Feature Request: Add GoFr adapter support

Proposal: Support GoFr in Huma adapters

Hi Huma maintainers,

I would like to ask if there are plans to support GoFr (https://gofr.dev/) as an official adapter.

Currently, Huma provides adapters for several Go web frameworks. Adding GoFr support would allow developers using GoFr to leverage Huma's OpenAPI generation and validation features with a native integration.

Would this be something the project would consider?

Thanks!

Hey @robotism! Thanks for opening this request :)

I haven't personally stumbled across GoFr before, but we'd certainly welcome a PR to add support for it as an adapter if you were interested in doing so :)

Thanks, I'd be interested in contributing this. I traced the current integration surfaces before starting:

• huma.Adapter requires both Handle and ServeHTTP; the latter is used by humatest and autopatch.
• GoFr exposes route registration and UseMiddleware, but App.httpServer.router is private and gofr.Context does not expose the raw response writer. Middleware could capture the raw request/writer for registered handlers, but it still cannot implement Huma's ServeHTTP without a second router whose behavior could diverge from production.
• Huma currently targets Go 1.25. GoFr v1.56+ requires Go 1.26, so v1.55.0 is the newest compatible version Huma could pin while allowing applications to select newer GoFr releases.

Would you prefer that GoFr first expose the app's HTTP handler/router, or would a Huma adapter backed by a separate internal router for ServeHTTP be acceptable? I lean toward a public GoFr handler so production routing, tests, and autopatch all exercise the same path.

GoFr registers framework handlers but keeps the underlying HTTP router and response writer private, so a direct huma.Adapter cannot preserve Huma's raw status, headers, body, and ServeHTTP contract. The adapter bridges the raw exchange through GoFr middleware, seals Huma's response before GoFr can add its envelope, and uses a mirrored standard-library mux for ServeHTTP-based testing and autopatch.

PR incoming.

The GoFr adapter is now available in #1104. It includes exact Huma response preservation, native GoFr context access, ServeHTTP support, cross-adapter coverage, and Go 1.25 verification.

PR submitted.
