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.

@moecorp/moelog-core

The microkernel of MoeLog: ring buffer, scope, hooks, deduplication and MLWP serialization.

Do not install this directly. It is the shared piece; what you use in an application is @moecorp/moelog-node or @moecorp/moelog-bun.

What it does

It is the only environment-agnostic package: it touches neither node:* nor the DOM. Everything that happens at capture time lives here, and it is written to cost as little as possible:

Pre-allocated ring buffer with a hard memory bound. When it fills up it sacrifices the oldest event of the lowest severity — a debug log never displaces an error.
The stack is not parsed at capture time. The raw Error is kept and processed on the deferred path, once the thread is free. That is the difference between ~0.03 ms and ~0.4 ms per event.
Fingerprint deduplication (FNV-1a over a normalized message): 200 identical errors arrive as one.
Zero third-party dependencies.

License

Note that this SDK is imported into your application, so the AGPL's copyleft reaches further here than it would for a server-only project. If that is a problem for your use case, open an issue: a permissive license for the SDKs with AGPL kept for the server is under consideration.
