Funky is a Ruby library to fetch data about videos posted on Facebook, such as their title, description, number of views, comments, shares, and likes.
How it works
Funky can get public Facebook video data whether the Graphi API requires insight permission or not. For example, even though the number of shares and views are shown publicly on the web page, the Graph API will not return those results unless the user has insight permission for that video. Using Funky, you can obtain the number of shares and views without insight permissions.
Under the hood, Funky hits Facebook's APIs on some cases, while other cases it will scrape Facebook's HTML to get the data. It's kind of... funky.
This is still a very early version, and it currently can only retrieve certain Facebook video data.
Installing and Configuring Funky
First, add funky to your Gemfile:
Funky will require an App ID and an App Secret which you can obtain after registering as a developer on Facebook for developers.
There are two ways to configure Funky with your App ID and App Secret:
By default, Funky will look for the environment variables called
FB_APP_SECRET. You can put those keys in your
.bash_profileand Funky will work.
export FB_APP_ID="YourAppID" export FB_APP_SECRET="YourAppSecret"
If you're using this in Rails, you can choose to create an initializer instead and configure the App ID and App Secret like so:
. do |config| config.app_id = 'YourAppID' config.app_secret = 'YourAppSecret' end
Or with environment variables (which is safer) like so:
. do |config| config.app_id = ENV['FB_APP_ID'] config.app_secret = ENV['FB_APP_SECRET'] end
Use #where clause to get an array of videos
ids = ['10154439119663508', '10153834590672139'] videos = ::.(id: ids) videos.first.id # => '10154439119663508' videos.first.created_time # => #<DateTime: 2015-12-17T06:29:48+00:00> videos.first.description # => "Hugh Jackman coaches Great Britain's..." videos.first.length # => 147.05 videos.first.picture # => "https://scontent.xx.fbcdn.net/v/..."
If a non-existing video ID is passed into the where clause, it is ignored. Other video IDs will still be retrieved.
ids = ['10154439119663508', '10153834590672139', 'doesnotexist'] videos = ::.(id: ids) videos.count # => 2 videos.first.id # => '10154439119663508' videos.last.id # => '10153834590672139'
Use #find to get a single video
video = ::.('10154439119663508') video.id # => '10154439119663508' video.like_count # => 1169 video.comment_count # => 65 video.share_count # => 348 video.view_count # => 10121
If a non-existing video ID is passed into #find, Funky::ContentNotFound will be raised.
::.('doesnotexist') # => raises Funky::ContentNotFound
Should there be a case where Funky is unable to connect to Facebook,
Funky::ConnectionError will be raised.
# Given funky is unable to establish a connection to Facebook ::.('10154439119663508') # => raises Funky::ConnectionError ::.(id: '10154439119663508') # => raises Funky::ConnectionError
After checking out the repo, run
bin/setup to install dependencies. Then, run
rake spec to run the tests. You can also run
bin/console for an interactive prompt that will allow you to experiment.
