详解vue-cli快速构建项目以及引入bootstrap、jq

vue-cli脚手架工具快速构建项目架构：

。。首先默认了有已经安装了node。。。

npm install -g vue-cli                   全局安装vue-cli

vue init webpack cnm                  生成项目名为cnm的的项目模板，cnm自定义

npm install                                   到cnm文件夹中打开Git bash或者命令窗口初始化安装依赖

此时文件夹目录应该是这样

然后输入npm run dev。。不出意外浏览器会自动弹出一个欢迎页面，如果不自动弹出就打开http://localhost:8080

到这里就可以在对应的文件中修改代码开发项目了。。。但是如果要引入一些插件或者框架怎么办呢？

引入jq：

输入 npm install jQuery --save-dev      用npm下载jq依赖、

找到build文件夹下的webpack.base.conf.js文件打开，修改配置：

1、加入webpack对象：

var webpack=require('webpack');

2、在module.exports里面加入：

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

3、在入口文件main.js中加入

import $ from 'jquery'

全局引入jq

引入bootstrap：

1、修改webpack.base.conf.js文件：

alias: {
   'vue$': 'vue/dist/vue.esm.js',
   '@': resolve('src'),
   'assets': path.resolve(__dirname, '../src/assets'),
   'jquery': "jquery/src/jquery"
  }

2、在入口文件main.js中加入：

import './assets/css/bootstrap.min.css'
import './assets/js/bootstrap.min' 

3、在assets文件目录中拷贝bootstrap各种文件

试试bootstrap引入成功没：

打开hello.vue文件

替换组件模板

<template>
 <nav class="navbar navbar-default" role="navigation">
  <div class="container-fluid">
   <!-- Brand and toggle get grouped for better mobile display -->
   <div class="navbar-header">
    <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
