Ask HN: Is there codegen framework for business logic?

I have been working on a big project for quite some time now and I am finding myself rewriting and optimizing/duplicating the code quite often and not finishing the damn thing as a whole(this is not just the programmer's strive for perfection but the mostly sheer size of the project). And I am getting really tired of writing the same stuff over and over again. I work with Go which does not have generics but I would not say that is the issue here(I actually do not miss generics, maybe once or twice a year tbh).

In essence, over the years, I grew tired of writing so much code. It's not that I do no like writing code, it's just that I clearly see how much code I need to write in order to implement the business logic. And I'm just tired of it.

So I want to create a code generator that would take my business logic and generate the full implementation out of it so I can truly focus only on that and not the code itself. I have wrote code generators before, usually for event-sourcing stuff and repositories(db), so this is nothing new. But I am after more abstraction, less time spent writing code, more time spend developing the application as a whole. Imagine something like terraform but not for infrastructure but for the code.

So before I attempt to write something on this scale I was wondering if maybe there already is something out there?

I feel the same problem! I've been writing web apps in various technologies (from backbone to react, php to Node) and always felt I had to reimplement the same common features (while using a lot of code + tests, ...).

Thinking similarly as you (terraform for code), together with my brother I started working on https://wasp-lang.dev/ - it is a DSL for building full-stack web apps. We are still very early but have some initial functionality.

Would love to hear if that resonates with what you had in mind.

We also did a quite extensive research of other solutions so happy to share what we discovered here as well.

E.g. From the purely code-generators:

https://divjoy.com/ - generates react code

https://bullettrain.co/ - Ruby on Rails starter

This looks great, even though it is new it looks polished. I am not a web developer but would like to be able to create web interfaces for APIs and other small projects I've built. This seems like it would be a great tool for things like that. Keep up the good work!

Workflow engines might be worth considering. Options from the Microsoft world include PowerApps, BizTalk and (historically) Windows Workflow Foundation.
