validator — Go Struct and Field Validation Library with Advanced Features

Overview

validator is a Go library that provides powerful struct and field validation capabilities, including cross-field, cross-struct, map, slice, and array diving. It stands out for its unique features such as custom field types, alias validation tags, and i18n error messages, making it a robust choice for complex validation scenarios.

Key Features

Cross Field and Cross Struct validations using tags or custom validators
Slice, Array, and Map diving for multidimensional field validation
Customizable i18n aware error messages
Supports custom field types and interface types

Use Cases

Web frameworks like Gin for validating user input
Data validation in backend services
Form validation in Go applications

Advantages

Comprehensive validation capabilities for complex data structures
Customizable error messages for better user experience
Supports a wide range of data types, including custom types

Limitations / Considerations

The library may have a steeper learning curve due to its advanced features
Performance considerations for very large datasets

govalidator: A simple and easy-to-use validation library, but with fewer advanced features compared to validator.
x-validation: A library that focuses on translations and custom errors, but lacks some of the advanced validation capabilities of validator.
