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 🙏

Vue HTML5 audio visualization components

Overview

An audio spectrum visualizer plugin for VueJS framework. It is built with HTML5 Web Audio API and compatible with all browsers that support HTML5 audio API. It provides several Vue components that allows to draw light and nice visualization for "audio" HTML elements. This plugin is compatible with Vue2 and Vue3 frameworks.

There is a DEMO available.

Component AvLine. Vue template name <av-line>

    <av-line
      :line-width="2"
      line-color="lime"
      audio-src="/static/music.mp3"
    ></av-line>

This will create following element:

AvLine Intro

Component AvBars. Vue template name <av-bars>

    <av-bars
      caps-color="#FFF"
      :bar-color="['#f00', '#ff0', '#0f0']"
      canv-fill-color="#000"
      :caps-height="2"
      audio-src="/static/bach.mp3"
    ></av-bars>

This will create following element:

AvBars Intro

Component AvCircle. Vue template name <av-circle>

    <av-circle
      :outline-width="0"
      :progress-width="5"
      :outline-meter-space="5"
      :playtime="true"
      playtime-font="18px Monaco"
      audio-src="/static/bach.mp3"
    ></av-circle>

This will create following element:

AvCircle Intro

Component AvWaveform. Vue template name <av-waveform>

    <av-waveform
      audio-src="/static/bar.mp3"
    ></av-waveform>

This will create following waveform element:

AvWaveform Intro

Component will pre-load audio content and generate clickable waveform.

Component AvMedia. Vue template name <av-media>

    <av-media
      :media="mediaObject"
    ></av-media>

This will create following media element:

AvMedia Intro

Install and setup

Install using npm

npm install --save vue-audio-visual

Enable plugin in main.js:

import Vue from 'vue'
import AudioVisual from 'vue-audio-visual'

Vue.use(AudioVisual)

Example of usage in App.vue or any other Vue component:

  <av-bars
    audio-src="/static/bach.mp3">
  </av-bars>

API

There are three components that comes with plugin: av-line, av-bars, av-circle.

There are a lot of props available to configurate each component. The only mandatory "prop" to pass to component: audio-src. Prop audio-src value should contain URL to media file. Example:

audio-src="http://example.com/media/song.mp3"

Plugin will generate "audio" to control media playback and "canvas" element for visualization.

Another way is to link to existing Vue element using "ref-link" property. When "ref-link" property is set, then "audio-src" property is ignored.

<audio ref="foo" src="music.mp3"></audio>
<av-bars ref-link="foo" />
<av-line ref-link="foo" />

However, it will reference only parent component elements.

There are props that are common for all components and special props for each component.

Common props

Common events

AvLine props

AvBars props

AvCircle props

AvWaveform props

AvMedia props

Please note that common pros are not usable for that element.

Vue component example with media from user device.

<template>
  <audio ref="player" controls />
  <av-media :media="media" />
</template>
<script>
export default {
    name: 'HelloWorld',
    data() {
        return {
            media: null
        }
    },
    mounted () {
      const constraints = { audio: true, video: false }
      navigator.mediaDevices.getUserMedia(constraints).
        then(media => {
          this.media = media
          this.$refs.player.srcObject = media
        })
    }
}
</script>
