How to access firestore.Timestamp from Firebase Cl

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

import { firestore } from 'firebase';

and then replacing all Date object types with firestore.Timestamp

  startDate: firestore.Timestamp;

The problem is I can't seem to find a way to get access to Timestamp in node.

I have tried logging both the admin and functions object but cant seem to find Timestamp at all

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
...
console.log(functions)
console.log(admin)

These are what I've tried and they have all returned with 'Timestamp does not exist on undefined'

import * as firebase from 'firebase';
...
firebase.firestore.Timestamp.now()

---

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

---

import * as admin from 'firebase-admin';
...
admin.firestore.Timestamp.now()

---

Here are my package.json dependancies

    "@sendgrid/mail": "^6.2.1",

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.

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

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()
