QuartermasterJS

QuartermasterJS is a small, modular JavaScript library providing:

• functional style programming with filter, map, fold and reduce functions
• reactive programming constructs: signal, event streams and promises
• promise based modules for browser based JavaScript, domready, script-loader and ajax
• a webstorage module with a consistent API for local, session and cookie based storage
• a small, simple module management system using named modules with require and define

Quartermaster started out as a small core library for use by other modules, e.g. reactive event streams and signals and promise based APIs such as domready.

QuartermasterJS has no other dependencies.

The core module provides most of the common higher order functions e.g 'forEach, filter, and map used in functional programming. Other modules can be used as required to provide additional functions for working with arrays and objects.

Sub Modules

• 'qm-js/lib/array' - provides tail, head, drop, take, partition, zip,compact, flatten
• 'qm-js/lib/object' - provides versions of filter and map which return transformed objects
• 'qm-js/lib/function' - provides partial, partialr, curry
• 'qm-js/lib/promise' - Promise.resolve, Promise.reject, Promise.all, Promise.race and Promise.defer
• 'qm-js/lib/reactive'- provides EventStream and Signal classes
• 'qm-js/lib/option' - based on Scala's Option type for representing optional values
• 'qm-js/lib/try' - based on Scala's Try to represent a computation that may either result in an exception or return a successfully computed value
• 'qm-js/lib/lens' - functional lens implementation
• 'qm-js/lib/collection' - provides BoundedStack and OrderedMap implementations

Installation

    npm install qm-js

For use in the browser, you can use any of the popular tools such as Browserify or webpack to package Quartermaster and any its modules according to your current workflow or needs. All of Quartermaster's components are simple CommonJS modules using module.exports.

Quartermaster also provides a small (792 bytes minified), simple module system that can be used. A version of Quartermaster for use with this module system can found under lib/module.
