react-konva is a JavaScript library for drawing complex canvas graphics using React. It provides declarative and reactive bindings to the Konva Framework.
It is an attempt to make React work with the HTML5 canvas library. The goal is to have a similar declarative markup as normal React and also a similar data-flow model.
Currently, react-konva is not supported in the React Native environment.
Currently you can use all Konva nodes and shapes as React components and all Konva events are supported on them in the same way.
Note: you can find a lot of demos and examples for using Konva there: https://konvajs.org/. Really, just go there and take a look at what Konva can do for you. You will be able to do the same with react-konva, too. Konva for react-konva is like DOM for React.
Installation
npm install react-konva konva --save |
Comparisons
react-konva vs react-canvas
react-canvas is a completely
different react plugin. It allows you to draw DOM-like objects (images, texts)
on canvas elements in a very performant way. It is NOT about drawing graphics, but
react-konva serves exactly this purpose: drawing complex graphics on a <canvas> element from within
React.
react-konva vs react-art
react-art allows you to draw graphics on
a page. It also supports SVG output. But it has no support of events on
shapes.
react-konva vs vanilla canvas
Vanilla canvases can be faster since react-konva comes with two layers of abstractions: (1) The Konva framework is on top of canvas and (2) React is on top of Konva. For many applications it’s performance is still very good. The purpose of react-konva is to reduce the complexity of your application and to use a well-known declarative way for drawing on canvases.
