CSS Build Tools

In modern web development, CSS build tools are essential for automating the workflow. These tools help optimize code, manage modules, and speed up the development cycle.

PostCSS and script-based build

PostCSS allows processing CSS with various plugins such as autoprefixer or cssnano. It is often combined with NPM scripts to run the build process automatically.

This example demonstrates how to configure PostCSS to run from an NPM script.

Webpack and CSS integration

Webpack is one of the most widely used build tools that allows handling CSS, JS, and other resources within a single modular system. With css-loader and style-loader, CSS can be directly integrated into JavaScript code.

This configuration example demonstrates how to load CSS files with Webpack.

Tips for build tools

Some best practices for using CSS build tools.

Choose a build tool based on project needs: Parcel or Vite may be enough for smaller projects, while Webpack is recommended for larger projects.
