How to access firestore.Timestamp from Firebase Cloud Function

Question

We are in the middle of converting our Firestore Date object to the new Timestamp Objects

We have done so successfully on the front end by importing firestore

Answer 1

At this very moment in time, Timestamp is simply not available in the latest version of the @google-cloud/firestore npm module for node. You can also see that it's not included in the API docs. Perhaps it will be added in the next release of @google-cloud/firestore.

Answer 2

This worked for me from node:

firebase = require('firebase')
firebase.firestore.Timestamp

Answer 3

Since you need it inside a cloud function, then you are working with triggers (onCreate, onUpdate...etc) which carries the timestamp via snap parameter. you can use it as below. (it worked with me)

exports.newUserCreated = functions.firestore.document('users/{userId}').onCreate(async (snap, context) => {
firestore.collection(`users/${userID}/lists`).add({
    'created_time': snap.updateTime,
    'name':'new list name',
}).then(documentReference => {
    console.log("list created");
    return null;
  }).catch(error => {
    console.error('Error creating list', error);
    process.exit(1);
});

});

Answer 4

I came across the same problem and so created a basic node module for Firebase Firestore Timestamps here https://www.npmjs.com/package/firebase-firestore-timestamp

Basic code port from https://www.gstatic.com/firebasejs/4.13.0/firebase-firestore.js

Answer 5

With the release of V2.0 of Firebase Functions is looks like they've added Timestamp support in the Firebase Admin SDK package.

Have a look at the official docs here.

import { firestore } from 'firebase-admin';
...
const now = firestore.Timestamp.now()
