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 🙏

Euterpe.js Player

A simple, safe AudioContext web music player.

How to use

Full demo at github link

All we need to do is import the player builder and build it

import { MusicPlayerBuilder } from "@euterpe/player";
const audio_el = document.querySelector("#audio")

const music_player_builder = MusicPlayerBuilder(audio_el)

// Builder allows for attaching custom nodes if necessary, eg.
const panning_node = music_player_builder.add_stereo_panner_node()
panning_node.pan.value = -0.4
const wave_shaper_node = music_player_builder.add_wave_shaper_node()
waves_shaper_node.oversample = '4x'

const music_player = music_player_builder.build()

//Next we add a song URL to the Audio Element,
music_player.try_new_song(encodeURI("my_song.ogg"))
//and wait for the user input to resume the AudioContext
document.querySelector("#play")?.addEventListener("click", () => {
    music_player.try_play()
        .then(
            //Easily follow up with what to do next
            () => { console.log("Playing!") },
            (e) => alert("Failed to play, " + e)
        )
})

It's quite easy to give user the control in UI

// Play when user clicks a <button></button>
document.querySelector("#play-button")?.addEventListener("click", () => {
    music_player.try_play()
        .then(() => { console.log("Playing!") }, (e) => alert("Failed to play, " + e))
    })
// Mute when user clicks another <button></button>
document.querySelector("#mute")?.addEventListener("click", () => {
    music_player.mute()
})
// Easily give volume control via <input type="range" min="0" max="1" value="1" id="volume" step="0.01">
document.querySelector("#volume")?.addEventListener("input", (e) => {
    music_player.change_volume(e.target?.valueAsNumber)
})

Euterpe Player also provides functions to easily track the status of playback. It does this via Subscription/Publisher pattern which publishes every frame ( Using requestAnimationFrame()). This allows for always up todate values reflecting on the UI.

// Subscriptions to AudioContext changes, eg. time..
music_player.on_duration_formatted((time) => {
    //time == "4:53, "15:59", "1756:15:59"...
    document.querySelector("#duration-text").innerHTML = time
    //duration but in "0","1.2", "1223.21668181"... format
    document.querySelector("#input-seek-range").max = "" + music_player.get_current_duration()
})
//Keep the current time uptodate but formatted.
music_player.on_time_tick_formatted((time) => {
    //time == "2:52", "10:59:59"...
    document.querySelector("#current-text").innerHTML = time
})
//Keep <input type="range"..> slider uptodate
music_player.on_time_tick((time) => {
    //time == "0","1.2", "1223.21668181"...
    document.querySelector("#input-seek-range").value = "" + time
})
