首先把package.json贴出来，这里很多插件存在版本区别，因此要特别注意版本，不是所有的安装最新的都行

{

  "name": "life_manager",

  "version": "1.0.0",

  "description": "",

  "main": "index.js",

  "scripts": {

    "test": "echo \"Error: no test specified\" && exit 1",

    "dev": "webpack-dev-server --contentBase src --hot"

  },

  "keywords": [],

  "author": "",

  "license": "ISC",

  "dependencies": {

    "jquery": "^3.3.1",

    "vue": "^2.5.17",

    "vue-router": "^2.8.1",

    "webpack": "^3.10.0"

  },

  "devDependencies": {

    "babel-core": "^6.26.3",

    "babel-loader": "^7.1.5",

    "babel-plugin-transform-runtime": "^6.23.0",

    "babel-preset-env": "^1.7.0",

    "babel-preset-stage-0": "^6.24.1",

    "css-loader": "^1.0.0",

    "file-loader": "^2.0.0",

    "html-webpack-plugin": "^3.2.0",

    "style-loader": "^0.23.0",

    "url-loader": "^1.1.1",

    "vue-loader": "^13.7.3",

    "vue-template-compiler": "^2.5.17",

    "webpack-dev-server": "^2.11.3"

  }

}

其次是webpack.config.js文件

const path = require("path");

const htmlWebpack = require("html-webpack-plugin");//首先是这里要引用

module.exports = {

    entry: path.join(__dirname, './src/main.js'),//指定入口文件

    output: {

        path: path.join(__dirname, './dist'),//指定输出的文件路径

        filename: 'bundle.js'//指定输出的文件名

    },

    plugins: [

        new htmlWebpack({//其次是这里要实例化

            template: path.join(__dirname, './src/index.html'),

            filename: 'index.html'

        })

    ],

    module: {//配置所有的第三方模块加载器

        rules: [

            {

                //配置处理.css文件的第三方loader规则

                test: /\.css$/,

                use: ['style-loader', 'css-loader']

            },

            { test: /\.(jpg|png|gif|bmp|jpeg)$/, use: 'url-loader?limit=2000&name=[hash:8]-[name].[ext]' },

            { test: /\.js$/, use: 'babel-loader', exclude: /node_modules/ },

            { test: /\.vue$/, use: 'vue-loader' }

        ]

    },

    resolve:{

        alias:{

            // "vue$":"vue/dist/vue.js"

        }

    }

}

在看看项目结构

学了vue和webpack的笔记

index.html代码如下：

<!DOCTYPE html>

<html>

<head>

    <meta charset="utf-8" />

    <meta http-equiv="X-UA-Compatible" content="IE=edge">

    <title>Page Title</title>

    <meta name="viewport" content="width=device-width, initial-scale=1">

    <script src="./bundle.js"></script>

</head>

<body>

    <div id="app"></div>

</body>

</html>

main.js代码如下：

import $ from 'jquery'

import './css/index.css'

import Vue from 'vue'

import VueRouter from 'vue-router'

import user from './vue/user.vue'

import role from './vue/role.vue'

import app from './vue/app.vue'

Vue.use(VueRouter);

var router = new VueRouter({

    routes: [

        { path: "/user", component: user },

        { path: "/role", component: role },

    ]

});

var v1 = new Vue({

    el: "#app",

    render: c => c(app),

    router

})

app.vue代码如下：

<template>

    <div>

        <h2>收支管理系统</h2>

        <router-link to="/user">用户管理</router-link>

        <router-link to="/role">角色管理</router-link>

        <router-view></router-view>

    </div>

</template>

<script>

export default {

}

</script>

.babelrc内容如下：

{

    "presets": [

        "env","stage-0"

    ],

    "plugins": [

        "transform-runtime"

    ]

}

常用技术点说一下

  • nrm 的使用，用于设置镜像的地址
  • webpack-dev-server 用于开发过程，热部署，不用每次重启
  • html-webpack-plugin 用于将html加载到内存中，而非物理磁盘
  • style-loader css-loader 用于样式表的解析
  • url-loader file-loader 用于样式中存在图片、字体等url地址的处理
  • babel-core 用于ES6高级语法解析
  • vue-loader vue-template-compiler 用于解析独立的vue文件
