    Konva.js - Declarative 2D Canvas for React, Vue, and Svelte (konvajs.org)

    I joined a project last year which uses Konva inside an Angular application. It was my first time doing any kind of canvas programming, but the ergonomics of konva can be picked up quite rapidly and I've been enjoying quite a lot.

    We're working on performance-sensitive project, so one lesson we learned is that all shapes listen to all mouse events by default. We didn't even have lots of shapes, but this was enough to have a noticeable performance hit due to all the event handlers being registered. We pivoted to an opt-in approach instead and that fixed most of our problems.



    What is the purpose? React for Canvas tag?


    The site and docs for Konva are conspiciously pleasant and well fleshed out. The "price" link jumpscare is also something I haven't yet seen.


    Looks promising and quite handy for my project
