GoLidator

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.

Installation

To install GoLidator, use the go get command:

go get github.com/renxzen/golidator

Usage

Import the golidator package 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.Validate function to check for validation errors:

data := YourStruct{
    Field1: "test@example.com",
    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
}

Supported Validators

notblank: Ensures that a string is not empty.
email: Validates that a string is a valid email address.
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.
isarray: Ensures that a field is a non-nil array and validates its elements recursively.

Todo

custom validators
validate array without isarray
optimize reflection in loops
simplify conditional checks
reduce redundancy with type errors
