This co-hosted podcast episode discusses Standard Schema, a new initiative aiming to standardize data validation across different JavaScript libraries. The hosts explain that Standard Schema isn't a new library but a specification defining how data validation should be performed and the structure of its results, promoting interoperability between various validation libraries (like Zod, ValleyBot, and Archetype) and data-handling frameworks (like TanStack Router and ExpressJS). By adopting this standard, developers avoid the need for custom adapters between different validation libraries, simplifying development and improving efficiency. The standard is implemented by adding a `~standard` annotation to schemas, ensuring consistent validation and error reporting. This standardization benefits both library authors and developers by reducing development overhead and improving code maintainability.
