This is a sample app showing use of the Facebook Graph API, written in Node.js, designed for deployment to Heroku.
Install dependencies:
npm bundle install
Create an app on Facebook and set the Website URL to http://localhost:5000/.
Copy the App ID and Secret from the Facebook app settings page into your .env:
echo FACEBOOK_APP_ID=12345 >> .env
echo FACEBOOK_SECRET=abcde >> .env
Launch the app with Foreman:
foreman start
The easiest way to deploy is to create an app on Facebook and click Cloud Services -> Get Started, then choose Node.js from the dropdown. You can then git clone the resulting app from Heroku.
If you prefer to deploy yourself, push this code to a new Heroku app on the Cedar stack, then copy the App ID and Secret into your config vars:
heroku create --stack cedar
git push heroku master
heroku config:add FACEBOOK_APP_ID=12345 FACEBOOK_SECRET=abcde
Enter the URL for your Heroku app into the Website URL section of the Facebook app settings page, hen you can visit your app on the web.
