firestore-export-import

NPM package for backup and restore Firebase Firestore

Installation

npm install firestore-export-import

Get Google Cloud Account Credentials from Firebase

You can Generate New Private Key from Project Settings from Firebase Console.

After that you need to copy the databaseURL for initiating the App.

Usage

You have to import this package in a JavaScript file and work from there.

Export data from firestore

You can export collection and sub collection from your data. The sub collection is optional.

// In your index.js 

const firestoreService = require('firestore-export-import');
const serviceAccount = require('./serviceAccountKey.json');

// Initiate Firebase App
firestoreService.initializeApp(serviceAccount, databaseURL);

// Start exporting your data
firestoreService
  .backup('collection-name', 'sub-collection-optional')
  .then(data => console.log(JSON.stringify(data)))

Get all collections data

This is a suggestion from jcummings2 and leningsv

The ['collectionName1', 'collectionName2'] is OPTIONAL, you can remove this parameter to get all of the current collections in your firestore.

The result is an object of collection's data.

firestoreService
  .backups(['collectionName1', 'collectionName2']) // Array of collection's name is OPTIONAL 
  .then(collections => {
    // You can do whatever you want with collections
    console.log(JSON.stringify(collections));
  })

Import data to firestore

This code will help you to import data from a JSON file to firestore

// In your index.js 

const firestoreService = require('firestore-export-import');
const serviceAccount = require('./serviceAccountKey.json');

// Initiate Firebase App
firestoreService.initializeApp(serviceAccount, databaseURL);

// Start importing your data
// The array of date fields is optional
firestoreService.restore('your-file-path.json', ['date1-field', 'date2-field']);

The JSON is formated as below. The collection name is test. first-key and second-key are document ids.

{
  "test" : {
    "first-key" : {
      "email"   : "[e-mail]",
      "website" : "dalenguyen.me",
      "custom"  : {
        "firstName" : "Dale",
        "lastName"  : "Nguyen"
      },
      "date": {
        "_seconds":1534046400,
        "_nanoseconds":0
      }
    },
    "second-key" : {
      "email"   : "[e-mail]",
      "website" : "google.com",
      "custom"  : {
        "firstName" : "Harry",
        "lastName"  : "Potter"
      },
