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 🙏

aframe-p2p-component

WORK IN PROGRESS demo

A component for A-Frame that enables sharing and updating objects with multiple peers over p2p WebRTC.

Built on top of unsigned-swarmlog, a WebRTC swarm that swarms around a hyperlog, an append-only Merkle DAG that replicates based on scuttlebutt logs and causal linking.

The A-Frame objects created with the A-Frame inspector persist in memory via memdb but could be altered to use leveldb if desired.

Note that substack's original swarmlog is intended to be a cryptographically-secure means of ensuring a publisher to a hyperlog is who they say they are. aframe-p2p-component uses a fork of this project that ignores the cryptographically-secure signing aspect of swarmlog, assuming that small teams of trusted individuals will be using this component to collaboratively build A-Frame scenes and objects without any servers.

CAVEATS: Be warned that not all objects are working just yet.

WARNING!: Physics and animation will trigger position and rotation changed events very frequently. The updating to hyperlog is de-bounced but nevertheless, it is NOT recommended that you use physics or animation with this component at this time.

API

| Property | Description | Default Value | | -------- | ----------- | ------------- | | signalhub| the signalling server url which is required for the peers to find each other | https://signalhub.mafintosh.com | | topic | the topic (id) of the p2p channel the peers will be swarming in | 'mytopic' |

NOTE: HTTPS seems to be necessary sometimes for the signalhub property value.
