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 🙏

:gear: Get started

Install

Install using npm

npm install --save vue-audio-visual

for Vue 2 install version 2.5.1

npm i -S [email protected]

Use plugin

Install plugin in main.js:

import { createApp } from "vue";
import App from "./App.vue";
import { AVPlugin } from "vue-audio-visual";

const app = createApp(App);
app.use(AVPlugin);

app.mount("#app");

Then anywhere is your app you can use it like this:

<av-bars src="/static/bach.mp3" bar-color="#CCC"> </av-bars>

Use component

Single component can be imported and used

<script setup lang="ts">
import { AVWaveform } from 'vue-audio-visual'
</script>

<template>
  <AVWaveform src="http://foo.com/music.ogg" />
</template>

Composable functions

Plugin provides composable "use" functions for each plugin component. Actually, each component uses composable function inside. See, for example, line component.

Composable functions use audio and canvas element refs. It is handy when you need full access to audio or canvas elements. In the same time it is easy to use:

<script setup lang="ts">
import { ref } from 'vue'
import { useAVBars } from 'vue-audio-visual'

const player = ref(null)
const canvas = ref(null)
const mySource = "./symphony.mp3"

// composable function useAVBars
useAVBars(player, canvas, { src: mySource, canvHeight: 40, canvWidth: 200, barColor: 'lime' })
</script>

<template>
  <div>
    <audio ref="player" :src="mySource" controls />
    <canvas ref="canvas" />
  </div>
</template>

:gear: API

There are several components that comes with plugin. Here is the list of available plugins:

| Name | Component name | Composable function | | -----------| -------------- | ------------------- | | av-bars | AVBars | useAVBars | | av-circle | AvCircle | useAVCircle | | av-line | AVLine | useAVLine | | av-media | AVMedia | useAVMedia | | av-waveform | AVWaveform | useAVWaveform |

There are props that are common for all components and special props for each component. All props for components' names follow vue specs when using wiht composable functions. Meaning when prop's name is "foo-bar" then in composable function parameter it is expected to be "fooBar".

Common props

AVLine props

Composable function:

function useAVLine<T extends object>(
  player: Ref<HTMLAudioElement | null>,
  canvas: Ref<HTMLCanvasElement | null>,
  props: T,
);

  canvas: Ref<HTMLCanvasElement | null>,
  props: T,

);
