insert. + new mongo.DBRef(collectionName, id, dbName) + new mongo.Binary(buffer) // takes a string or Buffer + new mongo.Code(code, [context]) + new mongo.Symbol(string) + new mongo.MinKey() + new mongo.MaxKey() + new mongo.Double(number) // Force double storage +``` + +### The C/C++ bson parser/serializer + +If you are running a version of this library has the C/C++ parser compiled, to enable the driver to use the C/C++ bson parser pass it the option native_parser:true like below + +```javascript + // using native_parser: + MongoClient.connect('mongodb://127.0.0.1:27017/test' + , {db: {native_parser: true}}, function(err, db) {}) +``` + +The C++ parser uses the js objects both for serialization and deserialization. + +## GitHub information + +The source code is available at http://github.com/mongodb/node-mongodb-native. +You can either clone the repository or download a tarball of the latest release. + +Once you have the source you can test the driver by running + + $ node test/runner.js -t functional + +in the main directory. You will need to have a mongo instance running on localhost for the integration tests to pass. + +## Examples + +For examples look in the examples/ directory. You can execute the examples using node. + + $ cd examples + $ node queries.js + +## GridStore + +The GridStore class allows for storage of binary files in mongoDB using the mongoDB defined files and chunks collection definition. + +For more information have a look at [Gridstore](https://github.com/mongodb/node-mongodb-native/blob/master/docs/gridfs.md) + +## Replicasets + +For more information about how to connect to a replicaset have a look at the extensive documentation [Documentation](http://mongodb.github.com/node-mongodb-native/) + +### Primary Key Factories + +Defining your own primary key factory allows you to generate your own series of id's +(this could f.ex be to use something like ISBN numbers). The generated the id needs to be a 12 byte long "string". + +Simple example below + +```javascript + var MongoClient = require('mongodb').MongoClient + , format = require('util').format; + + // Custom factory (need to provide a 12 byte array); + CustomPKFactory = function() {} + CustomPKFactory.prototype = new Object(); + CustomPKFactory.createPk = function() { + return new ObjectID("aaaaaaaaaaaa"); + } + + MongoClient.connect('mongodb://127.0.0.1:27017/test', {'pkFactory':CustomPKFactory}, function(err, db) { + if(err) throw err; + + db.dropDatabase(function(err, done) { + + db.createCollection('test_custom_key', function(err, collection) { + + collection.insert({'a':1}, function(err, docs) { + + collection.find({'_id':new ObjectID("aaaaaaaaaaaa")}).toArray(function(err, items) { + console.dir(items); + // Let's close the db + db.close(); + }); + }); + }); + }); + }); +``` + +## Documentation + +If this document doesn't answer your questions, see the source of +[Collection](https://github.com/mongodb/node-mongodb-native/blob/master/lib/mongodb/collection.js) +or [Cursor](https://github.com/mongodb/node-mongodb-native/blob/master/lib/mongodb/cursor.js), +or the documentation at MongoDB for query and update formats. + +### Find + +The find method is actually a factory method to create +Cursor objects. A Cursor lazily uses the connection the first time +you call `nextObject`, `each`, or `toArray`. + +The basic operation on a cursor is the `nextObject` method +that fetches the next matching document from the database. The convenience +methods `each` and `toArray` call `nextObject` until the cursor is exhausted. + +Signatures: + +```javascript + var cursor = collection.find(query, [fields], options); + cursor.sort(fields).limit(n).skip(m). + + cursor.nextObject(function(err, doc) {}); + cursor.each(function(err, doc) {}); + cursor.toArray(function(err, docs) {}); + + cursor.rewind() // reset the cursor to its initial state. +``` + +Useful chainable methods of cursor. These can optionally be options of `find` instead of method calls: + + * `.limit(n).skip(m)` to control paging. + * `.sort(fields)` Order by the given fields. There are several equivalent syntaxes: + * `.sort({field1: -1, field2: 1})` descending by field1, then ascending by field2. + * `.sort([['field1', 'desc'], ['field2', 'asc']])` same as above + * `.sort([['field1', 'desc'], 'field2'])` same as above + * `.sort('field1')` ascending by field1 + +Other options of `find`: + +* `fields` the fields to fetch (to avoid transferring the entire document) +* `tailable` if true, makes the cursor [tailable](http://www.mongodb.org/display/DOCS/Tailable+Cursors). +* `batchSize` The number of the subset of results to request the database +to return for every request. This should initially be greater than 1 otherwise +the database will automatically close the cursor. The batch size can be set to 1 +with `batchSize(n, function(err){})` after performing the initial query to the database. +* `hint` See [Optimization: hint](http://www.mongodb.org/display/DOCS/Optimization#Optimization-Hint). +* `explain` turns this into an explain query. You can also call +`explain()` on any cursor to fetch the explanation. +* `snapshot` prevents documents that are updated while the query is active +from being returned multiple times. See more +[details about query snapshots](http://www.mongodb.org/display/DOCS/How+to+do+Snapshotted+Queries+in+the+Mongo+Database). +* `timeout` if false, asks MongoDb not to time out this cursor after an +inactivity period. + +For information on how to create queries, see the +[MongoDB section on querying](http://www.mongodb.org/display/DOCS/Querying). + +```javascript + var MongoClient = require('mongodb').MongoClient + , format = require('util').format; + + MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { + if(err) throw err; + + var collection = db + .collection('test') + .find({}) + .limit(10) + .toArray(function(err, docs) { + console.dir(docs); + }); + }); +``` + +### Insert + +Signature: + +```javascript + collection.insert(docs, options, [callback]); +``` + +where `docs` can be a single document or an array of documents. + +Useful options: + +* `w:1` Should always set if you have a callback. + +See also: [MongoDB docs for insert](http://www.mongodb.org/display/DOCS/Inserting). + +```javascript + var MongoClient = require('mongodb').MongoClient + , format = require('util').format; + + MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { + if(err) throw err; + + db.collection('test').insert({hello: 'world'}, {w:1}, function(err, objects) { + if (err) console.warn(err.message); + if (err && err.message.indexOf('E11000 ') !== -1) { + // this _id was already inserted in the database + } + }); + }); +``` + +Note that there's no reason to pass a callback to the insert or update commands +unless you use the `w:1` option. If you don't specify `w:1`, then +your callback will be called immediately. + +### Update: update and insert (upsert) + +The update operation will update the first document that matches your query +(or all documents that match if you use `multi:true`). +If `w:1`, `upsert` is not set, and no documents match, your callback will return 0 documents updated. + +See the [MongoDB docs](http://www.mongodb.org/display/DOCS/Updating) for +the modifier (`$inc`, `$set`, `$push`, etc.) formats. + +Signature: + +```javascript + collection.update(criteria, objNew, options, [callback]); +``` + +Useful options: + +* `w:1` Should always set if you have a callback. +* `multi:true` If set, all matching documents are updated, not just the first. +* `upsert:true` Atomically inserts the document if no documents matched. + +Example for `update`: + +```javascript + var MongoClient = require('mongodb').MongoClient + , format = require('util').format; + + MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { + if(err) throw err; + + db.collection('test').update({hi: 'here'}, {$set: {hi: 'there'}}, {w:1}, function(err) { + if (err) console.warn(err.message); + else console.log('successfully updated'); + }); + }); +``` + +### Find and modify + +`findAndModify` is like `update`, but it also gives the updated document to +your callback. But there are a few key differences between findAndModify and +update: + + 1. The signatures differ. + 2. You can only findAndModify a single item, not multiple items. + +Signature: + +```javascript + collection.findAndModify(query, sort, update, options, callback) +``` + +The sort parameter is used to specify which object to operate on, if more than +one document matches. It takes the same format as the cursor sort (see +Connection.find above). + +See the +[MongoDB docs for findAndModify](http://www.mongodb.org/display/DOCS/findAndModify+Command) +for more details. + +Useful options: + +* `remove:true` set to a true to remove the object before returning +* `new:true` set to true if you want to return the modified object rather than the original. Ignored for remove. +* `upsert:true` Atomically inserts the document if no documents matched. + +Example for `findAndModify`: + +```javascript + var MongoClient = require('mongodb').MongoClient + , format = require('util').format; + + MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { + if(err) throw err; + db.collection('test').findAndModify({hello: 'world'}, [['_id','asc']], {$set: {hi: 'there'}}, {}, function(err, object) { + if (err) console.warn(err.message); + else console.dir(object); // undefined if no matching object exists. + }); + }); +``` + +### Save + +The `save` method is a shorthand for upsert if the document contains an +`_id`, or an insert if there is no `_id`. + +## Release Notes + +See HISTORY + +## Credits + +1.

