fireseeder

Commandline tool for seeding data to Firestore

Features

• Supports all firestore data types including GeoPoint, Ref, etc.
• Supports firestore subcollections and nested subcollections
• Easily create complex seed data with random values
• Change seed data language
• Clear collections/subcollections before seeding
• Seed data merging

Getting Started

Install fireseeder using npm:

$ npm install fireseeder --save-dev

or yarn:

$ yarn add fireseeder -D

Then, download the Firebase Admin SDK json secret from the Firebase console, and place it somewhere in your project directory.

Create seeds directory in your project root (where your package.json is created), and add your config inside package.json:

"fireseeder": {
  "seedDir": "./seeds",
  "databaseUrl": "https://xxxxxx.firebaseio.com",
  "credential": "./path/to/credential.json"
},

Finally, create seed files inside ./seeds and run:

$ fireseeder seed

Configuration

Setting up project options

There are 3 ways to configure your project:

1. Use the CLI options
2. Use the fireseeder key in your package.json
3. Use environment variables

CLI usage

$ fireseeder seed [options]

Configuration using package.json

{
  "name": "fireseeder-example",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "seed": "fireseeder seed --fresh"
  },
  "fireseeder": {
    "databaseUrl": "https://xxxxxx.firebaseio.com",
    "credential": "./secret/credential.json",
    "lang": "en"
  }
}

NOTE:
The options in package.json should be in camelCase.
Also note that the CLI options takes precedence over the package.json config.

Using the environment variables

Environment variables should be prefixed with FSSEEDER_.

The options below are currently supported:

• FSSEEDER_SEED_DIR
• FSSEEDER_DATABASE_URL
• FSSEEDER_CREDENTIAL
• FSSEEDER_EMULATOR
• FSSEEDER_ID_KEY
• FSSEEDER_LANG

NOTE:
Environment variables takes precedence over the package.json config.

Configuration priority

1. CLI Options (Highest priority)
2. Environment variables
3. package.json config (Lowest priority)

Creating seed files

Example seed file

import { mapCollection, mapSubCollection, ref, geoPoint, name } from 'fireseeder'
 
export default mapCollection(10, (index) => ({
  _id: index + 1,
  firstName: name.firstName(),
  lastName: name.lastName(),
  ref: ref('/mod/1'),
  geopoint: geoPoint({ lat: 1, lng: 1 }),
  arr: ['a', 'b', 'c'],
  map: { a: 'b', c: 'd' },
  subCollection: mapSubCollection(4, () => ({ key: 'value' }))
}))

2. CLI Option
3. Environment variable FSSEEDER_ID_KEY
4. (Lowest priority) package.json config

NOTE: If the id is not specified in the seed data, a random ID will be created by firestore.
