Electron-vue: Static assets not found

[ChucKN0risK]

Hi everyone!

I am used to Gulp and I’m totally new in Webpack and Vue.js and I’m lost under all the necessary configuration 😕

I can’t manage to use assets like images of fonts in my app. Whether I call them in a .vue component or inside my .scss files.

Here’s my project structure:

Here’s my webpack.renderer.config.js:

'use strict'

process.env.BABEL_ENV = 'renderer'

const path = require('path')
const { dependencies } = require('../package.json')
const webpack = require('webpack')

const BabiliWebpackPlugin = require('babili-webpack-plugin')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')

/**
 * List of node_modules to include in webpack bundle
 *
 * Required for specific packages like Vue UI libraries
 * that provide pure *.vue files that need compiling
 * https://simulatedgreg.gitbooks.io/electron-vue/content/en/webpack-configurations.html#white-listing-externals

let whiteListedModules = ['vue']

let rendererConfig = {
  devtool: '#cheap-module-eval-source-map',
  entry: {
    renderer: path.join(__dirname, '../src/renderer/main.js')
  },
  externals: [
    ...Object.keys(dependencies || {}).filter(d => !whiteListedModules.includes(d))

How I load images and fonts in my .scss files:

Images:

#wrapper {
  background-image: url('~@/assets/img/photo.jpeg');
  font-family: var(--RobotoRegular);
}

Fonts:

@font-face {
  font-family: "RobotoRegular";
  src: url("~@/assets/fonts/Roboto-Regular.woff2") format("woff2"),  
         url("~@/assets/fonts/Roboto-Regular.woff") format("woff"),
         url("~@/assets/fonts/Roboto-Regular.otf") format("opentype");  
}

How I load my images inside a vue component:

<img id="img" src="~@/assets/img/photo.jpeg" alt="img-test">

Which seems to be OK with Webpack:

However files are not found by the server and I don’t know why 😕

Thanks in advance 😃

Development environment:

• Node version: 9.5.0
• NPM version: 5.6.0
• Vue CLI version: 3.0.0-alpha.10
• OS : MacOS 10.12.6

Well all I had to do was to specify a publicPath in the output.

output: {
    publicPath: '/',
    filename: 'assets/scripts/[name].js',
    libraryTarget: 'commonjs2',
    path: path.join(__dirname, '../dist/electron')
},

This question on StackOverflow helped me understand: https://stackoverflow.com/questions/28846814/what-does-publicpath-in-webpack-do
