On the 20th floor of a San Francisco skyscraper, a handful of developers are working on a new technology that's changing the way real-time web apps are built and how they scale. This technology, called Node.js, is being hailed as "the new Ruby on Rails" by some in the developer community. But it's not a magic bullet, nor is it appropriate for all programming scenarios. Joyent, an SF-based cloud software company, is sponsoring the growth and development of Node. In the process, we learned a lot about how and why Node works for the real-time web — and how Node is changing the way the developer community creates the Internet as we know it.
What Makes Node Different Node had a watershed year in 2010, and it's shaping up to be as popular as Ruby on Rails among developers. Then there's the community. Node's Explosive Growth Node for Real-Time Voice. How To Node - NodeJS. Erlang vs node.js. I've written about Erlang in the past, and my suspicion that, soon or later, other languages/systems will come along and "eat its lunch".
Scala is one such potential contender. Another that has been gaining some visiblity lately is node.js, a simple framework for creating networked applications on top of Google's V8 Javascript engine. I should define what Erlang's lunch is a little bit better before we go on. Erlang does several things really, really well; better than many existing, mainstream systems: Concurrency – the Actor model that it uses is much easier and more pleasant than dealing with threads. Of these, I think the big one is concurrency. How does Erlang do "concurrency"?

Not excited by hello world in node.js? No problem. Let's say you are a startup focusing on upload technology and you want the maximum level of control for your file uploads. In our case that means having the ability to directly interact with the multipart data stream as it comes in (so we can abort the upload if something isn't right, - beats the hell out of letting the user wait an hour to tell him after the upload has finished). Here is a complete example on how to accomplish this in node.js (you'll need the bleeding edge git version): var http = require('http');var multipart = require('multipart');var sys = require('sys'); function upload_file(req, res) { req.setBodyEncoding('binary'); sys.print("Uploading "+mb+"mb ("+progress+"%)\015"); The code is rather straight forward.
Next we create a server listening on port 8000 that dispatches incoming requests to one of our 3 functions: display_form, upload_file or show_404.
