zod

Enforce type-safe data contracts by defining Zod schemas to validate API inputs at runtime. Use schema.parse or schema.safeParse to guarantee consistent data shapes and prevent invalid data from flowing through services.

Validate environment variables by applying Zod schemas to parse configuration boundaries. This ensures runtime validation and static type inference, preventing invalid configurations from compromising your application.

Handle runtime validation errors by using schema.safeParse, which returns detailed error objects instead of throwing. Combine this with schema refinements to enforce custom constraints and provide robust error handling for invalid data shapes.

Transform and parse data simultaneously by defining Zod schemas with built-in transformations. This enforces strict data shape enforcement across microservices, ensuring runtime validation and static type inference for consistent data contracts.

Zod supports static type inference for database inputs by strongly typing schemas used in parsing. This guarantees runtime validation and prevents invalid data from entering database boundaries across your TypeScript services.

Use safeParse instead of parse for input validation when you expect invalid data and need to handle errors gracefully. SafeParse returns a structured result object, whereas parse throws an exception immediately upon encountering invalid data shapes.
