PWA and Django #Installing a PWA as a native application

This tutorial shows how to enable native installation for your Progressive Web App (PWA) built with Django. It's surprisingly simple and highly beneficial for user experience.

Enabling Native Installation

A small code addition prompts users to install your PWA as a native application.

let beforeInstallPromptEvent = null;
let installed = false;

async function installPWA() {
   if (beforeInstallPromptEvent === null || installed) {
       return;
   }

   try {
       beforeInstallPromptEvent.prompt();

       const { outcome } = await beforeInstallPromptEvent.userChoice;
       if (outcome === 'accepted') {
           console.log("App install dialog accepted!");
           beforeInstallPromptEvent = null;
           installed = true;
       }

   } catch(e) {
       console.error(e);
   }
}

Event listeners refine the installation process:

window.addEventListener('beforeinstallprompt', (e) => {
   beforeInstallPromptEvent = e;
});

window.addEventListener('appinstalled', () => {
   installed = true;
});

An "Install" button triggers the installation prompt:

The browser displays an installation dialog:

Upon acceptance, the PWA is registered with its own launcher icon:

Running as a Standalone App

After installation, the PWA launches in its own window, leveraging manifest-defined styling for a more native feel:

Remember, the PWA manifest lets you customize icons, behavior, colors, etc. Learn more:
