Project mention: Literate programming: Knuth is doing it wrong (2014) | news.ycombinator.com | 2025-01-13
The package Jeremy Howard uses for Claudette, nbdev, actually does address the notebook pain points of version control, testing, integration, and deployment: https://nbdev.fast.ai/ (Debugging is already a strong point of developing within a notebook.) But it's admittedly used mostly for solo projects or small teams and may not be ready for large orgs.

-
Third-Party Packages: OpenAPI support via packages like drf-yasg (OpenAPI 2.x / Swagger) and drf-spectacular (OpenAPI 3.x).
-
Solutions to this problem generate API documentation automatically. Libraries such as drf-spectacular use code structure and semantics in back-end frameworks to infer API contracts. API frameworks such as FastAPI and Huma generate OpenAPI specifications as a built-in feature. Tools like mitmproxy2swagger generate documentation from HAR files. Finally, companies such as Akita Software/Postman use network traffic metadata.

This year, I've had to get rapidly up-to-speed with GraphQL. I thought I'd be starting from nothing, but I'd forgotten that TinaCMS (the headless content management system that I use with this site) uses it. One of the first problems I had to solve was how to generate static documentation. My limited research led me to two possible solutions: SpectaQL, developed from the earlier DociQL, and Magidoc. The latter has built-in search, so that made my choice for me. I use Hugo as my static site generator, so the first thing I had to do was start the local version of TinaCMS from my site's Git repository:
