meteor-statemachine

BASED on natestrauser:statemachine but with fix nate-strauser/meteor-statemachine#3 due to "ReferenceError: StateMachine is not defined"

StateMachine.js packaged for meteor

See https://github.com/jakesgordon/javascript-state-machine and http://codeincomplete.com/posts/2014/3/15/javascript_state_machine_v2_3_0/

exposes StateMachine as a global variable on both client and server

simple example based on a observe query

Meteor.startup(function () {
    var fruitEvents = [
        { name: 'eat',  from: 'start',  to: 'finished' },
        { name: 'fail', from: '*', to: 'failed'  }
    ];

    var fruitCallbacks = {
        oneat: function(event, from, to, fruit) {
            Fruit.update(fruit._id, {$set: {
                'state':to
            }});
        },
        onfail: function(event, from, to, fruit) {
            Fruit.update(fruit._id, {$set: {
                'state':to
            }});
        }
    };

    var fruitStateMachine = function(fruit){
        var stateMachine = StateMachine.create({
            initial: fruit.state,
            events: fruitEvents,
            callbacks: fruitCallbacks
        });
        switch (fruit.state) {
            case "start":
                <do something>
                stateMachine.eat(fruit);
                break;
        }
    };

    Fruit.find({'state': 'start'}).observe({
        added: fruitStateMachine
    });
});
