Array DataType Should be Saved as an Array

node-firestore-import-export

Firestore data importing, exporting, and data clearing tool.

Export a Firestore database, including collections and documents, while keeping the structure intact.

{
  "__collections__": {
    "companies": {
      "docA": {
        "name": "Big Co",
        "employee_count": 2012,
        "created": {
          "__datatype__": "timestamp",
          "value": {
            "_seconds": 12343456,
            "_nanoseconds": 7890
          }
        },
        "location": {
          "__datatype__": "geopoint",
          "value": {
            "_latitude": -123.456789,
            "_longitude": 34.5678
          }
        },
        "AdministratorRef": {
          "__datatype__": "documentReference",
          "value": "path/to/the/document"
        },
        "__collections__": {
          "employees": ...,
          "products": ...
        }
      },
      "docB": ...,
      "docC": ...
    },
    "administrators": {
      "docA": ...,
      "docB": ...
    }
  }
}

where __collections__ holds the collections for a given document (or the root of the database).

Imports need to be from a file with the same structure (e.g. from an exported file).

Be careful! This can easily overwrite or mess up your data if you import to the wrong location.

Special Datatypes

Three types of data are serialized in the export:

Timestamps
Geopoints
DocumentReferences

They each are serialized in the following format:

{
  "__datatype__": "timestamp|geopoint|documentReference",
  "value": "The serialized value"
}

Installation

Install using npm.

npm install -g node-firestore-import-export

or yarn

yarn global add node-firestore-import-export

Alternatively download the source.

git clone https://github.com/jloosli/node-firestore-import-export.git

Retrieving Google Cloud Account Credentials

Visit the Firebase Console
Select your project
Navigate to Project Settings (at the time of writing the gear icon button at the top left of the page).
Navigate to Service Accounts
Click Generate New Private Key

This downloaded json file contains the proper credentials needed for node-firestore-import-export to authenticate.

Using Firebase Firestore Emulator

If using Firebase Emulators, all commands (Export, Import, and Clear) will override the account credentials setting if the FIRESTORE_EMULATOR_HOST environment variable is set.

Usage

Command Line

The path to the account credentials can either be passed with the -a/--accountCredentials flag, or placed in the GOOGLE_APPLICATION_CREDENTIALS environment variable. For example:

export GOOGLE_APPLICATION_CREDENTIALS=path/to/my/credentials.json
firestore-export -p

Export

-a, --accountCredentials <path> - path to Google Cloud account credentials JSON file. If missing, will look at the GOOGLE_APPLICATION_CREDENTIALS environment variable for the path.
-b, --backupFile <path>- Filename to store backup. (e.g. backups/full-backup.json). Defaults to firestore-export.json if missing.
-n, --nodePath <path>- Path to database node to start (e.g. collectionA/docB/collectionC). Backs up full database if empty or missing.
-p, --prettyPrint - JSON backups done with pretty-printing.

Examples

Export full database

firestore-export --accountCredentials path/to/credentials/file.json --backupFile /backups/myDatabase.json

Export with pretty printing

firestore-export --accountCredentials path/to/credentials/file.json --backupFile /backups/myDatabase.json --prettyPrint

Export from a specific path (and all its children/collections)

firestore-export --accountCredentials path/to/credentials/file.json --backupFile /backups/myDatabase.json --nodePath collectionA/document1/collectionCC

Import

-a, --accountCredentials <path> - path to Google Cloud account credentials JSON file. If missing, will look at the GOOGLE_APPLICATION_CREDENTIALS environment variable for the path.
-b, --backupFile <path>- Filename with backup data. (e.g. backups/full-backup.json).
-n, --nodePath <path>- Path to database node to start (e.g. collectionA/docB/collectionC).
-y, --yes - Unattended import without confirmation (like hitting "y" from the command line).

Examples

Import full database

firestore-import --accountCredentials path/to/credentials/file.json --backupFile /backups/myDatabase.json

Import to a specific path

firestore-import --accountCredentials path/to/credentials/file.json --backupFile /backups/myDatabase.json --nodePath collectionA/document1/collectionCC

Clear

-a, --accountCredentials <path> - path to Google Cloud account credentials JSON file. If missing, will look at the GOOGLE_APPLICATION_CREDENTIALS environment variable for the path.
-n, --nodePath <path>- Path to database node to start (e.g. collectionA/docB/collectionC).
-y, --yes - Unattended clear without confirmation (like hitting "y" from the command line). Command will wait 5 seconds so you can Ctrl-C to stop.
-w, --noWait - Combine this with the --yes confirmation to not wait 5 seconds

Example

Clear everything under a specific node

firestore-clear --accountCredentials path/to/credentials/file.json --yes

Library

The underlying library can be used in a node or web application for importing and exporting data in a similar fashion

Exporting

import {firestoreExport} from 'node-firestore-import-export';
import * as firebase from 'firebase-admin';

firebase.initializeApp({
    apiKey: "AIza....",                             
    authDomain: "YOUR_APP.firebaseapp.com",         
    databaseURL: "https://YOUR_APP.firebaseio.com", 
    storageBucket: "YOUR_APP.appspot.com",          
    messagingSenderId: "123456789"                  
});

const collectionRef = firebase.firestore().collection('collectionA/docB/collectionC');

firestoreExport(collectionRef)
    .then(data=>console.log(data));

Importing

import {firestoreImport} from 'node-firestore-import-export';
import * as firebase from 'firebase-admin';

firebase.initializeApp({
    apiKey: "AIza....",                             
    authDomain: "YOUR_APP.firebaseapp.com",         
    databaseURL: "https://YOUR_APP.firebaseio.com", 
    storageBucket: "YOUR_APP.appspot.com",          
    messagingSenderId: "123456789"                  
});

const data = {
  docA: {
    name: 'bob',
    __collections__: {}
  },
  docB: {
    name: 'jill',
    __collections__: {}
  }
};

const collectionRef = firebase.firestore().collection('collectionA/docB/collectionC');

firestoreImport(data, collectionRef)
    .then(()=>console.log('Data was imported.'));

Clearing

import {firestoreClear} from 'node-firestore-import-export';
import * as firebase from 'firebase-admin';

firebase.initializeApp({
    apiKey: "AIza....",                             
    authDomain: "YOUR_APP.firebaseapp.com",         
    databaseURL: "https://YOUR_APP.firebaseio.com", 
    storageBucket: "YOUR_APP.appspot.com",          
    messagingSenderId: "123456789"                  
});

const collectionRef = firebase.firestore().collection('collectionA/docB/collectionC');

firestoreClear(collectionRef)
    .then(()=>console.log('Everything under collectionA/docB/collectionC was removed.'));
