Where does the 3KiB come from?

[webstrand]

I've looked all over the place, and the closest I could find after brotli-ing preact.min.js at 4KiB. Is it just out of date, or is there a ultralight bundle that actually that small pre-compression?

It's out of date. We should really update it to 4kB as it hovered around that size for a while now as we have kept adding compatibility fixes. There are some plans how to get that down to something <4kB again, but doing so would be a breaking change. That's the reason we've held off on doing so.

Looks like currently it's around 4.7kB, not counting preact/hooks, which adds another 1.5kB.

Also, https://preactjs.com/guide/v10/switching-to-preact says that preact/compat adds ~2kB, but the same link as above shows 4.1kB for preact/compat on top of the 1.5kB for preact/hooks which it depends on. In other words, the implication is that preact/compat is 5kB total (3+2), but really it's 10.3kB total.

Preact is a phenomenal library and worth its larger size compared to ancient versions, but yeah, it would be good to update those docs to reflect current numbers.

Feel free to PR the compat size to our docs, happy to bump that up to ~4.2kb.

Hooks are a bit of an issue though, we don't include them in the main marketing size as they're completely optional but compat, being side-effectful, can't drop them at the moment.
