Cordova plugin for Google Firebase

cordova-plugin-firebase-realtime-database

Cordova plugin for Google Firebase Realtime Database Based on the the Firebase Notification / FCM plugin

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'
	}
}

Methods

ref

Get a reference to a child path:

var firebaseThings = window.FirebaseDatabasePlugin.ref('things');

this is the preferred way to use FirebaseDatabasePlugin

updateChildren

At a particular reference, update the given keys:

firebaseThings.updateChildren({
    'thing1' : 'aaa',
    'thing2' : 'bbb'
});

returns Promise

setValue

At a particular reference, set the given value:

firebaseThings.child('thing1').setValue('ccc');

returns Promise

setDatabasePersistent

Choose whether data should be persisted on disk, i.e. between app relaunches

window.FirebaseDatabasePlugin.setDatabasePersistent(true);

signInWithEmailAndPassword

Choose whether data should be persisted on disk, i.e. between app relaunches

window.FirebaseDatabasePlugin.signInWithEmailAndPassword(email, password);

returns Promise

cordova-plugin-firebase-realtime-database's Issues

Plugin with id 'com.google.gms.google-services' not found.

Hi,

I get this issue when building the app using cordova 6.4.0:

Script '/tmp/builds/4tmao7lheXDJrUXHXa/app/Plugins/cordova-plugin-firebase-realtime-database/src/android/build-extras.gradle' line: 11

• What went wrong:
  A problem occurred evaluating root project 'app'.
  Warning: > Plugin with id 'com.google.gms.google-services' not found.

how can read database

please Suggest me how can i read data real time
i want it so real
i can write in database using this demo but can't read

Calling setDatabasePersistent crashes the app

Using cordova 6.3.1 and testing on Android.

I was able to create an app with your plugin that updates values in firebase. However, once I added the
window.FirebaseDatabasePlugin.setDatabasePersistent(true); line to the code the app crashes hard and I don't know what the exception is. FYI - window.FirebaseDatabasePlugin.setDatabasePersistent(false); does the same thing.

I tried catching and and setting an error but nothing gets reported back to my app. With the following code the app doesn't crash but I don't see the error reported anywhere either:

            try{
                    FirebaseDatabase.getInstance().setPersistenceEnabled(persistent);
                } catch (Exception e) {                    
                    callbackContext.error(e.getMessage());
                }

Are there any special permission or other plugins needed to use this option?

Getting native database support merged upstream

Hi! We're very keen on using the native Firebase database support you implemented (notably the persistence piece)

We're curious why you haven't opened a merge request to get this included into the cordova-plugin-firebase plugin (the upstream of your fork) vs. maintaining this as its own separate plugin?

Thanks
