So far, we don’t have an official and free way to import or export our data in/to firebase firestore. Of course we don’t want to any unwanted accident happen, where we lose all of our data without backup.
Luckily, Dalenguyen made a node package to import and export firestore for us.
1. Download serviceaccount.json from Firebase Console > Project Setting > Service Accounts
2. Clone the previous repo ” git clone https://github.com/dalenguyen/firestore-import-export.git ”
3. Download requirements with “npm install”
4. For export
node export.js <your-collection-name> <sub-collection-name-(optional)>
5. For Import
node import.js import-to-firestore.json date=date geo=Location
Warning for import: It will overwrite your current collection if there is a collection with that name in your Firestore.
