facebook-service-provider
=========================

[](#facebook-service-provider)

It's a lightweight [Silex](http://silex.sensiolabs.org/) service to help creating Facebook applications.

Dependencies
------------

[](#dependencies)

It depends on two other providers:

- [Session](http://silex.sensiolabs.org/doc/providers/session.html)
- [URL Generator](http://silex.sensiolabs.org/doc/providers/url_generator.html)

It also uses the current request.

Configuration
-------------

[](#configuration)

It's done via the `fb.options` key. It's supposed to be an array with the following keys:

- `app_id`: your application's id
- `app_secret`: your application's secret token
- `permissions`: an array with the needed permissions
- `redirect_route`: name of the route which is responsible for handling new user authentications

Usage
-----

[](#usage)

The service sets the following session keys:

- `fb.access_token`: the access token you can use to make requests against the graph API
- `fb.page_liked`: whether the current page is liked or not

A `before()` middleware is registered to be run before yours. It handles two cases:

- it's a post request and we have a `signed_request` parameter: decoding is done automatically and set among the post values with the `fb.data` key
- it's a request for the aforementioned redirect route, and we have a `code` query parameter: fetching a token, then the user details is done automatically, set among the post values with the `fb.data` key

In both cases the event `fb.user_info` is dispatched, with the user data as the subject.

Events
------

[](#events)

- `fb.user_info` when getting user data from facebook
- `fb.like` when the user just liked the page
- `fb.unlike` when the user just unliked the page

Samples
-------

A sample application-level `before` middleware to log a user in automatically:
