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 🙏

Self adjusting interval

Introdution

javascript's setInterval and setTimeout are lacking when trying to build an accurate timer, furthermore, javascript's nature of being idle can throw off your timers even more!

Here comes self adjusting timers to the rescue!

Tested on -

  • Nodejs
  • Browsers
  • React Native

How does it work

Javascript is a scripting language with runs on one process, due to that both setInterval and setTimeout are not accurate because the process can be busy with other stuff.

Setting a traditional interval will very quickly will prove itself inaccurate, in this picture you can see the offset which is produced by these functions

  setInterval(() => { /* Actually called late/early. */ }, 1000);

wrong

This library will calculate the delta between callbacks and will aim to hit your expectation every time, very much like a game stepping machanism (game time accumalation is anotehr library I wrote for that)
right

Also, javascript can be paused on slowed down to a hault (for example when your user exits your react native app, switching between tabs, or even by rendering UI), so instead of running your callback bunch of times for every missed second, your callback gets to run once with a ticks parameter which tells how much to "tick" by
batch

Usage

  • Install
      npm install --save self-adjusting-interval
      # or yarn
      yarn add self-adjusting-interval
  • import and use!
    import setSelfAdjustingInterval from 'self-adjusting-interval';
    
    setSelfAdjustingInterval(ticks => { // number, usually 1 
    // Your code...
    // for example, updating the UI clock with seconds
      addSecondsToClock(ticks);
    }, 1000); // ms
