# 前言 #

最近有小伙伴问道如何在vue-cli项目中引入第三方插件或者库，例如如果想在项目中使用jQuery中的Ajax请求数据呢？或者我想使用Bootstrap框架呢？等等这些问题，本篇博客将带你学习如何引入第三方插件或者库(仅仅只是一部分，如果没有您想要的可以自行百度)，那么一起来看看吧！

# vue-cli项目中引入jQuery和Bootstrap #

首先我们需要引入的是jQuey这个库，毕竟作为一名前端开发人员，我们经常使用jQuey中的ajax请求数据,但是学完本篇博客你可以使用另一种方法请求数据，就是下文提到的axios，这个相对于jQuey中的ajax来说是相对好用的。

#### (1)添加依赖并安装依赖 ####

项目根目录下找到package.json 添加

"bootstrap": "^3.3.6",
    "jquery": "^2.1.4",

版本可以根据自己的需要修改  
安装命令

cnpm install
    npm install

安装完成之后我们去node\_modules查看是否安装成功，安装成功之后的结果

#### (2)导入jQuey和Bootstrap ####

在main.js 导入 （注意导入是node\_modules下的路径可以点进去查看具体位置）min是压缩后文件建议导入这个

import 'jquery/dist/jquery.min.js'
    import 'bootstrap/dist/css/bootstrap.min.css'
    import 'bootstrap/dist/js/bootstrap.min.js'

main.js

// The Vue build version to load with the `import` command
    // (runtime-only or standalone) has been set in webpack.base.conf with an alias.
    import Vue from 'vue'
    import Vuex from 'vuex'
    import store from './store/index'
    // import router from './router'
    // import router from './router/hello'
    // import  router from './router/test'
    // import  router from './router/common'
    // import router from './router/one'
    import router from './router/two'
    import 'jquery/dist/jquery.min'
    import 'bootstrap/dist/js/bootstrap.min'
    import 'bootstrap/dist/css/bootstrap.min.css'
    Vue.config.productionTip = false
    Vue.use(Vuex)
    /* eslint-disable no-new */
    new Vue({
      el: '#app',
      router,
      store,
      components: {},
      template: ''
    })

使用这种方法引入

#### (3)使用内置插件ProvidePlugin自动加载模块 ####

此时jQuery并未依赖成功，将提示错误:

需在build/webpack.base.conf.js中增加插件配置

const webpack = require('webpack')

配置中添加

plugins: [
      new webpack.ProvidePlugin({
        $: "jquery",
        jQuery: "jquery",
        "windows.jQuery": "jquery"
      })
    ],

build下webpack.base.conf.js的完整结果

'use strict'
    const path = require('path')
    const utils = require('./utils')
    const config = require('../config')
    const vueLoaderConfig = require('./vue-loader.conf')
    const webpack =require('webpack')
    function resolve (dir) {
      return path.join(__dirname, '..', dir)
    }
    
    
    
    module.exports = {
      context: path.resolve(__dirname, '../'),
      entry: {
        app: './src/main.js'
      },
      output: {
        path: config.build.assetsRoot,
        filename: '[name].js',
        publicPath: process.env.NODE_ENV === 'production'
          ? config.build.assetsPublicPath
          : config.dev.assetsPublicPath
      },
      resolve: {
        extensions: ['.js', '.vue', '.json'],
        alias: {
          'vue$': 'vue/dist/vue.esm.js',
          '@': resolve('src'),
        }
      },
      module: {
        rules: [
          {
            test: /\.vue$/,
            loader: 'vue-loader',
            options: vueLoaderConfig
          },
          {
            test: /\.js$/,
            loader: 'babel-loader',
            include: [resolve('src'), resolve('test'), resolve('node_modules/webpack-dev-server/client')]
          },
          {
            test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
            loader: 'url-loader',
            options: {
              limit: 10000,
              name: utils.assetsPath('img/[name].[hash:7].[ext]')
            }
          },
          {
            test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,
            loader: 'url-loader',
            options: {
              limit: 10000,
              name: utils.assetsPath('media/[name].[hash:7].[ext]')
            }
          },
          {
            test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
            loader: 'url-loader',
            options: {
              limit: 10000,
              name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
            }
          }
        ]
      },
      plugins: [
        new webpack.ProvidePlugin({
          $: "jquery",
          jQuery: "jquery",
          "windows.jQuery": "jquery"
        })
      ],
      node: {
        // prevent webpack from injecting useless setImmediate polyfill because Vue
        // source contains it (although only uses it if it's native).
        setImmediate: false,
        // prevent webpack from injecting mocks to Node native modules
        // that does not make sense for the client
        dgram: 'empty',
        fs: 'empty',
        net: 'empty',
        tls: 'empty',
        child_process: 'empty'
      }
    }

#### (4)使用jQuery与Bootstrap ####

Bootstrap资料  
Bootstrap中文网：[https://www.bootcss.com/][https_www.bootcss.com]  
菜鸟教程：[https://www.runoob.com/bootstrap/bootstrap-tutorial.html][https_www.runoob.com_bootstrap_bootstrap-tutorial.html]  
配置好之后我们就直接使用jQuey和Bootstrap  
自己可以新建一个组件中使用jQuery相关方法和Bootstrap相关资源  
IndexComponent.vue

<template>
        <div>
          <h1>你好</h1>
          <button @click="changeMsg">改变消息</button>
          <ul class="nav nav-tabs">
            <li role="presentation" class="active"><a href="/">首页</a></li>
            <li role="presentation"><a href="#/a">组件A</a></li>
            <li role="presentation"><a href="#/b">组件B</a></li>
            <li role="presentation"><a href="#/c">组件C</a></li>
          </ul>
        </div>
    </template>
    
    <script>
        export default {
            name: "IndexComponent",
            data(){
              return{
    
              }
            },
            methods:{
              changeMsg(){
                $('h1').text('我好')
              }
            }
    
        }
    </script>
    
    <style scoped>
    
    </style>

结果：
