Feature request: @Optional decorator

[koldoon]

@optional decorator would be a great addition to collection, instead of property like at the moment

[AmauryD]

Hello, do you mean something like this ?

@Schema()
class Entity2 {
  @UUID()
  prop1: string;

  @Enum({ values: ["one", "two"] })
  prop2: "one" | "two";

  @Email()
  @Optional()
  prop3: string;

  @Number({ positive: true })
  @Optional()
  prop4: number;

  @Nested()
  prop5: Entity1;
}

@AmauryD Yepp, exactly. This is especially useful with implicit "multi" rule, where it is not very clear how to define the whole property optional (I personally apply {optional:true} to each validator decorator just in case):

export class ActionParams {
  @String({ optional: true })
  @Array({ optional: true, items: 'string' })
  code?: string | string[];
}

Better would be:

export class ActionParams {
  @Optional()
  @String()
  @Array({ items: 'string' })
  code?: string | string[];
}
