Webpack Babel Starter

A webpack 2 starter kit with full development & build workflow, inspired by topheman/react-es6-redux.

What's in this boilerplate:

• Development / Build / Lint tasks
• Babel transpiler
• Eslint / babel-eslint / eslint-config-airbnb-base
• Sass support
• Ship a version of your site with sourcemaps (see demo)

Already in use in the following projects:

• topheman/rxjs-experiments (RxJS) (switched to v2)
• topheman/react-es6-redux (React/Redux/Github Api) - since v3.0.0 (using v1)
• topheman/d3-react-experiments (React/d3) (switched to v2 + setup [email protected])

I also have ported it on topheman/angular2-sandbox to be used the same way in an Angular2 / TypeScript project (using v1).

Install

git clone https://github.com/topheman/webpack-babel-starter.git
cd webpack-babel-starter
npm install

Run

npm start

Goto http://localhost:8080

If you need to access from a remote device (such as a smartphone on the same network), just LOCALHOST=false npm start and your site will be accessible via your IP (which will be output on the terminal at launch).

Build

The ./build directory is ignored by git, it will contain a dist directory which holds the distribution version of your website (the one that you will ship once built).

All the build tasks will create a built version of the project in the ./build/dist folder, cleaning it before making the build.

• npm run build
• npm run build-prod optimized / uglified version
• npm run build-prod-all will build:
  • production version (optimized / uglified)
  • a debuggable version accessible at /devtools shipping all the sourcemaps, to ease sharing transpiled source code

npm run serve-dist will serve your ./build/dist folder at http://localhost:3000 so that you could test the built version you just made.

Linter

• eslint is running while you're developping, check your console for errors
• you can also launch it via npm run lint
• see .eslintrc for the configuration (currently, this project uses the airbnb presets - if you find it to restrictive, just remove "extends": "airbnb-base" in the .eslintrc)

Customizations

You can customize the behavior of the scripts by specifying environments vars:

• NODE_ENV by default at development, NODE_ENV=production when you npm run build-prod
• LINTER=false will disable the linter (enabled by default, ex: LINTER=false npm start)
• STATS=true will write stats.json profiling file on disk from webpack at build (disabled by default, ex: STATS=true npm run build)
• FAIL_ON_ERROR=true will break the build if any errors occurs (useful for CIs such as travis - at false in dev-server, at true when building)
• LOCALHOST=false to access via IP from other devices on the same network (ex: LOCALHOST=false npm start - default true)
• DEVTOOLS: By default at null. Used internally by npm run build-prod-all (you may not need that if you don't do OSS)

Assets

The main image loaders are declared in the webpack config so that when you require('./foo.png') or use the helper url('./bar.gif') in your .scss files, at build time, those images will automatically be:

• copied into /build/dist/assets
• there name will be hashed (without you bothering with the reference in the generated code)
• the hashed name will only change if the file changes (caching & git friendly)
• I made sure that the css supports relative urls (this is why main.css lands at the same level as index.html)

FAQ / Deploy

• deploy on github pages - see wiki
• a problem ? Checkout the FAQ
• Using React ? Checkout how I integrated all the usual tools around React on some of my own projects, based on this boilerplate.

Bonus

Check the source code of the html/js/css generated files, you'll see a banner containing informations such as:

• date the build was made
• version
• git revision / link to this revision on github

Contributing

PRs are welcome, just keep in mind this boilerplate aims to keep beeing framework agnostic.

Everything related to contributing (tests, framework dependencies ...) is located in the /contributing folder. Check the readme in there to see how to setup your workspace.

Versions

v3 (current)

• Dropped yarn for [email protected] (you remain free to choose whatever package manager you want, the project is compatible with both yarn and npm).

v2

Still available on this branch.

Migrated to webpack2. The workflow and the npm tasks remain exactly the same.

If you were using the v1 with webpack1, the webpack team has a migrating path. You can also see the steps I followed to migrate this stack from v1 to v2:

• setup yarn (unrelated to webpack)
• minimal changes for migration to webpack v2
• upgrade eslint
• code splitting with import()
• upgrade minor dependencies

v1

Still available on this branch.

First version, using webpack1.