These classes manage the underlying memory for you in a safer way than just handing off an allocated array. You should now `*NanAsciiString(handle)` to access the raw `char` data, you can also allocate on the heap if you need to keep a reference. +* Two more NanMakeCallback overloads have been added to for parity with Node core. +* You can now `NanNew(std::string)` (use `NanNew(std::string&)` to pass by reference) +* NanSetTemplate, NanSetPrototypeTemplate and NanSetInstanceTemplate have been added. + +### May-2014: 1.1.0 release + +* We've deprecated `NanSymbol()`, you should just use `NanNew()` now. +* `NanNull()`, `NanUndefined()`, `NanTrue()`, `NanFalse()` all return `Local`s now. +* `nan_isolate` is gone, it was intended to be internal-only but if you were using it then you should switch to `v8::Isolate::GetCurrent()`. +* `NanNew()` has received some additional overload-love so you should be able to give it many kinds of values without specifying the ``. +* Lots of small fixes and additions to expand the V8 API coverage, *use the source, Luke*. + + +### May-2014: Major changes for V8 3.25 / Node 0.11.13 + +Node 0.11.11 and 0.11.12 were both broken releases for native add-ons, you simply can't properly compile against either of them for different reasons. But we now have a 0.11.13 release that jumps a couple of versions of V8 ahead and includes some more, major (traumatic) API changes. + +Because we are now nearing Node 0.12 and estimate that the version of V8 we are using in Node 0.11.13 will be close to the API we get for 0.12, we have taken the opportunity to not only *fix* NAN for 0.11.13 but make some major changes to improve the NAN API. + +We have **removed support for Node 0.11 versions prior to 0.11.13**. As usual, our tests are run against (and pass) the last 5 versions of Node 0.8 and Node 0.10. We also include Node 0.11.13 obviously. + +The major change is something that [Benjamin Byholm](kkoopa) has put many hours in to. We now have a fantastic new `NanNew(args)` interface for creating new `Local`s, this replaces `NanNewLocal()` and much more. If you look in [./nan.h](nan.h) you'll see a large number of overloaded versions of this method. In general you should be able to `NanNew(arguments)` for any type you want to make a `Local` from. This includes `Persistent` types, so we now have a `Local NanNew(const Persistent arg)` to replace `NanPersistentToLocal()`. + +We also now have `NanUndefined()`, `NanNull()`, `NanTrue()` and `NanFalse()`. Mainly because of the new requirement for an `Isolate` argument for each of the native V8 versions of this. + +V8 has now introduced an `EscapableHandleScope` from which you `scope.Escape(Local value)` to *return* a value from a one scope to another. This replaces the standard `HandleScope` and `scope.Close(Local value)`, although `HandleScope` still exists for when you don't need to return a handle to the caller. For NAN we are exposing it as `NanEscapableScope()` and `NanEscapeScope()`, while `NanScope()` is still how you create a new scope that doesn't need to return handles. For older versions of Node/V8, it'll still map to the older `HandleScope` functionality. + +`NanFromV8String()` was deprecated and has now been removed. You should use `NanCString()` or `NanRawString()` instead. + +Because `node::MakeCallback()` now takes an `Isolate`, and because it doesn't exist in older versions of Node, we've introduced `NanMakeCallback()`. You should *always* use this when calling a JavaScript function from C++. + +There's lots more, check out the Changelog in nan.h or look through [#86](https://github.com/rvagg/nan/pull/86) for all the gory details. + +### Dec-2013: NanCString and NanRawString + +Two new functions have been introduced to replace the functionality that's been provided by `NanFromV8String` until now. NanCString has sensible defaults so it's super easy to fetch a null-terminated c-style string out of a `v8::String`. `NanFromV8String` is still around and has defaults that allow you to pass a single handle to fetch a `char*` while `NanRawString` requires a little more attention to arguments. + +### Nov-2013: Node 0.11.9+ breaking V8 change + +The version of V8 that's shipping with Node 0.11.9+ has changed the signature for new `Local`s to: `v8::Local::New(isolate, value)`, i.e. introducing the `isolate` argument and therefore breaking all new `Local` declarations for previous versions. NAN 0.6+ now includes a `NanNewLocal(value)` that can be used in place to work around this incompatibility and maintain compatibility with 0.8->0.11.9+ (minus a few early 0.11 releases). + +For example, if you wanted to return a `null` on a callback you will have to change the argument from `v8::Local::New(v8::Null())` to `NanNewLocal(v8::Null())`. + +### Nov-2013: Change to binding.gyp `"include_dirs"` for NAN + +Inclusion of NAN in a project's binding.gyp is now greatly simplified. You can now just use `" +## Usage + +Simply add **NAN** as a dependency in the *package.json* of your Node addon: + +``` bash +$ npm install --save nan +``` + +Pull in the path to **NAN** in your *binding.gyp* so that you can use `#include ` in your *.cpp* files: + +``` python +"include_dirs" : [ + "` when compiling your addon. + + +## Example + +See **[LevelDOWN](https://github.com/rvagg/node-leveldown/pull/48)** for a full example of **NAN** in use. + +For a simpler example, see the **[async pi estimation example](https://github.com/rvagg/nan/tree/master/examples/async_pi_estimate)** in the examples directory for full code and an explanation of what this Monte Carlo Pi estimation example does.

You can check if a `NanCallback` is empty with the `bool IsEmpty()` method. Additionally a generic constructor is available for using +`NanCallback` without performing heap allocations. + + +### NanAsyncWorker + +`NanAsyncWorker` is an abstract class that you can subclass to have much of the annoying async queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the async work is in progress. + +See a rough outline of the implementation: + +```c++ +class NanAsyncWorker { +public: + NanAsyncWorker (NanCallback *callback); + + // Clean up persistent handles and delete the *callback + virtual ~NanAsyncWorker (); + + // Check the `ErrorMessage()` and call HandleOKCallback() + // or HandleErrorCallback depending on whether it has been set or not + virtual void WorkComplete (); + + // You must implement this to do some async work. If there is an + // error then use `SetErrorMessage()` to set an error message and the callback will + // be passed that string in an Error object + virtual void Execute (); + + // Save a V8 object in a Persistent handle to protect it from GC + void SaveToPersistent(const char *key, Local &obj); + + // Fetch a stored V8 object (don't call from within `Execute()`) + Local GetFromPersistent(const char *key); + + // Get the error message (or NULL) + const char *ErrorMessage(); + + // Set an error message + void SetErrorMessage(const char *msg); + +protected: + // Default implementation calls the callback function with no arguments. + // Override this to return meaningful data + virtual void HandleOKCallback (); + + // Default implementation calls the callback function with an Error object + // wrapping the `errmsg` string + virtual void HandleErrorCallback (); +}; +``` + + +### NanAsyncQueueWorker(NanAsyncWorker *) + +`NanAsyncQueueWorker` will run a `NanAsyncWorker` asynchronously via libuv. Both the *execute* and *after_work* steps are taken care of for you—most of the logic for this is embedded in `NanAsyncWorker`. + +### Contributors + +NAN is only possible due to the excellent work of the following contributors: + + + + + + + + +

These classes manage the underlying memory for you in a safer way than just handing off an allocated array. You should now `*NanAsciiString(handle)` to access the raw `char` data, you can also allocate on the heap if you need to keep a reference. +* Two more NanMakeCallback overloads have been added to for parity with Node core. +* You can now `NanNew(std::string)` (use `NanNew(std::string&)` to pass by reference) +* NanSetTemplate, NanSetPrototypeTemplate and NanSetInstanceTemplate have been added. + +### May-2014: 1.1.0 release + +* We've deprecated `NanSymbol()`, you should just use `NanNew()` now. +* `NanNull()`, `NanUndefined()`, `NanTrue()`, `NanFalse()` all return `Local`s now. +* `nan_isolate` is gone, it was intended to be internal-only but if you were using it then you should switch to `v8::Isolate::GetCurrent()`. +* `NanNew()` has received some additional overload-love so you should be able to give it many kinds of values without specifying the ``. +* Lots of small fixes and additions to expand the V8 API coverage, *use the source, Luke*. + + +### May-2014: Major changes for V8 3.25 / Node 0.11.13 + +Node 0.11.11 and 0.11.12 were both broken releases for native add-ons, you simply can't properly compile against either of them for different reasons. But we now have a 0.11.13 release that jumps a couple of versions of V8 ahead and includes some more, major (traumatic) API changes. + +Because we are now nearing Node 0.12 and estimate that the version of V8 we are using in Node 0.11.13 will be close to the API we get for 0.12, we have taken the opportunity to not only *fix* NAN for 0.11.13 but make some major changes to improve the NAN API. + +We have **removed support for Node 0.11 versions prior to 0.11.13**. As usual, our tests are run against (and pass) the last 5 versions of Node 0.8 and Node 0.10. We also include Node 0.11.13 obviously. + +The major change is something that [Benjamin Byholm](kkoopa) has put many hours in to. We now have a fantastic new `NanNew(args)` interface for creating new `Local`s, this replaces `NanNewLocal()` and much more. If you look in [./nan.h](nan.h) you'll see a large number of overloaded versions of this method. In general you should be able to `NanNew(arguments)` for any type you want to make a `Local` from. This includes `Persistent` types, so we now have a `Local NanNew(const Persistent arg)` to replace `NanPersistentToLocal()`. + +We also now have `NanUndefined()`, `NanNull()`, `NanTrue()` and `NanFalse()`. Mainly because of the new requirement for an `Isolate` argument for each of the native V8 versions of this. + +V8 has now introduced an `EscapableHandleScope` from which you `scope.Escape(Local value)` to *return* a value from a one scope to another. This replaces the standard `HandleScope` and `scope.Close(Local value)`, although `HandleScope` still exists for when you don't need to return a handle to the caller. For NAN we are exposing it as `NanEscapableScope()` and `NanEscapeScope()`, while `NanScope()` is still how you create a new scope that doesn't need to return handles. For older versions of Node/V8, it'll still map to the older `HandleScope` functionality. + +`NanFromV8String()` was deprecated and has now been removed. You should use `NanCString()` or `NanRawString()` instead. + +Because `node::MakeCallback()` now takes an `Isolate`, and because it doesn't exist in older versions of Node, we've introduced `NanMakeCallback()`. You should *always* use this when calling a JavaScript function from C++. + +There's lots more, check out the Changelog in nan.h or look through [#86](https://github.com/rvagg/nan/pull/86) for all the gory details. + +### Dec-2013: NanCString and NanRawString + +Two new functions have been introduced to replace the functionality that's been provided by `NanFromV8String` until now. NanCString has sensible defaults so it's super easy to fetch a null-terminated c-style string out of a `v8::String`. `NanFromV8String` is still around and has defaults that allow you to pass a single handle to fetch a `char*` while `NanRawString` requires a little more attention to arguments. + +### Nov-2013: Node 0.11.9+ breaking V8 change + +The version of V8 that's shipping with Node 0.11.9+ has changed the signature for new `Local`s to: `v8::Local::New(isolate, value)`, i.e. introducing the `isolate` argument and therefore breaking all new `Local` declarations for previous versions. NAN 0.6+ now includes a `NanNewLocal(value)` that can be used in place to work around this incompatibility and maintain compatibility with 0.8->0.11.9+ (minus a few early 0.11 releases). + +For example, if you wanted to return a `null` on a callback you will have to change the argument from `v8::Local::New(v8::Null())` to `NanNewLocal(v8::Null())`. + +### Nov-2013: Change to binding.gyp `"include_dirs"` for NAN + +Inclusion of NAN in a project's binding.gyp is now greatly simplified.

The final argument allows setting `String::WriteOptions`. +Just remember that you'll end up with an object that you'll need to `delete[]` at some point unless you supply your own buffer: + +```c++ +size_t count; +void* decoded = NanRawString(args[1], Nan::BASE64, &count, NULL, 0, String::HINT_MANY_WRITES_EXPECTED); +... +delete[] reinterpret_cast(decoded); +``` + + +### char* NanCString(Handle<Value>, size_t *[, char *, size_t, int]) + +Deprecated. Use `NanUtf8String` instead. + +When you want to convert a V8 `String` to a null-terminated C `char*` use `NanCString`. The resulting `char*` will be UTF-8-encoded, and you need to supply a pointer to a variable that will be assigned the number of bytes in the returned string. It is also possible to supply a buffer and its length to the function in order not to have a new buffer allocated. The final argument allows optionally setting `String::WriteOptions`, which default to `v8::String::NO_OPTIONS`. +Just remember that you'll end up with an object that you'll need to `delete[]` at some point unless you supply your own buffer: + +```c++ +size_t count; +char* name = NanCString(args[0], &count); +... +delete[] name; +``` + + +### NanAsciiString + +Convert a `String` to zero-terminated, Ascii-encoded `char *`. + +```c++ +NAN_METHOD(foo) { + NanScope(); + NanReturnValue(NanNew(*NanAsciiString(arg[0]))); +} +``` + + +### NanUtf8String + +Convert a `String` to zero-terminated, Utf8-encoded `char *`. + +```c++ +NAN_METHOD(foo) { + NanScope(); + NanReturnValue(NanNew(*NanUtf8String(arg[0]))); +} +``` + + +### NanUcs2String + +Convert a `String` to zero-terminated, Ucs2-encoded `uint16_t *`. + +```c++ +NAN_METHOD(foo) { + NanScope(); + NanReturnValue(NanNew(*NanUcs2String(arg[0]))); +} +``` + + +### bool NanBooleanOptionValue(Handle<Value>, Handle<String>[, bool]) + +When you have an "options" object that you need to fetch properties from, boolean options can be fetched with this pair. They check first if the object exists (`IsEmpty`), then if the object has the given property (`Has`) then they get and convert/coerce the property to a `bool`. + +The optional last parameter is the *default* value, which is `false` if left off: + +```c++ +// `foo` is false unless the user supplies a truthy value for it +bool foo = NanBooleanOptionValue(optionsObj, NanNew("foo")); +// `bar` is true unless the user supplies a falsy value for it +bool bar = NanBooleanOptionValueDefTrue(optionsObj, NanNew("bar"), true); +``` + + +### uint32_t NanUInt32OptionValue(Handle<Value>, Handle<String>, uint32_t) + +Similar to `NanBooleanOptionValue`, use `NanUInt32OptionValue` to fetch an integer option from your options object.

