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 🙏

YaMD5 - Yet another MD5 hasher

I needed an MD5 hasher, and as usual I want small code base, and fast.

Originally found md5-o-matic. It was fast but did not work with Unicode strings. Also, I eventually realized it was really based on code from Joseph Myers, which is itself a javascript adapation of the C language version the reference implementation of MD5 in Appendix 3 of RFC 1321.

Then I found SparkMD5, which works with Unicode strings, but at a steep cost to performance on large input strings. Also, glancing at the code I saw avoidable redundancies causing the code base to be larger than needed.

So from this point I set out to write my own version, YaMD5 (sorry, I am not good with naming projects), of course heavily relying on the original code from Joseph Myers, (with modifications to incrementally improve performance as per profiling), and bits from SparkMD5 -- I started to work from SparkMD5 implementation, so there might be code original to SparkMD5 I kept in a few places (like say, code in md5.end() etc.)

Benefits of YaMD5

Usage

One pass:

YaMD5.hashStr('hello world\n') === "6f5902ac237024bdd0c176cb93063dc4"

Incremental:

var md5Hasher = new YaMD5();
...
md5Hasher.start();
md5Hasher.appendStr('hello');
md5Hasher.appendStr(' ');
md5Hasher.appendStr('world');
md5Hasher.appendStr('\n');
md5Hasher.end() === '6f5902ac237024bdd0c176cb93063dc4';

I don't know what license covers Joseph Myers' code (need to find out). In any case, concerning whatever original code I contributed in there:
