Validation pipe options
Let's set some useful options in our Validation Pipe.
Our ValidationPipe is working, but we may want more strict validation. Currently we can send properties not present in the DTO. However, this may lower our overall security. Therefore, let's go back to our pipe instantiation in the CommonModule and insert an options object with the following properties:
The first option strips the object of non-present properties. The second one, combined with the first one, instead of stripping the object, throws an exception.
We can also set the transform option so that the incoming JSON will automatically be transformed from a plain object to an instance of the corresponding DTO.
