## Notes

Mastro is a web framework and site generator for JavaScript and TypeScript. It builds static multi-page websites, and it can also run as a server that renders pages on demand. It runs on Node.js, Deno, Bun or Cloudflare Workers, and a project is created with pnpm create @mastrojs/mastro. The code is published on JSR as @mastrojs/mastro, and the license is MIT.

Static output can be served from any CDN, and a server can run on Deno, Node.js or Bun. Mastro can also run code inside a Service Worker in the visitor's browser, as an option on top of the default.

## Worth knowing

The older npm package named mastro is flagged deprecated on npm; the install commands above use the current package.
