本文主要是介绍Vue2项目搭建：Vue2.7+Vite4+Pinia+TailwindCSS+Prettier+ESLint，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
目前 create-vue 和 Vite 都不提供 Vue2 项目的搭建，不想用 Vue CLI 和 webpack，于是就打算从 0 搭建一个工程化项目，支持组合式 API (Composition API) 写法，没有使用 TypeScript，有朋友需要的话我可以再完善一下。
- Node.js 16.x
- pnpm 8.x
初始化
mkdir vue2-vite
cd vue2-vite
pnpm init
安装依赖：
pnpm install vue@^2 vue-router@^3 pinia
pnpm install vite@^4 @vitejs/plugin-vue2 tailwindcss postcss autoprefixer prettier prettier-plugin-tailwindcss eslint@^8 eslint-config-prettier eslint-plugin-prettier eslint-plugin-vue -D
package.json：
{"name": "vue2-vite","version": "1.0.0","scripts": {"dev": "vite","build": "vite build","preview": "vite preview","lint": "eslint . --ext .vue,.js,.jsx,.cjs,.mjs --fix --ignore-path .gitignore","format": "prettier --write \"src/**/*.{vue,js,css,scss}\""},"keywords": [],"author": "","license": "ISC","devDependencies": {"@vitejs/plugin-vue2": "^2.3.1","autoprefixer": "^10.4.20","eslint": "^8.57.0","eslint-config-prettier": "^9.1.0","eslint-plugin-prettier": "^5.2.1","eslint-plugin-vue": "^9.27.0","postcss": "^8.4.41","prettier": "^3.3.3","prettier-plugin-tailwindcss": "^0.6.6","tailwindcss": "^3.4.10","vite": "^4.5.3"},"dependencies": {"pinia": "^2.2.2","vue": "^2.7.16","vue-router": "^3.6.5"}
}
Vite
新建 vite.config.js 文件：
import vue from '@vitejs/plugin-vue2'
import { fileURLToPath, URL } from 'node:url'export default {plugins: [vue()],resolve: {alias: {'@': fileURLToPath(new URL('./src', import.meta.url)),},},
}
Tailwind CSS
pnpm tailwindcss init -p
修改 tailwindcss.config.js 文件：
/** @type {import('tailwindcss').Config} */
export default {content: ["./index.html","./src/**/*.{js,ts,jsx,tsx,vue}",],theme: {extend: {},},plugins: [],
}
新建 src/assets/styles/index.css 文件：
@tailwind base;
@tailwind components;
@tailwind utilities;
Prettier
新建 prettier.config.mjs 文件：
/*** @see https://prettier.io/docs/en/configuration.html* @type {import("prettier").Config}*/
export default {semi: false,singleQuote: true,htmlWhitespaceSensitivity: 'ignore',plugins: ['prettier-plugin-tailwindcss'],
}
ESLint
新建 .eslintrc.cjs 文件：
/* eslint-env node */
module.exports = { root: true, extends: ['plugin:vue/recommended', 'eslint:recommended', 'prettier'], plugins: ['prettier'], rules: { 'vue/multi-word-component-names': 'off', },
}
Vue
新建 index.html文件：
<!doctype html>
<html lang="zh"><head><meta charset="UTF-8" /><link rel="icon" href="/favicon.ico"><metaname="viewport"content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"/><meta http-equiv="X-UA-Compatible" content="ie=edge" /><title>vue2-vite</title></head><body><div id="app"></div><script type="module" src="/src/main.js"></script></body>
</html>
新建入口文件 src/main.js：
import Vue from 'vue'
import { createPinia, PiniaVuePlugin } from 'pinia'import App from '@/App.vue'
import router from '@/router'
import '@/assets/styles/index.css'const pinia = createPinia()Vue.use(PiniaVuePlugin)new Vue({render: (h) => h(App),router,pinia,
}).$mount('#app')
新建 src/App.vue 文件：
<script setup></script><template><div><router-view /></div>
</template>
tips：如果是 WebStorm 编辑器，并且是通过 pnpm 安装的依赖，可能会遇到 router-view、router-link 标签无法识别的问题，可以展开 node_modules 文件夹，找到 vue-router，右键，将目标标记为 -> 不排除，就可以了。类似问题：https://youtrack.jetbrains.com/issue/WEB-56972/Vue-library-components-not-resolved-when-installed-with-pnpm
Vue Router
新建 src/router/index.js 文件：
import Vue from 'vue'
import Router from 'vue-router'Vue.use(Router)const routes = [{path: '/',name: 'home',component: () => import('@/views/Home.vue'),},
]const router = new Router({mode: 'history',routes,
})export default router
新建 src/views/Home.vue 文件：
<script setup></script><template><div>Home</div>
</template>
pinia
新建 src/store/counter.js：
import { computed, ref } from 'vue'
import { defineStore } from 'pinia' export const useCounterStore = defineStore('counter', () => { const count = ref(0) const doubleCount = computed(() => count.value * 2) function increment() { count.value++ } return { count, doubleCount, increment }
})
在 Vue 中使用：
<script setup>
import { useCounterStore } from '@/store/counter'const counterStore = useCounterStore()
</script><template><div><div>{{ counterStore.count }}</div><div>{{ counterStore.doubleCount }}</div><button @click="counterStore.increment">increment</button></div>
</template>
