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 🙏

PubSub RPC

test

A generic RPC mechanism for Pub/Sub transports based on MsgPack

Supports NodeJS and modern browsers.

Installing

$ yarn add @akiroz/pubsub-rpc

Why not JSON-RPC?

Native binary support for passing large binary payloads.

Mechanism

  1. Callee subscribe to topic
  2. Caller subscribe to topic/${base64(id)}
  3. Caller publish to topic with a binary id (default 16 byte) in the payload
  4. Callee calls RPC handler with params in the payload to get result or error response
  5. Callee publish response to topic/${base64(id)}
  6. Caller unsubscribe from topic/${base64(id)}

API

See tests for a basic use case that simply uses an EventEmitter as the Pub/Sub mechanism.
