“Use Node.js FOR SPEED” — @RoflscaleTips

I obeyed, therefore I wrote an opal NPM package.

Now I can trash Rails and opal-rails and start working on Node only!

server = Server.new 3000
server.start do
  [200, {'Content-Type' => 'text/plain'}, ["Hello World!n"]]
end

For it I had to write the Server class:

class Server
  def initialize port
    @http = `require('http')`
    @port = port
  end

  def start &block
    %x{
      this.http.createServer(function(req, res) {
        var rackResponse = (block.call(block._s, req, res));
        res.end(rackResponse[2].join(' '));
      }).listen(this.port);
    }
  end
end

Put them in app.opal and then start the server:

$ npm install -g opal      # <<< install the NPM package first!
$ opal-node app

YAY! now I can roflSCALE all of my RAils apps!!1