If used with the error code argument, it will add the supplied error code to the error object as a property called `code`. + + +### Local<Object> NanNewBufferHandle(char *, uint32_t), Local<Object> NanNewBufferHandle(uint32_t) + +The `Buffer` API has changed a little in Node 0.11, this helper provides consistent access to `Buffer` creation: + +```c++ +NanNewBufferHandle((char*)value.data(), value.size()); +``` + +Can also be used to initialize a `Buffer` with just a `size` argument. + +Can also be supplied with a `NanFreeCallback` and a hint for the garbage collector. + + +### Local<Object> NanBufferUse(char*, uint32_t) + +`Buffer::New(char*, uint32_t)` prior to 0.11 would make a copy of the data. +While it was possible to get around this, it required a shim by passing a +callback. So the new API `Buffer::Use(char*, uint32_t)` was introduced to remove +needing to use this shim. + +`NanBufferUse` uses the `char*` passed as the backing data, and will free the +memory automatically when the weak callback is called. Keep this in mind, as +careless use can lead to "double free or corruption" and other cryptic failures. + + +### bool NanHasInstance(Persistent<FunctionTemplate>&, Handle<Value>) + +Can be used to check the type of an object to determine it is of a particular class you have already defined and have a `Persistent` handle for. + + +### Local<Context> NanNewContextHandle([ExtensionConfiguration*, Handle<ObjectTemplate>, Handle<Value>]) +Creates a new `Local` handle. + +```c++ +Local ftmpl = NanNew(); +Local otmpl = ftmpl->InstanceTemplate(); +Local ctx = NanNewContextHandle(NULL, otmpl); +``` + + +### Local<Context> NanGetCurrentContext() + +Gets the current context. + +```c++ +Local ctx = NanGetCurrentContext(); +``` + + +### void NanDisposePersistent(Persistent<T> &) + +Use `NanDisposePersistent` to dispose a `Persistent` handle. + +```c++ +NanDisposePersistent(persistentHandle); +``` + + +### NanAssignPersistent(handle, object) + +Use `NanAssignPersistent` to assign a non-`Persistent` handle to a `Persistent` one. You can no longer just declare a `Persistent` handle and assign directly to it later, you have to `Reset` it in Node 0.11, so this makes it easier. + +In general it is now better to place anything you want to protect from V8's garbage collector as properties of a generic `Object` and then assign that to a `Persistent`. This works in older versions of Node also if you use `NanAssignPersistent`: + +```c++ +Persistent persistentHandle; + +... + +Local obj = NanNew(); +obj->Set(NanNew("key"), keyHandle); // where keyHandle might be a Local +NanAssignPersistent(persistentHandle, obj) +``` + + +### _NanWeakCallbackInfo<T, P>* NanMakeWeakPersistent(Handle<T>, P*, _NanWeakCallbackInfo<T, P>::Callback) + +Creates a weak persistent handle with the supplied parameter and `NAN_WEAK_CALLBACK`. + +```c++ +NAN_WEAK_CALLBACK(weakCallback) { + +... + +} + +Local func; + +... + +int *parameter = new int(0); +NanMakeWeakPersistent(func, parameter, &weakCallback); +``` + + +### NanSetTemplate(templ, name, value [, attributes]) + +Use to add properties on object and function templates. + + +### NanSetPrototypeTemplate(templ, name, value [, attributes]) + +Use to add prototype properties on function templates. + + +### NanSetInstanceTemplate(templ, name, value [, attributes]) + +Use to add instance properties on function templates. + + +### NanMakeCallback(target, func, argc, argv) + +Use instead of `node::MakeCallback` to call javascript functions.

You can check if a `NanCallback` is empty with the `bool IsEmpty()` method. Additionally a generic constructor is available for using +`NanCallback` without performing heap allocations. + + +### NanAsyncWorker + +`NanAsyncWorker` is an abstract class that you can subclass to have much of the annoying async queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the async work is in progress. + +See a rough outline of the implementation: + +```c++ +class NanAsyncWorker { +public: + NanAsyncWorker (NanCallback *callback); + + // Clean up persistent handles and delete the *callback + virtual ~NanAsyncWorker (); + + // Check the `ErrorMessage()` and call HandleOKCallback() + // or HandleErrorCallback depending on whether it has been set or not + virtual void WorkComplete (); + + // You must implement this to do some async work. If there is an + // error then use `SetErrorMessage()` to set an error message and the callback will + // be passed that string in an Error object + virtual void Execute (); + + // Save a V8 object in a Persistent handle to protect it from GC + void SaveToPersistent(const char *key, Local &obj); + + // Fetch a stored V8 object (don't call from within `Execute()`) + Local GetFromPersistent(const char *key); + + // Get the error message (or NULL) + const char *ErrorMessage(); + + // Set an error message + void SetErrorMessage(const char *msg); + +protected: + // Default implementation calls the callback function with no arguments. + // Override this to return meaningful data + virtual void HandleOKCallback (); + + // Default implementation calls the callback function with an Error object + // wrapping the `errmsg` string + virtual void HandleErrorCallback (); +}; +``` + + +### NanAsyncQueueWorker(NanAsyncWorker *) + +`NanAsyncQueueWorker` will run a `NanAsyncWorker` asynchronously via libuv. Both the *execute* and *after_work* steps are taken care of for you—most of the logic for this is embedded in `NanAsyncWorker`. + +### Contributors + +NAN is only possible due to the excellent work of the following contributors: + + + + + + + + +

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. + +module.exports = Transform; + +var Duplex = require('./_stream_duplex'); + +/**/ +var util = require('core-util-is'); +util.inherits = require('inherits'); +/**/ + +util.inherits(Transform, Duplex); + + +function TransformState(options, stream) { + this.afterTransform = function(er, data) { + return afterTransform(stream, er, data); + }; + + this.needTransform = false; + this.transforming = false; + this.writecb = null; + this.writechunk = null; +} + +function afterTransform(stream, er, data) { + var ts = stream._transformState; + ts.transforming = false; + + var cb = ts.writecb; + + if (!cb) + return stream.emit('error', new Error('no writecb in Transform class')); + + ts.writechunk = null; + ts.writecb = null; + + if (data !== null && data !== undefined) + stream.push(data); + + if (cb) + cb(er); + + var rs = stream._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + stream._read(rs.highWaterMark); + } +} + + +function Transform(options) { + if (!(this instanceof Transform)) + return new Transform(options); + + Duplex.call(this, options); + + var ts = this._transformState = new TransformState(options, this); + + // when the writable side finishes, then flush out anything remaining. + var stream = this; + + // start out asking for a readable event once data is transformed. + this._readableState.needReadable = true; + + // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. + this._readableState.sync = false; + + this.once('finish', function() { + if ('function' === typeof this._flush) + this._flush(function(er) { + done(stream, er); + }); + else + done(stream); + }); +} + +Transform.prototype.push = function(chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); +}; + +// This is the part where you do stuff! +// override this function in implementation classes. +// 'chunk' is an input chunk. +// +// Call `push(newChunk)` to pass along transformed output +// to the readable side.

