Stop Using Repetitive Validation Logic – Embrace Zod

Manual validation of request data can become messy and error-prone as a project grows, with repeated checks for missing fields and data types on every route. This can lead to duplicated code and potential errors. Zod is a TypeScript-first schema validation library that helps define what data should look like and automatically validates it. It eliminates the need for manual checks, such as if statements for missing fields or data types. With Zod, developers can define a schema for their data and reuse it across the application, including routes, services, unit tests, and even the frontend. This approach promotes cleaner, more reliable, and fully typed code. Zod works seamlessly with TypeScript, providing type-safety and runtime validation without requiring extra setup. By using Zod, developers can write better backend logic faster and avoid duplicated validation logic across their application. The library is simple to use and helps to keep validation work organized and efficient. Overall, Zod offers a more modern and efficient way to handle data validation, making it a valuable tool for backend and fullstack developers.
