# 使用 npm 安装 CLI
$ npm install -g @tarojs/cli

查看 Taro 全部版本信息​

可以使用 npm info 查看 Taro 版本信息，在这里你可以看到当前最新版本

npm info @tarojs/cli

项目初始化​

使用命令创建模板项目：

taro init 项目名

taro init myApp

微信小程序自定义 TabBar

先安装 cnpm install pinia 以便解决 小程序的 页面首次加载

在 app.config.js 中设置

export default defineAppConfig({pages: ['pages/myPage01/index','pages/myPage02/index',],window: {backgroundTextStyle: 'light',navigationBarBackgroundColor: '#fff',navigationBarTitleText: 'WeChat',navigationBarTextStyle: 'black'},tabBar: {custom: true,color: '#000000',selectedColor: '#000000',backgroundColor: '#000000',list: [{pagePath: 'pages/myPage01/index',text: '页面01',},{pagePath: 'pages/myPage02/index',text: '页面02',},],}
})

在 src 目录下 pages 文件夹，在里面新建页面 

在 src 目录下添加 custom-tab-bar 文件夹，在里面书写底部导航栏组件

在 src 目录下添加 store 文件夹，在里面写 index.js

在 src 目录下添加 assets 文件夹，在里面添加 pic 和 tabbarIcon 

custom-tab-bar 的 index.js

<template><view class="custom-tab-bar" style="display: flex; justify-content: space-around; align-items: center; padding: 10rpx 24rpx; background: #fff;"><view v-for="(item, index) in tabList" @click="handleClick(item, index)"><view style="width: 96rpx; height: 64rpx;"><img style="width: 100%; height: 100%;" :src=" current === index ? item.activeImg : item.img" alt=""></view><view style="font-size: 24rpx; width: 100%; text-align: center;">{{ item.title }}</view></view></view>
</template><script setup>
import Taro from '@tarojs/taro'
import { useTabBarStore } from "../store/index";
import { ref, reactive, computed } from 'vue'const tabBarStore = useTabBarStore();const current = computed(() => tabBarStore.getSelected)const tabList = reactive([{title: '首页',pagePath: '/pages/myPage01/index',img: require('../assets/tabbarIcon/myPage01.png'),activeImg: require('../assets/tabbarIcon/myPage01Active.png')},{title: '我的',pagePath: '/pages/myPage02/index',img: require('../assets/tabbarIcon/myPage02.png'),activeImg: require('../assets/tabbarIcon/myPage02Active.png')},
])
const handleClick = (item, index) => {tabBarStore.setSelected(index);Taro.switchTab({ url: item.pagePath })
}
</script><style lang="scss" scoped></style>

store 的 index.js

import { defineStore } from "pinia";export const useTabBarStore = defineStore("tabBar", {state: () => {return { selected: 0 };},getters: {getSelected(state) {return state.selected;},},actions: {setSelected(value) {this.selected = value;},},
});

在 app.js 引入 pinia 

import { createApp } from 'vue'
import './app.scss'
import { createPinia } from "pinia";const App = createApp({onShow (options) {},// 入口组件不需要实现 render 方法，即使实现了也会被 taro 所覆盖
})App.use(createPinia())export default App

设置分享功能 在 app.js 写入

// app.js
import Taro from "@tarojs/taro";
// 分享的时候 wx.getStorageSync("sharePageUrl") 获取分享页面，在每个要分享的页面  进行设置缓存中的 sharePageUrl
/*** 全局分享配置，页面无需开启分享* 使用隐式页面函数进行页面分享配置* 使用隐式路由获取当前页面路由，并根据路由来进行全局分享、自定义分享*/
!(function () {//获取页面配置并进行页面分享配置var PageTmp = Page;Page = function (pageConfig) {Taro.showShareMenu({withShareTicket: true,});//1. 获取当前页面路由let routerUrl = "";wx.onAppRoute(function (res) {//app.js中需要在隐式路由中才能用getCurrentPages（）获取到页面路由let pages = getCurrentPages(),view = pages[pages.length - 1];if (view) {routerUrl = view.route;}});//2. 全局开启分享配置pageConfig = Object.assign({onShareAppMessage: function () {//根据不同路由设置不同分享内容（微信小程序分享自带参数，如非特例，不需配置分享路径）let shareInfo = {};let noGlobalSharePages = ["index/index"];//全局分享配置，如部分页面需要页面默认分享或自定义分享可以单独判断处理if (!routerUrl.includes(noGlobalSharePages)) {shareInfo = {title: "小鑫向上",imageUrl: wx.getStorageSync("shareUrl"),};}return shareInfo;},onShareTimeline: function (res) {console.log(res)console.log(routerUrl)let shareData = {title: "小鑫向上",path: wx.getStorageSync("sharePageUrl"), // 分享的路径// imageUrl： '',  // 分享的图片链接};return shareData;},},pageConfig);// 配置页面模板PageTmp(pageConfig);};
})();

封装API接口

在 src 下 新建 api 文件夹 下 继续创建 文件

baseUrl.js

const getBaseUrl = (url) => {let BASE_URL = "";if (process.env.NODE_ENV === "development") {// 开发环境 - 根据请求不同返回不同的BASE_URL// BASE_URL = "http://pig-gateway:9999";// BASE_URL = "http://127.0.0.1:3000"BASE_URL = "http://123.207.67.156:8889";} else {// 生产环境// BASE_URL = "http://127.0.0.1:3000"BASE_URL = "http://123.207.67.156:8889";}return BASE_URL;
};export default getBaseUrl;

http.js

import Taro from "@tarojs/taro";

}export default new httpRequest();

};// Taro 提供了两个内置拦截器
// logInterceptor - 用于打印请求的相关信息
// timeoutInterceptor - 在请求超时时抛出错误。
const interceptors = [customInterceptor];export default interceptors;
