Asked By CuriousCoder42 On

I'm working on a Python backend that uses Pydantic for data validation, and I've been wondering how to ensure that my data structures remain harmonized between Pydantic and PostgreSQL. Are there any tools or approaches that can help me sync data structures across different languages and platforms without too much manual effort?

One way to think about this is that when you send data over the network, it's usually converted to strings. Libraries can help validate your JSON payloads to ensure they match the expected structure, but you'll need to decide how closely you want to maintain mirrored structures between your backend and frontend. GraphQL can assist with defining request schemas, but I'm curious—does that address your issue?

Consider using OpenAPI! It's pretty handy for keeping your backend and frontend types aligned. There are various client code generation tools that can help with this, but I must say, most require a bit of tweaking to get them just right.

If you're looking for something simpler than GraphQL, it might be worth exploring other options to reduce the overhead of integrating and maintaining the data structure. However, I'm not sure what the alternatives are! Maybe someone else has tips on that?
