What is Skypack?
Skypack is a content delivery network (CDN) that provides pre-optimized JavaScript packages for direct use in browsers, eliminating the need for complex bundlers. It simplifies web development workflows by offering a global CDN that handles minification, browser polyfilling, compression (gzip/brotli), HTTP/3, and caching. This allows developers to instantly speed up websites by leveraging modern web optimizations that were previously only available to large tech companies.

It aims to make the web more open and accessible by providing free, optimized hosting for open-source JavaScript code, supporting web standards, and simplifying the integration of external packages into web projects.
