Vue Cli Webpack background url path issue

Question

Using vue cli.

For some reason, SOME of my images, if I refer to them directly in the scss and don't bind them dynamically to my vue object have issues with relative paths.

Say I have a vue template with a div called box. Box has a background url of this:

.box{ background: url('../img/box.jpg')

That works locally just fine when I run npm run dev. But when I run build, it doesn't work. 404 error. I have also tried doing this:

.box{
background: url('~../img/box.jpg')

And that didn't work.

So there's this:

webpack css-loader not finding images within url() reference in an external stylesheet

And when I change this in webpack.config:

output: {
    path: path.resolve(__dirname, './dist'),
    publicPath: '/dist/',
    filename: 'build.js'
  },

To:

output: {
    path: path.resolve(__dirname, './dist'),
    publicPath: './dist/',
    filename: 'build.js'
  },

It'll create Chunk Images in my webpack build with hashes for cacheing. And just for those specific images that aren't bound in the vue object.

And then I have to drag those images over to the root dist folder....rather than what I want to do which is keep them in an img folder relative to the html file ( html file is simply ):

<html lang="en">
  <head>

    <meta charset="utf-8">
    <title>vue</title>

  </head>
  <body>
    <script src="https://code.jquery.com/jquery-2.2.0.min.js"></script>


    <app></app>
    <script src="dist/build.js"></script>
  </body>
</html>

Question is, do I have to bind every single vue img from the data...or can't I just directly refer to a image if I know it's not going to be changed.

Or is there some setting in my sass loader/webpack that i'm missing.

Here's my webpack config:

var path = require('path')
var webpack = require('webpack')

module.exports = {
  entry: './src/main.js',
  output: {
    path: path.resolve(__dirname, './dist'),
    publicPath: './dist/',
    filename: 'build.js'
  },
  resolveLoader: {
    root: path.join(__dirname, 'node_modules'),
  },
  vue: {
    html: {
      root: path.resolve(__dirname, './dist')
    }
  },
  module: {
    loaders: [
      {
        test: /\.vue$/,
        loader: 'vue'
      },
      {
        test: /\.js$/,
        loader: 'babel',
        exclude: /node_modules/
      },
      {
        test: /\.json$/,
        loader: 'json'
      },
      {
        test: /\.html$/,
        loader: 'vue-html'
      },
      {
        test: /\.scss$/,
        loaders: ["style", "css", "sass"]
      },
      {
        test: /\.(png|jpg|gif|svg)$/,
        loader: 'url',
        query: {
          limit: 10000,
          name: '[name].[ext]?[hash]'
        }
      }
    ]
  },
  devServer: {
    historyApiFallback: true,
    noInfo: true
  },
  devtool: '#eval-source-map'
}

if (process.env.NODE_ENV === 'production') {
  module.exports.devtool = '#source-map'
  // http://vue-loader.vuejs.org/en/workflow/production.html
  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"production"'
      }
    }),
    new webpack.optimize.UglifyJsPlugin({
      compress: {
        warnings: false
      }
    }),
    new webpack.optimize.OccurenceOrderPlugin()
  ])
}

Try the url prefix of '~@/'

background-image: url('~@/assets/box.jpg');

I managed to replicate your problem with the following steps:

Assuming the following directory:

root/
  dist/
  src/
    assets/
      |--box.jpg
    components/
      |--home.vue

And home.vue:

<template>
  <div class="foo">

  </div>
</template>

<script>
  export default {
  }
</script> 

<style>
  .foo {
    background: url('../assets/box.jpg')
  }
</style>

After building the application and save the files in the dist folder, everything works if I serve the built files using this command inside dist folder (I use lite-server for simplicity):

lite-server index.html

However, if I go back to the root folder and try to do the same:

lite-server dist/index.html

I will encounter the same problem as you.

How I usually get around this is by importing the image first and then using it with inline style:

<template>
  <div v-bind:style= "{ 'background-image': 'url(' + box + ')' }">
    Placeholder
  </div>
</template>

<script>
  // @ is an alias to /src
  import box from '@/assets/box.jpg';

  export default {
    data() {
      return { box };
    }
  }
</script>

depends on where your root set, you could try background: url('~/assets/img/box.jpg') or background: url('~/src/assets/img/box.jpg'),
one of them should work
