Vue：在vue-cli中使用Bootstrap

一、安装jQuery

Bootstrap需要依赖jQuery，所以引用Bootstrap之前要先引用jQuery，使用下面的命令引用jQuery：

npm install jquery --save

注意：如果想查看npm上jquery有哪些版本，可以执行命令：

npm view jquery versions

二、引入Bootstrap

1、使用命令安装

可以使用下面的命令安装：

npm install bootstrap --save

2、下载Bootstrap文件

直接去Bootstrap下载bootstrap包，把下载好的文件放到src/assets目录下面：

三、配置使用jQuery

1、添加webpack

在build/webpack.base.conf.js文件的顶部添加下面的代码：

const webpack=require("webpack")

2、修改webpack.base.conf.js

在build/webpack.base.conf.js文件中，在整个配置对象的末尾增加plugins配置：

// 配置全局使用 jquery
plugins: [
    new webpack.ProvidePlugin({
    $: "jquery",
    jQuery: "jquery",
    jquery: "jquery",
    "window.jQuery": "jquery"
})]

build/webpack.base.conf.js完整代码如下：

\'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)
}

// const createLintingRule = () => ({
//   test: /\.(js|vue)$/,
//   loader: \'eslint-loader\',
//   enforce: \'pre\',
//   include: [resolve(\'src\'), resolve(\'test\')],
//   options: {
//     formatter: require(\'eslint-friendly-formatter\'),
//     emitWarning: !config.dev.showEslintErrorsInOverlay
//   }
// })

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$\': \'vue/dist/vue.esm.js\',
      \'@\': resolve(\'src\')
    }
  },
  module: {
    rules: [
      // 关闭eslint编码规范验证
      // ...(config.dev.useEslint ? [createLintingRule()] : []),
      {
        test: /\.vue$/,
        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]\')
        }
      }
    ]
  },
  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\'
  },
  // 配置全局使用 jquery
  plugins: [
    new webpack.ProvidePlugin({
    $: "jquery",
    jQuery: "jquery",
    jquery: "jquery",
    "window.jQuery": "jquery"
  })]
}

四、在main.js中引用

// 引入jQuery
import $ from \'jquery\'
// 引用bootstrap
import \'./assets/bootstrap-3.3.7-dist/css/bootstrap.css\'
import \'./assets/bootstrap-3.3.7-dist/js/bootstrap.js\'

五、测试

<template>
  <div>
      <p class="col-md-6">
         <button class="btn btn-primary">测试按钮</button>
      </p>
  </div>

</template>

<script>
export default {
  name:"test",
}
</script>

运行效果：
