So I am working on a simple card game, where i have like 40 images relate to the cards. I am using Vue Cli that already es with a simple webpack configuration.

So basicly I am saving all the images on the static folder like this:

When I build the project for production, generating the dist folder, it creates the images like this:

this is my webpack production file:

'use strict'

I'm assuming you used vuejs-templates/webpack, which does not include image optimization out of the box. You can easily add this (with imagemin-webpack-plugin) in your Webpack config:

1. Install ImageminWebpackPlugin with: npm i -D imagemin-webpack-plugin

2. In build/webpack.prod.conf.js, import the plugin, and configure it in plugins[] (after CopyWebpackPlugin):

   const ImageminPlugin = require('imagemin-webpack-plugin').default;
   
   const webpackConfig = merge(baseWebpackConfig, {
     plugins: [
       // ...
       new ImageminPlugin({
         test: /\.(jpe?g|png|gif|svg)$/i,
         /* other ImageMin configs */
       })
     ]
   }
   

Running ImageminWebpackPlugin after CopyWebpackPlugin ensures the copied images from static are run through ImageMin optimization.

GitHub repo demo

In the current version of Vue you can use a vue.config.js that looks like this:

const ImageminPlugin = require('imagemin-webpack-plugin').default;

module.exports = {
  configureWebpack: {
    plugins: [
      new ImageminPlugin({
        disable: process.env.NODE_ENV !== 'production',
      })
    ]
  }
}

This will enable Imagemin on production builds but skip on development builds.

You can have a try. It will help you minify images automaticlly without plicated algorithm configurations. It can also help you to encode(and inline) images (behave more flexible than url-loader).

https://github./GaoYYYang/image-optimize-loader

module.exports = {
  module: {
    rules: [
      {
        test: /\.(png|jpe?g|webp|git|svg|)$/i,
        use: [
          {
            loader: 'img-optimize-loader'
          },
        ],
      },
    ],
  },
};
