Seonglae ChoHyper-Typing refers to a phenomenon where pursuing perfect type safety in TypeScript leads to excessively complex type definitions.
TanStack Form library exemplifies this with its
FieldMeta type that uses 17 generic parameters, creating complexity that makes it difficult for users to understand the type definitions.Hyper-Typing
In this article, I talk about an inherent trade-off in TypeScript's type system: stricter types are safer, but often more complex. I describe a phenomenon I call "hyper-typing", where libraries - in pursuit of perfect type safety - end up with overly complex types that are hard-to-understand, produce cryptic errors, and paradoxically even lead to unsafe workarounds. I argue that simpler types, or even type generation, often lead to a more practical and enjoyable developer experience despite being less "perfect".
