Unlike other validation libraries, echt provides complete end-to-end type safety and built-in response validation while leveraging the full power of Zod's schema validation.
The useResponse schema provides granular control over response validation based on status codes. When using useResponse, you must use the .use() wrapper instead of passing the middleware directly:
The .use() wrapper is required with useResponse because it sets up the proper type inference and validation for different status codes. Without it, the middleware won't be able to properly validate responses against their corresponding status code schemas.
When using response validation, make sure to define schemas for all possible response status codes. The middleware will throw an error if you try to send a response with an undefined status code.
TypeScript Errors with Response Validation If you're seeing TypeScript errors with response validation, ensure you're using the .use() wrapper with useResponse schemas.
