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 🙏

let url = "<audio source url>";

/* Create an instance of an audio player. */
let audioPlayer = new AudioPlayer();
/* Or create it with url, loadHandler and errorHandler. */
let audioPlayer = new AudioPlayer(url, loadHandler, errorHandler);

/** Bind an event handler to the load event. */
audioPlayer.onLoad(loadHandler);

/** Unbind an event handler from the load event. */

/** Unbind all event handlers from the load event. */
audioPlayer.clearLoad();

/** Bind an event handler to the error event. */
audioPlayer.onError(errorHandler);

audioPlayer.removeError(errorHandler);

/** Unbind all event handlers from the error event. */
audioPlayer.clearError();

/** Bind an event handler to the start event. */
audioPlayer.onStart(startHandler);

/** Unbind an event handler from the start event. */
audioPlayer.removeStart(startHandler);

/** Unbind all event handlers from the start event. */
audioPlayer.clearStart();

/** Bind an event handler to the stop event. */
audioPlayer.onStop(stopHandler);

/** Unbind an event handler from the stop event. */
audioPlayer.removeStop(stopHandler);

/** Unbind all event handlers from the stop event. */
audioPlayer.clearStop();

/** Bind an event handler to the pause event. */

/** Unbind an event handler from the pause event. */
audioPlayer.removePause(pauseHandler);

/** Unbind all event handlers from the pause event. */
audioPlayer.clearPause();

/** Bind an event handler to the resume event. */
