svelte-error-boundary VS svelte-kit-koa-boilerplate

Apparently it's quite a complex problem from what I have gathered. While there are packages like @crownframework/svelte-error-boundary that can guard from initialization-time errors, which I have blogged about, they sometimes don't work with asynchronous errors or errors triggered in child components. So it would actually be huge to have built-in support for error boundaries.

I agree with you error boundaries are a huge omission. You can do basic error boundaries using one of these two packages:

* https://github.com/crownframework/svelte-error-boundary

Thankfully there is a community package available that implements error boundaries! 🤩

- once released and popular, they cease getting frequent updates

Now, yes this is a generalization. It doesn't apply to all of their packages, and not at the same point in time. But there is a pattern there. Some quick diving into the author's Github account, and their more popular repos shows the pattern. It's also clear that this was a choice made by a Svelte contributor to use their own package for "official" support in Svelte Kit.

When it comes to polka itself, I just don't get why a maturing framework like Svelte would choose something whose only real advantage lies in micro-benchmarking porn [1]. Speculation aside, I'm surprised the Svelte team didn't look at that choice through a lens of higher scrutiny. Koa would have been an infinitely better choice in my personal opinion, and there are several community-driven setups [2][3] for it.
