Source: http://mpvue.com/mpvue/index.html

展示如何在 mpvue 中定义 Vue 实例，并同时使用 Vue 和小程序特有的生命周期钩子。

```javascript
new Vue({
  data: {
    a: 1
  },
  created () {
    // `this` 指向 vm 实例
    console.log('a is: ' + this.a)
  },
  onShow () {
    // `this` 指向 vm 实例
    console.log('a is: ' + this.a, '小程序触发的 onshow')
  }
})
// => "a is: 1"
```

### Mpvue Page Component with TypeScript

Source: http://mpvue.com/build/mpvue-loader.html

Implements a page component in Mpvue using TypeScript and decorators. It demonstrates importing and registering child components like Card and CompB.

```typescript
// index.ts
import { Vue, Component } from 'vue-property-decorator'
import Card from '@/components/card.vue' // mpvue目前只支持的单文件组件
import CompB from '@/components/compb.vue' // mpvue目前只支持的单文件组件
// 必须使用装饰器的方式来指定component
@Component({
  components: {
    Card,
    CompB, //注意，vue的组件在template中的用法，`CompB` 会被转成 `comp-b`
  },
})
class Index extends Vue {
  ver: number = 123
  
  onShow() { // 小程序 hook
  }

  mounted() { // vue hook
  }
}

export default Index


```

--------------------------------

### Scoped Style Transformation in mpvue

Source: http://mpvue.com/build/mpvue-loader.html

Demonstrates how mpvue-loader modifies scoped styles by appending the module-id to class names directly, unlike vue-loader which uses attribute selectors.

```html
<!-- .vue -->
<template>
    <div class="container">
        // ...
    </div>
</template>
<style scoped>
    .container {
        color: red;
    }
</style>

<!-- vue-loader -->
<template>
    <div class="container" data-v-23e58823>
        // ...
    </div>
</template>
<style scoped>
    .container[data-v-23e58823] {
        color: red;
    }
</style>

<!-- mpvue-loader -->
<template>
    <div class="container data-v-23e58823">
        // ...
    </div>
</template>
<style scoped>
    .container.data-v-23e58823 {
        color: red;
    }
</style>

```

--------------------------------

### Implement Hot Reloading with webpack-dev-middleware-hard-disk

Source: http://mpvue.com/build/index.html

Configures the development server to map memory-cached files to the hard disk, enabling automatic refreshes in the WeChat DevTools.

```javascript
var config = require('./config')
if (!process.env.NODE_ENV) {
  process.env.NODE_ENV = JSON.parse(config.dev.env.NODE_ENV)
}

var path = require('path')
var webpack = require('webpack')
var webpackConfig = require('./webpack.dev.conf')
var compiler = webpack(webpackConfig)

require('webpack-dev-middleware-hard-disk')(compiler, {
  publicPath: webpackConfig.output.publicPath,
  quiet: true
})
```

--------------------------------

### 配置 resolve alias

Source: http://mpvue.com/build/index.html

```javascript
{
  resolve: {
    // ...
    alias: {
        'vue': 'mpvue',
        // ...
    }
  }
}
```

--------------------------------

### Configure Webpack Loaders for Mpvue and TypeScript

Source: http://mpvue.com/build/mpvue-loader.html

This webpack configuration adds 'mpvue-loader' and 'awesome-typescript-loader' to handle .vue and .tsx files, enabling TypeScript support within Mpvue.

```javascript
// webpack.conf.js
module.exports = {
  //...
  module: {
    rules: [
      {
        test: /\.vue$/,
        loader: 'mpvue-loader',
        options: {
          //...
          ts: [ //添加对应vue的loader
            'babel-loader',
            {
              // loader: 'ts-loader',
              loader: 'awesome-typescript-loader',
              options: {
                // errorsAsWarnings: true,
                useCache: true,
              }
            }
          ]
        }
      },
      // ts文件的loader
      {
        test: /\.tsx?$/,
        exclude: /node_modules/,
        use: [
          'babel-loader',
          {
            loader: 'mpvue-loader',
            options: {
              checkMPEntry: true
            }
          },
          {
            // loader: 'ts-loader',
            loader: 'awesome-typescript-loader',
            options: {
              // errorsAsWarnings: true,
              useCache: true,
            }
          }
        ]
      },
    ]
  // ...
  }


```

--------------------------------

### Mpvue App Component with TypeScript

Source: http://mpvue.com/build/mpvue-loader.html

Defines the root App component for a Mpvue application using TypeScript and decorators. It includes Mpvue lifecycle hooks like onLaunch, onShow, and onHide.

```typescript
//app.ts
import { Vue, Component } from 'vue-property-decorator'
declare module "vue/types/vue" {
  interface Vue {
    $mp: any;
  }
}

// 必须使用装饰器的方式来指定components
@Component({
  mpType: 'app', // mpvue特定
}as any)
class App extends Vue {
  // app hook
  onLaunch() {
    let opt = this.$root.$mp.appOptions
  }

  onShow() {
  }

  onHide() {
  }

  mounted() { // vue hook
  }
}

export default App


```

--------------------------------

### 模板语法限制示例

Source: http://mpvue.com/mpvue/index.html

展示模板中不支持的复杂 JS 表达式以及在事件处理函数中支持的用法。

```html
<!-- 这种就不支持，建议写 computed -->
<p>{{ message.split('').reverse().join('') }}</p>

<!-- 但写在 @event 里面的表达式是都支持的，因为这部分的计算放在了 vdom 里面 -->
<ul>
    <li v-for="item in list">
        <div @click="clickHandle(item, index, $event)">{{ item.value }}</p>
    </li>
</ul>
```

--------------------------------

### Set NODE_ENV to Production

Source: http://mpvue.com/build

Configure the NODE_ENV environment variable to 'production'. This is a simple way to manage environment settings, affecting build output such as whether to generate separate wxss files.

```javascript
process.env.NODE_ENV = 'production'

```

--------------------------------

### Mpvue Card Component with TypeScript

Source: http://mpvue.com/build/mpvue-loader.html

A reusable Card component for Mpvue implemented in TypeScript. It uses the @Prop decorator to define a reactive 'text' property and includes Mpvue lifecycle hooks.

```typescript
// card.ts
import { Vue, Component, Prop } from 'vue-property-decorator'
// 必须使用装饰器的方式来指定component
@Component
class Card extends Vue {
  @Prop({ default: '1' }) //注意用法！
  text: string;
  
  ver: number = 2;

  onShow() {
  }

  onHide() {
  }

  mounted() { // vue hook
  }
}

export default CompB


```

--------------------------------

### Remove Configuration from main.js

Source: http://mpvue.com/change-log/2018.7.24.html

Removes the config object from the main.js file as it is being migrated to app.json.

```javascript
-export default {
-  // 这个字段走 app.json
-  config: {
-    // 页面前带有 ^ 符号的，会被编译成首页，其他页面可以选填，我们会自动把 webpack entry 里面的入口页面加进去
-    pages: ['pages/logs/main', '^pages/index/main'],
-    window: {
-      backgroundTextStyle: 'light',
-      navigationBarBackgroundColor: '#fff',
-      navigationBarTitleText: 'WeChat',
-      navigationBarTextStyle: 'black'
-    }
-  }
-}
```

--------------------------------

### Add Global Whitelist to ESLint Configuration

Source: http://mpvue.com/build

Extend your .eslintrc.js configuration to include a global whitelist for specific variables. This prevents ESLint from flagging these globally available variables as undefined.

```javascript
{
  // ...
  globals: {
    App: true,
    Page: true,
    wx: true,
    getApp: true,
    getPage: true
  }
}

```

--------------------------------

### Vue Component for WeChat Mini Program

Source: http://mpvue.com/build/mpvue-loader.html

A Vue component template that will be transformed into WXML. It includes data binding and component composition.

```vue
<template>
    <div class="my-component">
        <h1>{{msg}}</h1>
        <other-component :msg="msg"></other-component>
    </div>
</template>
<script>
import otherComponent from './otherComponent.vue'

export default {
  components: { otherComponent },
  data () {
    return { msg: 'Hello Vue.js!' }
  }
}
</script>

```

--------------------------------

### Add Global Variables to .eslintrc.js

Source: http://mpvue.com/build/index.html

Defines global WeChat Mini Program objects in the ESLint configuration to prevent undefined variable errors.

```json
{
  // ...
  globals: {
    App: true,
    Page: true,
    wx: true,
    getApp: true,
    getPage: true
  }
}
```

--------------------------------

### Capture App Errors in Mpvue

Source: http://mpvue.com/mpvue/index.html

Implement an onError callback function on the app's root component to capture and log errors. This is a method for error capturing, not a full lifecycle.

```javascript
export default {
   // Only app has onLaunch lifecycle
   onLaunch () {
       // ...
   },

   // Capture app error
   onError (err) {
       console.log(err)
   }
}
```

--------------------------------

### 使用 computed 生成 Class

Source: http://mpvue.com/mpvue/index.html

展示通过 computed 属性生成 Class 字符串的推荐做法，以及不支持对象语法的示例。

```html
<template>
    <!-- 支持 -->
    <div class="container" :class="computedClassStr"></div>
    <div class="container" :class="{active: isActive}"></div>

    <!-- 不支持 -->
    <div class="container" :class="computedClassObject"></div>
</template>
<script>
    export default {
        data () {
            return {
                isActive: true
            }
        },
        computed: {
            computedClassStr () {
                return this.isActive ? 'active' : ''
            },
            computedClassObject () {
                return { active: this.isActive }
            }
        }
    }
</script>
```

--------------------------------

### Transformed WXML Template

Source: http://mpvue.com/build/mpvue-loader.html

The WXML output generated from a Vue component. It uses template imports and conditional rendering for child components.

```wxml
<import src="components/other-component$hash.wxml" />
<template name="component$hash">
    <view class="my-component">
        <view class="_h1">{{msg}}</view>
        <template is="other-component$hash" wx:if="{{ $c[0] }}" data-{{ ...$c[0] }}></template>
    </view>
</template>

```

--------------------------------

### Nested List Rendering in Vue Template

Source: http://mpvue.com/mpvue/index.html

When using nested v-for loops, ensure that different index aliases are specified for each loop to avoid conflicts. This is crucial for correct rendering in mpvue.

```Vue Template
<template>
    <ul v-for="(card, index) in list">
        <li v-for="(item, itemIndex) in card">
            {{item.value}}
        </li>
    </ul>
</template>
```

--------------------------------

### Vue Component Data Structure for mpvue

Source: http://mpvue.com/build/mpvue-loader.html

The tree-like data structure used by mpvue at runtime to manage component instances and pass data via setData.

```json
// 这儿数据结构是一个数组，index 是动态的
{
  $child: {
    '0':{
      // ... root data
      $child: {
        '0': {
          // ... data
          msg: 'Hello Vue.js!',
          $child: {
            // ...data
          }
        }
      }
    }
  }
}
