Twitch Authentication Documentation

Installation

Add this line to your application's Gemfile:

gem 'twitch_oauth2'

And then execute:

bundle install

Or install it yourself as:

gem install twitch_oauth2

Usage

Initialization

require 'twitch_oauth2'

client = TwitchOAuth2::Client.new(
  client_id: 'application_client_id',
  client_secret: 'application_client_secret',
  scopes: %w[user:read:email bits:read] # default is `nil`
  redirect_uri: 'application_redirect_uri' # default is `http://localhost`
)

Check tokens

tokens = previously_saved_tokens
# => { access_token: 'abcdef', refresh_token: 'ghikjl' }
# Can be empty.

client.check_tokens **tokens

The first run

You can pass nothing to #check_tokens, then client will generate new ones. You will be asked to open a Twitch link in a browser and login as user for whom tokens are intended.

Reusing tokens

Then, if you pass tokens, client will validate them and return themselves or refresh and return new ones.

Explicitly refresh tokens

You can refresh tokens manually:

client.refreshed_tokens refresh_token: 'ghikjl'

This is used internally in #check_tokens, and can be used separately for failed requests to API.

Development

After checking out the repo, run bundle install to install dependencies. Then, run bundle exec rake spec to run the tests.

We're using VCR cassettes with filtered sensitive data, so you don't need for real credentials (like Twitch Client ID and Client Secret) for changing existing methods, but you need for them to add new requests. You can read how to get them here.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
