Node 0.6.4

Node 0.6.4 has been released. One interesting thing I noticed was this:

sys: deprecate module some more, print stack trace if NODE_DEBUG=sys

It can be a little bit frustrating when working with dependencies that
still use this module, so at least these stack traces will make it
easier to find out who to blame.

Node Web Development

Node Web Development
(Price: \$22.49, Ebook: \$12.74, Publisher: Packt) by David Herron assumes rudimentary JavaScript knowledge and introduces Node, covering
the basic theory behind asynchronous and event-driven development,
performance, installation, CPU utilisation, modules, Express,
EventEmitter, SQLite3, and even Mongoose.

If you're a web developer struggling to understand Node, then Node Web
may help you get up to speed quickly. For more information,
take a look at the Node Web Development table of

and Chapter 3: Node


Node.js in Action

Node.js in Action (Price: \$39.99, Ebook: \$31.99, Publisher: Manning) by Mike Cantelon and TJ Holowaychuk
is currently available as part of Manning's Early Access Program, which
means you can subscribe to read the book as chapters are finished.

The book is split into three parts, which cover the fundamentals, web
development, and "going further with Node" which appears to cover "stuff
that isn't web development". The first chapter is actually a
well-tempered argument on why we need Node, so it's worth considering
for boss-convincing ammunition. The second chapter explains how to
install Node for Windows, Mac OS X, and Linux, then goes on to make some
fun scripts like a little TCP/IP server accessed with

The authors waste no time diving right into asynchronous development in
chapter 3. This chapter is a solid treatment of asynchronous
programming, with EventEmitter taking centre stage, and coverage of
control flow techniques and tools.

Node.js in Action's estimated publishing date is April 2012, with 300
pages in the finished version. It's currently around 130 pages, so solid
progress has been made so far. Chapter 1: Why the Web needs
(PDF) is
available as a free sample chapter.


read (npm: read) by Isaac Z. Schlueter is billed as "read(1) for Node", and is intended to read lines
from the standard input.

var read = require('read');

read({ prompt: 'echo: ' }, function(err, res) {
  if (err) {
  } else {

Documentation is available in the project's README. Isaac notes that
care must be taken to manage process.stdin in certain
versions of Node:

In node 0.6.0 through 0.6.5, you must explicitly call process.stdin.destroy() or process.exit() when you know that your program is done reading, or else it will keep the event loop running forever.


XJST (GitHub: veged / xjst, npm: xjst) by Sergey Berezhnoy
is a Node and browser-compatible DSL for creating data transformations.
Suggested applications include HTTP request routing, template engines,
and parsers.

The authors have written some XJST
to help
people get the hang of the language. To use XJST, an input file must be
created using XJST's DSL. It reads like JavaScript, and XJST will
compile it into JavaScript. The
simple.xjst example is a good one for getting started.

If you're writing a parser of some kind but feel put off by something
like Jison, then XJST might help you get started without too much
