is

Is package provides various validation functions to check the correctness of different types of data. It offers a collection of functions to validate data such as numbers, strings, geographic coordinates, email addresses, e-mail, bank card number, bank account IBAN, phone and more.

Note

The package provides validation functions that do not pre-clean the data. If the validation data needs to be cleaned, it must be cleaned beforehand, for example, using the g package, as g.Weed, g.Trim etc.

Installation

To use the Go Is package in your project, you need to install it using the go get command:

go get github.com/goloop/is

Usage

Here's an example of how to use the Go Is package to validate different types of data:

package main

import (
	"fmt"
	"github.com/goloop/is"
)

func main() {
	// Validate a phone number.
	phoneNum := "+380 (96) 46 200 00"
	if is.Phone(phoneNum) {
		fmt.Println("Valid phone number")
	} else {
		fmt.Println("Invalid phone number")
	}

	// Validate an email address
	email := "test@example.com"
	if is.Email(email) {
		fmt.Println("Valid email address")
	} else {
		fmt.Println("Invalid email address")
	}

	// Validate geographic coordinates
	latitude := 37.7749
	longitude := -122.4194
	if is.Coordinates(latitude, longitude) {
		fmt.Println("Valid coordinates")
	} else {
		fmt.Println("Invalid coordinates")
	}

	// Output:
	// Valid phone number
	// Valid email address
	// Valid coordinates
}

This example demonstrates how to use the Go Is package to validate a phone number, email address, and geographic coordinates. You can import the github.com/goloop/is package and call the corresponding validation functions for the specific data you want to validate. The functions will return a boolean value indicating whether the data is valid or not.
