# Hono Coding Guidelines ## Requirements - Hono ≥ 4.0, @hono/node-server, @hono/zod-validator, TypeScript ≥ 5.8 ## Essentials - **Factory functions** - Use for testability and domain organization, see [references/application-structure.md](references/application-structure.md) - **Type-safe validation** - Recover types at the `c.req.valid` boundary; schema design in **zod-guide**, see [references/validation-type-safety.md](references/validation-type-safety.md) - **Middleware configuration** - Use factories for CORS, composition with `some()`/`every()`/`except()`, see [references/middleware-patterns.md](references/middleware-patterns.md), [references/middleware-combine.md](references/middleware-combine.md) - **WebSocket helpers** - Keep object references to maintain `this` binding, see [references/websocket-support.md](references/websocket-support.md) - **Error responses** - Use RFC 9457 Problem Details with `application/problem+json`, see [references/error-handling.md](references/error-handling.md) - **Security middleware** - Apply `secureHeaders()` for security headers, see [references/security-middleware.md](references/security-middleware.md) - **Cookie handling** - Set secure options explicitly, use signed cookies, see [references/cookie-handling.md](references/cookie-handling.md) - **Platform portability** - Use `env(c)` for environment, `getRuntimeKey()` for detection, see [references/platform-runtime.md](references/platform-runtime.md) ## Example ```typescript impor
