Firebase-Import

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.

Installing

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`

Usage

$ firebase-import

  --json, -j          The JSON file to import.                                            [required]
  --merge, -m         Write the top-level children without overwriting the whole parent.  [boolean]
