Zogo - Custom Validation Library for Go

Zogo is a custom validation library for Go that allows you to define and apply various validation rules to your data. It is inspired by Zod’s zogo.

Features

Define custom validation rules for different types of data.
Easily validate fields using predefined or custom validation functions.
Intuitive and flexible way to validate complex data structures.

Installation

To use Zogo in your Go project, you can install it using the go get command:

go get github.com/frantchessico/zogo

Usage

Here’s an example of how you can use Zogo to define and validate data:


package main

import (
    "fmt"
    "github.com/frantchessico/zogo"
)

func main() {
    validator := zogo.NewRuleValidator()

    validator.AddRule("age", zogo.MinValueValidator(18))
    validator.AddRule("name", zogo.StringNotEmptyValidator)
    validator.AddRule("email", zogo.EmailSchema)
    validator.AddRule("password", zogo.MinValueValidator(4))

    data := map[string]interface{}{
        "age":     25,
        "name":    "John Doe",
        "email":   "john@example.com",
        "password": "secretpw",
    }

    err := validator.Validate(data)
    if err != nil {
        fmt.Println("Validation failed:", err)
    } else {
        fmt.Println("Validation successful!")
    }
}

Available Validation Rules

Zogo provides the following validation rules that you can use to validate your data fields:

zogo.MinValueValidator(minValue int): Validates that a numeric value is greater than or equal to the specified minimum value.
zogo.MinLengthValidator(minLength int): Validates that a string value has a minimum length.
zogo.StringNotEmptyValidator(value interface{}): Validates that a string value is not empty.
zogo.MaxLengthValidator(maxLength int): Validates that a string value has a maximum length.
zogo.MaxValueValidator(maxValue float64): Validates that a numeric value is less than or equal to the specified maximum value.
zogo.EmailSchema(value interface{}): Validates that a string value is a valid email address.
zogo.BooleanSchema(value interface{}): Validates boolean values (true or false).
zogo.StringSchema(value interface{}): Validates string values.
zogo.NumberSchema(value interface{}): Validates numeric values.
