Facebook development in localhost

Just wanted to know if there is any way I could develop Facebook applications in localhost.

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.

Of course you can, just add the url localhost (without "http") in your app_domain and then add in your site_url http://localhost (with http)

Update

Facebook change the things a little now, just go to the app settings and in the site url just add http: //localhost and leave the App Domain empty

Here is my config and it works fine for PHP API:

app domain

   http://localhost

Site URL

   http://localhost:8082/
