css-modules-require-hook

What is css-modules-require-hook?

The css-modules-require-hook package is a tool that allows you to use CSS Modules in Node.js by transforming CSS files into JavaScript objects. This is particularly useful for server-side rendering (SSR) and testing environments where you need to handle CSS files in a Node.js context.

What are css-modules-require-hook's main functionalities?

Basic Setup

This feature allows you to set up the css-modules-require-hook with a custom naming pattern for the generated CSS class names. The code sample demonstrates how to configure the hook and require a CSS file, which will be transformed into a JavaScript object.

const hook = require('css-modules-require-hook');

hook({
  generateScopedName: '[name]__[local]___[hash:base64:5]'
});

const styles = require('./styles.css');
console.log(styles);

Custom Preprocessor

This feature allows you to use a custom preprocessor like Sass. The code sample shows how to configure the hook to preprocess SCSS files using node-sass before transforming them into JavaScript objects.

const hook = require('css-modules-require-hook');
const sass = require('node-sass');

hook({
  extensions: ['.scss'],
  preprocessCss: (data, filename) => {
    return sass.renderSync({
      data,
      file: filename
    }).css;
  }
});

const styles = require('./styles.scss');
console.log(styles);

Custom CamelCase

This feature enables the conversion of CSS class names to camelCase in the resulting JavaScript object. The code sample demonstrates how to configure the hook to use camelCase and access the class names in camelCase format.

const hook = require('css-modules-require-hook');

hook({
  camelCase: true
});

const styles = require('./styles.css');
console.log(styles);
console.log(styles.someClassName); // Access class names in camelCase

postcss-modules

postcss-modules is a PostCSS plugin that enables the use of CSS Modules. It provides more flexibility and can be integrated into a broader PostCSS setup, making it suitable for build processes that already use PostCSS. Unlike css-modules-require-hook, it is not limited to Node.js environments.

css-modules-loader-core

css-modules-loader-core is a low-level library for loading and processing CSS Modules. It provides the core functionality needed to implement CSS Modules in various environments. While css-modules-require-hook is a higher-level tool for Node.js, css-modules-loader-core offers more granular control and can be used to build custom solutions.
