Usage

Load particles.js and configure the particles:

index.html

<div id="particles-js"></div>

<script src="particles.js"></script>

app.js

/* particlesJS.load(@dom-id, @path-json, @callback (optional)); */
particlesJS.load('particles-js', 'assets/particles.json', function() {
  console.log('callback - particles.js config loaded');
});
