keep docs in sync with OpenAPI

I can help with that. A good “keep docs in sync with OpenAPI” setup usually means making the OpenAPI spec the source of truth and generating or validating docs from it.

Here are the common approaches:

1. Generate docs from OpenAPI

   • Use tools like:
     • Swagger UI / Redoc for interactive API docs
     • openapi-generator or swagger-codegen for client/server stubs
     • redocly for polished docs sites
   • Benefit: docs update automatically when the spec changes.

2. Validate docs against the spec in CI

   • Add a pipeline step that checks:
     • the OpenAPI file is valid
     • examples match schemas
     • referenced endpoints/fields in markdown docs still exist
   • Tools:
     • spectral
     • openapi-cli
     • redocly lint
     • custom scripts for markdown/code snippet validation

3. Embed snippets from the spec

   • Keep examples in the OpenAPI file and pull them into docs.
   • Avoid duplicating request/response examples in separate markdown files.

4. Use a docs build step

   • If you have MkDocs, Docusaurus, or Sphinx:
     • import rendered OpenAPI sections or generated HTML
     • fail builds if the spec and docs diverge

5. Make the spec mandatory in PRs

   • Require OpenAPI changes when API behavior changes.
   • Add a checklist:
     • OpenAPI updated
     • docs regenerated
     • examples verified

If you want, I can help you with any of these specifically:

• a CI pipeline example to enforce sync
• a repo structure for docs + OpenAPI
• a script to compare docs with spec
• a tool recommendation for your stack
