# mosaic-reactive

A very simple reactive framework inspired by the http://reactivex.io/. Features:

• 350 lines of code; 8Kb (non minimized)
• Based on PromiseA-compliant promises; can be used with any external promise implementations.
• Each stream is a deferred object with resolve/reject/then methods. Main methods:
  • Deferred
  • Stream
• Provides the following methods:
  • buffered
  • each
  • filter
  • index
  • map
  • merge
  • pipe
  • zip
• Experimental methods
  • delay
  • interval

Example:

// var Promise = require('promise'); // - not required in NodeJS environment 
var reactive = require('mosaic-reactive');

var source = reactive.Stream(Promise, {
	methods : reactive
});

var out = source.map(function(value) {
	return value.toUpperCase();
}).each(function(value) {
	console.log('* ', value);
});

var array = [ 'first', 'second', 'third', 'fourth', 'fifth' ];
array.forEach(source.emit);
source.end();

return out.then(function() {
	console.log('Finished');
}, function(err) {
	console.log('Error!', err);
});
