Utilizing Vue.js and Webpack for Webpage Optimization with Responsive Image Loading and Sharpness Enhancement

When utilizing responsive-loader, I was anticipating an object as the return value. However, what I am getting instead is a base64 string in the format of

data:image/jpeg;base64,bW9kdWxlLmV...
.

Unfortunately, the solutions from other posts that I have come across did not resolve my particular issue.

Vue version 3.2.31, Responsive Loader version 2.3.0, Sharp version 0.30.3

Contents of vue.config.js file

const NodePolyfillPlugin = require('node-polyfill-webpack-plugin')
const ResponsiveLoaderSharp = require('responsive-loader/sharp')

module.exports = {
    chainWebpack: config => {
        config.plugin('polyfills').use(NodePolyfillPlugin)

        config.module
            .rule('images')
            .use('url-loader')
            .loader('responsive-loader')
            .options({
                adapter: ResponsiveLoaderSharp,
                name: 'img/[name]-[width].[hash:8].[ext]',
                format: 'webp',
                quality: 60,
                sizes: [320, 640, 960, 1200],
            })
    },
}

Vue Template code snippet

<script lang="ts">
import { defineComponent } from 'vue'

export default defineComponent({
    setup(){
        const myImage = require('@/assets/my-image.jpg')

        console.log(myImage)
    }
})
</script>

Answer №1

The main issue revolved around the utilization of Webpack's latest asset modules feature.
https://webpack.js.org/guides/asset-modules/

Below showcases the initial compiled Vue3 Webpack setup:

      /* config.module.rule('images') */
      {
        test: /\.(png|jpe?g|gif|webp|avif)(\?.*)?$/,
        type: 'asset',
        generator: {
          filename: 'img/[name].[hash:8][ext]'
        }
      },

To make adjustments, type: 'asset' must be overwritten with type: 'javascript/auto' to avoid duplication of assets.

Utilizing chainWebpack (not documented before this point):

config.module
    .rule('images')
    .type('javascript/auto')
    .use('responsive')
    .loader('responsive-loader')
    .options({
        adapter: require('responsive-loader/sharp'),
        format: 'webp',
    })
