FireStore Quick Start Guide

Base64 Encoded Private Key as Environment Variable

Encode -> const encoded = Buffer.from('username:password', 'utf8').toString('base64') Decode -> const plain = Buffer.from('dXNlcm5hbWU6cGFzc3dvcmQ=', 'base64').toString('utf8')

Using .env

// CAUTION: Remove in PROD if .env file is present
require('dotenv').config();

const projectId = process.env.GOOGLE_PROJECT_ID;
const email = process.env.GOOGLE_SERVICE_ACCOUNT_EMAIL;
// const key = process.env.GOOGLE_PRIVATE_KEY.replace(/\\n/g, '\n');
const key = Buffer.from(process.env.GOOGLE_PRIVATE_KEY_ENC, 'base64').toString('utf8') ; // decode from base64 encoded string

Firestore - Connect and Access Sample

// Based on : https://cloud.google.com/firestore/docs/create-database-server-client-library#node.js

const Firestore = require('@google-cloud/firestore');

const { Timestamp } = require('@google-cloud/firestore');
const db = new Firestore({
  projectId: projectId,
  credentials: {
    client_email: email,
    private_key: key,
  },
});

async function insertData() {
    const docRef = db.collection('users').doc('alovelace');
    await docRef.set({
        first: 'Ada',
        last: 'Lovelace',
        born: 1815
    });
        
    const aTuringRef = db.collection('users').doc('aturing');
    
    await aTuringRef.set({
        'first': 'Alan',
        'middle': 'Mathison',
        'last': 'Turing',
        'born': 1912
    });

    const data = {
      stringExample: 'Hello, World!',
      booleanExample: true,
      numberExample: 3.14159265,
      dateExample: Timestamp.fromDate(new Date('December 10, 1815')),
      arrayExample: [5, true, 'hello'],
      nullExample: null,
      objectExample: {
        a: 5,
        b: true
      }
    };
    
    const res = await db.collection('data').doc('one').set(data);
}
