### Configure easycom Rules in pages.json

Source: https://github.com/yx159247/mp_take_out/blob/master/takeout_mp/uni_modules/uview-ui/README.md

Configures the easycom rules in pages.json to enable on-demand component loading. This eliminates the need for manual imports. The example shows configurations for both npm and direct download installations.

```js
// pages.json
{
	"easycom": {
		// npm安装的方式不需要前面的"@/"，下载安装的方式需要"@/"
		// npm安装方式
		"^u-(.*)": "uview-ui/components/u-$1/u-$1.vue"
		// 下载安装方式
		// "^u-(.*)": "@/uview-ui/components/u-$1/u-$1.vue"
	},
	// 此为本身已有的内容
	"pages": [
		// ......
	]
}
```

### Initialize Global Site Configuration (window.SITE_CONFIG)

Source: https://github.com/yx159247/mp_take_out/blob/master/renren-ui/public/index.html

This JavaScript code initializes the `window.SITE_CONFIG` object, which holds global application settings. It defines properties such as application version, environment variables, Vuex store state, content tab defaults, menu lists, permissions, and dynamic routes. API and WebSocket URLs are conditionally set based on the `VUE_APP_NODE_ENV` environment variable, supporting different endpoints for development, SIT, UAT, and production environments.

```JavaScript
window.SITE_CONFIG = {};
window.SITE_CONFIG['version'] = 'v5.0.0';
window.SITE_CONFIG['nodeEnv'] = '<%= process.env.VUE_APP_NODE_ENV %>';
window.SITE_CONFIG['apiURL'] = ''; // api请求地址
window.SITE_CONFIG['storeState'] = {}; // vuex本地储存初始化状态（用于不刷新页面的情况下，也能重置初始化项目中所有状态）
window.SITE_CONFIG['contentTabDefault'] = { // 内容标签页默认属性对象
  'name': '', // 名称, 由 this.$route.name 自动赋值（默认，名称 === 路由名称 === 路由路径）
  'params': {}, // 参数, 由 this.$route.params 自动赋值
  'query': {}, // 查询参数, 由 this.$route.query 自动赋值
  'menuId': '', // 菜单id（用于选中侧边栏菜单，与this.$store.state.sidebarMenuActiveName进行匹配）
  'title': '', // 标题
  'isTab': true, // 是否通过tab展示内容?
  'iframeURL': '' // 是否通过iframe嵌套展示内容? (以http[s]://开头, 自动匹配)
};
window.SITE_CONFIG['menuList'] = []; // 左侧菜单列表（后台返回，未做处理）
window.SITE_CONFIG['permissions'] = []; // 页面按钮操作权限（后台返回，未做处理）
window.SITE_CONFIG['dynamicRoutes'] = []; // 动态路由列表
window.SITE_CONFIG['dynamicMenuRoutes'] = []; // 动态(菜单)路由列表
window.SITE_CONFIG['dynamicMenuRoutesHasAdded'] = false; // 动态(菜单)路由是否已经添加的状态标示（用于判断是否需要重新拉取数据并进行动态添加操作）
<% if (process.env.VUE_APP_NODE_ENV === 'dev') { %>
window.SITE_CONFIG['apiURL'] = 'http://localhost:8080/api';
window.SITE_CONFIG['webSocketURL'] = 'ws://localhost:8080/api';
<% } %>
<% if (process.env.VUE_APP_NODE_ENV === 'prod:sit') { %>
window.SITE_CONFIG['apiURL'] = 'http://localhost:8080/api';
window.SITE_CONFIG['webSocketURL'] = 'ws://localhost:8080/api';
<% } %>
<% if (process.env.VUE_APP_NODE_ENV === 'prod:uat') { %>
window.SITE_CONFIG['apiURL'] = 'http://localhost:8080/api';
window.SITE_CONFIG['webSocketURL'] = 'ws://localhost:8080/api';
<% } %>
<% if (process.env.VUE_APP_NODE_ENV === 'prod') { %>
window.SITE_CONFIG['apiURL'] = 'https://localhost:8080/api';
window.SITE_CONFIG['webSocketURL'] = 'wss://localhost:8080/api';
<% } %>

### Implement User Authorization Login Page in Uni-app Vue

Source: https://github.com/yx159247/mp_take_out/blob/master/takeout_mp/uni_modules/tuniaoui-wx-user-info/readme.md

This snippet demonstrates a Uni-app Vue component for a login page that includes a user authorization modal. It shows how to import and use the `wx-user-info-modal` component, control its visibility with `v-model`, and handle the `updated` event to receive user information. It also includes basic styling for the login page and authorization button.

```Vue
<template>
	<view class="login-page">
    <!-- 授权登录按钮 -->
    <view class="submit-btn"  @tap.stop="openAuthorizationModal">
      授权登录
    </view>
    
    
    <wx-user-info-modal
      v-model="showAuthorizationModal"
      @updated="updatedUserInfoEvent"
    ></wx-user-info-modal>
	</view>
</template>

<script>
  import WxUserInfoModal from '@/uni_modules/tuniaoui-wx-user-info/components/tuniaoui-wx-user-info/tuniaoui-wx-user-info.vue'
  
	export default {
    components: { WxUserInfoModal },
		data() {
			return {
				showAuthorizationModal: false
			}
		},
		onLoad() {

		},
		methods: {

      // 打开获取用户信息弹框
      openAuthorizationModal() {
        this.showAuthorizationModal = true
      },
      
      // 获取到的用户信息
      updatedUserInfoEvent(info) {
        console.log('获取到的用户信息', info)
      },
      
      
		}
	}
</script>

<style>
	.login-page {
    width: 100vw;
    height: 100vh;
    display: flex;
    align-items: center;
    justify-content: center;
  }
  
  /* 授权按钮 */
  .submit-btn {
    width: 100%;
    background-color: #05C160;
    color: #FFFFFF;
    margin-top: 60rpx;
    border-radius: 10rpx;
    padding: 25rpx;
    font-size: 32rpx;
    display: flex;
    align-items: center;
    justify-content: center;
    margin: 30rpx;
  }
</style>
```

### Import Global SCSS Variables in uni.scss

Source: https://github.com/yx159247/mp_take_out/blob/master/takeout_mp/uni_modules/uview-ui/README.md

Imports the global SCSS variable file from uView UI into uni.scss. This file contains theme-related variables that can be customized.

### Upgrading mescroll to uni_modules version (1.3.5+)

Source: https://github.com/yx159247/mp_take_out/blob/master/takeout_mp/uni_modules/mescroll-uni/readme.md

Instructions for users to upgrade their mescroll component to the 1.3.5+ uni_modules version. This process involves removing old component files and registrations, importing the new version, updating import paths, and leveraging easycom compliance for mescroll-empty.

```Plaintext
1. 删除原来的 @/components/mescroll-uni 组件
2. 删除 main.js 注册的 mescroll 组件
3. 从插件市场导入最新mescroll组件 (1.3.5+uni_modules版本)
4. 全局搜索 '@/components/mescroll-uni/' 替换为 '@/uni_modules/mescroll-uni/components/mescroll-uni/'
5. mescroll-empty遵循easycom规范, 若某些页面单独使用 'mescroll-empty.vue', 可删除手动导入的代码
```

### Dynamically Configure Mobile Viewport for Safe Area Support in JavaScript

Source: https://github.com/yx159247/mp_take_out/blob/master/takeout_mp/index.html

This JavaScript snippet detects support for CSS `env()` or `constant()` functions, which are used to define safe areas on mobile devices (e.g., iPhones with notches). Based on this detection, it dynamically injects or updates the `viewport` meta tag to include `viewport-fit=cover`, ensuring the web content correctly utilizes the full screen, including areas under device notches or rounded corners. This is essential for a seamless full-screen experience on modern mobile browsers.

```JavaScript
var coverSupport = 'CSS' in window && typeof CSS.supports === 'function' && (CSS.supports('top: env(a)') || CSS.supports('top: constant(a)'))
document.write( '<meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0' + (coverSupport ? ', viewport-fit=cover' : '') + '" />')
```

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

### Import Base Styles in App.vue

Source: https://github.com/yx159247/mp_take_out/blob/master/takeout_mp/uni_modules/uview-ui/README.md

Imports the core SCSS styles for uView UI into the App.vue component. It is crucial to declare lang="scss" on the <style> tag to enable SCSS processing.

```scss
/* App.vue */
<style lang="scss">
@import "uview-ui/index.scss";
</style>
```
