validator

Overview ¶

Package validator provides functions for validating data using the Go Playground Validator. It allows you to validate structs and individual fields, providing error messages in case of validation failures.

The package relies on the go-playground/validator/v10 library for validation and go-playground/universal-translator for translating error messages to human readable text.

Example Usage:

package main

import (
    "fmt"
    "github.com/romankravchuk/nix/validator"
)

type User struct {
    Username string `validate:"required,min=4,max=32"`
    Email    string `validate:"required,email"`
    Age      int    `validate:"gte=18"`
}

func main() {
    user := User{
        Username: "john_doe",
        Email:    "john.doe@example.com",
        Age:      25,
    }
	v := validator.New()

    if isValid := v.Validate(user); !isValid {
        fmt.Println("Validation failed:", v.Errors())
    } else {
        fmt.Println("Validation successful!")
    }
}
