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 🙏

Observable streams registry

Readme

What is Observable connection?

It is a registry for observable strams. Features:

  • it manages dependent observables
  • pretend to be small

What it won't do

  • dictate app architechture (hornestly, already does)
  • dictate DOM framework to use (initially developed with Angular 1.x, React is welcome too)

Possible applications

Real-time or polling web apps or applications with many different events to handle.

API draft

Define connection

class MyConnection extends Connection;
const connection = new MyConnection(options);

Define new observable

const Rx = require('rxjs');

const plugin = function userSelection() {
  return new Rx.BehaviorSubject([]);
}
const connection = new MyConnection({
  plugins: {plugin}
});

Reading - Observable subscribtion

connection.userSelection.subscribe(selection => {
  console.log('your selection: ', selection);
})

Writing - Subject next()

const Rx = require('rxjs');

const plugin = function userSelection() {
  const _secretValue = []; // immutable, if you want
  const subject = new Rx.BehaviorSubject(_secretValue);
  subject.add = (item) => {
    // type check if you want
    _secretValue.push(item);
    subject.next(_secretValue);
  }
  return subject;
}
// ...
connection.userSelection.add('foo');
