Could someone please provide detailed instructions on how to implement a messaging and notification function using Firebase? Note that this is for the web version, not mobile. Thank you.
hello, here is the steps for you asked about the firebase
Create a project in Firebase and enable Firestore + FCM
Add the Firebase Web SDK in OutSystems using JavaScript (via an External Library or JS block)
Use Firestore to store messages and listen for updates (real-time chat works)
Create firebase-messaging-sw.js at the app root (required for web notifications)
Ask notification permission in a JS block and generate the FCM token
Store the token in an OutSystems entity mapped to the logged-in user
Trigger notifications from Firebase Cloud Functions or your OutSystems server REST API (never from client JS)
Run the app over HTTPS
It's correct! Very detail.
