vue2 项目实例 项目初始化（一）

1、创建 Vue2 项目

cd 项目名称  # 例如：cd my-vue2-project
npm run serve  # 启动开发服务器

2、项目目录结构（核心文件）

my-vue2-project/
├── public/              # 静态资源（不会被 Webpack 处理）
├── src/
│   ├── assets/          # 静态资源（会被 Webpack 处理）
│   ├── components/      # 公共组件
│   ├── router/          # 路由配置（若勾选了 Router）
│   ├── store/           # 状态管理（若勾选了 Vuex）
│   ├── views/           # 页面组件（若勾选了 Router）
│   ├── App.vue          # 根组件
│   └── main.js          # 入口文件
├── .eslintrc.js         # ESLint 配置
├── babel.config.js      # Babel 配置
├── package.json         # 项目依赖和脚本
└── vue.config.js        # Vue 项目自定义配置（可手动创建）

 

3、安装依赖 

# 安装UI组件库
npm i element-ui -S

# 安装HTTP请求库
npm i axios -S

# 安装工具库
npm i lodash -S

# 安装开发依赖
npm i compression-webpack-plugin clean-webpack-plugin -D

#Vue2 需搭配 vue-router@3.x（4.x 仅支持 Vue3）

npm install vue-router@3.x --save

#Vue2 需搭配 vuex@3.x（4.x 仅支持 Vue3）

npm install vuex@3.x --save

 

4、vue.config.js配置

const path = require('path')

module.exports = {
  chainWebpack: (config) => {
    // 配置别名
    config.resolve.alias
      .set('@', path.resolve(__dirname, 'src'))
      .set('@api', path.resolve(__dirname, 'src/api'))
      .set('@assets', path.resolve(__dirname, 'src/assets'))
      .set('@components', path.resolve(__dirname, 'src/components'))
      .set('@views', path.resolve(__dirname, 'src/views'))

  }
}

 

5、router  模式需要注意不要 # history模式 ，nginx配置有相关文章

}

export default router

 

6、main.js配置

import Vue from 'vue'
import App from './App.vue'
import router from './router'

Vue.config.productionTip = false

new Vue({
  router,
  render: (h) => h(App)
}).$mount('#app')
