define state

DEPRECATION NOTICE

Just use st8 directly as:

``js
import State from 'st8'

var state = new State({
a(){
// onenter
this === target //true
},

b(){
// onenter
this === target //true
return () => {
// onexit
}
}

}, target);

Object.defineProperty(target, property, {
set: function (value) {
return state.set(value);
},
get: function () {
return state.get();
}
});
`

---

Define stateful property on class instance or any object. Behaves like defineProperty, but defines a state.

$ npm install define-state

`js
var defineState = require('define-state');

function MyComponent (el) {
this.el = el;

//define state on instance
defineState(this, 'state', this.state);

//go to initial state
this.state = true;
}

//state declaration
MyComponent.prototype.state = {
true: {
before: function () {
this.el.innerHTML = 'Hello world!';
}
}
}

//create instance
new MyComponent(document.querySelector('#hello'));
`

API

$3

Define stateful property name on a target according to the state declaration (see st8 API). Pass optional isFn argument to define functional accessor instead of getter/setter, might be useful for IE8/ES3 environments or to define functional-style components, like dialog.

`js
defineState(target, 'visible', {
true: function () {
this.removeAttribute('hidden');
},
false: function () {
this.setAttribute('hidden', true);
}
}, true);

target.visible(false);
