Creates a pipeline validation action that validates the size of a map, set or blob.

const Validation = notSize<TInput, TRequirement>(requirement, message);


  • TInput extends Map<any, any> | Set<any> | Blob
  • TRequirement extends number



With notSize you can validate the size of a map, set or blob. If the input does not match the requirement, you can use message to customize the error message.



The following examples show how notSize can be used.

Blob size schema

Schema to validate a blob with less ore more then 10 MB.

const BlobSchema = blob([
  notSize(10 * 1024 * 1024, 'The blob must not be 10 MB in size.'),

Set size schema

Schema to validate a set with less ore more then 8 numbers.

const SetSchema = set(number(), [
  notSize(8, 'The set must not contain 8 numbers.'),

The following APIs can be combined with notSize.
