go-playground/validator
20,028View on GitHubThis is a Go struct validation library used to maintain data integrity by enforcing constraints on fields, slices, and maps. It functions as a schema validation tool and data integrity validator, ensuring that complex nested structures adhere to predefined rules. The library utilizes struct tags to configure validation logic at runtime and supports a custom function registry for extending validation rules. It is distinguished by its ability to perform cross-field dependency evaluation, allowing the comparison of values between different fields within the same data structure to ensure logical
This library is the industry-standard tool for Go struct validation, offering comprehensive support for struct tags, custom rules, cross-field dependencies, and nested validation.

4,072View on GitHubozzo-validation is a programmable data validation library for Go that verifies structs, maps, and primitive types using a declarative, rule-based approach. It functions as an interface-based validator, allowing for the recursive checking of nested data structures and custom types without the use of struct tags. The framework distinguishes itself as a context-aware validation engine, supporting the propagation of request-scoped data to rules that depend on external state. It provides extensive extensibility through custom rule definitions and the ability to override default failure text with l
This library provides a robust, interface-based approach to validating Go structs and nested data structures, offering extensive support for custom rules and complex validation logic without relying on struct tags.

1,335View on GitHubThis project is a data validation framework for the Go programming language that enforces integrity by applying declarative constraints to struct fields. It utilizes reflection to inspect data structures at runtime, mapping field-level requirements defined in struct tags to specific validation logic. The library distinguishes itself through its ability to handle complex object graphs by recursively traversing nested structures and slices. It supports context-aware validation, allowing developers to switch between different rule sets for the same data structure based on application state or sp
This library is the standard Go framework for struct-based data validation, offering comprehensive support for nested structures, custom rules, and cross-field validation via struct tags.
