最近有小夥伴問道如何在vue-cli項目中引入第三方插件或者庫,例如若是想在項目中使用jQuery中的Ajax請求數據呢?或者我想使用Bootstrap框架呢?等等這些問題,本篇博客將帶你學習如何引入第三方插件或者庫(僅僅只是一部分,若是沒有您想要的能夠自行百度),那麼一塊兒來看看吧!css
學會vue-cli項目中引入jQueryhtml
學會vue-cli項目中引入Bootstrap前端
首先咱們須要引入的是jQuey這個庫,畢竟做爲一名前端開發人員,咱們常用jQuey中的ajax請求數據,可是學完本篇博客你能夠使用另外一種方法請求數據,就是下文提到的axios,這個相對於jQuey中的ajax來講是相對好用的。vue
項目根目錄下找到package.json 添加node
"bootstrap": "^3.3.6", "jquery": "^2.1.4",
版本能夠根據本身的須要修改jquery
安裝命令webpack
cnpm install npm install
安裝完成以後咱們去node_modules查看是否安裝成功,安裝成功以後的結果ios
在main.js 導入 (注意導入是node_modules下的路徑能夠點進去查看具體位置)min是壓縮後文件建議導入這個web
import 'jquery/dist/jquery.min.js' import 'bootstrap/dist/css/bootstrap.min.css' import 'bootstrap/dist/js/bootstrap.min.js'
main.jsajax
// 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: '' })
使用這種方法引入
此時jQuery並未依賴成功,將提示錯誤:
需在build/webpack.base.conf.js中增長插件配置
const webpack = require('webpack')
配置中添加
plugins: [ new webpack.ProvidePlugin({ $: "jquery", jQuery: "jquery", "windows.jQuery": "jquery" }) ],
build下webpack.base.conf.js的完整結果
'use strict' const path = require('path') const utils = require('./utils') const config = require('../config') const vueLoaderConfig = require('./vue-loader.conf') const webpack =require('webpack') function resolve (dir) { return path.join(__dirname, '..', dir) } module.exports = { context: path.resolve(__dirname, '../'), entry: { app: './src/main.js' }, output: { path: config.build.assetsRoot, filename: '[name].js', publicPath: process.env.NODE_ENV === 'production' ? config.build.assetsPublicPath : config.dev.assetsPublicPath }, resolve: { extensions: ['.js', '.vue', '.json'], alias: { 'vue$': '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' } }
Bootstrap資料

配置好以後咱們就直接使用jQuey和Bootstrap
本身能夠新建一個組件中使用jQuery相關方法和Bootstrap相關資源
IndexComponent.vue
<template> <div> <h1>你好</h1> <button @click="changeMsg">改變消息</button> <ul class="nav nav-tabs"> <li role="presentation" class="active"><a href="/">首頁</a></li> <li role="presentation"><a href="#/a">組件A</a></li> <li role="presentation"><a href="#/b">組件B</a></li> <li role="presentation"><a href="#/c">組件C</a></li> </ul> </div> </template> <script> export default { name: "IndexComponent", data(){ return{ } }, methods:{ changeMsg(){ $('h1').text('我好') } } } </script> <style scoped> </style>
結果:
