NPM package for backup and restore Firebase Firestore
You can export and import data from firestore with sub collection.
Install using npm.
npm install firestore-export-import
You can Generate New Private Key from Project Settings from Firebase Console.
After that you need to copy the databaseURL for initiating the App.
You have to import this package in a JavaScript file and work from there.
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)))
If the sub collection exists, it will be saved under subCollection.
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));
})
This code will help you to import data from a JSON file to firestore. You have two options:
- Restore from a JSON file from your local machine
- Restore from a JSON from a HTTP request
This will return a Promise<{status: boolean, message: string}>
Remember that, this action doesn't remove the collection. It will override or add new data to the collection. If you want to remove the current collection, you should do it from firebase console or using firebase firestore:delete
firebase firestore:delete [options] <<path>>
// 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 and location fields are optional
firestoreService.restore('your-file-path.json', ['date1', 'date2.date3'], ['location1', 'location2']);
- Note that the date array only support two levels now. If you pass ['date1.date2.date3'], it won't work.
import request from 'request-promise';
...
const backupData = await request('JSON-URL');
const status = await firestoreService.restore(JSON.parse(backupData), ['date'], ['location']);
The JSON is formated as below. The collection name is test. first-key and second-key are document ids.
