A full-featured Webpack setup with hot-reload, lint-on-save, unit testing & css extraction.

This boilerplate is targeted towards large, serious projects and contains a lot of moving pieces. If you just want to try out vue-loader or whip out a quick prototype, use the webpack-simple template instead.

This is a project template for vue-cli. It is recommended to use npm 3+ for a more efficient dependency tree.

$ npm install -g vue-cli
$ vue init webpack my-project
$ cd my-project
$ npm install
$ npm run dev

• npm run dev: first-in-class development experience.

  • Webpack + vue-loader for single file Vue components.
  • State preserving hot-reload
  • State preserving compilation error overlay
  • Lint-on-save with ESLint
  • Source maps

• npm run build: Production ready build.

  • JavaScript minified with UglifyJS.
  • HTML minified with html-minifier.
  • CSS across all components extracted into a single file and minified with cssnano.
  • All static assets compiled with version hashes for efficient long-term caching, and a production index.html is auto-generated with proper URLs to these generated assets.
  • Also see deployment notes.

• npm run unit: Unit tests run in PhantomJS with Karma + Jasmine + karma-webpack.

  • Supports ES2015 in test files.
  • Supports all webpack loaders.
  • Easy mock injection.

• npm run e2e: End-to-end tests with Nightwatch.

  • Run tests in multiple browsers in parallel.
  • Works with one command out of the box:
    • Selenium and chromedriver dependencies automatically handled.
    • Automatically spawns the Selenium server.

For a better understanding of how things work, consult the docs for respective projects listed. In particular, Webpack and vue-loader.

• What's the difference between src/assets/ and static/?

  Files inside src/assets/ should be referenced via relative paths inside Vue component templates and styles. This allows them to be processed by webpack using url-loader and file-loader before copied into /static. This allows you to leverage features such as file naming with hashes for better caching and conditional base-64 inline-ing. You can even add image-optimizing loaders to automatically optimize these images during build.

  Files inside static/ are copied directly without modification; they can be reference anywhere via root-relative paths that start with /static/. This is an escape hatch when you want certain assets to completely bypass webpack.

• How do I configure the linting rules?

  The project uses Standard code style via ESLint. You can override the rules in .eslintrc.js, for example allowing semicolons by adding "semi": [2, "always"].

  Alternatively you can use a different config altogether, for example eslint-config-airbnb. Install it and change the "extends" field in .eslintrc.js.

• How do I use a CSS pre-processor inside *.vue files?

  First, install the corresponding loader (and their peer dependencies), e.g. to use LESS:

  npm install less-loader less --save-dev

  Then in your *.vue files, use <style lang="less">. The CSS extraction has been pre-configured to work with most popular pre-processors.

  For SASS:

  npm install sass-loader node-sass --save-dev

  Note that lang="sass" assumes SASS's indented syntax; Use lang="scss" if you want the CSS-superset syntax.

• How do I work with an existing backend server during development?

  You can edit proxyTable in build/dev-server.js to proxy certain requests to your backend server.

• How do I deploy built assets with my backend framework?

  Your backend framework may come with a convention for where static assets should live, and the default generated file structure may need to be adjusted. Here's what you need to do:

  • Edit output.publicPath to be the URL path where your backend framework serves static assets, e.g. /public/.

  • After running npm run build, copy the contents of dist/index.html into the appropriate server-side template, and copy everything in dist/static to the public/static directory of your backend framework. You can automate this by adding custom scripts in build/build.js.

• How do I run unit tests in more browsers?

  You can run the tests in multiple real browsers by installing more karma launchers and adjusting the browsers field in test/unit/karma.conf.js.

• How do I run e2e tests in more browsers?

  To configure which browsers to run the tests in, add an entry under "test_settings" in test/e2e/nightwatch.conf.js , and also the --env flag in test/e2e/runner.js. If you wish to configure remote testing on services like SauceLabs, you can either make the nightwatch config conditional based on environment variables, or use a separate config file altogether. Consult Nightwatch's docs for more details.

• Is there a way to prerender certain routes for SEO?

  If you want to prerender routes that will not significantly change once pushed to production, use this Webpack plugin: prerender-spa-plugin, which has been tested for use with Vue. For pages that do frequently change, Prerender.io and Netlify both offer plans for regularly re-prerendering your content for search engines.

You can fork this repo to create your own boilerplate, and use it with vue-cli:

vue init username/repo my-project
