Next.js currently lacks comprehensive built-in type safety for routing, which can lead to issues like broken links and incorrectly formatted query strings. Although it has an experimental feature for statically typed links, this feature has many limitations, including a lack of type validation for route or query string parameters and no runtime validation. To create a robust type-safe routing system, the text suggests using the Zod library for both type and runtime validation of routes and query parameters, offering a way to decouple route names from URLs and provide type-safe useParams() and useSearchParams() functions. The proposed solution involves defining routes using a RouteBuilder interface, which includes static and runtime validations, enabling developers to easily restructure URLs without updating links throughout the application and ensuring robust error handling and type safety.
