What is Rucksack?
Rucksack is a lightweight Node.js-based CSS bundling tool designed to improve website performance. It analyzes CSS files and finds @import rules, then bundles all the imported files into a single CSS file. This helps reduce the number of HTTP requests made by the browser.
Key features of Rucksack:
- Bundles CSS files by inlining @imported files
- Minifies CSS files to reduce file size
- Adds CSS3 vendor prefixes automatically using Autoprefixer
- Easy to configure and integrate into build processes
