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>
