Makes it easy to upgrade any request to a websocket connection.
SinatraWebsocket is a fork of Skinny merged with Rack WebSocket. It provides helpers methods to detect if a request is a WebSocket request and defer to an EM::WebSocket::Connection.
require 'sinatra'
require 'sinatra-websocket'
set :server, 'thin'
set :sockets, []
get '/' do
if !request.websocket?
erb :index
else
request.websocket do |ws|
ws.onopen do
ws.send("Hello World!")
settings.sockets << ws
end
ws.onmessage do |msg|
EM.next_tick { settings.sockets.each{|s| s.send(msg) } }
end
ws.onclose do
warn("websocket closed")
settings.sockets.delete(ws)
end
end
end
end
