Documentation

You can find TypeDoc generated documentation for Webvs on the website. The documentation for the Main class is a good place to start.

Installation

npm

For use with package bundlers, Webvs is available on npm as webvs. Install using

npm install webvs

and import in your code and initialize as follows

import Webvs from 'webvs';
const webvs = new Webvs.Main(....)

CDN

You can also embed webvs.js directly from unpkg CDN.

<script src="https://unpkg.com/webvs/dist/webvs.js"></script>

or for a minified version

<script src="https://unpkg.com/webvs/dist/webvs.min.js"></script>

This script exposes a Webvs global which you can use to initialize like so new Webvs.Main(...).

Usage

A typical usage involves creating an Analyser from your music source (e.g. Webvs.WebAudioAnalyser to use an audio tag or song url as a source) and initializing an instance of Webvs.Main with it. The main object serves as the primary interface or controlling the visualization. e.g.

const analyser = new Webvs.WebAudioAnalyser();
const webvs = new Webvs.Main({
    canvas: document.getElementById("canvas"),
    analyser: analyser,
    showStat: true
});
webvs.loadPreset({
  "clearFrame": true,
  "components": [
      {
          "type": "SuperScope",
          "source": "WAVEFORM",
          "code": {
              "perPoint": "x=i*2-1;y=v;"
          },
          "colors": ["#ffffff"]
      }
  ]
});
webvs.start();
analyser.load("music.ogg");
analyser.play();
