Snek

A snake clone in elm

Available scripts

In the project directory you can run:

elm-app build

Builds the app for production to the build folder.

The build is minified, and the filenames include the hashes. Your app is ready to be deployed!

elm-app start

Runs the app in the development mode. Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits. You will also see any lint errors in the console.

You may change the listening port number by using the PORT environment variable. For example type PORT=8000 elm-app start into the terminal/bash to run it from: http://localhost:8000/.

elm-app install

Alias for elm install

Use it for installing Elm packages from package.elm-lang.org

elm-app test

Run tests with node-test-runner

You can make test runner watch project files by running:

elm-app test --watch

Deployment

elm-app build creates a build directory with a production build of your app. Set up your favourite HTTP server so that a visitor to your site is served index.html, and requests to static paths like /static/js/main.<hash>.js are served with the contents of the /static/js/main.<hash>.js file.

Building for Relative Paths

By default, Create Elm App produces a build assuming your app is hosted at the server root.

To override this, specify the homepage in your elmapp.config.js, for example:

module.exports = {
    homepage: "http://mywebsite.com/relativepath"
}

This will let Create Elm App correctly infer the root path to use in the generated HTML file.

GitHub Pages

Step 1: Add homepage to elmapp.config.js

The step below is important!

If you skip it, your app will not deploy correctly.

Open your elmapp.config.js and add a homepage field:

module.exports = {
    homepage: "https://myusername.github.io/my-app",
}

Create Elm App uses the homepage field to determine the root URL in the built HTML file.

Step 2: Build the static site

elm-app build

Step 3: Deploy the site by running gh-pages -d build

We will use gh-pages to upload the files from the build directory to GitHub. If you haven't already installed it, do so now (npm install -g gh-pages)

Now run:

gh-pages -d build

Step 4: Ensure your project’s settings use gh-pages

Finally, make sure GitHub Pages option in your GitHub project settings is set to use the gh-pages branch:

Step 5: Optionally, configure the domain

You can configure a custom domain with GitHub Pages by adding a CNAME file to the public/ folder.
