  • Show HN: Monocle – bidirectional code generation library
    10 projects | news.ycombinator.com | 12 Apr 2022
    I use a mixed approach for OpenAPI, but not bidirectional.

    I have OpenAPI pieces generated from my Go source code (comment, types, function signatures) as JSON.

    I also have a manually-edited master YAML document that refers to generated bits via $ref links.

    I then use openapi-preprocessor [1] (disclaimer: I wrote it) to produce a final openapi.json file which is committed in the repo.

    When I want to extend the API in a spec-first process, I can add the new routes manually in the YAML file. When I do the implementation I replace the manual bits by the generated one when they are ready. When committing I can check the diff of openapi.json to verify I'm not losing in the process.

  • JSON Schema bundling finally formalised
    9 projects | news.ycombinator.com | 10 Sep 2021
    Bundling for OpenAPI specification has long been a need for authors to allow to reduce duplication, and to allow to split a big specification in multiples files, but publish a single one.

    A few years ago I've written a tool to fit that niche: https://github.com/dolmen-go/openapi-preprocessor

    https://github.com/dolmen-go/openapi-preprocessor

    I have now to tweak it (well, it will be a major rewrite) to handle $ref relative to $id instead of the file location.

  • gRPC gateway vs oapi-codegen etc.
    1 project | /r/grpc | 14 Apr 2022
    The tool for generating OpenAPI docs from a proto definition is gnostic (https://github.com/google/gnostic). But see the comments in this issue about conversion the other way (from OpenAPI to proto): https://github.com/google/gnostic/issues/162
