Why doesn’t Node.js have something like Django’s Class-Based Views (CBVs)?

I love Django key features like its class-based views or ORM, and I usually miss them when working with Node.js. So yesterday night, in the middle of my usual insomnia, I wondered if anyone had already built something like that for Node.js.

I did a quick search, and what I found were just a few experiments from ~8–9 years ago. Nothing robust, modern, or maintained.

Django Class-Based Views (CBVs) provide a clear structure, lots of built-in functionality, and still enough flexibility to adapt them to different use cases. So I decided to sketch out a design for Fastify (and Node.js in general) that feels natural to use, contract-first, and TypeScript-friendly. This post is a walk-through of that exploration during the rest of the Sunday.

When designing web services, it’s normal to include an option to delete an user’s account. Since this is an important action (the user and its data will dissapear from the platform), usually this is done by asking him to confirm the operation, with several endpoints one for each operation step. Navigating between different pages is so 2010-style, and there’s no direct mapping at this point between REST APIs and CRUD operations, that I’ve been thinking in a REST compatible alternative: use a token.
