Release notes

Sourced from webpack's releases.

v5.107.2

Patch Changes

• Reduce per-file overhead in ContextModuleFactory.resolveDependencies by batching alternativeRequests hook calls. Previously the hook was invoked once per file in the context (with a single-item array), paying per-call overhead (closure allocation, resolverFactory.get, intermediate arrays in RequireContextPlugin) for every file. The hook is now invoked once per directory with all matched files in one batch — RequireContextPlugin's tap already iterates the items array, so the output is unchanged. Steady-state rebuild on a 4000-file require.context drops a further ~15 ms (after the watch-mode purge fix in the same release). (by @​alexander-akait in #21020)

• Include each external info's runtimeCondition in ConcatenatedModule#updateHash so changes to a concatenated external's runtime condition invalidate persistent caches instead of slipping through with the module id alone. (by @​alexander-akait in #21023)

• Fix HTML [contenthash] for referenced asset and inline-style URL changes. (by @​alexander-akait in #21018)

• Resolve chunk-hash placeholders in chunk URLs embedded into extracted HTML. (by @​alexander-akait in #21018)

• Remove unnecessary __webpack_require__ runtime helpers in ESM library output with multi-module chunks. (by @​xiaoxiaojx in #21032)

• Rewrite NormalModule#getSideEffectsConnectionState walk as an allocation-light iterative loop instead of a generator trampoline, restoring rebuild performance lost in #20993 while keeping deep import chains stack-safe. (by @​alexander-akait in #21014)

• Fix runtime ReferenceError on the first activation of a lazy-compiled module when output.library.type produces a closure-wrapped bundle (umd, umd2, amd, amd-require, system). (by @​alexander-akait in #21013)

  External modules of these types reference closure-bound identifiers like __WEBPACK_EXTERNAL_MODULE_react__, supplied by the library wrapper that is generated once per chunk. When lazyCompilation activates an entry or import for the first time, any external dependency the lazily-built module pulls in arrives in a hot-update chunk that lives outside the original wrapper closure, so its factory body cannot resolve the closure identifier and only a manual page refresh recovers.

  The inactive LazyCompilationProxyModule now declares statically-enumerable externals (string and object forms of externals) as its own dependencies, so the initial entry chunk's library wrapper already exposes their closure identifiers. When activation later pulls in those externals through the lazily-compiled module, they resolve to the already-installed factories instead of throwing. Function and RegExp externals are not pre-populated because their effective request set isn't knowable up front.

• Fill in missing entryOptions when an async block joins an existing entrypoint. (by @​alexander-akait in #21026)

• Release per-child codeGenerationResults in MultiCompiler and at Compiler.close to reduce memory retention. (by @​alexander-akait in #21015)

• Reduce peak memory of SourceMapDevToolPlugin on large builds (closes #20961). (by @​alexander-akait in #20963)

• Fix slow require.context() / dynamic import() rebuilds in watch mode (#13636). When a file inside a watched context directory changed, NodeWatchFileSystem would call inputFileSystem.purge(contextDir). The enhanced-resolve purge implementation matches cache keys with key.startsWith(contextDir), so the stat cache of every file under the directory was discarded on every rebuild — ContextModuleFactory.resolveDependencies then re-stat-ed the whole tree on each rebuild. Single-file rebuilds on a 4000-file context now reuse the warm stat cache, dropping median rebuild from ~1260 ms to ~650 ms in a local reproduction (≈49%). For directory items that are explicitly watched contexts, purge is now called with { exact: true } (added in enhanced-resolve@5.22.0) so only the directory's own entry is invalidated; file-level changes in the same aggregated event continue to purge file stats and the parent readdir as before. (by @​alexander-akait in #21020)

v5.107.1

Patch Changes

• Align the experimental HTML tokenizer with the WHATWG spec: fix offset-range bugs in the script-data, content-mode end-tag, attribute-value, and EOF states; surface tokenizer parse errors to consumers via a new parseError callback ("warning" when the tokenizer recovers and the emitted token is still well-formed, "error" when the offset range is incomplete — e.g. eof-in-tag); and add the full WHATWG named character references table so decodeHtmlEntities handles all named entities (including legacy bare forms like &AMP and multi-code-point entities like ≂̸) with proper longest-prefix backtracking. (by @​alexander-akait in #21000)

• Tree-shake CommonJS modules imported through a const NAME = require(LITERAL) binding when only static members of NAME are read. Previously webpack treated every export of such modules as referenced (because the bare require() dependency reports EXPORTS_OBJECT_REFERENCED), so unused exports.x = ... assignments remained in the bundle even with usedExports enabled. The parser now forwards NAME.x / NAME.x() / NAME["x"] accesses to the underlying CommonJsRequireDependency as referenced exports, falling back to the full exports object the moment NAME is read in any other context (passed by value, destructured later, accessed with a dynamic key, …). This brings the binding form to parity with the existing destructuring form (const { x } = require(...)). (by @​alexander-akait in #21003)

• Fix RangeError: Maximum call stack size exceeded thrown from HarmonyImportSideEffectDependency.getModuleEvaluationSideEffectsState on long linear chains of side-effect-free imports. NormalModule.getSideEffectsConnectionState previously descended through HarmonyImportSideEffectDependency.getModuleEvaluationSideEffectsState recursively, adding two stack frames per module, which overflowed V8's stack at a few thousand modules deep. The traversal is now iterative. (by @​alexander-akait in #20993)

• Fix NormalModuleFactory parser/generator types: (by @​alexander-akait in #20999)

  • module.generator.html now uses HtmlGeneratorOptions instead of EmptyGeneratorOptions (the extract option was hidden from the createGenerator / generator hook types).
  • WebAssembly (webassembly/async, webassembly/sync) generator hooks now use EmptyGeneratorOptions instead of EmptyParserOptions.
  • NormalModuleFactory#getParser / createParser / getGenerator / createGenerator are now generic over the module-type string, returning the specific parser/generator class for known types (e.g. JavascriptParser for "javascript/auto", CssGenerator for "css", etc.) instead of always returning the base Parser / Generator.
  • NormalModuleCreateData is now generic over the module type so parser, parserOptions, generator, and generatorOptions are narrowed to the specific class / options for the given type.

• Link import bindings used inside define(...) callbacks in ES modules. Previously, HarmonyDetectionParserPlugin skipped walking the arguments of define calls in harmony modules, so references to imported bindings inside an inline AMD define factory (e.g. define(function () { console.log(foo); })) were not rewritten to their imported references and could cause ReferenceError at runtime. Inner graph usage analysis is also fixed for the related pattern const fn = function () { foo; }; define(fn);. (by @​alexander-akait in #20990)

• HTML-entry pipeline (experiments.html + experiments.css): emit <link rel="stylesheet"> tags for CSS chunks reachable from a <script src> entry. Previously when the bundled JS imported CSS, the resulting .css file was emitted to disk but never referenced from the extracted HTML (no <link> tag), and when splitChunks extracted CSS into sibling chunks the HTML cloned the originating <script> for each one — producing <script src="style.js"> pointing at non-existent JS filenames instead of <link rel="stylesheet" href="style.css">. CSS chunks are now sorted by the entrypoint's module post-order index so the <link> tags also appear in source import order, fixing the cascade ordering issue documented in html-webpack-plugin#1838 and webpack/mini-css-extract-plugin#959 for HTML-entry builds. nonce/crossorigin/referrerpolicy are copied from the originating tag onto the emitted <link>. (by @​alexander-akait in #21002)

• Allow devtool and SourceMapDevToolPlugin (or multiple SourceMapDevToolPlugin instances) to coexist on the same asset. Previously the second instance would silently skip any asset whose info.related.sourceMap had already been set by an earlier instance, and even when it ran the asset had been rewrapped as a RawSource so no source map could be recovered — producing an empty .map file. The plugin now keeps a per-compilation stash of pristine source maps, namespaces its persistent cache entries by the options that affect output, and appends additional related.sourceMap entries instead of overwriting them. The classic workaround of pairing devtool: 'hidden-source-map' with a new webpack.SourceMapDevToolPlugin({ filename: '[file].secondary.map', noSources: true }) now produces both maps in a single build.
