PhosphorJS is a set of JavaScript packages, written in TypeScript, that provide a rich set of widgets, layouts, events, and data structures. These enable developers to construct advanced, production-quality, desktop-like web applications that would be otherwise impossible using CSS alone.

See the PhosphorJS website for more information.
