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.


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 🙏

Regenerate sets for Unicode properties and values.




regenerate-unicode-properties regenerate-unicode-properties on npm

regenerate-unicode-properties is a collection of Regenerate sets for various Unicode properties.


To use regenerate-unicode-properties programmatically, install it as a dependency via npm:

$ npm install regenerate-unicode-properties


To get a map of supported properties and their values:

const properties = require('regenerate-unicode-properties');

To get a specific Regenerate set:

// Examples:
const Lu = require('regenerate-unicode-properties/General_Category/Uppercase_Letter.js').characters;
const Greek = require('regenerate-unicode-properties/Script_Extensions/Greek.js').characters;

Some properties can also refer to strings rather than single characters:

const { characters, strings } = require('regenerate-unicode-properties/Property_of_Strings/Basic_Emoji.js');

To get the Unicode version the data was based on:

const unicodeVersion = require('regenerate-unicode-properties/unicode-version.js');

For maintainers

How to publish a new release

  1. On the main branch, bump the version number in package.json:

    npm version patch -m 'Release v%s'

    Instead of patch, use minor or major as needed.

    Note that this produces a Git commit + tag.

  2. Push the release commit and tag:

    git push && git push --tags

    Our CI then automatically publishes the new release to npm.
