Request Validation

The @Validation decorator can be used to validate the request body or query parameters:

src/controllers/user.controller.ts
import {
  Application,
  ControllerBase,
  KultController,
  Post,
  Validate,
} from '@kult/core';

@KultController('/users')
class UserController extends ControllerBase {
  constructor(app: Application) {
    super(app);
  }

  @Post('/create')
  @Validate({
    name: 'required|type:string|max:10',
    age: 'required|type:number',
    profile: {
      avatar: 'type:string',
    },
  })
  create() {
    return 'User created.';
  }
}

export default UserController;
