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 🙏

styles-from-html

Given html, will return all css styles from style tags as a concatenated string, as well as the resulting html with these style tags removed. Useful when you need to pass in css that is separated from html to another library while having declared css rules within embedded html documents (e.g. for request performance optimization).

JavaScript Style Guide

Installation

npm install --styles-from-html
# or yarn add styles-from-html

Why not use cheer.io?

While it is generally frowned upon to use regular expressions for parsing HTML, this library makes a conscious choice to do so anyway, but only for the sole purpose of passing style tags. This results in significant performance improvements. A suite of tests is used to ensure the stability of the implementation. If you feel like there is any reason to use cheer.io or alternative HTML parsers anyway, please create a real world test case that does not resolve with the built-in regular expression.
