Express Zod Safe is a TypeScript-first middleware for Express.js applications, offering robust and typesafe validation of incoming HTTP request bodies, URL parameters, and query strings. It leverages Zod schemas to define validation rules, ensuring data integrity and preventing invalid or malicious data from reaching application logic. The current stable version is 3.2.1, which targets Zod v4.0.0 and above. While a specific release cadence isn't published, it appears to follow Zod's major version updates. Key differentiators include its strict type safety, seamless integration with the Express middleware stack, comprehensive coverage of request parts (body, params, query), and developer-friendly error handling, aiming to be a more robust alternative to similar packages like `zod-express-middleware`.
