ngOpenFB

ngOpenFB is an angular module that lets you integrate your JavaScript application with Facebook. Original idea is from the OpenFB library by Christophe Coenraets rewritten for a better usage with Ionic and with Promise support.

ngOpenFB works for both browser-based angular apps and ionic apps. There is no dependency on the Facebook SDK!

Getting Started

1. Install ngOpenFB

bower install ngOpenFB

2. Install the InAppBrowser plugin by cordova

cordova plugin add cordova-plugin-inappbrowser

3. Include ngOpenFb to your angular/ionic app

angular.module('<YOUR_APP>', ['ngOpenFB'])

4. Inject the $openFB service in your module
5. Call the $openFB.init() function and set your Facebook App Id

$openFB.init( {appId: '<YOUR_APP_ID>'} );

6. Copy the oauthcallback.html to your project

    // not logged in
});

Login using Facebook:

$openFB.login({scope: 'email,user_friends'})
.then(function( token ) {
    // log in successful
    // send token to your server
}, function( err ) {
    // error logging in
});

======

Fetch user's profile and profile picture:

var me = {};
$openFB.api({path: '/me'})
.then(function( res ) {
    angular.extend(me, res);
, function( err ) {
    // error
});

$openFB.api({
    path: '/me/picture',
    params: {
        redirect: false,
        height: 64,
        width: 64
    }
}).then(function( res ) {

Post on the user's feed:

$openFB.api({

Using a different url for your login callback:

$openFB.init({
    appId : '<YOUR_APP_ID>'
    browserOauthCallback : <PATH_TO_YOUR_HOST> + '/oauthcallback.html'
    cordovaOauthCallback : <PATH_TO_YOUR_OTHER_HOST> + '/login_success.html'
