Quokka provides tools to make logging in with Facebook from your server a breeze.
Add this line to your application's Gemfile:
gem 'quokka'And then execute:
$ bundle
Or install it yourself as:
$ gem install quokka
The Facebook login flow has a couple of steps that Quokka can help you out with.
First you need to setup your app id and secret by specifying them in the env variables FACEBOOK_APP_ID and FACEBOOK_SECRET.
Next your web application will need to redirect to a dialog url created by:
Quokka.login_dialog_url(redirect_uri)
Facebook will redirect to your redirect uri with a code parameter. Pass this to access_token to get the required token.
access_token = Quokka.access_token(redirect_uri, code)
Now you can use the access_token you received to get user data from Facebook.
Quokka.user_data(access_token)
