Node Roundup: express-soap2json, cb, ApiServer

express-soap2json

SOAP might not be the most exciting technology to work with, but if you like Node and Express then express-soap2json (License: MIT, npm: express-soap2json) by Tony Sokhon can make it a little bit easier to work with.

By wrapping around a SOAP service, express-soap2json creates a JSON/HTTP proxy. It's built using the soap module by Vinay Pulim. Tony has included some Mocha tests, and the README has some basic documentation.

An Alternative to Node's console.time

In A Powerful Alternative to Node's console.time(), Dmitri Melikyan discusses using his Nodetime profiler in place of console.time and console.timeEnd.

What if you want to know more about what happens in-between, say CPU time or other nested network of file operations in microsecods precision?

cb

cb (License: MIT, npm: cb) by Jeremy Martin is yet another control flow library. Or is it?

Not exactly. There are literally hundreds of libraries available for easing some of the pains associated with the continuation passing style, and most of them do a pretty good job at this.

Rather than compete with these libraries, cb() focuses on a much narrower range of problems, and is intended to be complementary to your control flow library (or lack thereof) of choice.

It features timeout and error handling with a chainable API, so the following is possible:

var cb = require('cb')  
  , fs = require('fs');

fs.readFile(  
  '/usr/share/dict/words'
, 'utf8'
, cb(console.log)
    .error(console.error)
    .timeout(50)
    .once()
);

ApiServer

ApiServer (GitHub: kilianc / node-apiserver, License: MIT, npm: apiserver) by Kilian Ciuffolo is a modular framework that's a bit like Restify, but can also be used to make Express-style web applications. Kilian has written his own comparisons with Express and Restify, and it's compatible with Express middleware even though it's not built with Connect.

The routing module, apiserver-router, features a caching system, and applications are built using objects. These objects are known as modules, and each method is an API endpoint. It works with plain objects and prototype classes -- classes are ideal if the module has a state (Kilian's example passes in a database reference).

The author has also included a Mocha test suite, and the documentation is pretty solid too.
