base85 implements Base85 encoding and decoding for Node.js. It supports the most commonly known specifications; ascii85, zeromq, and ipv6 (RFC1924). It is excellent for encoding arbitrary (possibly binary) data into a text string which can easily be copy-pasted to source code files or e-mails.
MyRPC is a remote procedure call framework designed to easily connect heterogeneous systems. It features IDL-based client and server stub generation, cross-platform capability, binary protocol (no need for escaping of binary data, less overhead), support for various data types (like string, binary, signed and unsigned integers, floating point, list, structure, and enumeration), and exception support. It has no external dependencies.
Roosevelt is a Web framework for Node.js which uses Teddy for HTML templating, LESS for CSS preprocessing, and Closure Compiler for JS minification by default. It is designed to be configurable so you can supply your own templating system, CSS preprocessor, or JS minifier if you like. Built on Express, Roosevelt is designed to abstract all the crusty boilerplate necessary to build a typical Express app, sets sane defaults with mechanisms for override, and provides a uniform MVC structure for your app.
MPDisco is a Node.js-based music server built to let teams and groups control a single music player together. Accessing an MPDisco server puts each user, after logging in, in a rotating DJ queue. Each user will be given one hour (by default) to control the playlist and music player.
Canumb aims to crunch data on various forms and turn them into something meaningful. A variety of inputs are currently supported, such as different number base conversions (decimal to hexadecimal, binary to hexadecimal, octal to decimal, etc.) and various encoded formats (a base64 encoder decoder and a URI encoder decoder). It's built to allow for extension when the future demands other input formats be crunched.
