Preface

Why not develop Cloudflare Workers services using Ruby?

This web book is a hands-on guide to Uzumibi, a framework for developing edge services with Ruby. You'll learn its core features step by step as you build real projects.

Uzumibi is powered by mruby/edge, an implementation of mruby. The resulting artifacts are tiny — for typical use cases, they can be under 500 KiB even after compression.

We hope this book opens up a new frontier for you at the intersection of Ruby and the edge.
