Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

📦 Installation

Install globally via npm:

npm install -g domain-lookup

Or using yarn:

yarn global add domain-lookup

Or install it in a Node.js project:

npm install domain-lookup

🚀 Usage

🔍 Check a Single Domain in CLI

You can check the availability of a single domain using the following command:

domain-lookup google.com

If the domain is available, you will see:

✅ google.com is Available!

If the domain is not available, you will see:

❌ google.com is Not Available!

📂 Checking Multiple Domains at the Same Time in CLI

You can check multiple domains at once by providing a .txt file containing a list of domain names.

Step 1: Create a .txt File

Create a text file (e.g., domains.txt) and list the domains you want to check, one per line:

google.com
mywebsite.net
randomdomain.org
example.io

Step 2: Run the Command

Run the following command to check all domains listed in the file:

domain-lookup -f domains.txt

Step 3: Get the Results

After running the command, you will see an output like this:

✅ mywebsite.net is Available!
❌ google.com is Not Available!
✅ randomdomain.org is Available!
❌ example.io is Not Available!

📌 This allows you to quickly scan multiple domains without having to check them one by one! 🚀


📜 Using in a Node.js Project

Install the package

npm install domain-lookup

Import the module

const { checkDomain, checkDomainsFromFile } = require("domain-lookup");

Check a single domain

checkDomain("example.com")
  .then(() => console.log("Check complete!"))
  .catch(err => console.error("Error:", err));

Check multiple domains from a file

checkDomainsFromFile("domains.txt")
  .then(() => console.log("Batch check complete!"))
  .catch(err => console.error("Error:", err));

📌 You can now use domain-lookup in any Node.js project! 🚀
