GoLidator is a lightweight and flexible validation library for Go (Golang). It provides a simple and extensible way to validate data structures based on struct tags.
To install GoLidator, use the go get command:
go get github.com/renxzen/golidator- Import the
golidatorpackage in your code:
import "github.com/renxzen/golidator"- Create a struct with validation tags:
type YourStruct struct {
Field1 string `validate:"notblank,email"`
Field2 int `validate:"min=10,max=100"`
// Add more fields and validation tags as needed
}- Use the
golidator.Validatefunction to check for validation errors:
data := YourStruct{
Field1: "[email protected]",
Field2: 5,
// Set values for other fields
}
validationErrors, err := golidator.Validate(data)
if err != nil {
// Handle error
}
if len(validationErrors) > 0 {
// Handle validation errors
for _, ve := range validationErrors {
fmt.Printf("Field: %s, Errors: %v\n", ve.Field, ve.Errors)
}
} else {
// Data is valid, proceed with your logic
}notblank: Ensures that a string is not empty.email: Validates that a string is a valid email address.numeric: Validates that a string contains only numbers.url: Validates that a string is a valid URL.required: Ensures that a field is not missing from the body.notempty: Ensures that an array is not empty.min: Validates that a string or numeric value is greater than or equal to a specified limit.max: Validates that a string or numeric value is less than or equal to a specified limit.len: Validates that a string or a slice value has the same amount of characters or elements.isarray: Ensures that a field is a non-nil array and validates its elements recursively.
- custom validators
- validate array without
isarray - optimize reflection in loops
- simplify conditional checks
- reduce redundancy with type errors
