Thanks for the feedback! You are right, the demo currently hangs quite a lot on Firefox, Im pretty sure the issue is actually not related with the component itself, I created a issue on the repo to fix it https://github.com/zzarcon/react-circle/issues/10 :)

Thanks! That already works a lot better.

To further improve things, I would suggest two changes to your webpack config:

1. Use the production version of React. It seems that you are using the slightly slower development version. (In webpack this is done by defining process.env.NODE_ENV = "production" and eliminating dead code afterwards)

2. Stop using webpack in development mode for your deployment. There are 272 eval() calls in your bundle because of this: https://raw.githubusercontent.com/zzarcon/react-circle/c1480...

Both of these things are already taken care of by the production mode in webpack 4.

You are so right!!

Im using an external tool for deploying the site, created a PR there to use production mode, do you think that should be enough? Thanks! https://github.com/zzarcon/ts-react-toolbox/pull/2

It looks like the whole app is re-rendering every frame instead of just having the stroke properties animate: https://perfht.ml/2vEbUc6

runs really fast in nightly however

I think the author already patched it and that's why you're not seeing the same problem. Now it runs faster for me, too. (But HN doesn't allow me to edit my original comment anymore)
