Getting started with the Ionic PWA Toolkit

  1. In your terminal, run:
    git clone https://github.com/ionic-team/ionic-pwa-toolkit my-pwa
  2. Run npm install
  3. Run npm run build

And with just those three commands you now have a great looking PWA that scores 100 on lighthouse right out of the box.

Under the hood


The Ionic PWA Toolkit uses an early release of Ionic 4. Ionic 4 is built completely out of web components using Stencil. This means that you can use Ionic 4 just like any other Stencil collection and you will be able to use any of the Ionic components with minimal to no overhead.


The Ionic PWA Toolkit uses the Stencil Router. Read more about the Stencil Router

Service Worker

When you run npm run build we automatically generate a Service Worker for you using Workbox that handles pre-caching your assets. Read more about Service Workers

Web Manifest

By default we include a Web Manifest that has all the neccessary entries to get the Add to Homescreen prompt. You can see that web manifest here .
