How can I implement firestore database trigger (onCreate, onUpdate) with Cloud functions for firebase gen 2 ?

As in Firestore cloud function gen1 we can use Cloud firestore database triggers, But how can we implement this in Firestore cloud function gen 2

I am successfully listening for events from Firestore v2 via Gen 2 Functions. You can give something like below a try in your index.js if using Node.js Functions.

const {initializeApp} = require("firebase-admin/app");
const {onDocumentUpdated} = require("firebase-functions/v2/firestore");

initializeApp();

exports.myUpdateFunc = 
    onDocumentUpdated('/myCollectionName/{myDocId}', (event) => {
        const old_doc = event.data.before.data();
        const new_doc = event.data.after.data();
        const id =  event.params.myDocId;

        // do something
    });

As mentioned in the documentation, Cloud functions gen 2 do not support Cloud Firestore triggers at the moment.

You'll have to use Gen 1 functions if your application rely on Firestore triggers.
