Like Hono, you can easily create a backend web framework using Web Standards APIs such as Request and Response. These run on Cloudflare Workers, Deno, Bun, etc. In this talk, I will introduce how to make it, such as implementing routing using URLPatterns, Hono/Express-like syntax, middleware mechanisms, and server-side rendering with React. This is reinventing the wheel, but making your framework is fun!
