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 🙏

JavaScript port of TimelineFX particle system

Readme

timelinefx

JavaScript fork of the timelinefx lib.

Allows particle system effects created in the standalone TimelineFX tool to be loaded and run within a browser.

Basic usage:

  • Unzip TimelineFX .eff file containing xml and images.
  • Place those assets where they can be accessed from your javascript.
// Create particle manager and fx library
var particleManager = new ParticleManager( drawSprite, particle limit = 1000, layers = 1 );
EffectsLibrary.init();
EffectsLibrary.load( xml );

// Grab an effect prototype
var effectPrototype = EffectsLibrary.getEffect( "explosion" );
effectPrototype.compileAll();

// Create/spawn an effect instance
var currentEffectInstance = new Effect( effectPrototype, particleManager );
particleManager.addEffect( currentEffectInstance );``

A complete demo can be found here: http://factor43.com/projects/tfx/demo

Fork

This fork brings the timelinefxjs lib to ES6+ syntax & style. Eventually we will include typescript definitions.

There is only one major API change between this fork and gooddoggy's timelinefx, and that is that ParticleManager takes 3 arguments now, the first one being the drawSprite function.
