ULID Validator Utility

A utility module for validating and filtering ULID strings in data processing pipelines.

Capabilities

Validates individual ULID strings

• When given a valid ULID string "01HNZX8JGFACFA36RBXDHEQN6E", the validator returns true @test
• When given an empty string, the validator returns false @test
• When given a string with incorrect length "01HNZX8JGFACFA36RBXD", the validator returns false @test
• When given a string with invalid characters "01HNZX8JGFACFA36RBXDHEQN6U", the validator returns false @test

Filters arrays of ULID strings

• When given an array containing both valid and invalid ULID strings, the filter returns only the valid ones @test
• When given an array with all invalid strings, the filter returns an empty array @test
• When given an empty array, the filter returns an empty array @test

Counts valid ULIDs in collections

• When given an array of strings, the counter returns the number of valid ULIDs @test
