What is a PWA     

A Progressive Web App (PWA) is a web app that uses modern web capabilities to deliver an app-like experience to users. These apps meet certain requirements (see below), are deployed to web servers and accessible through URLs (on HTTPS protocol).

This can work in conjunction with Cordova to provide a multiple deploy targets for all your users. Quasar CLI allows you to deploy your app as a PWA as well as a Mobile app and take advantage of both channels.

Manifest File

An app manifest file describes the resources your app will need. This includes your app’s displayed name, icons, as well as splash screen. Quasar CLI configures this for you, but you can override any property from within /quasar.conf.js. Learn how by visiting the Configure PWA documentation page.

A full-blown Service Worker is not available during development due to the fact that it is not compatible with HMR (Hot Module Reload). So, as opposed to production code, development has a very simple Service Worker that just invalidates cache. Take a look at /src-pwa for the two service workers used. You can change these files to meet your needs.
