The native API for Canvas elements is pretty good, but Konva is a popular abstraction that sits on top and provides a more structured way to work with shapes, styling, events, animations, and more (lots of demos with code). It also has extra integration libraries for Vue, Svelte, and React.
Konva is a powerful HTML5 Canvas JavaScript framework for creating interactive 2D graphics in web applications. It supports animations, drag-and-drop, high-quality exports, and integrates with frameworks like React and Vue. Widely used by companies like Meta and Microsoft, Konva offers a robust API for managing complex shapes and interactions. Learn more at konvajs.org or explore the source code on GitHub.
