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 🙏

A list of disposable email domains

Readme

Disposable Email Domains

A list of disposable email domains (like mailinator.com) commonly used to create temporary accounts. Use this list to detect or block fake accounts during your signup process.

Installation

npm install disposable-domains

Usage

This package exports an array of domains. You can check if an email domain exists in the list:

const disposableDomains = require('disposable-domains');
const emailDomain = 'something.mailinator.com'; 

// Check if the exact domain OR the root domain is in the list
const isDisposable = disposableDomains.some(domain => 
  emailDomain === domain || emailDomain.endsWith('.' + domain)
);

if (isDisposable) {
  console.log('Blocked.');
}

How the list works

The entries in index.json should be treated as domain suffixes.

This means you should block the exact domain match and any subdomain to the left of it (a recursive wildcard match).

  • Matches: mailinator.com
  • Also Matches: sub.mailinator.com, a.b.mailinator.com

Contributing

  1. Install dependencies:

    npm install
  2. Add domains to contributions/index.txt:

    • One domain per line
    • No extra formatting
  3. Build the list:

    npm run process

    This validates, sorts, and deduplicates your entries.
