I don't think it's fair to compare the community of a framework which is less than half the age of the ones you are comparing it to, but I agree community is a big one - luckily I've found the Svelte community super helpful, so I've really not suffered at all. As for 3rd party libraries - it's ludicrously easy to integrate anything you want with Svelte. I've built wrappers for Vue and React before, and I can safely say that it isn't necessary for Svelte. Things just work.
