Show HN: Define a production-ready backend CRUD FastAPI using a JSON schema

https://rationalbloks.com/
1•victorveloso•3w ago

victorveloso•3w ago
I am a mechanical engineer with a deep interest in the reliability of engineering systems and the power of logical reasoning. It's been a while since I've been learning coding with the objective of creating my own 'systems engineering application'. It's almost an obsession for me working on this project. So, as the years went by, I've tested several frameworks for web development.

The thing is, I realized I was spending way too much time writing CRUD code instead of spending that time on the business logic itself. I came to the realization that we need to systematize the things that can be systematized. I'm a big believer in splitting CRUD and business logic apart; while the CRUD infrastructure follows repetitive coding patterns, the business logic varies from app to app.

Now, I know that Backend-as-a-Service isn't something new. However, I wanted a tool that was extremely easy to use. I figured out that a JSON file would be a perfect way to describe a database SQL structure in a simple manner. I really didn't want any fancy user interfaces for dealing with the data structure. By using a JSON file, the infrastructure becomes Git-trackable. This approach prioritizes reliability by ensuring every state of the data structure remains easily traceable over time.

Since I love FastAPI and PostgreSQL, I present to you the tool I've built: RationalBloks (https://rationalbloks.com).

It is a humble attempt to automate the generation of a production-ready backend ecosystem. By defining a single JSON schema, RationalBloks handles the heavy lifting: generating the FastAPI application, configuring the PostgreSQL database, implementing JWT authentication, and creating all the Kubernetes production-ready infrastructure.

I truly hope the community finds some value in this. I am very much open to technical debates, suggestions, and any insightful discussions that can help make this tool better for everyone. Please feel free to reach out to me: victorveloso@rationalbloks.com
