<li>安装<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">npm install --save mobx mobx-react</span><br></pre></td></tr></table></figure></li>
<li>核心概念</li>
</ol>
<ul>
<li>state(状态)
状态是驱动应用的数据。</li>
<li>observable(value) && @observable
Observable 值可以是JS基本数据类型、引用类型、普通对象、类实例、数组和映射。其修饰的state会暴露出来供观察者使用。</li>
<li>observer(观察者)
被observer修饰的组件，将会根据组件内使用到的被observable修饰的state的变化而自动重新渲染。</li>
<li>action(动作)
只有在 actions 中，才可以修改 Mobx 中 state 的值。
action–>state–>view</li>
<li>computed
计算值(computed values)是可以根据现有的状态或其它计算值衍生出的值。(可以看成公式)
getter：获得计算得到的新state并返回。
setter：不能用来直接改变计算属性的值，但是它们可以用来作”逆向”衍生。</li>
<li>autorun
这通常是当你需要从反应式代码桥接到命令式代码的情况，例如打印日志、持久化或者更新UI的代码。</li>
<li>如果你有一个函数应该自动运行，但不会产生一个新的值，请使用autorun。 其余情况都应该使用 computed。</li>
<li>reactions
Reactions 和计算值很像，但它不是产生一个新的值，而是会产生一些副作用，比如打印到控制台、网络请求、递增地更新 React 组件树以修补DOM、等等。 简而言之，reactions 在 响应式编程和命令式编程之间建立沟通的桥梁。</li>
