Facebook development in localhost

facebook, localhost

Solution

Edit: 2-15-2012 This is how to use FB authentication for a localhost website.

I find it more scalable and convenient to set up a second Facebook app. If I'm building MyApp, then I'll make a second one called MyApp-dev.

- Create a new app at https://developers.facebook.com/apps

- (New 2/15/2012) Click the `Website` checkbox under 'Select how your application integrates with Facebook' (In the recent Facebook version you can find this under Settings > Basic > Add Platform - Then select website)

- Set the Site URL field (NOT the App Domains field) to http://www.localhost:3000 (this address is for Ruby on Rails, change as needed)

- In your application initializer, put in code to detect the environment

- Sample Rails 3 code

if Rails.env == 'development' || Rails.env == 'test'
  Rails.application.config.middleware.use OmniAuth::Builder do
    provider :facebook, 'DEV_APP_ID', 'DEV_APP_SECRET'
  end
else
  # Production
  Rails.application.config.middleware.use OmniAuth::Builder do
    provider :facebook, 'PRODUCTION_APP_ID', 'PRODUCTION_APP_SECRET'
  end
end

I prefer this method because once it's set up, coworkers and other machines don't have additional setup.
