Firestore data importing and exporting tool.
Export a Firestore database, including collections and documents, while keeping the structure intact.
Exports a json file with the following format:
{
"__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.
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"
}
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
- 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.
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
-a
,--accountCredentials
<path>
- path to Google Cloud account credentials JSON file. If missing, will look at theGOOGLE_APPLICATION_CREDENTIALS
environment variable for the path.-b
,--backupFile
<path>
- Filename to store backup. (e.g. backups/full-backup.json). Defaults tofirestore-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.
firestore-export --accountCredentials path/to/credentials/file.json --backupFile /backups/myDatabase.json
firestore-export --accountCredentials path/to/credentials/file.json --backupFile /backups/myDatabase.json --prettyPrint
firestore-export --accountCredentials path/to/credentials/file.json --backupFile /backups/myDatabase.json --nodePath collectionA/document1/collectionCC
-a
,--accountCredentials
<path>
- path to Google Cloud account credentials JSON file. If missing, will look at theGOOGLE_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).
firestore-import --accountCredentials path/to/credentials/file.json --backupFile /backups/myDatabase.json
firestore-import --accountCredentials path/to/credentials/file.json --backupFile /backups/myDatabase.json --nodePath collectionA/document1/collectionCC
The underlying library can be used in a node or web application for importing and exporting data in a similar fashion
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));
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.'));
