Firebase-import is a helper utility for importing large JSON files into your Firebase Realtime Database. It breaks the JSON into smaller chunks and uploads them individually through the Firebase API.

This utility is designed and tested for imports of files up to 400MB.

Import completed.

Or an example of merging the contents of test.json with what's already in Firebase:

$ firebase-import --database_url https://test.firebaseio-demo.com --path / --json test.json --merge --service_account /path/to/your/service_account.json
Each top-level child in test.json will be written under https://test.firebaseio-demo.com/.
If a child already exists, it will be overwritten.
Press <enter> to proceed, Ctrl-C to abort.
