A tiny JavaScript MVVM library with Virtual DOM. It has only ~600 lines of code.

Usage

ES2015

import { init, el } from 'aoy';

//1. init aoy.
const myAoy = init();
conse store = myAoy.store;

//2. add a store to aoy instance.
store.add('firstStore',{txt: 'this is a P'});

//3. create a component.
const myP = aoy.createComponent({
                el: document.body,
                render: function(){
                    return el('p', this.firstStore.txt);
                }
            });
            
//4. component connect to a store, view will be render immediately.
myAoy.connect(myP, 'firstStore');

//5. when u update this component's store, view will be render again.
store.get('firstStore').txt = 'change view';

CommonJS

var myAoy = require('aoy').init();
var el = myAoy.el;

Browser globals

The dist folder contains aoy.js and aoy.min.js.

<script src="path/to/aoy.js"></script>
<script>
var aoy = Aoy.init();
var store = aoy.store;
var el = aoy.el;
</script>

Examples

Api

aoy.init

init function returns a aoy instance.

aoy.el(selectors, props, children])

return a Virtual DOM.

var span = el('span','this is p') // render <span>this is p</span>
var p = el('div',[ span ]) // render <p><span>this is p</span></p>
var div = el('div#mydiv.classA.classB') // render <div id="mydiv" class="classA classB"></div>

aoy.createComponent(descriptor)

descriptor is Object

descriptor.el:

it is a HTMLElement for component's parentNode.

descriptor.render:

render functon returns vnode.

var inputStore = store.get('inputStore');
var myinput = aoy.createComponent({
	inputFn: function(){
		
	},
	render: function(){
		return el('Input', {
                        oninput: this.inputFn,
                        placeholder: this.inputStore.value,
                        type: 'text' 
				});
	}
});

aoy.connect(component[,stores])

when connect function is called, Virtual DOM will be rendered immediately.

var aoy.connect(mycomponent, 'a') // mycomponent denpend on a.
var aoy.connect(mycomponent, ['a', 'b']) // mycomponent denpend on a and b.

store

aoy instance provides a store.

var aoy = Aoy.init();
var store = aoy.store;

store.add([key ,] data)

function add is used to save data. if no key, this data's key is _DEFAULT.

aoy.store.add('a',{b:1}) // a:{b:1}
aoy.store.add({b:1}) // _DEFAULT:{b:1}

store.get(key)

Return to the corresponding store's data

aoy.store.add('a',{b:1})
aoy.store.get('a') // return {b: 1}

sotre.set(newData)

update data.

aoy.store.add('a',{b:1})

aoy.store.get('a').set({a:1, b:2}) //same: aoy.store.get('a') = {a:1, b:2}

aoy.store.get('a') // return {a:1, b:2}

Note

support IE 10 and up + all modern browsers.
aoy only data-binding one-level key, if data has deep structure, suggest to cooperate immutable-js .
