API-First with Hono: OpenAPI to Typed Routes Without Lock-in

Short summary

Hono enables API-first development by generating Zod schemas from OpenAPI specs using @apical-ts/craft, then applying a custom generator to create type-safe routes without framework lock-in. This hybrid approach maintains strong developer experience while preserving long-term flexibility to migrate frameworks. Full working example provided.

• •API-first with Hono avoids framework lock-in while maintaining type safety
• •Use @apical-ts/craft to generate Zod schemas and route metadata from OpenAPI
• •Custom generators transform metadata into idiomatic Hono code
