superstruct vs yup

superstruct is geared towards developers looking for a simple and composable way to validate data structures, supporting both JavaScript and TypeScript effectively. It is lightweight and well-suited for smaller projects or when minimalistic validation is needed. In contrast, yup provides a more extensive feature set for object schema validation and is favored for its dead-simple API, appealing to developers working with complex data structures.

When deciding between superstruct and yup, consider your project's scope and your team's familiarity with schema validation. If your application requires extensive validation logic or you anticipate the need to handle complex types, yup may be the preferable choice due to its broader functionality and larger community support. Conversely, if you are looking for a straightforward and quick solution, superstruct's simplicity and smaller size make it an attractive option.

Both libraries have open issues to address, with yup having a higher number, which could indicate ongoing active development but may also pose challenges if you encounter issues. In terms of size, superstruct has the advantage of being smaller both in unpacked and gzipped form, which may be beneficial for performance-focused applications. Consider these aspects when migrating or integrating validation into your existing projects.
