Strict validation in TypeScript schemas is achieved by applying strictObject, which rejects unknown fields and ensures data contracts precisely match expected payloads. This prevents extraneous data from passing silently and clarifies data structures across modules.

The best way to add metadata to Zod schemas is by applying .meta() on every field. This attaches rich metadata-driven documentation and validation hints directly to the schema definition, making the data contracts self-documenting and easier to maintain.

Yes, you can safely compose and extend Zod schemas across modules using the safeExtend pattern. This enables layered schema composition, allowing scalable schema design by building complex types from base schemas without breaking existing validation logic.

Yes, this schema validation approach works for validating API payloads and IPFS metadata structures. By combining strictObject with per-field .meta() descriptors, you create strongly typed schemas that validate complex nested data reliably.

You should use strictObject instead of standard object schemas to reject unknown fields during validation. Standard objects allow extra properties, but strictObject enforces exact data contracts, reducing runtime errors from unexpected payload properties.
