tldify

tldify is a Go package that extends the functionality of the standard net/url package by adding support for parsing URLs into additional fields such as Subdomain, Domain, TLD (Top-Level Domain), and Port. It is designed to simplify URL parsing when you need finer granularity beyond the default URL structure.

This package is inspired by go-tld by @jpillora.

Features

• Parse URLs into components like subdomain, domain, TLD, and port.
• Support for ICANN-managed TLDs using golang.org/x/net/publicsuffix.
• Similar API to net/url for easy integration into existing projects.

Installation

To install tldify, use go get:

go get github.com/cyinnove/tldify

Usage

Here's an example of how to use tldify:

package main

import (
	"fmt"
	"github.com/cyinnove/tldify"
)

func main() {
	url, err := tldify.Parse("http://sub.example.co.uk:8080/path?query=1")
	if err != nil {
		fmt.Println("Error:", err)
		return
	}

	fmt.Println("Subdomain:", url.Subdomain)
	fmt.Println("Domain:", url.Domain)
	fmt.Println("TLD:", url.TLD)
	fmt.Println("Port:", url.Port)
	fmt.Println("ICANN:", url.ICANN)
}

Output:

Subdomain: sub
Domain: example
TLD: co.uk
Port: 8080
ICANN: true

tldify exposes a single main function Parse, which mirrors net/url.Parse but returns an enriched URL struct:

func Parse(s string) (*URL, error)

URL Struct

The URL struct embeds the standard net/url.URL and adds the following fields:

• Subdomain: The subdomain portion of the URL.
• Domain: The domain portion of the URL.
• TLD: The Top-Level Domain (TLD) portion of the URL.
• Port: The port specified in the URL (if any).
• ICANN: A boolean indicating whether the TLD is an ICANN-managed public suffix.

Inspiration

This package was inspired by go-tld, a powerful tool for extracting domains and TLDs from URLs.
