[Discussion] who is using `typia` in production?

[samchon]

If you're using typia in production level, can you introduce me?

It would better if you are pasting production homepage URL with logo image.

I'm planning on it!

Unfortunately it's a private enterprise app so I won't be able to share, but I'm currently on the path to migrate our existing flask backend to NestJS.

I looked at writing out class-transformers, but it's both complex for juniors to understand and our frontend schemas are already very complex. Since our frontend schemas are already defined, typia/nestia are just drop in solutions that will provide validation without any added effort. And since it all lives on the edge of the controllers, it's also a very low risk solution for us.

Hey samchon,
i'm happy to announce having switched the validators for restfuncs from typescript-rtti to Typia !
I solved it, using a 2 stage transform (which is still a bit hacky) which you can see here.

Especially i liked that Typia has a prune validator which i made the default for the lib user, so they can do cool stuff with it
Would be cool, if you list me under "Utilization cases" !

I used typia in production for a couple of products.
It is really works well.
We have so many type definitions for API, but we didn't have solutions to convert them to actual runtime code.
Typia solved it!

Here at SHI we use Typia on the SHIELD product.

We migrated to Typia back in September of 2024.

Typia is used as the corner stone of injection attack prevention in our app by requiring all functions and all methods to have all arguments go through assertGuardEquals().
We follow a assume breach model internally in our app that dictates that all functions should not trust each other and Typia is critical to that defense (in execution) in cross function compromise prevention.

We have super strict security requirements as PAW and Privileged architecture has to meet or exceed missile launch level of strict security and used to use ts-auto-guard and migrated to Typia.