It's a port (or close to a port) of the library for ruby at http://github.com/mongodb/mongo-ruby-driver/. - -A simple example of inserting a document. - -```javascript - var MongoClient = require('mongodb').MongoClient - , format = require('util').format; - - MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { - if(err) throw err; - - var collection = db.collection('test_insert'); - collection.insert({a:2}, function(err, docs) { - - collection.count(function(err, count) { - console.log(format("count = %s", count)); - }); - - // Locate all the entries using find - collection.find().toArray(function(err, results) { - console.dir(results); - // Let's close the db - db.close(); - }); - }); - }) -``` - -## Data types - -To store and retrieve the non-JSON MongoDb primitives ([ObjectID](http://www.mongodb.org/display/DOCS/Object+IDs), Long, Binary, [Timestamp](http://www.mongodb.org/display/DOCS/Timestamp+data+type), [DBRef](http://www.mongodb.org/display/DOCS/Database+References#DatabaseReferences-DBRef), Code). - -In particular, every document has a unique `_id` which can be almost any type, and by default a 12-byte ObjectID is created. ObjectIDs can be represented as 24-digit hexadecimal strings, but you must convert the string back into an ObjectID before you can use it in the database. For example: - -```javascript - // Get the objectID type - var ObjectID = require('mongodb').ObjectID; - - var idString = '4e4e1638c85e808431000003'; - collection.findOne({_id: new ObjectID(idString)}, console.log) // ok - collection.findOne({_id: idString}, console.log) // wrong! callback gets undefined -``` - -Here are the constructors the non-Javascript BSON primitive types: - -```javascript - // Fetch the library - var mongo = require('mongodb'); - // Create new instances of BSON types - new mongo.Long(numberString) - new mongo.ObjectID(hexString) - new mongo.Timestamp() // the actual unique number is generated on insert. - new mongo.DBRef(collectionName, id, dbName) - new mongo.Binary(buffer) // takes a string or Buffer - new mongo.Code(code, [context]) - new mongo.Symbol(string) - new mongo.MinKey() - new mongo.MaxKey() - new mongo.Double(number) // Force double storage -``` - -### The C/C++ bson parser/serializer - -If you are running a version of this library has the C/C++ parser compiled, to enable the driver to use the C/C++ bson parser pass it the option native_parser:true like below - -```javascript - // using native_parser: - MongoClient.connect('mongodb://127.0.0.1:27017/test' - , {db: {native_parser: true}}, function(err, db) {}) -``` - -The C++ parser uses the js objects both for serialization and deserialization. - -## GitHub information - -The source code is available at http://github.com/mongodb/node-mongodb-native. -You can either clone the repository or download a tarball of the latest release. - -Once you have the source you can test the driver by running - - $ node test/runner.js -t functional - -in the main directory. You will need to have a mongo instance running on localhost for the integration tests to pass. - -## Examples - -For examples look in the examples/ directory. You can execute the examples using node. - - $ cd examples - $ node queries.js - -## GridStore - -The GridStore class allows for storage of binary files in mongoDB using the mongoDB defined files and chunks collection definition. - -For more information have a look at [Gridstore](https://github.com/mongodb/node-mongodb-native/blob/master/docs/gridfs.md) - -## Replicasets - -For more information about how to connect to a replicaset have a look at the extensive documentation [Documentation](http://mongodb.github.com/node-mongodb-native/) - -### Primary Key Factories - -Defining your own primary key factory allows you to generate your own series of id's -(this could f.ex be to use something like ISBN numbers). The generated the id needs to be a 12 byte long "string". - -Simple example below - -```javascript - var MongoClient = require('mongodb').MongoClient - , format = require('util').format; - - // Custom factory (need to provide a 12 byte array); - CustomPKFactory = function() {} - CustomPKFactory.prototype = new Object(); - CustomPKFactory.createPk = function() { - return new ObjectID("aaaaaaaaaaaa"); - } - - MongoClient.connect('mongodb://127.0.0.1:27017/test', {'pkFactory':CustomPKFactory}, function(err, db) { - if(err) throw err; - - db.dropDatabase(function(err, done) { - - db.createCollection('test_custom_key', function(err, collection) { - - collection.insert({'a':1}, function(err, docs) { - - collection.find({'_id':new ObjectID("aaaaaaaaaaaa")}).toArray(function(err, items) { - console.dir(items); - // Let's close the db - db.close(); - }); - }); - }); - }); - }); -``` - -## Documentation - -If this document doesn't answer your questions, see the source of -[Collection](https://github.com/mongodb/node-mongodb-native/blob/master/lib/mongodb/collection.js) -or [Cursor](https://github.com/mongodb/node-mongodb-native/blob/master/lib/mongodb/cursor.js), -or the documentation at MongoDB for query and update formats. - -### Find - -The find method is actually a factory method to create -Cursor objects. A Cursor lazily uses the connection the first time -you call `nextObject`, `each`, or `toArray`. - -The basic operation on a cursor is the `nextObject` method -that fetches the next matching document from the database. The convenience -methods `each` and `toArray` call `nextObject` until the cursor is exhausted. - -Signatures: - -```javascript - var cursor = collection.find(query, [fields], options); - cursor.sort(fields).limit(n).skip(m). - - cursor.nextObject(function(err, doc) {}); - cursor.each(function(err, doc) {}); - cursor.toArray(function(err, docs) {}); - - cursor.rewind() // reset the cursor to its initial state. -``` - -Useful chainable methods of cursor. These can optionally be options of `find` instead of method calls: - - * `.limit(n).skip(m)` to control paging. - * `.sort(fields)` Order by the given fields. There are several equivalent syntaxes: - * `.sort({field1: -1, field2: 1})` descending by field1, then ascending by field2. - * `.sort([['field1', 'desc'], ['field2', 'asc']])` same as above - * `.sort([['field1', 'desc'], 'field2'])` same as above - * `.sort('field1')` ascending by field1 - -Other options of `find`: - -* `fields` the fields to fetch (to avoid transferring the entire document) -* `tailable` if true, makes the cursor [tailable](http://www.mongodb.org/display/DOCS/Tailable+Cursors). -* `batchSize` The number of the subset of results to request the database -to return for every request. This should initially be greater than 1 otherwise -the database will automatically close the cursor. The batch size can be set to 1 -with `batchSize(n, function(err){})` after performing the initial query to the database. -* `hint` See [Optimization: hint](http://www.mongodb.org/display/DOCS/Optimization#Optimization-Hint). -* `explain` turns this into an explain query. You can also call -`explain()` on any cursor to fetch the explanation. -* `snapshot` prevents documents that are updated while the query is active -from being returned multiple times. See more -[details about query snapshots](http://www.mongodb.org/display/DOCS/How+to+do+Snapshotted+Queries+in+the+Mongo+Database). -* `timeout` if false, asks MongoDb not to time out this cursor after an -inactivity period. - -For information on how to create queries, see the -[MongoDB section on querying](http://www.mongodb.org/display/DOCS/Querying). - -```javascript - var MongoClient = require('mongodb').MongoClient - , format = require('util').format; - - MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { - if(err) throw err; - - var collection = db - .collection('test') - .find({}) - .limit(10) - .toArray(function(err, docs) { - console.dir(docs); - }); - }); -``` - -### Insert - -Signature: - -```javascript - collection.insert(docs, options, [callback]); -``` - -where `docs` can be a single document or an array of documents. - -Useful options: - -* `w:1` Should always set if you have a callback. - -See also: [MongoDB docs for insert](http://www.mongodb.org/display/DOCS/Inserting). - -```javascript - var MongoClient = require('mongodb').MongoClient - , format = require('util').format; - - MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { - if(err) throw err; - - db.collection('test').insert({hello: 'world'}, {w:1}, function(err, objects) { - if (err) console.warn(err.message); - if (err && err.message.indexOf('E11000 ') !== -1) { - // this _id was already inserted in the database - } - }); - }); -``` - -Note that there's no reason to pass a callback to the insert or update commands -unless you use the `w:1` option. If you don't specify `w:1`, then -your callback will be called immediately. - -### Update: update and insert (upsert) - -The update operation will update the first document that matches your query -(or all documents that match if you use `multi:true`). -If `w:1`, `upsert` is not set, and no documents match, your callback will return 0 documents updated. - -See the [MongoDB docs](http://www.mongodb.org/display/DOCS/Updating) for -the modifier (`$inc`, `$set`, `$push`, etc.) formats. - -Signature: - -```javascript - collection.update(criteria, objNew, options, [callback]); -``` - -Useful options: - -* `w:1` Should always set if you have a callback. -* `multi:true` If set, all matching documents are updated, not just the first. -* `upsert:true` Atomically inserts the document if no documents matched. - -Example for `update`: - -```javascript - var MongoClient = require('mongodb').MongoClient - , format = require('util').format; - - MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { - if(err) throw err; - - db.collection('test').update({hi: 'here'}, {$set: {hi: 'there'}}, {w:1}, function(err) { - if (err) console.warn(err.message); - else console.log('successfully updated'); - }); - }); -``` - -### Find and modify - -`findAndModify` is like `update`, but it also gives the updated document to -your callback. But there are a few key differences between findAndModify and -update: - - 1. The signatures differ. - 2. You can only findAndModify a single item, not multiple items. - -Signature: - -```javascript - collection.findAndModify(query, sort, update, options, callback) -``` - -The sort parameter is used to specify which object to operate on, if more than -one document matches. It takes the same format as the cursor sort (see -Connection.find above). - -See the -[MongoDB docs for findAndModify](http://www.mongodb.org/display/DOCS/findAndModify+Command) -for more details. - -Useful options: - -* `remove:true` set to a true to remove the object before returning -* `new:true` set to true if you want to return the modified object rather than the original. Ignored for remove. -* `upsert:true` Atomically inserts the document if no documents matched. - -Example for `findAndModify`: - -```javascript - var MongoClient = require('mongodb').MongoClient - , format = require('util').format; - - MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { - if(err) throw err; - db.collection('test').findAndModify({hello: 'world'}, [['_id','asc']], {$set: {hi: 'there'}}, {}, function(err, object) { - if (err) console.warn(err.message); - else console.dir(object); // undefined if no matching object exists. - }); - }); -``` - -### Save - -The `save` method is a shorthand for upsert if the document contains an -`_id`, or an insert if there is no `_id`. - -## Release Notes - -See HISTORY - -## Credits - -1.

These classes manage the underlying memory for you in a safer way than just handing off an allocated array. You should now `*NanAsciiString(handle)` to access the raw `char` data, you can also allocate on the heap if you need to keep a reference. -* Two more NanMakeCallback overloads have been added to for parity with Node core. -* You can now `NanNew(std::string)` (use `NanNew(std::string&)` to pass by reference) -* NanSetTemplate, NanSetPrototypeTemplate and NanSetInstanceTemplate have been added. - -### May-2014: 1.1.0 release - -* We've deprecated `NanSymbol()`, you should just use `NanNew()` now. -* `NanNull()`, `NanUndefined()`, `NanTrue()`, `NanFalse()` all return `Local`s now. -* `nan_isolate` is gone, it was intended to be internal-only but if you were using it then you should switch to `v8::Isolate::GetCurrent()`. -* `NanNew()` has received some additional overload-love so you should be able to give it many kinds of values without specifying the ``. -* Lots of small fixes and additions to expand the V8 API coverage, *use the source, Luke*. - - -### May-2014: Major changes for V8 3.25 / Node 0.11.13 - -Node 0.11.11 and 0.11.12 were both broken releases for native add-ons, you simply can't properly compile against either of them for different reasons. But we now have a 0.11.13 release that jumps a couple of versions of V8 ahead and includes some more, major (traumatic) API changes. - -Because we are now nearing Node 0.12 and estimate that the version of V8 we are using in Node 0.11.13 will be close to the API we get for 0.12, we have taken the opportunity to not only *fix* NAN for 0.11.13 but make some major changes to improve the NAN API. - -We have **removed support for Node 0.11 versions prior to 0.11.13**. As usual, our tests are run against (and pass) the last 5 versions of Node 0.8 and Node 0.10. We also include Node 0.11.13 obviously. - -The major change is something that [Benjamin Byholm](kkoopa) has put many hours in to. We now have a fantastic new `NanNew(args)` interface for creating new `Local`s, this replaces `NanNewLocal()` and much more. If you look in [./nan.h](nan.h) you'll see a large number of overloaded versions of this method. In general you should be able to `NanNew(arguments)` for any type you want to make a `Local` from. This includes `Persistent` types, so we now have a `Local NanNew(const Persistent arg)` to replace `NanPersistentToLocal()`. - -We also now have `NanUndefined()`, `NanNull()`, `NanTrue()` and `NanFalse()`. Mainly because of the new requirement for an `Isolate` argument for each of the native V8 versions of this. - -V8 has now introduced an `EscapableHandleScope` from which you `scope.Escape(Local value)` to *return* a value from a one scope to another. This replaces the standard `HandleScope` and `scope.Close(Local value)`, although `HandleScope` still exists for when you don't need to return a handle to the caller. For NAN we are exposing it as `NanEscapableScope()` and `NanEscapeScope()`, while `NanScope()` is still how you create a new scope that doesn't need to return handles. For older versions of Node/V8, it'll still map to the older `HandleScope` functionality. - -`NanFromV8String()` was deprecated and has now been removed. You should use `NanCString()` or `NanRawString()` instead. - -Because `node::MakeCallback()` now takes an `Isolate`, and because it doesn't exist in older versions of Node, we've introduced `NanMakeCallback()`. You should *always* use this when calling a JavaScript function from C++. - -There's lots more, check out the Changelog in nan.h or look through [#86](https://github.com/rvagg/nan/pull/86) for all the gory details. - -### Dec-2013: NanCString and NanRawString - -Two new functions have been introduced to replace the functionality that's been provided by `NanFromV8String` until now. NanCString has sensible defaults so it's super easy to fetch a null-terminated c-style string out of a `v8::String`. `NanFromV8String` is still around and has defaults that allow you to pass a single handle to fetch a `char*` while `NanRawString` requires a little more attention to arguments. - -### Nov-2013: Node 0.11.9+ breaking V8 change - -The version of V8 that's shipping with Node 0.11.9+ has changed the signature for new `Local`s to: `v8::Local::New(isolate, value)`, i.e. introducing the `isolate` argument and therefore breaking all new `Local` declarations for previous versions. NAN 0.6+ now includes a `NanNewLocal(value)` that can be used in place to work around this incompatibility and maintain compatibility with 0.8->0.11.9+ (minus a few early 0.11 releases). - -For example, if you wanted to return a `null` on a callback you will have to change the argument from `v8::Local::New(v8::Null())` to `NanNewLocal(v8::Null())`. - -### Nov-2013: Change to binding.gyp `"include_dirs"` for NAN - -Inclusion of NAN in a project's binding.gyp is now greatly simplified. You can now just use `" -## Usage - -Simply add **NAN** as a dependency in the *package.json* of your Node addon: - -``` bash -$ npm install --save nan -``` - -Pull in the path to **NAN** in your *binding.gyp* so that you can use `#include ` in your *.cpp* files: - -``` python -"include_dirs" : [ - "` when compiling your addon. - - -## Example - -See **[LevelDOWN](https://github.com/rvagg/node-leveldown/pull/48)** for a full example of **NAN** in use. - -For a simpler example, see the **[async pi estimation example](https://github.com/rvagg/nan/tree/master/examples/async_pi_estimate)** in the examples directory for full code and an explanation of what this Monte Carlo Pi estimation example does.

