Node 0.10.1

Node 0.10.1 has been released, hot on the heels of 0.10.0. This version improves the performance of the non-streaming crypto APIs, fixes some tls and net module issues, and makes missing callbacks in streams2 show a warning rather than raising an exception.

Express Group Handlers

Express Group Handlers (GitHub: tldrio / express-group-handlers, License: MIT, npm: express-group-handlers) by Louis Chatriot provides a little bit of sugar for managing Express middleware. It allows routes to be wrapped with beforeEach and afterEach so middleware can be confined to certain routes.

The beforeEach method can accept multiple middlewares to run, and it's easy to wrap it around existing code:

var groupHandlers = require('express-group-handlers');


app.beforeEach(groupHandler, function(app) {
  app.get('/route3', finalHandler3); // GET /route3 will execute groupHandler, then finalHandler3


Fox (GitHub: azer / fox, License: BSD, npm: fox) by Azer Ko├žulu is a test framework that is largely compatible with Mocha, as long as you don't have nested invocations of describe. It works with both Node and client-side projects, and injects chai so you automatically get assertions without having to load an extra library.

Passing the -b flag to the command-line program will cause Fox to compile the scripts necessary to run the tests in a browser. It also includes tests written with itself, of course!


iWebPP.io (GitHub: InstantWebP2P / iwebpp.io, License: MIT, npm: iwebpp.io) by Tom Zhou is a set of projects designed to send HTTP over UDP, the goal being to take advantage of UDP's inherent performance benefits. It supports TURN and STUN channeling with WebSockets, for realtime streaming.

It can run web services using peer-to-peer protocols, behind NAT and firewalls. The iwebpp.io module includes a binary called node-httpp, which provides the HTTP over UDP handling. The project includes installation instructions, and a brief roadmap.

I've seen a few peer-to-peer Node projects, but I think this is the first one I've seen that uses UDP as the transport layer protocol. It's also interesting that the author is directly addressing NAT issues.
