PWA built with the Ionic PWA toolkit. Really just a demo of the toolkit itself.

Ionic PWA Toolkit

The Ionic PWA Toolkit is the recommended way to build production ready PWAs with Ionic. This toolkit gets you started with using Stencil, Ionic Core and Ionic PWA hosting. This combination of tools gives you the ability to build a fast, efficient PWA with zero config needed and all the best practices built in out of the box.

What does this include

• Stencil
• Ionic
• Push Notifications setup
• Showing a toast when a new version of the PWA is available
• Unit Tests
• Pre-rendering
• zero config lazy loading
• zero config code splitting
• Polyfills selectively loaded depending on the browser support
• ES6 by default for new browsers, ES5 for older browsers
• Everything needed for an add to homescreen PWA (service worker, web manifest and iOS meta tags)
• lazy-img component for lazy loading below the fold images

Getting Started

To start building a PWA with the Ionic PWA Toolkit, clone this repo to a new directory:

git clone https://github.com/ionic-team/ionic-pwa-toolkit.git my-pwa
cd my-pwa
git remote rm origin

and run:

npm install
npm start

Production

To build your PWA for production, run:

npm run build

A production build includes everything needed for your project to be a PWA right out of the box. This includes both a Web Manifest (src/manifest.json) and a Service Worker (www/sw.js).

Service Workers

For info on how Service Workers work in Stencil check out our Service Worker docs.

Developing with a Service Worker

In some cases, for instance when you are working on adding web push notifications or background sync, both which require a Service Worker, it can be handy to be able to dev builds with a service worker.

To do this with the Ionic PWA toolkit simply run npm run devWithSW. This will start a dev build, but with the Service Worker also getting livereloaded.

Unit Tests

To run the unit tests once, run:

npm test

To run the unit tests and watch for file changes during development, run:

npm run test.watch

Testing your PWA's performance

We recommend using https://www.webpagetest.org/easy with the Run Lighthouse Audit option turned on. This will give you an in depth look into your PWAs load performance on the average device connected to the average network.
