vue-pwa-boilerplate

A full-featured PWA template with webpack, hot-reload, lint-on-save, unit testing & css extraction.

Documentation

• This template builds on top of the main webpack template, so please refer to the webpack template docs.

• Check out the official Vue.js guide for general information about Vue that is not specific to this template.

Usage

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

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

If port 8080 is already in use on your machine you must change the port number in /config/index.js. Otherwise npm run dev will fail.

What's not Included

• You should configure your web server to add HTTP headers to prevent caching of critical service worker files. If you don't do this, browsers might cache the content for up to 24 hours. In addition, you should add HTTP headers to prevent the contents of the static folder to be cached unintentionally long.

See "Configuring your Web server to prevent caching" in the docs for more information.

What's Included

• Service Worker precaching of application shell + static assets (prod)
• Script (async chunk) preloading using <link rel="preload">
• Web Application Manifest + favicons
• Mobile-friendly meta-viewport
• Lighthouse score of 90+/100

• 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.
  • Use npm run build --reportto build with bundle size analytics.
  • Generates a Service Worker for offline caching your static assets using sw-precache-webpack-plugin

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

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

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

Contributing

This project is a modified copy of the vue-webpack-boilerplate template.

While we welcome contributions from the community, please note that changes to configuration that is shared between this project and vue-webpack-boilerplate should be made against vue-webpack-boilerplate first.

Once the upstream PR is merged, please file an additional PR against this project making the equivalent changes. This will help ensure that the shared configuration does not diverge too much.

Any changes that are specific to this project—related to service workers, or other PWA functionality—do not need an equivalent upstream PR.
