💻 Code Usage Examples

Example 1: Struct Validation

import "github.com/asaskevich/govalidator"

type Server struct {
    Name    string `valid:"required,alphanum"`
    IP      string `valid:"required,ip"`
    Port    int    `valid:"required,range(1|65535)"`
    Email   string `valid:"email"`
}

server := &Server{
    Name:  "prod-server-01",
    IP:    "192.168.1.1",
    Port:  8080,
    Email: "admin@example.com",
}

result, err := govalidator.ValidateStruct(server)
if err != nil {
    log.Fatal(err)
}

Example 2: URL/IP Validation (Kubernetes/Helm Pattern)

import "github.com/asaskevich/govalidator"

// Validate Chart.yaml URLs in Helm
func validateChartURL(url string) error {
    if !govalidator.IsURL(url) {
        return fmt.Errorf("invalid URL: %s", url)
    }
    return nil
}

// Validate IP address
func validateIPAddress(ip string) bool {
    if govalidator.IsIPv4(ip) {
        return true
    }
    if govalidator.IsIPv6(ip) {
        return true
    }
    return false
}

Example 3: Email Validation

import "github.com/asaskevich/govalidator"

type User struct {
    Email string `valid:"email,required"`
    Name  string `valid:"required,length(3|50)"`
    Age   int    `valid:"required,range(18|120)"`
}

user := &User{
    Email: "user@company.com",
    Name:  "John Doe",
    Age:   30,
}

_, err := govalidator.ValidateStruct(user)
if err != nil {
    // Handle validation errors
    log.Printf("Validation failed: %v", err)
}

Example 4: Custom Validators (Advanced Usage)

import "github.com/asaskevich/govalidator"

// Register custom validator
func init() {
    govalidator.TagMap["kubernetes_name"] = govalidator.Validator(func(str string) bool {
        // Kubernetes resource name validation
        return regexp.MustCompile(`^[a-z0-9]([-a-z0-9]*[a-z0-9])?$`).MatchString(str)
    })
}

type KubernetesResource struct {
    Name      string `valid:"kubernetes_name,required"`
    Namespace string `valid:"kubernetes_name,required"`
}

Example 5: PKI Validation (HashiCorp Vault Pattern)

import "github.com/asaskevich/govalidator"

type CertificateRequest struct {
    CommonName       string `valid:"required"`
    Organization     string `valid:"required"`
    OrganizationUnit string `valid:"optional"`
    Country          string `valid:"iso3166_1_alpha2"`
    EmailAddress     string `valid:"email"`
}

certReq := &CertificateRequest{
    CommonName:   "example.com",
    Organization: "Example Inc",
    Country:      "US",
    EmailAddress: "admin@example.com",
}

_, err := govalidator.ValidateStruct(certReq)
