Redis Implemented With Node
Nedis is a (partial) redis implementation written with node. Primarily for fun, however as our team grows larger, and as we add more non-technical team members over at LearnBoost I figured it would be nice help prevent the need for compiling development dependencies.
Nedis is an old side project I had going, and is no where near complete, but it does work, so I figured I would open-source it....

Stylus 0.4.0 released
Stylus for those who are not familiar with it, is a dynamic language which compiles down to css, written with JavaScript for node.js.
CSS Syntax Support
Previously Stylus only allowed the use of our indented grammar, which may deter designers that are not comfortable learning or using a new syntax. For this reason and to aid in copy/pasting of css stylesheets I have added support for optional...

thechangelog:
This isn’t the first time we’ve covered the latest fresh and new creation from LearnBoost.
Stylus is an expressive, dynamic, robust CSS pre-processor for Node.js. If you are familiar with Sass.js, Sass or Less.js … Stylus is kind of similar, but from what we’ve heard from TJ Holowaychuk they’ve taken it pretty far in a new direction.
At first glance, Stylus looks a lot like...

Introducing Tobi
A few days ago we released another small test related project named Tobi for nodejs. Tobi is similar to Ruby tools such as Capybara or Webrat in fulfilling the need for headless acceptance testing. Tobi utilizes jQuery and node’s jsdom to give you an expressive foundation for testing your application in a familiar way.
Motivation
For those of you who follow our work at LearnBoost we have...

Jade Templates Introspection
The Jade Template Engine for Node now have the ability to manipulate themselves based on the parse tree constructed from a nested block. This has extreme potential, in that developers can now alter jade templates dynamically, constructing their own syntactic sugar.
One of my favorite (but not only) use-cases for this functionality, would be that of a database record edit form. Typically your...

C Indentation Based Language Lexer Tutorial
C Indentation Based Language Lexer Tutorial
In this tutorial I wanted to show you how you can start your own programming language, starting by creating what is commonly referred to as a lexer or scanner. The grammar for our “language” will be indentation based much like Python, however will implement a tiny subset of tokens for illustration purposes. If you prefer, you may also jump...

C Insertion Sort
So I wanted to investigate different sorting algorithms for a few personal projects, and I thought while I was doing so that I would write little tutorials for each algo :) why not! First we have one of the most basic sorting algorithms, the Insertion Sort.
Explanation
As illustrated by this video, the insertion sort works much like you might sort a deck of cards laying infront of you on a...

nDistro - Node distribution toolkit
nDistro is a small bash project that allows you to define, and install node distributions within seconds. This means no GIT dependency, no compiling node from source with Make, no need to install node then install npm (node’s package manager).
nDistro distributions are easy to create, share, and install. Before we get into the details lets install nDistro:
$ cd /usr/local/bin &&...

Express 1.0beta
Yesterday I released Express 1.0.0beta, a Sinatra inspired Node web development framework.
The beta is a near re-write consisting of roughly 300 commits, introducing new features,
removing legacy code, and improving documentation. Express now runs on the Connect middleware framework, which replaces the
previous concept of a Plugin. The performance of express has also been optimized and can
now...

Node JavaScript Test Coverage
Today I released Expresso 0.4.0, a TDD framework for node which uses my node-jscoverage project to instrument your library, providing optional test coverage reporting when the —cov flag is used.
Expresso
If you dont know anything about expresso, it executes tests in parallel, so even ~1000 assertions against live http servers can execute in less than a second. By doing so we unfortunately...

Jade - Haml killer for nodejs
Last night I open sourced my latest project Jade, a template engine for node, focusing on readability, error handling and performance. Jade spawned from several needs, first I was tired of debugging poor JavaScript template implementations, or finding work-arounds for common issues, secondly I love haml’s syntax, however I feel it could be revamped to provide a more enjoyable experience, and...

Connect vs JSGI
Last week Kris Zyp posted JSGI vs Connect, claiming that Connect is slower than JSGI.
Another claim is that JSGI is far more intuitive, which I consider false. First of all the library does not follow common nodejs idioms, and the configuration also causes the “boomerang effect”, although in the end only the community will decide what they want.
Krisbenchmarks generally consisted...

Connect - Middleware For NodeJS
Yesterday myself and Tim Caswell open-sourced
the first Ext JS nodejs project, Connect.
Connect is an abstraction layer, providing node developers with an effective, high performance solution
for rapid development using interchangable components called “middleware”.
Middleware
Middleware provides node developers with simple “plug and play” modules,
which may be stacked...

Expresso - TDD Framework For NodeJS
A few days ago I rolled out a new TDD framework for Node. Although node has many BDD and TDD frameworks to offer, I wanted a simple, fast, and thin layer built upon node’s core assert module. Among other features I wanted an executable that I could re-use for my future node projects, this project is named expresso.
Performance
Although expresso stands short in the reporting department,...
