Looking for a simple way to add PWA push notifications?
Progressive Web Apps (PWAs) are apps that work on any device. But there’s always some conflict with sending web push notifications. Usually, the biggest problem is the delivery rates. You can add web push to your PWA in many ways. But how do you send web push notifications that actually get delivered from your PWA?
Don’t worry! In this article, we’re going to show you step-by-step how you can send PWA push notifications with reliable delivery rates in less than 10 minutes.
Plongeons dans le vif du sujet.
TL;DR — What is PWA push? Progressive Web App (PWA) push notifications are standard web push messages delivered through a PWA’s registered service worker, allowing apps installed from the web to receive push messages even when the web page is closed.

Les notifications push sont un outil marketing super efficace et peu coûteux pour vous aider à augmenter votre trafic de retour, votre engagement et vos ventes en mode automatique.
How to Install PWA Push Notifications
Adding push notifications to a Progressive Web App is quite simple. Just follow the steps in this article. If you follow every step, by the end of this article, you should be able to send push notifications like this one:

- Register a service worker at the site root that combines PWA logic and push handling.
- Install PushEngage script and copy installation code into
<head>. - Configure the opt-in modal and create a campaign in the PushEngage dashboard.
The main challenge is that all web push notification software uses a Javascript file called service_worker.js. The service worker helps you collect push notification subscribers through popup modals. But all PWAs already have a service worker file that serves a different purpose. And at a time, your PWA can only use one service worker.
In simple words, web push services confuse your PWA. So, sometimes it will collect push notification subscribers and sometimes, it won’t. Sometimes you can send notifications and sometimes you can’t. You might even end up sending push messages to your entire subscriber list and have it delivered only to a few subscribers.
We recommend using PushEngage to send PWA push notifications. PushEngage is the #1 push notification software in the world. So, you know that your campaigns are in safe hands.
Of course, PWA builders like Mendix come with their own push notification system. But what if you want to migrate to some other push notification service? What if you want more flexibility and control over your push notification campaigns? What’s more is that these services typically give you an API to create push campaigns. But with PushEngage, you get an easy to use dashboard from which you can create, schedule, send, and manage push campaigns.
And yes, you can use Firebase Cloud Messaging (FCM) to send Android app push notifications. But with PushEngage, you can send Android app and web push notifications, iOS and iPadOS web and app push notifications, and browser push notifications.
The best part? You can even send powerful eCommerce push notifications with a few clicks.

Étape n°1 : Configurer votre compte PushEngage
Rendez-vous sur la page d'accueil de PushEngage et cliquez sur le bouton Commencer :
You can try out PushEngage for free. If you’re running a small blog that needs repeat traffic and engagement, that’s probably good enough. But if you’re serious about sales, you should get the Enterprise package and unlock the automated campaigns.
Une fois que vous avez créé votre compte PushEngage, rendez-vous sur votre tableau de bord PushEngage et allez dans Paramètres du site » Détails du site :

Vous pouvez y définir votre logo, le nom de votre site et l'URL de votre site. Il est très important de régler ces éléments dès maintenant afin de pouvoir tester toute votre configuration plus tard.
Étape n°2 : Obtenir le code d'installation de PushEngage

Ensuite, cliquez sur l'onglet N'importe quel site :

Vous pouvez utiliser le code Javascript pour commencer à envoyer des notifications push.
Step #3: Add the Service Worker Code For PWA Push Notifications
The most tricky part of the process is finally here. In the PushEngage dashboard under Setup Instructions, you’ll also see an option to download the service worker file.

IMPORTANT: A PWA can only have one active service worker scope at a time — merge push code into your existing service worker. By default, a PWA doesn’t require a service worker file. All you need to turn any site into a Progressive Web App is a manifest file. So, if your PWA doesn’t have a service worker file, then you can simply add the PushEngage service worker to the root directory of your website or web app.
But if your PWA already has a service worker in place, then DO NOT directly upload the PushEngage push notification service worker file as is. Open the PushEngage service worker in a text editor like Notepad and copy the code in the PushEngage service worker file. Then, find the service worker file for your PWA and simply add the PushEngage service worker code to the file.
If you neglect this step, you won’t be able to collect push notification subscribers.
