Hono Project Structure
The ultrafast web framework for the edge. Hono is designed to be extremely lightweight and runtime-agnostic, featuring a clean TypeScript architecture that supports Cloudflare Workers, Deno, Bun, and Node.js with a single codebase.

Architecture Notes
Hono is built with a focus on 'Zero Dependencies' and 'Edge First'. Its architecture is designed around a core Request/Response cycle that remains consistent across all supported runtimes. The adapter/ directory is the most interesting part of the codebase, as it shows how Hono abstracts away runtime-specific APIs (like Deno's networking or Cloudflare's bindings) to provide a unified developer experience. It also features multiple router implementations that are chosen at runtime based on the complexity of the routes, ensuring the best possible performance.
Key Directories
- src/adapter/-The abstraction layer that allows Hono to run on any JavaScript runtime
- src/router/-Houses the high-performance routing engines that are the heart of Hono's speed
- src/middleware/-Contains standard web middlewares like CORS, Logger, and Basic Auth implemented for the edge
Why This Structure?
Hono is the gold standard for modern TypeScript library design. It shows how to build a multi-runtime framework that is both extremely powerful and remarkably simple to understand. It's a required study for anyone interested in the future of web development and edge computing.
