I got tired of lack of type safety in localStorage and alike apis, wanted to make something simple, easy to use while maintaining performance. It has zero dependencies, near native get\set performance, basic reactivity, validation, type safety, serialisation and is flexible enough to be used with various storage solutions. My goal is to gain some traction on this library, gather feedback
