基本概念

通过在webpack.config.js这个文件中添加module rules进行如下代码：

这里分别是加载vue，以及css，和styl样式和图片

styl用于css预处理，模块化编写css

这里还要说下图片，这里的options为其他的选项，比如：

test: /\.(gif|jpg|jpeg|png|svg)$/,
    use: [
        {
            loader: 'url-loader',
            options:{
                limit: 1024,
                name: '[name] aaa.[ext]'
            }
        }
    ]

这里限制图片大小为1024，大了的用base64压缩，把名字打包为[name] aaa.[ext]

如下添加的图片和css、styl在bundle.js中都能找到

他会将其中的内容都放到bundle.js中

 

 

代码与实例

文件结构如下：

源码如下：

test-stylus.styl

body
    font-size: 20px

test.css

body{
    color: red;
    background-image: url('../images/gen.svg')
}

app.vue

<template>
    <div id="test">{{text}}</div>
</template>

<script>
export default {
    data(){
        return {
            text: "abc"
        }
    }
}
</script>

<style>
#test{
    color: red;
}
</style>

index.js

import Vue from 'vue'
import App from './app.vue'

import './asserts/images/bg.jpg'
import './asserts/styles/test.css'
import './asserts/styles/test-stylus.styl'

const root = document.createElement('div')
document.body.appendChild(root)

new Vue({
    render: (h) => h(App)
}).$mount(root)
