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！
学会vue-cli项目中引入jQuery
学会vue-cli项目中引入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。
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
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
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‘ } }

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：
