Facebook Platform - Tech
- 1. Building Applications on Facebook Platform David Zhuang Entrepreneur’s Playfield
- 2. Overview Open Distribution to Millions of Users Capabilities / Integration Points Architecture Components Resources
- 3. Open Distribution Build It, And They Are Already There Developers: Equal Footing with Organizations Platform Is Completely Open Automated Viral Distribution Engine: News Feed New Model for Entrepreneurs Experiment: Low Investment (Time/Money) If It Works, Ramp up
- 4. Capabilities / Integration Points Product Directory About Left Nav Facebook Canvas Pages Home User Dashboard Settings Profile Profile Box Profile Action Links Privacy Settings News Feed Alerts Message Attachments Requests
- 5. Canvas: Embedded Application Left Nav Canvas
- 6. Home Page: Viral Distribution Left Nav News Feed
- 7. Profile: Viral Distribution Left Nav News Feed Profile Box
- 8. Architecture: Traditional Web App Web/App Server Database 1. HTTP Request 2. HTML Response SQL Query Data Your Server
- 9. Architecture: Facebook App - Canvas Web/App Server Database 1. HTTP 6. HTML SQL Query Data Your Server Facebook Server 2. HTTP / REST 3. API / FQL 4. API Rsp 5. FBML
- 10. Architecture: Facebook App - Profile 0. API / FBML (Pushed Separately) Web/App Server Database 1. HTTP 2. HTML SQL Query Data Your Server Facebook Server
- 11. Components API Web Service API Client Library: Official: PHP, Java Unofficial: Perl, Python, Ruby, VB.NET, and others FQL Similar to SQL Access to user profile, friend, group, event, and photo FBML Similar to HTML Subset of HTML + Proprietary Extensions
- 12. API Web Service API: Well Documented API Client Library Mostly Covered by Web Service API Documentation For the Rest, Read Code (Only 2 Files) facebook.php facebookapi_php5_restlib.php Access Facebook User Data Profile, Friends, Group, Event, Photo, etc. Update User Views Profile, Feed, etc.
- 13. API Client Lib Function Examples $facebook->redirect($url) $facebook->require_login() / $facebook->require_add() $facebook->get_login_url() / $facebook->get_add_url() $facebook->api_client->feed_publishStoryToUser($title, $body, ...) $facebook->api_client->friends_get() $facebook->api_client->friends_getAppUsers() $facebook->api_client->groups_get ($uid=null, $gids=null) $facebook->api_client->profile_setFBML($markup, $uid=null)
- 14. FQL Very Similar to SQL Select From One Table At a Time, No Join Query Must Be Indexable Access Facebook Database Tables user, friend, group, group_member, event, event_member, photo, album, photo_tag
- 15. FBML A Subset of HTML Excluded: <script> Limited: <style> (internal CSS only) Cached: <img> Hidden Fields Added (For Security): <form> Proprietary Extensions Markup Tags: UI Elements Procedural Tags: Control Program Flow Mock Ajax
- 16. FBML Tags Example: Markup Tags Code: <fb:dashboard> < fb:action href="new.php">Create a new photo album </fb:action> < fb:action href="you.php">Photos of You </fb:action> </fb:dashboard> Preview:
- 17. FBML Tags Example: Procedural Tags Code: < fb:if-can-see uid="12345" what="profile"> You're allowed to see 12345's profile, chum! <fb:else> No profile for you! </fb:else> </fb:if-can-see>
