Poor Man's Flux, a really simple React/functional based flux alternative. Read more

The real power of Flux comes from mantaining the unidirectional flow of data from Dispatcher to Actions to Stores to Components.

With poormansflux we keep it simple, just add the poorMansFluxMixin to the top component of your hierarchy.

The poorMansFluxMixin accepts two parameters: Initial Store value and a actions construct (described below)

var
	App,
	poorMansFluxMixin,
	React;
	
React = require('react');
poorMansFluxMixin = require('poormansflux);

App = React.createClass({
	mixins: [poorMansFluxMixin({key: 'value'}, myActions)],
	
	...
});

Actions are defined by a function construct that receives two arguments: a store dispatcher and the flux construct (flux is an object that contains two properties: store and actions)

myActions = function(dispatch, flux) {
  return {
    increaseNumber: function() {
      dispatch({value: flux.store.value + 1});
    },
    decreaseNumber: function() {
      dispatch({value: flux.store.value - 1});
    }
  };
};

In your top component (the one with the mixin) all children components have access to a flux object on this.context (They have to define it to gain access)

var
	Button,
	React;

React = require('react');

Button = React.createClass({
	render: function() {
		<button onClick={this.increase}>{this.context.store.value}</button>
	},
	
	increase: function(evt) {
		this.context.flux.actions.increaseNumber();
	},
	
	contextTypes: {
		flux: React.PropTypes.object
	}
});

As you can see, Action get called, stores get changed, components get redrawn on a circular fashion.

This library was created for academic purpouses, maybe a occasional use on small interfaces where using other Flux libraries would be an overkill.

Updated on version 0.1.5

You can now pass a callback on dispatch as:

myActions = function(dispatch, flux) {
  return {
    increaseNumber: function() {
      dispatch({value: flux.store.value + 1}, function() { ... });
    },
    decreaseNumber: function() {
      dispatch({value: flux.store.value - 1});
    }
  };
};
