Webrick::Websocket

This gem allows you to use Websocket in your WEBrick web application. First, create a HTTPServer with websocket support:

require 'webrick/websocket'
server = WEBrick::Websocket::HTTPServer.new(Port: 8080, DocumentRoot: File.dirname(__FILE))

having that done do anything you would do with a regular WEBrick instance. However, you can mount a Websocket Servlet.

class MyServlet < WEBrick::Websocket::Servlet
  def select_protocol(available)
    # method optional, if missing, it will always select first protocol.
    # Will only be called if client actually requests a protocol
    available.include?('myprotocol') ? 'myprotocol' : nil
  end
  
  def socket_open(sock)
    # optional
    sock.puts 'Welcome' # send a text frame
  end
  
  def socket_close(sock)
    puts 'Poof. Socket gone.'
  end
  
  def socket_text(sock, text)
    puts "Client sent '#{text}'"
  end
end

server.mount('/websocket', MyServlet)

Aaaaand lets start the server

server.start

Note, that it will always use the same servlet instance for a single socket and that each socket has its own servlet instance. This means you can safely use instance variables inside the servlet to store the sockets state

Add this line to your application's Gemfile:

gem 'webrick-websocket'

And then execute:

$ bundle

Or install it yourself as:

$ gem install webrick-websocket
