'How to add Timestamp in firebase cloud functions
I am trying to add Timestamp in Firestore document on Firebase Cloud functions.
I had tried firestore.Timestamp.fromDate(new Date()), but its not working.
const functions = require('firebase-functions');
const admin = require('firebase-admin');
const firestore = admin.firestore();
const createdAt = firestore.Timestamp.fromDate(new Date());
console.log(createdAt);
Value of createdAt should return the server timestamp, but its throwing error.
Solution 1:[1]
This line of code has a syntax error in it. It's not valid JavaScript:
const createdAt: firestore.Timestamp.fromDate(new Date());
It looks like you meant to write this:
const createdAt = firestore.Timestamp.fromDate(new Date());
Solution 2:[2]
I personallly used const timestamp = new Date().getTime();
then saved it to the firstore document and it worked.
Solution 3:[3]
When using cloud function hooks specifically functions.auth.user().onCreate((user) => {}) I use the user.metadata.creationTime to get the exact creation time without having to go into timezone and date/time issues.
