So how do you write a basic web server in CoffeeScript?

The Node.js "Hello World" web server:

    http = require 'http'

    server = http.createServer (req, res) ->
      res.writeHeader 200, 'Content-Type': 'text/plain'
      res.write 'Hello, World!'
      res.end()

    server.listen 3000

    console.log "Server running at http://localhost:3000/"

I'm obligated to respond with the same server in Twisted:

    from twisted.internet import reactor
    from twisted.web import resource, server

    class HelloWorldResource(resource.Resource):
        isLeaf = True
        def render_GET(self, request):
            return "Hello, World!"

    reactor.listenTCP(3000, server.Site(HelloWorldResource()))
    reactor.run()

OT question. How healthy is the Twisted ecosystem these days? Besides it being stable and been around for years, how does the post-divmod horizon looking? Is the whole stack still being maintained?

All of the old Divmod team are still hacking Twisted. It's still maintained, everything gets taken care of, and there's really no doubt about Twisted's future.

Well but this isn't written in CoffeeScript. This is what I was saying: CoffeeScript can work alongside Node.js but can't access the filesystem. It might be good in its own right for DOM scripting and such but it doesn't open any more doors than Javascript.

Then what is it written in, if not CoffeeScript. You're somehow very very confused about things :-)

No I think you are confused. That is Node.js syntax. Ok now show me how you open a file on the filesystem in CoffeeScript then.

> CoffeeScript can work alongside Node.js but can't access the filesystem.

Um. Node.js gives you access to the filesystem... http://nodejs.org/docs/latest/api/fs.html

And anything you can do in Node, you can do from CoffeeScript code running under Node.

Quite a lot of examples of CoffeeScript with Node.js here: https://gist.github.com/978411
