Support

Please file bugs in Issues Ask for help in #cordova on the Firebase Community Slack

Installation

See npm package for versions - https://www.npmjs.com/package/cordova-plugin-firebase-realtime-database

Install the by running:

cordova plugin add cordova-plugin-firebase-realtime-database --save

Download your Firebase configuration files, GoogleService-Info.plist for iOS and google-services.json for Android, and place them in the root folder of your Cordova project:

- My Project/
    platforms/
    plugins/
    www/
    config.xml
    google-services.json       <--
    GoogleService-Info.plist   <--
    ...

See https://support.google.com/firebase/answer/7015592 for details how to download the files from firebase.

This plugin uses a hook (after prepare) that copies the configuration files to the right place, namely platforms/ios/\<My Project>/Resources for iOS and platforms/android for Android.

Note that the Firebase SDK requires the configuration files to be present and valid, otherwise your app will crash on boot or Firebase features won't work.

Notes about PhoneGap Build

Hooks does not work with PhoneGap Build. This means you will have to manually make sure the configuration files are included. One way to do that is to make a private fork of this plugin and replace the placeholder config files (see src/ios and src/android) with your actual ones.

Notes about Android Build

You will have to manually add the following to platforms/android/build.gradle (around line 34:

buildscript {
    ...
    dependencies { 
        ...
        classpath 'com.google.gms:google-services:3.0.0'
    }
}
