Adding bootstrap to Vue CLI project

Question

I'm new to Vue and webpack in general and I'm having a hard time figuring out how to import things.

I created a fresh Vue project through vue init I added bootstrap 4 with yarn add [email protected]

In main.js I try to import bootstrap and jquery:

import Vue from 'vue'; import jQuery from 'jquery'; import bootstrap from 'bootstrap'; import App from './App'; import router from './router'; 

But I get:

Uncaught Error: Bootstrap's JavaScript requires jQuery. jQuery must be included before Bootstrap's JavaScript.

window.jQuery = window.$ = $; does not work

Finally, where and how do I load the Sass such that it's available to the whole app?

I was having the same issue and this is what I ended up with however, I didn't use Bootstrap alpha since the beta has since been released.

1. Install Bootstrap along with its dependencies, jQuery and Popper.js:

npm install [email protected] popper.js jquery --save-dev 

2. Edit your /build/webpack.dev.conf.js file to add a plugin for jQuery and Popper.js to deal with dependencies (you can read more about that in the Bootstrap docs):

plugins: [     // ...     new webpack.ProvidePlugin({         $: 'jquery',         jQuery: 'jquery',         'window.jQuery': 'jquery',         Popper: ['popper.js', 'default'],         // In case you imported plugins individually, you must also require them here:         Util: "exports-loader?Util!bootstrap/js/dist/util",         Dropdown: "exports-loader?Dropdown!bootstrap/js/dist/dropdown",         // ...     })     // ... ] 

3. Edit /src/main.js to import Bootstrap into the app's entry point:

import Vue from 'vue' import App from './App' import router from './router' import 'bootstrap' // ← 

4. Edit the App.vue' file's <style> portion to import Bootsrap into your app's root css:

<template>   <div id="app">     <img src="./assets/logo.png">     <router-view></router-view>   </div> </template>  <script> export default {   name: 'app' } </script>  <style> #app {   font-family: 'Avenir', Helvetica, Arial, sans-serif;   -webkit-font-smoothing: antialiased;   -moz-osx-font-smoothing: grayscale;   text-align: center;   color: #2c3e50;   margin-top: 60px; }  @import'~bootstrap/dist/css/bootstrap.css' </style> 

5. Run your Vue app from the CLI

npm start

I had to add the @import rule after the #app selector, otherwise the scoped styling would be canceled out by the Bootstrap import. I think there is a better way to do this so I will update my answer once I figure it out.

You don't want to do any kind of adjustment in webpack.config.js like adding jQuery global in plugin array. Once you installed all bootstrap dependencies like jQuery and popper than just import them in app.vue or main.js (you can import separately in each component if you wish)

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

thats it ..
