The performance on my S21 Ultra is pretty bad. Feels like ~40fps and stuttering. Also, it doesn't have mobile interaction for dragging nodes. I can only pan the canvas.



On my phone, with Chrome Android it's smooth and fast, but on Firefox Android it feels about 20fps and isn't great.


Not to detract this component but I can say with certainty that people will be writing Desktop applications with Svelte/React running inside Electron that takes up gigs of ram. It will be interesting to see how this performs in such environment.

Bit off topic but I really dig the clean look and feel of this. Is there anything close in Flutter? Think building this in Flutter might improve performance for your case (running on a high end samsung phone)


I keep hearing this, but I've never figured out why it might be the case, and particularly with Electron over Chrome/FF?

Surely if react/svelte etc are built well they're relatively low processor / compute? When manipulating canvas / images / rich-whatever, I assume graphic accelerated functions would work substantially better than alternatives.


I'm not sure what the issue was, could be the particular browser they are using (Samsung browser is horrible) but I wouldn't be surprised if it runs into performance issues as number of nodes increase.


I'm talking specifically about electron.


Looks great on an S20 Note Ultra FWIW


Runs flawlessly on my Pixel 4 XL