Corresponds to `HandleScope::Close` or `EscapableHandleScope::Escape`. - - -### NanLocker() - -The introduction of `isolate` references for many V8 calls in Node 0.11 makes `NanLocker()` necessary, use it in place of `Locker locker`: - -```c++ -NAN_METHOD(Foo::Bar) { - NanLocker(); - ... - NanUnlocker(); -} -``` - - -### NanUnlocker() - -The introduction of `isolate` references for many V8 calls in Node 0.11 makes `NanUnlocker()` necessary, use it in place of `Unlocker unlocker`: - -```c++ -NAN_METHOD(Foo::Bar) { - NanLocker(); - ... - NanUnlocker(); -} -``` - - -### void * NanGetInternalFieldPointer(Handle<Object>, int) - -Gets a pointer to the internal field with at `index` from a V8 `Object` handle. - -```c++ -Local obj; -... -NanGetInternalFieldPointer(obj, 0); -``` - -### void NanSetInternalFieldPointer(Handle<Object>, int, void *) - -Sets the value of the internal field at `index` on a V8 `Object` handle. - -```c++ -static Persistent dataWrapperCtor; -... -Local wrapper = NanNew(dataWrapperCtor)->NewInstance(); -NanSetInternalFieldPointer(wrapper, 0, this); -``` - - -### Local<Object> NanObjectWrapHandle(Object) - -When you want to fetch the V8 object handle from a native object you've wrapped with Node's `ObjectWrap`, you should use `NanObjectWrapHandle`: - -```c++ -NanObjectWrapHandle(iterator)->Get(NanNew("end")) -``` - - -### Local<String> NanSymbol(const char *) - -Deprecated. Use `NanNew` instead. -Use to create string symbol objects (i.e. `v8::String::NewSymbol(x)`), for getting and setting object properties, or names of objects. - -```c++ -bool foo = false; -if (obj->Has(NanNew("foo"))) - foo = optionsObj->Get(NanNew("foo"))->BooleanValue() -``` - - -### Type NanGetPointerSafe(Type *[, Type]) - -A helper for getting values from optional pointers. If the pointer is `NULL`, the function returns the optional default value, which defaults to `0`. Otherwise, the function returns the value the pointer points to. - -```c++ -char *plugh(uint32_t *optional) { - char res[] = "xyzzy"; - uint32_t param = NanGetPointerSafe(optional, 0x1337); - switch (param) { - ... - } - NanSetPointerSafe(optional, 0xDEADBEEF); -} -``` - - -### bool NanSetPointerSafe(Type *, Type) - -A helper for setting optional argument pointers. If the pointer is `NULL`, the function simply returns `false`. Otherwise, the value is assigned to the variable the pointer points to. - -```c++ -const char *plugh(size_t *outputsize) { - char res[] = "xyzzy"; - if !(NanSetPointerSafe(outputsize, strlen(res) + 1)) { - ... - } - - ... -} -``` - - -### void* NanRawString(Handle<Value>, enum Nan::Encoding, size_t *, void *, size_t, int) - -Deprecated. Use something else. - -When you want to convert a V8 `String` to a `char*` buffer, use `NanRawString`. You have to supply an encoding as well as a pointer to a variable that will be assigned the number of bytes in the returned string. It is also possible to supply a buffer and its length to the function in order not to have a new buffer allocated. The final argument allows setting `String::WriteOptions`. -Just remember that you'll end up with an object that you'll need to `delete[]` at some point unless you supply your own buffer: - -```c++ -size_t count; -void* decoded = NanRawString(args[1], Nan::BASE64, &count, NULL, 0, String::HINT_MANY_WRITES_EXPECTED); -... -delete[] reinterpret_cast(decoded); -``` - - -### char* NanCString(Handle<Value>, size_t *[, char *, size_t, int]) - -Deprecated. Use `NanUtf8String` instead. - -When you want to convert a V8 `String` to a null-terminated C `char*` use `NanCString`. The resulting `char*` will be UTF-8-encoded, and you need to supply a pointer to a variable that will be assigned the number of bytes in the returned string. It is also possible to supply a buffer and its length to the function in order not to have a new buffer allocated. The final argument allows optionally setting `String::WriteOptions`, which default to `v8::String::NO_OPTIONS`. -Just remember that you'll end up with an object that you'll need to `delete[]` at some point unless you supply your own buffer: - -```c++ -size_t count; -char* name = NanCString(args[0], &count); -... -delete[] name; -``` - - -### NanAsciiString - -Convert a `String` to zero-terminated, Ascii-encoded `char *`. - -```c++ -NAN_METHOD(foo) { - NanScope(); - NanReturnValue(NanNew(*NanAsciiString(arg[0]))); -} -``` - - -### NanUtf8String - -Convert a `String` to zero-terminated, Utf8-encoded `char *`. - -```c++ -NAN_METHOD(foo) { - NanScope(); - NanReturnValue(NanNew(*NanUtf8String(arg[0]))); -} -``` - - -### NanUcs2String - -Convert a `String` to zero-terminated, Ucs2-encoded `uint16_t *`. - -```c++ -NAN_METHOD(foo) { - NanScope(); - NanReturnValue(NanNew(*NanUcs2String(arg[0]))); -} -``` - - -### bool NanBooleanOptionValue(Handle<Value>, Handle<String>[, bool]) - -When you have an "options" object that you need to fetch properties from, boolean options can be fetched with this pair. They check first if the object exists (`IsEmpty`), then if the object has the given property (`Has`) then they get and convert/coerce the property to a `bool`. - -The optional last parameter is the *default* value, which is `false` if left off: - -```c++ -// `foo` is false unless the user supplies a truthy value for it -bool foo = NanBooleanOptionValue(optionsObj, NanNew("foo")); -// `bar` is true unless the user supplies a falsy value for it -bool bar = NanBooleanOptionValueDefTrue(optionsObj, NanNew("bar"), true); -``` - - -### uint32_t NanUInt32OptionValue(Handle<Value>, Handle<String>, uint32_t) - -Similar to `NanBooleanOptionValue`, use `NanUInt32OptionValue` to fetch an integer option from your options object. Can be any kind of JavaScript `Number` and it will be coerced to an unsigned 32-bit integer. - -Requires all 3 arguments as a default is not optional: - -```c++ -uint32_t count = NanUInt32OptionValue(optionsObj, NanNew("count"), 1024); -``` - - -### NanError(message), NanTypeError(message), NanRangeError(message) - -For making `Error`, `TypeError` and `RangeError` objects. - -```c++ -Local res = NanError("you must supply a callback argument"); -``` - - -### NanThrowError(message), NanThrowTypeError(message), NanThrowRangeError(message), NanThrowError(Local<Value>), NanThrowError(Local<Value>, int) - -For throwing `Error`, `TypeError` and `RangeError` objects. - -```c++ -NanThrowError("you must supply a callback argument"); -``` - -Can also handle any custom object you may want to throw. If used with the error code argument, it will add the supplied error code to the error object as a property called `code`. - - -### Local<Object> NanNewBufferHandle(char *, uint32_t), Local<Object> NanNewBufferHandle(uint32_t) - -The `Buffer` API has changed a little in Node 0.11, this helper provides consistent access to `Buffer` creation: - -```c++ -NanNewBufferHandle((char*)value.data(), value.size()); -``` - -Can also be used to initialize a `Buffer` with just a `size` argument. - -Can also be supplied with a `NanFreeCallback` and a hint for the garbage collector. - - -### Local<Object> NanBufferUse(char*, uint32_t) - -`Buffer::New(char*, uint32_t)` prior to 0.11 would make a copy of the data. -While it was possible to get around this, it required a shim by passing a -callback. So the new API `Buffer::Use(char*, uint32_t)` was introduced to remove -needing to use this shim. - -`NanBufferUse` uses the `char*` passed as the backing data, and will free the -memory automatically when the weak callback is called. Keep this in mind, as -careless use can lead to "double free or corruption" and other cryptic failures. - - -### bool NanHasInstance(Persistent<FunctionTemplate>&, Handle<Value>) - -Can be used to check the type of an object to determine it is of a particular class you have already defined and have a `Persistent` handle for. - - -### Local<Context> NanNewContextHandle([ExtensionConfiguration*, Handle<ObjectTemplate>, Handle<Value>]) -Creates a new `Local` handle. - -```c++ -Local ftmpl = NanNew(); -Local otmpl = ftmpl->InstanceTemplate(); -Local ctx = NanNewContextHandle(NULL, otmpl); -``` - - -### Local<Context> NanGetCurrentContext() - -Gets the current context. - -```c++ -Local ctx = NanGetCurrentContext(); -``` - - -### void NanDisposePersistent(Persistent<T> &) - -Use `NanDisposePersistent` to dispose a `Persistent` handle. - -```c++ -NanDisposePersistent(persistentHandle); -``` - - -### NanAssignPersistent(handle, object) - -Use `NanAssignPersistent` to assign a non-`Persistent` handle to a `Persistent` one. You can no longer just declare a `Persistent` handle and assign directly to it later, you have to `Reset` it in Node 0.11, so this makes it easier. - -In general it is now better to place anything you want to protect from V8's garbage collector as properties of a generic `Object` and then assign that to a `Persistent`. This works in older versions of Node also if you use `NanAssignPersistent`: - -```c++ -Persistent persistentHandle; - -... - -Local obj = NanNew(); -obj->Set(NanNew("key"), keyHandle); // where keyHandle might be a Local -NanAssignPersistent(persistentHandle, obj) -``` - - -### _NanWeakCallbackInfo<T, P>* NanMakeWeakPersistent(Handle<T>, P*, _NanWeakCallbackInfo<T, P>::Callback) - -Creates a weak persistent handle with the supplied parameter and `NAN_WEAK_CALLBACK`. - -```c++ -NAN_WEAK_CALLBACK(weakCallback) { - -... - -} - -Local func; - -... - -int *parameter = new int(0); -NanMakeWeakPersistent(func, parameter, &weakCallback); -``` - - -### NanSetTemplate(templ, name, value [, attributes]) - -Use to add properties on object and function templates. - - -### NanSetPrototypeTemplate(templ, name, value [, attributes]) - -Use to add prototype properties on function templates. - - -### NanSetInstanceTemplate(templ, name, value [, attributes]) - -Use to add instance properties on function templates. - - -### NanMakeCallback(target, func, argc, argv) - -Use