A fun craft project I spun up to test out Webpack5 configurations (notably how the lack of common Node polyfills affects my development flow) and the capabilities of the AnimeJS library.
Clone the repo, install the dependencies by running yarn in the musical-keys directory, and then run yarn start in order to kickstart the webpack-dev-server.
Navigate to the port specified by webpack-dev-server (probably 9000)
and voila you should be able to play the Qwerty Keyboard in your favorite browser.
