Sinatra Single User Simple Auth Extension

Sinatra extension with methods and routes for dealing with simple, single user authorization (username and password)

Background

This extension is based on the awesome sinatra-simple-auth gem by Vasily Polovnyov. I wanted the exact same functionality but I also wanted to be able to specify a username/email as well so I can do some custom atlassian crowd authentication. I thought someone else may find having a username handy as well so here it is. Massive thanks to Vasily as 99.9% of this plugin is his work - I just added the username field.

Installation

gem install sinatra-single-user-auth

Or via bundler:

gem 'sinatra-single-user-auth'

Usage (classic style applications)

You just need to make sure you pass the params username and password from the login form

# classic_app.rb
require 'rubygems'
require 'sinatra'
require 'sinatra/simple_auth'

enable :sessions
set :username, 'my_username' # set the username
set :password, 'my_cool_password' # set the password
set :home, '/secure/' # where user should be redirected after successful authentication

get '/login/?' do
  erb :login # page with auth form
end

get '/secure/' do
  protected! # protected route, requires auth
  erb :secure
end

get '/' do
  if authorized? # helper method
    "Hello, #{app.username}"
  else
    "Not authorized"
  end
end

Usage (modular style applications)

# modular_app.rb
require 'sinatra/base'
require 'sinatra/simple_auth'

class SinatraModularApp < Sinatra::Base
  enable :sessions
  register Sinatra::SimpleAuth

  set :username, 'my_username' # set the username
  set :password, 'my_password' # set the password
  set :home, '/' # where user should be redirected after successful authentication

  get '/login/?' do
    erb :login # page with auth form
  end

  get '/secure/' do
    protected! # protected route, requires auth
    erb :secure
  end

  get '/' do
    if authorized? # helper method
      "Hello, #{app.username}"
    else
      "Not authorized"
    end
  end
end