instead of `node::MakeCallback` to call javascript functions. This is the only proper way of calling functions. - - -### NanCompileScript(Handle s [, const ScriptOrigin& origin]) - -Use to create new scripts bound to the current context. - - -### NanRunScript(script) - -Use to run both bound and unbound scripts. - - -### NanAdjustExternalMemory(int change_in_bytes) - -Simply does `AdjustAmountOfExternalAllocatedMemory`, note that the argument and returned value have type `int`. - - -### NanAddGCEpilogueCallback(GCEpilogueCallback callback, GCType gc_type_filter=kGCTypeAll) - -Simply does `AddGCEpilogueCallback` - - -### NanAddGCPrologueCallback(GCPrologueCallback callback, GCType gc_type_filter=kGCTypeAll) - -Simply does `AddGCPrologueCallback` - - -### NanRemoveGCEpilogueCallback(GCEpilogueCallback callback) - -Simply does `RemoveGCEpilogueCallback` - - -### NanRemoveGCPrologueCallback(GCPrologueCallback callback) - -Simply does `RemoveGCPrologueCallback` - - -### NanGetHeapStatistics(HeapStatistics *heap_statistics) - -Simply does `GetHeapStatistics` - - -### NanCallback - -Because of the difficulties imposed by the changes to `Persistent` handles in V8 in Node 0.11, creating `Persistent` versions of your `Handle` is annoyingly tricky. `NanCallback` makes it easier by taking your handle, making it persistent until the `NanCallback` is deleted and even providing a handy `Call()` method to fetch and execute the callback `Function`. - -```c++ -Local callbackHandle = args[0].As(); -NanCallback *callback = new NanCallback(callbackHandle); -// pass `callback` around and it's safe from GC until you: -delete callback; -``` - -You can execute the callback like so: - -```c++ -// no arguments: -callback->Call(0, NULL); - -// an error argument: -Handle argv[] = { - NanError(NanNew("fail!")) -}; -callback->Call(1, argv); - -// a success argument: -Handle argv[] = { - NanNull(), - NanNew("w00t!") -}; -callback->Call(2, argv); -``` - -`NanCallback` also has a `Local GetCallback()` method that you can use -to fetch a local handle to the underlying callback function, as well as a -`void SetFunction(Handle)` for setting the callback on the -`NanCallback`. You can check if a `NanCallback` is empty with the `bool IsEmpty()` method. Additionally a generic constructor is available for using -`NanCallback` without performing heap allocations. - - -### NanAsyncWorker - -`NanAsyncWorker` is an abstract class that you can subclass to have much of the annoying async queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the async work is in progress. - -See a rough outline of the implementation: - -```c++ -class NanAsyncWorker { -public: - NanAsyncWorker (NanCallback *callback); - - // Clean up persistent handles and delete the *callback - virtual ~NanAsyncWorker (); - - // Check the `ErrorMessage()` and call HandleOKCallback() - // or HandleErrorCallback depending on whether it has been set or not - virtual void WorkComplete (); - - // You must implement this to do some async work. If there is an - // error then use `SetErrorMessage()` to set an error message and the callback will - // be passed that string in an Error object - virtual void Execute (); - - // Save a V8 object in a Persistent handle to protect it from GC - void SaveToPersistent(const char *key, Local &obj); - - // Fetch a stored V8 object (don't call from within `Execute()`) - Local GetFromPersistent(const char *key); - - // Get the error message (or NULL) - const char *ErrorMessage(); - - // Set an error message - void SetErrorMessage(const char *msg); - -protected: - // Default implementation calls the callback function with no arguments. - // Override this to return meaningful data - virtual void HandleOKCallback (); - - // Default implementation calls the callback function with an Error object - // wrapping the `errmsg` string - virtual void HandleErrorCallback (); -}; -``` - - -### NanAsyncQueueWorker(NanAsyncWorker *) - -`NanAsyncQueueWorker` will run a `NanAsyncWorker` asynchronously via libuv. Both the *execute* and *after_work* steps are taken care of for you—most of the logic for this is embedded in `NanAsyncWorker`. - -### Contributors - -NAN is only possible due to the excellent work of the following contributors: - - - - - - - - -

These classes manage the underlying memory for you in a safer way than just handing off an allocated array. You should now `*NanAsciiString(handle)` to access the raw `char` data, you can also allocate on the heap if you need to keep a reference. -* Two more NanMakeCallback overloads have been added to for parity with Node core. -* You can now `NanNew(std::string)` (use `NanNew(std::string&)` to pass by reference) -* NanSetTemplate, NanSetPrototypeTemplate and NanSetInstanceTemplate have been added. - -### May-2014: 1.1.0 release - -* We've deprecated `NanSymbol()`, you should just use `NanNew()` now. -* `NanNull()`, `NanUndefined()`, `NanTrue()`, `NanFalse()` all return `Local`s now. -* `nan_isolate` is gone, it was intended to be internal-only but if you were using it then you should switch to `v8::Isolate::GetCurrent()`. -* `NanNew()` has received some additional overload-love so you should be able to give it many kinds of values without specifying the ``. -* Lots of small fixes and additions to expand the V8 API coverage, *use the source, Luke*. - - -### May-2014: Major changes for V8 3.25 / Node 0.11.13 - -Node 0.11.11 and 0.11.12 were both broken releases for native add-ons, you simply can't properly compile against either of them for different reasons. But we now have a 0.11.13 release that jumps a couple of versions of V8 ahead and includes some more, major (traumatic) API changes. - -Because we are now nearing Node 0.12 and estimate that the version of V8 we are using in Node 0.11.13 will be close to the API we get for 0.12, we have taken the opportunity to not only *fix* NAN for 0.11.13 but make some major changes to improve the NAN API. - -We have **removed support for Node 0.11 versions prior to 0.11.13**. As usual, our tests are run against (and pass) the last 5 versions of Node 0.8 and Node 0.10. We also include Node 0.11.13 obviously. - -The major change is something that [Benjamin Byholm](kkoopa) has put many hours in to. We now have a fantastic new `NanNew(args)` interface for creating new `Local`s, this replaces `NanNewLocal()` and much more. If you look in [./nan.h](nan.h) you'll see a large number of overloaded versions of this method. In general you should be able to `NanNew(arguments)` for any type you want to make a `Local` from. This includes `Persistent` types, so we now have a `Local NanNew(const Persistent arg)` to replace `NanPersistentToLocal()`. - -We also now have `NanUndefined()`, `NanNull()`, `NanTrue()` and `NanFalse()`. Mainly because of the new requirement for an `Isolate` argument for each of the native V8 versions of this. - -V8 has now introduced an `EscapableHandleScope` from which you `scope.Escape(Local value)` to *return* a value from a one scope to another. This replaces the standard `HandleScope` and `scope.Close(Local value)`, although `HandleScope` still exists for when you don't need to return a handle to the caller. For NAN we are exposing it as `NanEscapableScope()` and `NanEscapeScope()`, while `NanScope()` is still how you create a new scope that doesn't need to return handles. For older versions of Node/V8, it'll still map to the older `HandleScope` functionality. - -`NanFromV8String()` was deprecated and has now been removed. You should use `NanCString()` or `NanRawString()` instead. - -Because `node::MakeCallback()` now takes an `Isolate`, and because it doesn't exist in older versions of Node, we've introduced `NanMakeCallback()`. You should *always* use this when calling a JavaScript function from C++. - -There's lots more, check out the Changelog in nan.h or look through [#86](https://github.com/rvagg/nan/pull/86) for all the gory details. - -### Dec-2013: NanCString and NanRawString - -Two new functions have been introduced to replace the functionality that's been provided by `NanFromV8String` until now. NanCString has sensible defaults so it's super easy to fetch a null-terminated c-style string out of a `v8::String`. `NanFromV8String` is still around and has defaults that allow you to pass a single handle to fetch a `char*` while `NanRawString` requires a little more attention to arguments. - -### Nov-2013: Node 0.11.9+ breaking V8 change - -The version of V8 that's shipping with Node 0.11.9+ has changed the signature for new `Local`s to: `v8::Local::New(isolate, value)`, i.e. introducing the `isolate` argument and therefore breaking all new `Local` declarations for previous versions. NAN 0.6+ now includes a `NanNewLocal(value)` that can be used in place to work around this incompatibility and maintain compatibility with 0.8->0.11.9+ (minus a few early 0.11 releases). - -For example, if you wanted to return a `null` on a callback you will have to change the argument from `v8::Local::New(v8::Null())` to `NanNewLocal(v8::Null())`. - -### Nov-2013: Change to binding.gyp `"include_dirs"` for NAN - -Inclusion of NAN in a project's binding.gyp is now greatly simplified. You can now just use `" -## Usage - -Simply add **NAN** as a dependency in the *package.json* of your Node addon: - -``` bash -$ npm install --save nan -``` - -Pull in the path to **NAN** in your *binding.gyp* so that you can use `#include ` in your *.cpp* files: - -``` python -"include_dirs" : [ - "` when compiling your addon. - - -## Example - -See **[LevelDOWN](https://github.com/rvagg/node-leveldown/pull/48)** for a full example of **NAN** in use. - -For a simpler example, see the **[async pi estimation example](https://github.com/rvagg/nan/tree/master/examples/async_pi_estimate)** in the examples directory for full code and an explanation of what this Monte Carlo Pi estimation example does.

