bigint

bigint by James Halliday is an arbitrary precision arithmetic library for Node. Large integers can
be defined with strings, then manipulated with the library's methods:

var bigint = require('bigint');

var b = bigint('782910138827292261791972728324982')
    .sub('182373273283402171237474774728373')
    .div(8);

Note that there's also a destroy method:

Destroy a bigint. This module is using node-ffi so I can't hook onto the GC easily. You only need to call this if you're creating bigints in a loop.

Other methods include rand, pow, and more.
This library can be installed with npm install bigint.

I actually have some experience in working with arbitrary precision
arithmetic from back in my university days -- I wrote a distributed
fractal generator with various numerical libraries. In Ada... This
sounds like a lot more fun!

Mingy

I like writing CLI stuff, so I thought
Mingy by Mike Cantelon sounded pretty cool. He describes it as a "cheap and cheerful command
parser/server for node.js", perfect for creating command-line tools,
text adventure games, and even MUDs.

It can run as a server (hence the MUD reference), copes with multiple
users, includes validation support, and even has Expresso tests.

kyoto-client

kyoto-client (GitHub: wezm / kyoto-client, BSD License) by
Wesley Moore is a Kyoto Tycoon client
library. Kyoto Tycoon is a lightweight database server, from FAL Labs,
who also created the older Tokyo Cabinet key value database.

The kyoto-client module has some good documentation on the site and
seems straightforward to use. It can be installed with npm install
kyoto-client
.

Blagovest's NPM Search

Blagovest's NPM Search by Blagovest Dachev is a convenient (and fast) way to browse npm. In fact, it's
exactly the kind of thing I need to find things to write about for
DailyJS. Thanks Blagovest!
