mk-meta-engine/example/apps/demo/data.js

元数据化引擎，在mk-app-loader实现的应用隔离基础上，实现可以用json元数据描述界面模型，并提供了action、reducer的基础函数和monkeyKing组件.

export function getMeta() {
	return {
		name: 'root',
		component: '::div',
		children: [{
			name: 'hello',
			component: '::div',
			children:'hello'
		}, {

			children: 'user:',
			_visible: '{{data.isLogin !== true}}'
		}, {

			onChange: "{{ (e) => $setField('data.form.user', e.target.value ) }}",