Same as `NAN_GETTER` but you also get a `Local` `value` object to work with. - - -### NAN_PROPERTY_GETTER(cbname) -Use `NAN_PROPERTY_GETTER` to declare your V8 accessible property getters. You get a `Local` `property` and an appropriately typed `args` object that can act similar to the `args` argument to a `NAN_METHOD` call. - -You can use `NanReturnNull()`, `NanReturnEmptyString()`, `NanReturnUndefined()` and `NanReturnValue()` in a `NAN_PROPERTY_GETTER`. - - -### NAN_PROPERTY_SETTER(cbname) -Use `NAN_PROPERTY_SETTER` to declare your V8 accessible property setters.

Same as `NAN_INDEX_GETTER`. - -You can use `NanReturnNull()`, `NanReturnEmptyString()`, `NanReturnUndefined()` and `NanReturnValue()` in a `NAN_INDEX_QUERY`. - - -### NAN_WEAK_CALLBACK(cbname) - -Use `NAN_WEAK_CALLBACK` to define your V8 WeakReference callbacks. There is an argument object `const _NanWeakCallbackData &data` allowing access to the weak object and the supplied parameter through its `GetValue` and `GetParameter` methods. You can even access the weak callback info object through the `GetCallbackInfo()`method, but you probably should not. `Revive()` keeps the weak object alive until the next GC round. - -```c++ -NAN_WEAK_CALLBACK(weakCallback) { - int *parameter = data.GetParameter(); - NanMakeCallback(NanGetCurrentContext()->Global(), data.GetValue(), 0, NULL); - if ((*parameter)++ == 0) { - data.Revive(); - } else { - delete parameter; - } -} -``` - - -### NAN_DEPRECATED -Declares a function as deprecated. - -```c++ -static NAN_DEPRECATED NAN_METHOD(foo) { - ... -} -``` - - -### NAN_INLINE -Inlines a function. - -```c++ -NAN_INLINE int foo(int bar) { - ... -} -``` - - -### Local<T> NanNew<T>( ... ) - -Use `NanNew` to construct almost all v8 objects and make new local handles. - -Note: Using NanNew with an std::string is possible, however, you should ensure -to use the overload version (`NanNew(stdString)`) rather than the template -version (`NanNew(stdString)`) as there is an unnecessary -performance penalty to using the template version because of the inability for -compilers to appropriately deduce to reference types on template specialization. - -```c++ -Local s = NanNew("value"); - -... - -Persistent o; - -... - -Local lo = NanNew(o); - -``` - - -### Local<Primitive> NanUndefined() - -Use instead of `Undefined()` - - -### Local<Primitive> NanNull() - -Use instead of `Null()` - - -### Local<Boolean> NanTrue() - -Use instead of `True()` - - -### Local<Boolean> NanFalse() - -Use instead of `False()` - - -### NanReturnValue(Handle<Value>) - -Use `NanReturnValue` when you want to return a value from your V8 accessible method: - -```c++ -NAN_METHOD(Foo::Bar) { - ... - - NanReturnValue(NanNew("FooBar!")); -} -``` - -No `return` statement required. - - -### NanReturnUndefined() - -Use `NanReturnUndefined` when you don't want to return anything from your V8 accessible method: - -```c++ -NAN_METHOD(Foo::Baz) { - ... - - NanReturnUndefined(); -} -``` - - -### NanReturnNull() - -Use `NanReturnNull` when you want to return `Null` from your V8 accessible method: - -```c++ -NAN_METHOD(Foo::Baz) { - ... - - NanReturnNull(); -} -``` - - -### NanReturnEmptyString() - -Use `NanReturnEmptyString` when you want to return an empty `String` from your V8 accessible method: - -```c++ -NAN_METHOD(Foo::Baz) { - ... - - NanReturnEmptyString(); -} -``` - - -### NanScope() - -The introduction of `isolate` references for many V8 calls in Node 0.11 makes `NanScope()` necessary, use it in place of `HandleScope scope` when you do not wish to return handles (`Handle` or `Local`) to the surrounding scope (or in functions directly exposed to V8, as they do not return values in the normal sense): - -```c++ -NAN_METHOD(Foo::Bar) { - NanScope(); - - NanReturnValue(NanNew("FooBar!")); -} -``` - -This method is not directly exposed to V8, nor does it return a handle, so it uses an unescapable scope: - -```c++ -bool Foo::Bar() { - NanScope(); - - Local val = NanFalse(); - ... - return val->Value(); -} -``` - - -### NanEscapableScope() - -The separation of handle scopes into escapable and inescapable scopes makes `NanEscapableScope()` necessary, use it in place of `HandleScope scope` when you later wish to return a handle (`Handle` or `Local`) from the scope, this is for internal functions not directly exposed to V8: - -```c++ -Handle Foo::Bar() { - NanEscapableScope(); - - return NanEscapeScope(NanNew("FooBar!")); -} -``` - - -### Local<T> NanEscapeScope(Handle<T> value); -Use together with `NanEscapableScope` to escape the scope. Corresponds to `HandleScope::Close` or `EscapableHandleScope::Escape`. - - -### NanLocker() - -The introduction of `isolate` references for many V8 calls in Node 0.11 makes `NanLocker()` necessary, use it in place of `Locker locker`: - -```c++ -NAN_METHOD(Foo::Bar) { - NanLocker(); - ... - NanUnlocker(); -} -``` - - -### NanUnlocker() - -The introduction of `isolate` references for many V8 calls in Node 0.11 makes `NanUnlocker()` necessary, use it in place of `Unlocker unlocker`: - -```c++ -NAN_METHOD(Foo::Bar) { - NanLocker(); - ... - NanUnlocker(); -} -``` - - -### void * NanGetInternalFieldPointer(Handle<Object>, int) - -Gets a pointer to the internal field with at `index` from a V8 `Object` handle. - -```c++ -Local obj; -... -NanGetInternalFieldPointer(obj, 0); -``` - -### void NanSetInternalFieldPointer(Handle<Object>, int, void *) - -Sets the value of the internal field at `index` on a V8 `Object` handle. - -```c++ -static Persistent dataWrapperCtor; -... -Local wrapper = NanNew(dataWrapperCtor)->NewInstance(); -NanSetInternalFieldPointer(wrapper, 0, this); -``` - - -### Local<Object> NanObjectWrapHandle(Object) - -When you want to fetch the V8 object handle from a native object you've wrapped with Node's `ObjectWrap`, you should use `NanObjectWrapHandle`: - -```c++ -NanObjectWrapHandle(iterator)->Get(NanNew("end")) -``` - - -### Local<String> NanSymbol(const char *) - -Deprecated. Use `NanNew` instead. -Use to create string symbol objects (i.e. `v8::String::NewSymbol(x)`), for getting and setting object properties, or names of objects. - -```c++ -bool foo = false; -if (obj->Has(NanNew("foo"))) - foo = optionsObj->Get(NanNew("foo"))->BooleanValue() -``` - - -### Type NanGetPointerSafe(Type *[, Type]) - -A helper for getting values from optional pointers. If the pointer is `NULL`, the function returns the optional default value, which defaults to `0`. Otherwise, the function returns the value the pointer points to. - -```c++ -char *plugh(uint32_t *optional) { - char res[] = "xyzzy"; - uint32_t param = NanGetPointerSafe(optional, 0x1337); - switch (param) { - ... - } - NanSetPointerSafe(optional, 0xDEADBEEF); -} -``` - - -### bool NanSetPointerSafe(Type *, Type) - -A helper for setting optional argument pointers. If the pointer is `NULL`, the function simply returns `false`. Otherwise, the value is assigned to the variable the pointer points to. - -```c++ -const char *plugh(size_t *outputsize) { - char res[] = "xyzzy"; - if !(NanSetPointerSafe(outputsize, strlen(res) + 1)) { - ... - } - - ... -} -``` - - -### void* NanRawString(Handle<Value>, enum Nan::Encoding, size_t *, void *, size_t, int) - -Deprecated. Use something else. - -When you want to convert a V8 `String` to a `char*` buffer, use `NanRawString`. You have to supply an encoding as well as a pointer to a variable that will be assigned the number of bytes in the returned string. It is also possible to supply a buffer and its length to the function in order not to have a new buffer allocated. The final argument allows setting `String::WriteOptions`. -Just remember that you'll end up with an object that you'll need to `delete[]` at some point unless you supply your own buffer: - -```c++ -size_t count; -void* decoded = NanRawString(args[1], Nan::BASE64, &count, NULL, 0, String::HINT_MANY_WRITES_EXPECTED); -... -delete[] reinterpret_cast(decoded); -``` - - -### char* NanCString(Handle<Value>, size_t *[, char *, size_t, int]) - -Deprecated. Use `NanUtf8String` instead. - -When you want to convert a V8 `String` to a null-terminated C `char*` use `NanCString`. The resulting `char*` will be UTF-8-encoded, and you need to supply a pointer to a variable that will be assigned the number of bytes in the returned string. It is also possible to supply a buffer and its length to the function in order not to have a new buffer allocated. The final argument allows optionally setting `String::WriteOptions`, which default to `v8::String::NO_OPTIONS`. -Just remember that you'll end up with an object that you'll need to `delete[]` at some point unless you supply your own buffer: - -```c++ -size_t count; -char* name = NanCString(args[0], &count); -... -delete[] name; -``` - - -### NanAsciiString - -Convert a `String` to zero-terminated, Ascii-encoded `char *`. - -```c++ -NAN_METHOD(foo) { - NanScope(); - NanReturnValue(NanNew(*NanAsciiString(arg[0]))); -} -``` - - -### NanUtf8String - -Convert a `String` to zero-terminated, Utf8-encoded `char *`. - -```c++ -NAN_METHOD(foo) { - NanScope(); - NanReturnValue(NanNew(*NanUtf8String(arg[0]))); -} -``` - - -### NanUcs2String - -Convert a `String` to zero-terminated, Ucs2-encoded `uint16_t *`. - -```c++ -NAN_METHOD(foo) { - NanScope(); - NanReturnValue(NanNew(*NanUcs2String(arg[0]))); -} -``` - - -### bool NanBooleanOptionValue(Handle<Value>, Handle<String>[, bool]) - -When you have an "options" object that you need to fetch properties from, boolean options can be fetched with this pair. They check first if the object exists (`IsEmpty`), then if the object has the given property (`Has`) then they get and convert/coerce the property to a `bool`. - -The optional last parameter is the *default* value, which is `false` if left off: - -```c++ -// `foo` is false unless the user supplies a truthy value for it -bool foo = NanBooleanOptionValue(optionsObj, NanNew("foo")); -// `bar` is true unless the user supplies a falsy value for it -bool bar = NanBooleanOptionValueDefTrue(optionsObj, NanNew("bar"), true); -``` - - -### uint32_t NanUInt32OptionValue(Handle<Value>, Handle<String>, uint32_t) - -Similar to `NanBooleanOptionValue`, use `NanUInt32OptionValue` to fetch an integer option from your options object. Can be any kind of JavaScript `Number` and it will be coerced to an unsigned 32-bit integer. - -Requires all 3 arguments as a default is not optional: - -```c++ -uint32_t count = NanUInt32OptionValue(optionsObj, NanNew("count"), 