How to add a custom pipe to server.ts?

[VicAlar]

Hello, I created a new Pipe for The validation using Class-Validator but i'm nota seeing the way to correctly implement it inside my server.ts to be used for all the routes.

I did the override method for the default ValidationPipe.

Hello @VicAlar
Override ValidationPipe isn't encouraged because Ts.ED use @tsed/schema to map object, validate it and generate documentation.
Removing one of this point downgrade the Dev experience with Ts.ED.

Also any issue related to class-validator/Ts.ED won't be supported by us!

But the solution is the following

import {ValidationPipe} from "@tsed/platform-params";
import {JsonParameterStore} from "@tsed/schema";
import {OverrideProvider} from "@tsed/di";

@OverrideProvider(ValidationPipe)
export ClassValidatorPipe extends ValidationPipe {
  async transform(value: any, metadata: JsonParameterStore): Promise<any> {
   /// do something
  } 
}

Then in Server.ts add the following code:

import "./pipes/ClassValidatorPipe";

It should works.

See you
