TwitchRB

TwitchRB is the easiest and most complete Ruby library for the Twitch Helix API.

Installation

Add this line to your application's Gemfile:

gem "twitchrb"

Usage

Set Client Details

Firstly you'll need to set a Client ID and an Access Token.

An access token is required because the Helix API requires authentication.

@client = Twitch::Client.new(client_id: "abc123", access_token: "xyz123")

Resources

The gem maps as closely as we can to the Twitch API so you can easily convert API examples to gem code.

Responses are created as objects like Twitch::Channel. Having types like Twitch::User is handy for understanding what type of object you're working with. They're built using OpenStruct so you can easily access data in a Ruby-ish way.

Pagination

Some of the endpoints return pages of results. The result object will have a data key to access the results, as well as metadata like cursor for retrieving the next and previous pages. This can be used by using before and after parameters, on API endpoints that support it.

An example of using collections, including pagination:

results = @client.clips.list(broadcaster_id: 123)
#=> Twitch::Collection

results.total
#=> 30

results.data
#=> [#<Twitch::Clip>, #<Twitch::Clip>]

results.each do |result|
  puts result.id
end

results.first
#=> #<Twitch::Clip>

results.last
#=> #<Twitch::Clip>

results.cursor
#=> "abc123"

# Retrieve the next page
@client.clips.list(broadcaster_id: 123, after: results.cursor)
#=> Twitch::Collection

OAuth

This library includes the ability to create, refresh and revoke OAuth tokens.

# Firstly, set the client details
@oauth = Twitch::OAuth.new(client_id: "", client_secret: "")

# Create a Token
# grant_type can be either "authorization_code" or "client_credentials"
# scope is a space-delimited list of scopes. This is optional depending on the grant_type
@oauth.create(grant_type: "", scope: "")

# Refresh a Token
@oauth.refresh(refresh_token: "")

# Device Code Grant Flow
# scopes is required and is a space-delimited list of scopes
# https://dev.twitch.tv/docs/authentication/getting-tokens-oauth/#device-code-grant-flow
@oauth.device(scopes: "bits:read channel:read:subscriptions")

# Validate an Access Token
# Returns false if the token is invalid
@oauth.validate(token: "")

# Revoke a Token
@oauth.revoke(token: "")
