What is validator?
Validator is a Go package that provides struct and field validation using tags. It solves the problem of ensuring data integrity in Go applications by offering a declarative way to validate structs, including complex scenarios like cross-field validation and deep diving into nested collections. It is widely used as the default validator for the Gin web framework.
Go developers building web services, APIs, or any application requiring robust input validation, especially those using structs to model data.
Developers choose Validator for its extensive built-in validation tags, high performance, and flexibility in handling complex validation scenarios like nested structures and custom types, all while maintaining a simple tag-based API.
