Zod - a library based on Typescript, used to declare and validate schemas consisting of various types of data, from text to files.

Zod allows you to easily validate data from, for example: the registration form, where we can determine among others the text length or the maximum image size. You can also generate types for the Typescript language or combine different schemas into one.

The main advantages are:

• Zero dependencies
• Small size (8 KB minified + zipped)
• Works on Node.js and all modern browsers
• A large number of extensions

ZOD is often used in conjunction with React Hook Form and tRPC
