metisoft-go-firebase-util

This module provides an abstraction over the firebase.google.com/go module to better suit Metisoft server applications written in Go.

Installation

1. In your Go application, add firebaseUtil "github.com/MetisoftSolutions/metisoft-go-firebase-util" to your imports list.
2. Make a call to godep get, or whatever other dependency manager you use to retrieve the metisoft-go-firebase-util module.
3. In your server's initialization code, make a call to firebaseUtil.Init(), which requires at least PathToServiceAccountKey and DatabaseUrl to be set in the options argument.

PathToServiceAccountKey should be the full path to the serviceAccountKey.json file that you should get from the Firebase Console. You can get this key from Project Settings -> Service Accounts -> Firebase Admin SDK -> Generate New Private Key.

DatabaseUrl is the URL to the Firebase database for your app. This can also be found on the Firebase Admin SDK page.

Usage

Push notifications

You can send push notifications using firebaseUtil.SendPushNotification(). The first argument is some form of user ID. By default, this is a Firebase token. However, if you supply a function to the configuration options object's FnGetFirebaseTokenForUser key in the Init() call, then you can pass in a user ID native to your user authentication system. This relies on you defining your FnGetFirebaseTokenForUser function to return a Firebase token when given a user ID.
