Rack::Authentication

A modular implementation of Rack::Auth

Installation

Add this line to your application's Gemfile:

gem 'rack-authentication'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rack-authentication

Usage

require "rack/authentication"
require "rack/authentication/adapters/basic"

class App < Sinatra::Base
  use Rack::Authentication do |config|
    config.realm "My App"
    config.adapter Rack::Authentication::Adapters::Basic
  end
end

Want to make your own custom authentication adapter?

Just inherit from Rack::Authentication::Adapters::Base. Three methods wil be defined for you:

type - The type of authentication (eg: Basic, Bearer)
env - The rack app's environment
credentials - The username/password of the request. This will always be an array

You're required to define good? and authorized?.

# my_adapter.rb
class MyAdapter < Rack::Authentication::Adapters::Base
  def good?
    "Basic" == type
  end

  def authorized?
    User.exists?(username: credentials[0], password: credentials[1])
  end
end

# app.rb
class App < Sinatra::Base
  use Rack::Authentication do |config|
    config.realm "My App"
    config.adapter MyAdapter
  end
end
