Using Facebook Graph Api in your Ionic 2 apps

Hi friends,

First of all, I would like to thank everyone who have been reading my blog regularly and checking for updates periodically. I am happy about the response I have been getting guys. In this post I will show you how to use Facebook Graph Api in Ionic 2 apps through a cordova plugin. Again this is a response post to several people who have been asking me about this.

Lets get started.

The code for this tutorial is available here.

A screencast video of this tutorial:


Now lets divide the tutorial into two segments. The first segment will deal with what you need to do in the facebook developer platform to get your app running. The second segment will deal with the actual ionic app that we will be writing.

First open the facebook developer portal by clicking here.

Then add a new app by clicking on the add new app from the dropdown on the top right corner as shown in the pic below.


Now in the modal that opens up choose your platform. (I will be choosing Android here as I am using an android phone).

In the next screen give the name of your app and click on the create new facebook App ID button.


In the subsequent dialog that opens choose App for pages as shown below and click on the Create App ID button as shown below.



In the next screen scroll down and fill the Package Name and default activity name in the Tell us about your Android application section as shown below and click next.


In the Prompt that appears click on the Use this package name button as shown below.


Now in the next section that appears we need to generate a key hash and paste it. To do so click on the show how to generate a development key hash link and follow the instructions. Once the key hash is generated copy and paste it here and click on next.

Now the setup is done. Scroll back up and click on the my apps button on the top right corner. You should see your app listed. Click on the app and you will see a dashboard screen. On the left hand side there will be a list of options. Click settings and a screen with all your app settings will be shown (as below).


(Make a note of the App ID).

Let’s start with our Ionic 2 app now.

Create a blank ionic app using the below command.

Then add the cordova-plugin-facebook4 as shown below

Get the App ID from the facebook dev portal and give it here.

After adding the plugin open up config.xml and change the widget id to the package name you gave previously as shown below.


Now let’s code our app. Our app will be a very simple one. We will have 3 buttons. One will be login button, a get details button and a logout button.

Open up home.html in the pages, home directory and insert the below code inbetween the <ion-content> tags.

Now open up the home.js file and insert the below code.

Let’s break this down.

  1. The login function helps in logging in to the user account (It would ask for permission when you login the first time).
  2. The getdetails() checks whether the user is logged in and if so, returns the id, name and gender of the user. This is where the Graph Api call is made. If the user is not logged in then it simply returns an alert with the message not logged in.
  3. Logout function is used to logout (Funny, I know. :)).

That’s it. Now run the app in an emulator or android device using the below command.

If everything’s fine you should now see an app using which you could connect to the Facebook platform.

Thanks for reading guys. All comments and suggestions are welcome. Peace.. :)

  • Do I need to make a separate facebook app for each platform? ie do one for ios and one for android?

    • Nope.. you could simple use the command ionic platform add android/ios while building your app. (Recently windows support has been made available too).

      • I meant during the Facebook App Set up, where you click Android.

        “Now in the modal that opens up choose your platform. (I will be choosing Android here as I am using an android phone).”

        Do i need to make one Facebook App with Android chosen, and one Facebook App with iOs chosen?