1024); -``` - - -### NanError(message), NanTypeError(message), NanRangeError(message) - -For making `Error`, `TypeError` and `RangeError` objects. - -```c++ -Local res = NanError("you must supply a callback argument"); -``` - - -### NanThrowError(message), NanThrowTypeError(message), NanThrowRangeError(message), NanThrowError(Local<Value>), NanThrowError(Local<Value>, int) - -For throwing `Error`, `TypeError` and `RangeError` objects. - -```c++ -NanThrowError("you must supply a callback argument"); -``` - -Can also handle any custom object you may want to throw. If used with the error code argument, it will add the supplied error code to the error object as a property called `code`. - - -### Local<Object> NanNewBufferHandle(char *, uint32_t), Local<Object> NanNewBufferHandle(uint32_t) - -The `Buffer` API has changed a little in Node 0.11, this helper provides consistent access to `Buffer` creation: - -```c++ -NanNewBufferHandle((char*)value.data(), value.size()); -``` - -Can also be used to initialize a `Buffer` with just a `size` argument. - -Can also be supplied with a `NanFreeCallback` and a hint for the garbage collector. - - -### Local<Object> NanBufferUse(char*, uint32_t) - -`Buffer::New(char*, uint32_t)` prior to 0.11 would make a copy of the data. -While it was possible to get around this, it required a shim by passing a -callback. So the new API `Buffer::Use(char*, uint32_t)` was introduced to remove -needing to use this shim. - -`NanBufferUse` uses the `char*` passed as the backing data, and will free the -memory automatically when the weak callback is called. Keep this in mind, as -careless use can lead to "double free or corruption" and other cryptic failures. - - -### bool NanHasInstance(Persistent<FunctionTemplate>&, Handle<Value>) - -Can be used to check the type of an object to determine it is of a particular class you have already defined and have a `Persistent` handle for. - - -### Local<Context> NanNewContextHandle([ExtensionConfiguration*, Handle<ObjectTemplate>, Handle<Value>]) -Creates a new `Local` handle. - -```c++ -Local ftmpl = NanNew(); -Local otmpl = ftmpl->InstanceTemplate(); -Local ctx = NanNewContextHandle(NULL, otmpl); -``` - - -### Local<Context> NanGetCurrentContext() - -Gets the current context. - -```c++ -Local ctx = NanGetCurrentContext(); -``` - - -### void NanDisposePersistent(Persistent<T> &) - -Use `NanDisposePersistent` to dispose a `Persistent` handle. - -```c++ -NanDisposePersistent(persistentHandle); -``` - - -### NanAssignPersistent(handle, object) - -Use `NanAssignPersistent` to assign a non-`Persistent` handle to a `Persistent` one. You can no longer just declare a `Persistent` handle and assign directly to it later, you have to `Reset` it in Node 0.11, so this makes it easier. - -In general it is now better to place anything you want to protect from V8's garbage collector as properties of a generic `Object` and then assign that to a `Persistent`. This works in older versions of Node also if you use `NanAssignPersistent`: - -```c++ -Persistent persistentHandle; - -... - -Local obj = NanNew(); -obj->Set(NanNew("key"), keyHandle); // where keyHandle might be a Local -NanAssignPersistent(persistentHandle, obj) -``` - - -### _NanWeakCallbackInfo<T, P>* NanMakeWeakPersistent(Handle<T>, P*, _NanWeakCallbackInfo<T, P>::Callback) - -Creates a weak persistent handle with the supplied parameter and `NAN_WEAK_CALLBACK`. - -```c++ -NAN_WEAK_CALLBACK(weakCallback) { - -... - -} - -Local func; - -... - -int *parameter = new int(0); -NanMakeWeakPersistent(func, parameter, &weakCallback); -``` - - -### NanSetTemplate(templ, name, value [, attributes]) - -Use to add properties on object and function templates. - - -### NanSetPrototypeTemplate(templ, name, value [, attributes]) - -Use to add prototype properties on function templates. - - -### NanSetInstanceTemplate(templ, name, value [, attributes]) - -Use to add instance properties on function templates. - - -### NanMakeCallback(target, func, argc, argv) - -Use instead of `node::MakeCallback` to call javascript functions. This is the only proper way of calling functions. - - -### NanCompileScript(Handle s [, const ScriptOrigin& origin]) - -Use to create new scripts bound to the current context. - - -### NanRunScript(script) - -Use to run both bound and unbound scripts. - - -### NanAdjustExternalMemory(int change_in_bytes) - -Simply does `AdjustAmountOfExternalAllocatedMemory`, note that the argument and returned value have type `int`. - - -### NanAddGCEpilogueCallback(GCEpilogueCallback callback, GCType gc_type_filter=kGCTypeAll) - -Simply does `AddGCEpilogueCallback` - - -### NanAddGCPrologueCallback(GCPrologueCallback callback, GCType gc_type_filter=kGCTypeAll) - -Simply does `AddGCPrologueCallback` - - -### NanRemoveGCEpilogueCallback(GCEpilogueCallback callback) - -Simply does `RemoveGCEpilogueCallback` - - -### NanRemoveGCPrologueCallback(GCPrologueCallback callback) - -Simply does `RemoveGCPrologueCallback` - - -### NanGetHeapStatistics(HeapStatistics *heap_statistics) - -Simply does `GetHeapStatistics` - - -### NanCallback - -Because of the difficulties imposed by the changes to `Persistent` handles in V8 in Node 0.11, creating `Persistent` versions of your `Handle` is annoyingly tricky. `NanCallback` makes it easier by taking your handle, making it persistent until the `NanCallback` is deleted and even providing a handy `Call()` method to fetch and execute the callback `Function`. - -```c++ -Local callbackHandle = args[0].As(); -NanCallback *callback = new NanCallback(callbackHandle); -// pass `callback` around and it's safe from GC until you: -delete callback; -``` - -You can execute the callback like so: - -```c++ -// no arguments: -callback->Call(0, NULL); - -// an error argument: -Handle argv[] = { - NanError(NanNew("fail!")) -}; -callback->Call(1, argv); - -// a success argument: -Handle argv[] = { - NanNull(), - NanNew("w00t!") -}; -callback->Call(2, argv); -``` - -`NanCallback` also has a `Local GetCallback()` method that you can use -to fetch a local handle to the underlying callback function, as well as a -`void SetFunction(Handle)` for setting the callback on the -`NanCallback`. You can check if a `NanCallback` is empty with the `bool IsEmpty()` method. Additionally a generic constructor is available for using -`NanCallback` without performing heap allocations. - - -### NanAsyncWorker - -`NanAsyncWorker` is an abstract class that you can subclass to have much of the annoying async queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the async work is in progress. - -See a rough outline of the implementation: - -```c++ -class NanAsyncWorker { -public: - NanAsyncWorker (NanCallback *callback); - - // Clean up persistent handles and delete the *callback - virtual ~NanAsyncWorker (); - - // Check the `ErrorMessage()` and call HandleOKCallback() - // or HandleErrorCallback depending on whether it has been set or not - virtual void WorkComplete (); - - // You must implement this to do some async work. If there is an - // error then use `SetErrorMessage()` to set an error message and the callback will - // be passed that string in an Error object - virtual void Execute (); - - // Save a V8 object in a Persistent handle to protect it from GC - void SaveToPersistent(const char *key, Local &obj); - - // Fetch a stored V8 object (don't call from within `Execute()`) - Local GetFromPersistent(const char *key); - - // Get the error message (or NULL) - const char *ErrorMessage(); - - // Set an error message - void SetErrorMessage(const char *msg); - -protected: - // Default implementation calls the callback function with no arguments. - // Override this to return meaningful data - virtual void HandleOKCallback (); - - // Default implementation calls the callback function with an Error object - // wrapping the `errmsg` string - virtual void HandleErrorCallback (); -}; -``` - - -### NanAsyncQueueWorker(NanAsyncWorker *) - -`NanAsyncQueueWorker` will run a `NanAsyncWorker` asynchronously via libuv. Both the *execute* and *after_work* steps are taken care of for you—most of the logic for this is embedded in `NanAsyncWorker`. - -### Contributors - -NAN is only possible due to the excellent work of the following contributors: - - - - - - - - -

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. - -module.exports = Transform; - -var Duplex = require('./_stream_duplex'); - -/**/ -var util = require('core-util-is'); -util.inherits = require('inherits'); -/**/ - -util.inherits(Transform, Duplex); - - -function TransformState(options, stream) { - this.afterTransform = function(er, data) { - return afterTransform(stream, er, data); - }; - - this.needTransform = false; - this.transforming = false; - this.writecb = null; - this.writechunk = null; -} - -function afterTransform(stream, er, data) { - var ts = stream._transformState; - ts.transforming = false; - - var cb = ts.writecb; - - if (!cb) - return stream.emit('error', new Error('no writecb in Transform class')); - - ts.writechunk = null; - ts.writecb = null; - - if (data !== null && data !== undefined) - stream.push(data); - - if (cb) - cb(er); - - var rs = stream._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - stream._read(rs.highWaterMark); - } -} - - -function Transform(options) { - if (!(this instanceof Transform)) - return new Transform(options); - - Duplex.call(this, options); - - var ts = this._transformState = new TransformState(options, this); - - // when the writable side finishes, then flush out anything remaining. - var stream = this; - - // start out asking for a readable event once data is transformed. - this._readableState.needReadable = true; - - // we have implemented the _read method, and done the other things - // that Readable wants before the first _read call, so unset the - // sync guard flag. - this._readableState.sync = false; - - this.once('finish', function() { - if ('function' === typeof this._flush) - this._flush(function(er) { - done(stream, er); - }); - else - done(stream); - }); -} - -Transform.prototype.push = function(chunk, encoding) { - this._transformState.needTransform = false; - return Duplex.prototype.push.call(this, chunk, encoding); -}; - -// This is the part where you do stuff! -// override this function in implementation classes. -// 'chunk' is an input chunk. -// -// Call `push(newChunk)` to pass along transformed output -// to the readable side.
