Discover the process of integrating PWA features into an Express web application

I'm currently in the process of integrating PWA into a web application. I've created a manifest.json file and added it to the head of my page, which is loading correctly. However, the service worker registered in my app.js doesn't seem to be functioning as expected.

Here's the code snippet I'm using to set up the app:

const express = require("express")
const path = require('path')
const chalk = require('chalk')
const debug = require('debug')('app')
...

This is the code for my service worker:

var contentToCache = [
    './',
    'src/views/alcoholListView.ejs',
    ...
]
self.addEventListenent('install', function (e) {
    console.log('[Service Worker] Install')
...

Any insights on why my application isn't being recognized as a PWA would be greatly appreciated. Thanks!

Answer №1

The initial section of your code operates on the server, but the service-worker runs on browsers in the client side. Therefore, the condition if('serviceWorker' in navigator) will always be false. To correct this issue, you need to include

if('serviceWorker' in navigator){ navigator.serviceWorker.register('sw.js') }
in the app.js file specifically for the client side located within the /public directory.
