uniapp vue3 vscode快速开发配置 使用 pinia 持久化数据，数据加密，unocss

Uniapp Vue3/Vite Typescript

命令安装

文档

npx degit dcloudio/uni-preset-vue#vite-ts my-vue3-project

gitee 模板下载

vscode 快速开发插件

• uni-create-view

快速创建 uniapp 视图与组件!

配置

@ext:mrmaoddxxaa.create-uniapp-view

• uni-helper

uniapp 代码提示

• uniapp 小程序扩展

鼠标悬浮在 api 上面会提示文档

ts 类型校验

校验属性值错误提示

pnpm add -D @types/wechat-miniprogram @uni-helper/uni-app-types

tsconfig.json

{
	"compilerOptions": {
		"types": ["@dcloudio/types", "node", "@uni-helper/uni-app-types"],
		"ignoreDeprecations": "5.0"
	},
	"vueCompilerOptions": { "nativeTags": ["block", "component", "template", "slot"] },

}

vscode 允许 manifest.json 等文件注释

files.associations

pnpm add @types/uni-app -D

pnpm add  @types/uni-app -D

获取安全距离

const { safeAreaInsets } = uni.getSystemInfoSync();
// {top: 20, left: 0, right: 0, bottom: 0}
console.log(11, safeAreaInsets);

使用 onLoad 等生命周期

import { onLoad } from "@dcloudio/uni-app";

onLoad(() => {});

• 传参，接收参数

// 传参
uni.navigateTo({ url: '/member/setting/setting?id=1' });


<script lang="ts" setup>
// 接收参数一
onLoad(e => {
  console.log(e);
});

// 接收参数二 vue3中写法
const props = defineProps<{ id: number }>();
console.log(' ~ props:', props);
</script>

使用分包和预下载

优化小程序的下载和启动速度

在 pages 同级目录下新建 member 目录

pages.json

  // 分包加载配置
  "subPackages": [
    {
      // 子包的根目录
      "root": "member",
      // 子包由哪些页面组成，参数同 pages
      "pages": [
        {
          "path": "setting/setting",
          "style": {
            "navigationBarTitleText": "设置"
          }
        }
      ]
    }
  ],
  
  //  分包预下载规则
  "preloadRule": {
  	// 在我的页面进入会员分包模块，预下载
    "pages/mine/mine": {
      // 在指定网络下预下载，可选值为：all（不限网络）、wifi（仅wifi下预下载）
      "network": "all",
      //  进入页面后预下载分包的 root 或 name。__APP__ 表示主包。
      "packages": ["member"]
    }
  }

路由分包跳转

uni.navigateTo({ url: '/member/setting/setting' });

环境变量

const DOMAIN = {
  development: 'http://127.0.0.1:3000',
  test: '',
  production: '',
};

let BASE_URL = '';

// #ifdef H5
if (process.env.NODE_ENV === 'development') {
  BASE_URL = DOMAIN.development;
} else if (process.env.NODE_ENV === 'production') {
  BASE_URL = DOMAIN.production;
}
// #endif

// #ifdef MP-WEIXIN
const envVersion = uni.getAccountInfoSync()?.miniProgram?.envVersion;
if (envVersion === 'develop') {
  BASE_URL = DOMAIN.development;
} else if (envVersion === 'trial') {
  BASE_URL = DOMAIN.production;
} else if (envVersion === 'release') {
  BASE_URL = DOMAIN.production;
}
// #endif

使用 pinia

pnpm add [email protected]

src/main.ts

import { createSSRApp } from "vue";
import * as Pinia from "pinia";

export function createApp() {
	const app = createSSRApp(App);
	app.use(Pinia.createPinia());
	return {
		app,
		Pinia, // 此处必须将 Pinia 返回
	};
}

src/stores/counter.ts

import { defineStore } from "pinia";

export const useCounterStore = defineStore("counter", {
	state: () => {
		return { count: 0 };
	},
	// 也可以这样定义
	// state: () => ({ count: 0 })
	actions: {
		increment() {
			this.count++;
		},
	},
});

使用

import { useCounterStore } from '@/stores/counter' 
const counter = useCounterStore()

pinia 持久化

• 安装

pnpm i pinia-plugin-persistedstate

• 配置

const pinia = Pinia.createPinia();
pinia.use(piniaPluginPersistedstate);

• 使用

import { defineStore } from "pinia";

export const useCounterStore = defineStore("counter", {
	state: () => {
		return { count: 0 };
	},

	persist: {
		// 改为 uni 写法
		storage: {
			getItem: (key) => {
				return uni.getStorageSync(key);
			},
			setItem: (key, value) => uni.setStorageSync(key, value),
		},
	},
});

crypto-js

报错 Native crypto module could not be used to get secure random number.

下载指定版本

pnpm add [email protected]

import CryptoJS from 'crypto-js';

const CRYPTO_SECRET = '__abc__';

/**
 * 加密数据
 * @param data - 数据
 */
export function encrypt(data: any) {
  const json = JSON.stringify(data);
  return CryptoJS.AES.encrypt(json, CRYPTO_SECRET).toString();
}

/**
 * 解密数据
 * @param cipherText - 密文
 */
export function decrypt(cipherText: string) {
  const bytes = CryptoJS.AES.decrypt(cipherText, CRYPTO_SECRET);
  const originalText = bytes.toString(CryptoJS.enc.Utf8);
  if (originalText) {
    return JSON.parse(originalText);
  }
  return null;
}

使用 unocss

兼容小程序 unocss-preset-weapp

 pnpm add unocss unocss-preset-weapp -D

vite.config.ts

import { defineConfig } from 'vite'
import uni from '@dcloudio/vite-plugin-uni'
import Unocss from 'unocss/vite'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    uni(),
    // https://github.com/antfu/unocss
    Unocss(),
  ],
})

uno.config.ts

import presetWeapp from 'unocss-preset-weapp';
import { extractorAttributify, transformerClass } from 'unocss-preset-weapp/transformer';

const { presetWeappAttributify, transformerAttributify } = extractorAttributify();
export default {
  presets: [
    // https://github.com/MellowCo/unocss-preset-weapp
    presetWeapp(),
    // attributify autocomplete
    presetWeappAttributify(),
  ],
  shortcuts: [
    {
      'border-base': 'border border-gray-500_10',
      center: 'flex justify-center items-center',
    },
  ],
  theme: {
    colors: {
      primary: '#186ffc',
    },
  },

  transformers: [
    // https://github.com/MellowCo/unocss-preset-weapp/tree/main/src/transformer/transformerAttributify
    transformerAttributify(),

    // https://github.com/MellowCo/unocss-preset-weapp/tree/main/src/transformer/transformerClass
    transformerClass(),
  ],
};

main.ts

import 'uno.css'
