Firebase-import is a helper utility for importing large JSON files into your Firebase database. It breaks the JSON into smaller chunks and uploads them individually through the Firebase API.
To import files bigger than 250MB, use Firebase Streaming Import.
Install the firebase-import module globally:
$ npm install -g firebase-import
or install it locally and add it to your path:
$ npm install firebase-import
$ export PATH=$PATH:`npm bin`
$ firebase-import
Usage: firebase-import
Options:
--firebase_url, -f Firebase database URL (e.g. https://test.firebaseio.com/dest/path). [required]
--json, -j The JSON file to import. [required]
--merge, -m Write the top-level children without overwriting the whole parent. [boolean]
--force Don't prompt before overwriting data. [boolean]
--auth, -a Specify an auth token to use (e.g. your Firebase Secret).
$ firebase-import --firebase_url https://test.firebaseio-demo.com --json test.json

Import completed.
Or an example of merging the contents of test.json with what's already in Firebase:
$ firebase-import --firebase_url https://test.firebaseio-demo.com --json test.json --merge
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.
