HonoJS

A lightweight, ultrafast web framework built on Web Standards for building APIs and serverless applications. Uses the Web Standard API with zero dependencies and runs on any JavaScript runtime: Cloudflare Workers, Fastly Compute, Deno, Bun, Vercel, Netlify, AWS Lambda, Lambda@Edge, and Node.js.

Hono differentiates by offering true multi-runtime portability: the same application code deploys to edge, serverless, or traditional Node without changes. Its RegExp-based router avoids linear routing loops for high throughput. The framework ships with a tiny preset under 12kB, making it suitable for constrained environments like edge runtimes.

Key capabilities:

• Ultrafast routing with RegExpRouter and multiple router implementations
• Built-in middleware for JWT, CORS, compression, caching, logging, and secure headers
• First-class TypeScript support with end-to-end type inference
• JSX rendering and RPC-style client generation
• WebAssembly WASI support for running beyond JavaScript runtimes

Developers use Hono for edge APIs, serverless backends, and full-stack apps where a single codebase must target Cloudflare Workers, Vercel, or AWS Lambda. Its clean handler API and middleware composition suit microservices and BFF layers. Integrations with Next.js, Supabase Functions, and most major serverless platforms allow quick deployment without vendor lock-in.
