Fairmont-Reactive

Fairmont-Reactive is a JavaScript library for functional reactive programming. It's part of the Fairmont library. You can use it by itself, or simply as part of the Fairmont library.

Installation

npm install fairmont-reactive

Examples

Here's a simple reactive Web app implementing a counter using Fairmont's Reactive programming functions.

In JavaScript:

var $ = require("jquery"),
  F = require("fairmont");
 
$(function() {
 
  var data = { counter: 0 };
 
  F.go([
    F.events("click", $("a[href='#increment']")),
    F.map(function() { data.counter++; })
  ]);
 
  F.go([
    F.events("change", F.observe(data)),
    F.map(function() {
      $("p.counter")
        .html(data.counter);
    })
  ]);
});
 

In CoffeeScript:

{start, flow, events, map, observe} = require "fairmont-reactive"
 
$ = require "jquery"
 
$ ->
 
  data = counter: 0
 
  go [
    events "click", $("a[href='#increment']")
    map -> data.counter++
  ]
 
  go [
    events "change", observe data
    map ->
      $("p.counter")
      .html data.counter
  ]

Status

[Fairmont][0] is still under heavy development and is beta quality, meaning you should probably not use it in your production code.
