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 🙏

dnscmp

NPM Version

Command-line tool for benchmarking and comparing DNS resolution times across DNS providers.

Usage

npx dnscmp
# Cloudflare (1.1.1.1): 3.42ms
# Google (8.8.8.8): 7.81ms
# Quad9 (9.9.9.9): 12.50ms

Results are sorted fastest-first. Each provider is tested 10 times across 3 domains (example.com, example.org, example.net). Providers with multiple IPs are all tested; only the fastest is shown. Providers that fail to respond show failed.

npx dnscmp 1.1.1.1 9.9.9.9        # test specific IPs
npx dnscmp -f resolvers.txt       # test from a file (one IP per line)
npx dnscmp --defaults 9.9.9.9     # default providers plus an extra IP
npx dnscmp --help                 # show all options

Development
