Thanks, @arielweinberger wave
Would be great to wrap the data parameter with parentheses in the map method to follow the prettier.

Thanks, @arielweinberger !

classToPlain() will be renamed to instanceToPlain() in class-validator.

I already checked operation of it. in your udemy courceblush.

import {
  NestInterceptor,
  ExecutionContext,
  Injectable,
  CallHandler,
} from '@nestjs/common';
import { instanceToPlain } from 'class-transformer';
import { map } from 'rxjs/operators';

@Injectable()
export class TransformInterceptor implements NestInterceptor {
  intercept(context: ExecutionContext, next: CallHandler<any>) {
    return next.handle().pipe(map((data) => instanceToPlain(data)));
  }
}
