+# WebCell 从 v2 到 v3 的迁移
+
+## 类 React 状态管理已被完全移除
+
+**WebCell v3** 受到了 [**MobX** 的 **本地可观察状态** 思想][1] 的深刻启发，[不仅仅是 React][2]，Web Components 可以更轻松地管理 **内部状态和逻辑**，无需任何复杂的操作：
+
+1. 状态类型声明
+2. `this.state` 声明及其类型注解/断言
+3. `this.setState()` 方法的调用及其回调
+4. 令人困惑的 _Hooks API_...
+
+只需像管理 **全局状态** 一样声明一个 **状态存储类**，并在 `this`（即 **Web Component 实例**）上初始化它。然后像 [MobX][3] 一样使用并观察这些状态，一切就完成了。
+
+```diff
+import {
+    component,
++   observer,
+-   mixin,
+-   createCell,
+-   Fragment
+} from 'web-cell';
++import { observable } from 'mobx';
+
+-interface State {
++class State {
++   @observable
+-   key: string;
++   accessor key = '';
+}
+
+@component({
+    tagName: 'my-tag'
+})
++@observer
+-export class MyTag extends mixin<{}, State>() {
++export class MyTag extends HTMLElement {
+-   state: Readonly<State> = {
+-       key: 'value'
+-   };
++   state = new State();
+
+-   render({}: any, { key }: State) {
++   render() {
++       const { key } = this.state;
+
+        return <>{value}</>;
+    }
+}
+```
+
+同时，`shouldUpdate() {}` 生命周期方法已被移除。你只需在 `State` 类的方法中，在状态改变之前控制逻辑即可。
+
+## DOM 属性变为可观察数据
+
+**DOM 属性** 不同于 React 的 props，它们是 **响应式的**。它们不仅负责 **更新组件视图**，还会与 **HTML 属性同步**。
+
+MobX 的 [`@observable`][4] 和 [`reaction()`][5] 是实现上述功能的优秀 API，代码也非常清晰，因此我们添加了 `mobx` 包作为依赖：
+
+```shell
+npm install mobx
+```
+
+另一方面，[`mobx-web-cell` 适配器][6] 已经合并到了核心包中。
+
+```diff
++import { JsxProps } from 'dom-renderer';
+import {
+-   WebCellProps,
+    component,
+    attribute,
+-   watch,
++   observer,
+-   mixin,
+-   createCell,
+-   Fragment
+} from 'web-cell';
+-import { observer } from 'mobx-web-cell';
++import { observable } from 'mobx';
+
+-export interface MyTagProps extends WebCellProps {
++export interface MyTagProps extends JsxProps<HTMLElement> {
+    count?: number
+}
+
+@component({
+    tagName: 'my-tag'
+})
+@observer
+-export class MyTag extends mixin<MyTagProps>() {
++export class MyTag extends HTMLElement {
++   declare props: MyTagProps;
+
+    @attribute
+-   @watch
++   @observable
+-   count = 0;
++   accessor count = 0;
+
+-   render({ count }: MyTagProps) {
++   render() {
++       const { count } = this;
+
+        return <>{count}</>;
+    }
+}
+```
+
+## 使用 Shadow DOM 的 `mode` 选项控制渲染目标
+
+### 渲染到 `children`
+
+```diff
+import {
+    component,
+-   mixin
+} from 'web-cell';
+
+@component({
+    tagName: 'my-tag',
+-   renderTarget: 'children'
+})
+-export class MyTag extends mixin() {
++export class MyTag extends HTMLElement {
+}
+```
+
+### 渲染到 `shadowRoot`
+
+```diff
+import {
+    component,
+-   mixin
+} from 'web-cell';
+
+@component({
+    tagName: 'my-tag',
+-   renderTarget: 'shadowRoot'
++   mode: 'open'
+})
+-export class MyTag extends mixin() {
++export class MyTag extends HTMLElement {
+}
+```
+
+## 将 Shadow CSS 注入移动到 `render()`
+
+这样使得 **Shadow CSS** 可以随着可观察数据的更新而响应。
+
+```diff
++import { stringifyCSS } from 'web-utility';
+import {
+    component,
+-   mixin
+} from 'web-cell';
+
+@component({
+    tagName: 'my-tag',
+-   renderTarget: 'shadowRoot',
++   mode: 'open',
+-   style: {
+-       ':host(.active)': {
+-           color: 'red'
+-       }
+-   }
+})
+-export class MyTag extends mixin() {
++export class MyTag extends HTMLElement {
+    render() {
+        return <>
++           <style>
++               {stringifyCSS({
++                   ':host(.active)': {
++                       color: 'red'
++                   }
++               })}
++           </style>
+            test
+        </>;
+    }
+}
+```
+
+## 替换部分 API
+
+1. `mixin()` => `HTMLElement` 及其子类
+2. `mixinForm()` => `HTMLElement` 和 `@formField`
+3. `@watch` => `@observable accessor`
