To use a custom style loader in Vite, you can add a custom plugin to Vite's build pipeline. Here's a step-by-step guide on how to do it:

  1. Create a new JavaScript file for your custom style loader plugin. For example, you can name it custom-style-loader.js.
  2. In this file, define your custom style loader function. Here's an example implementation using PostCSS loader:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
const postcss = require('postcss');

module.exports = function customStyleLoader(source, map) {
  const result = postcss()
    .use(/* your PostCSS plugins here */)
    .process(source, { from: undefined })
    .sync();
  
  return {
    code: result.css,
    map: result.map,
  };
};


  1. Register your custom style loader as a Vite plugin in your vite.config.js file:
1
2
3
4
5
6
import { defineConfig } from 'vite';
import customStyleLoader from './custom-style-loader.js';

export default defineConfig({
  plugins: [customStyleLoader()]
});


  1. You can now use your custom style loader by importing CSS files in your JavaScript files:
1
import './styles.css';


  1. Run Vite development server to see your custom style loader in action:
1
npm run dev


That's it! You have successfully set up and used a custom style loader in Vite. Feel free to customize the customStyleLoader function to suit your specific needs.
