Cannot use typia with generic functions (Angular, TypeScript)

[deyan-peychev]

I have an Angular application and I'm creating a PayloadValidationService which has a generic function that uses typia's validateEqual to validate objects:

import { Injectable } from "@angular/core";
import typia from "typia";

@Injectable({
  providedIn: 'root'
})
export class PayloadValidationService {

  validatePayload<T>(payload: object): void {
    console.log(typia.validateEquals<T>(payload)); // There will be additional functionality if the result is an error
  }

}

I am using the function as follows:

interface MyPayload {
    someValue: string;
}

@Injectable({
    providedIn: 'root'
})
export class MyService {

    constructor(private payloadValidationService: PayloadValidationService) {}
    
    myApiRequest(data: any) {
        this.payloadValidationService.validatePayload<MyPayload>(data);

        // ... 
    }
}

This throws the following error in the console:

ERROR Error: Error on typia.validateEquals(): no transform has been configured. Read and follow https://typia.io/docs/setup please.

If I use the validateEquals directly with my interface and not use generics (e.g. typia.validateEquals<MyPayload>(data)), everything works normally without any errors.

Is there any way to make it work with generics?

Angular version: 17
Typia version: "^5.4.0"
I have run npm install typia and npx typia setup

Too much duplicated question, and not possible to do it.

To accomplish the feature, I've to remake Typia and TypeScript compiler entirely.

Utilize typia.createAssert<T>() like functions intead please.
