What This Skill Covers
- Hono provides only a very thin Validator. However, it can be powerful when combined with a third-party Validator. In addition, the RPC feature allows you to...
- Main sections:
Manual validator,Multiple validators,With Zod,Zod Validator Middleware,Standard Schema Validator Middleware.
Workflow
- Open the most relevant file under
docs/for the exact documented workflow and wording. - Open
schemas/files for exact structured contracts. - Open
examples/files for concrete requests, commands, snippets, and manifests. - Do not add behavior or configuration that is not present in the attached source files.
