Yt - a Ruby client for the YouTube API
Yt helps you write apps that need to interact with YouTube.
The source code is available on GitHub and the documentation on RubyDoc.
After registering your app, you can run commands like:
channel = Yt::Channel.new id: 'UCxO1tY8h1AhOz0T4ENwmpow'
channel.title #=> "Fullscreen"
channel.public? #=> true
channel.videos.count #=> 12
video = Yt::Video.new id: 'jNQXAC9IVRw'
video.title #=> "Fullscreen Creator Platform"
video.comment_count #=> 308
video.hd? #=> true
video.annotations.count #=> 1
video.comment_threads #=> #<Yt::Collections::CommentThreads ...>
# Use #take to limit the number of pages need to fetch from server
video.comment_threads.take(99).map(&:author_display_name) #=> ["Paul", "Tommy", ...]
The full documentation is available at rubydoc.info.
How to install
To install on your system, run
gem install yt
To use inside a bundled Ruby project, add this line to the Gemfile:
gem 'yt', '~> 0.32.0'
Since the gem follows Semantic Versioning,
indicating the full version in your Gemfile (~> major.minor.patch)
guarantees that your project won’t occur in any error when you bundle update
and a new version of Yt is released.

Instrumentation
Yt leverages Active Support Instrumentation to provide a hook which developers can use to be notified when HTTP requests to YouTube are made. This hook may be used to track the number of requests over time, monitor quota usage, provide an audit trail, or track how long a specific request takes to complete.
Subscribe to the request.yt
notification within your application:
ActiveSupport::Notifications.subscribe 'request.yt' do |*args|
event = ActiveSupport::Notifications::Event.new(*args)
event.payload[:request_uri] #=> #<URI::HTTPS URL:https://www.googleapis.com/youtube/v3/channels?id=UCxO1tY8h1AhOz0T4ENwmpow&part=snippet>
event.payload[:method] #=> :get
event.payload[:response] #=> #<Net::HTTPOK 200 OK readbody=true>
event.end #=> 2014-08-22 16:57:17 -0700
event.duration #=> 141.867 (ms)
end
Configuring your app
In order to use Yt you must register your app in the Google Developers Console.
If you don’t have a registered app, browse to the console and select "Create Project":
When your project is ready, select APIs & Auth in the menu and individually enable Google+, YouTube Analytics and YouTube Data API:
The next step is to create an API key. Depending on the nature of your app, you should pick one of the following strategies.
Apps that do not require user interactions
If you are building a read-only app that fetches public data from YouTube, then all you need is a Public API access.
Click on "Create new Key" in the Public API section and select "Server Key":
Once the key for server application is created, copy the API key and add it to your code with the following snippet of code (replacing with your own key):
Yt.configure do |config|
config.api_key = 'AIzaSyAO8dXpvZcaP2XSDFBD91H8yQ'
end
Remember: this kind of app is not allowed to perform any destructive operation, so you won’t be able to like a video, subscribe to a channel or delete a playlist from a specific account. You will only be able to retrieve read-only data.
Web apps that require user interactions
If you are building a web app that manages YouTube accounts, you need the owner of each account to authorize your app. There are three scenarios:
Scenario 1. If you already have the account’s access token, then you are ready to go. Just pass that access token to the account initializer, such as:
account = Yt::Account.new access_token: 'ya29.1.ABCDEFGHIJ'
account.email #=> (retrieves the account’s e-mail address)
account.videos #=> (lists a video to an account’s playlist)
Scenario 2. If you don’t have the account’s access token, but you have the refresh token, then it’s almost as easy. In the Google Developers Console, find the web application that was used to obtain the refresh token, copy the Client ID and Client secret and add them to you code with the following snippet of code (replacing with your own keys):
Yt.configure do |config|
config.client_id = '1234567890.apps.googleusercontent.com'
config.client_secret = '1234567890'
end
Then you can manage a YouTube account by passing the refresh token to the account initializer, such as:
account = Yt::Account.new refresh_token: '1/1234567890'
account.email #=> (retrieves the account’s e-mail address)
account.videos #=> (lists a video to an account’s playlist)
Scenario 3. If you don’t have any account’s token, then you can get one by having the user authorize your app through the Google OAuth page.
In the Google Developers Console, click on "Create new Client ID" in the OAuth section and select "Web application":
Fill the "Authorized Redirect URI" textarea with the URL of your app where you want to redirect users after they authorize their YouTube account.
Once the Client ID for web application is created, copy the Client ID and secret and add them to your code with the following snippet of code (replacing with your own keys):
Yt.configure do |config|
config.client_id = '49781862760-4t610gtk35462g.apps.googleusercontent.com'
config.client_secret = 'NtFHjZkJcwYZDfYVz9mp8skz9'
end
Finally, in your web app, add a link to the URL generated by running
Yt::Account.new(scopes: scopes, redirect_uri: redirect_uri).authentication_url
where redirect_uri
is the URL you entered in the form above, and scopes
is
the list of YouTube scopes you want the user to authorize. Depending on the
nature of your app, you can pick one or more among youtube
, youtube.readonly
userinfo.email
.
Every user who authorizes your app will be redirected to the redirect_uri
with an extra code
parameter that looks something like 4/Ja60jJ7_Kw0
.
Just pass the code to the following method to authenticate and initialize the account:
account = Yt::Account.new authorization_code: '4/Ja60jJ7_Kw0', redirect_uri: redirect_uri
account.email #=> (retrieves the account’s e-mail address)
account.videos #=> (lists a video to an account’s playlist)
Configuring with environment variables
As an alternative to the approach above, you can configure your app with variables. Setting the following environment variables:
export YT_CLIENT_ID="1234567890.apps.googleusercontent.com"
export YT_CLIENT_SECRET="1234567890"
export YT_API_KEY="123456789012345678901234567890"
is equivalent to configuring your app with the initializer:
Yt.configure do |config|
config.client_id = '1234567890.apps.googleusercontent.com'
config.client_secret = '1234567890'
config.api_key = '123456789012345678901234567890'
end
so use the approach that you prefer.
If a variable is set in both places, then Yt.configure
takes precedence.
How to test
To run tests:
rspec
We recommend RSpec >= 3.8.
Yt comes with two different sets of tests:
- Unit tests in
spec/models
,spec/collections
andspec/errors
- Legacy integration tests in
spec/requests
Coming soon will be a new set of high-level integration tests.
Integration tests are recorded with VCR. Some of the tests refer to fixture data that an arbitrary account may not have access to. If you need to modify one of these tests or re-record the cassette, we'd suggest working against your own version of the testing setup. Then in your pull request, we can help canonize your test/fixtures.
Some of the integration tests require authentication. These can be set with the following environment variables:
YT_TEST_CLIENT_ID
YT_TEST_CLIENT_SECRET
YT_TEST_API_KEY
YT_TEST_REFRESH_TOKEN
How to release new versions
If you are a manager of this project, remember to upgrade the Yt gem whenever a new feature is added or a bug gets fixed.
Make sure all the tests are passing on Travis CI, document the changes in CHANGELOG.md and README.md, bump the version, then run
rake release
Remember that the yt gem follows Semantic Versioning. Any new release that is fully backward-compatible should bump the patch version (0.0.x). Any new version that breaks compatibility should bump the minor version (0.x.0)
How to contribute
Yt needs your support! The goal of Yt is to provide a Ruby interface for all the methods exposed by the YouTube Data API (v3) and by the YouTube Analytics API.
If you find that a method is missing, fork the project, add the missing code, write the appropriate tests, then submit a pull request, and it will gladly be merged!
