Sketch will automatically handle resizing & scaling of the on window resize. It will automatically scale according to the device's devicePixelRatio, unless you specify otherwise. Sketch is a small canvas utility that creates a element, appends it to the DOM, sizes it to the window, and initializes a 2D context. Note: the Sketch class assumes you're animating with a 2D context if you want full control over your animation loop (or want to use a different context), use the Sync class on its own. Upon instantiating an instance of an extended Visualizer, its Sync instance will automatically begin pinging Spotify for your currently playing track. Sync keeps track of your currently playing Spotify track and provides an interface to determine the current active interval of each type ( tatums, segments, beats, bars, and sections) in addition to the active volume. The Visualizer class contains two class instances – Sync and Sketch. Import Visualizer from './classes/visualizer' export default class HelloWorld extends Visualizer
