"Hefty"... for an asset that can easily be cached long term, so it is effectively a one time penalty for a given website, and many web apps will load images larger than this. Certainly, just about any marketing/product page will load more bytes than this in the form of images, let alone videos.

So, "hefty" seems like a bit of an exaggeration to me. All other things equal, lighter is always better, but 266KB for all the functionality SQLite offers isn't that bad, IMO.

On the topic of caching, since SQLite is (intentionally or not) going to be setting an example with their docs and demos[0], I would suggest that SQLite should demonstrate the industry best practices with regards to caching as well. Static assets like WASM and JavaScript should be served with a very high cache duration, and the name of the asset should include a hash of the asset. This way, the site maintainer can update the HTML to reference the new SQLite bundles by the new hash whenever they upload new versions, and browsers will immediately request the new versions, but they will otherwise instantly load the cached version after the first visit whenever there isn't a new version.

That can't work on the documentation site because the wasm file is being served from the Fossil SCM and fossil cannot cache resources which are fetched by name because a new version may be checked in at any given moment (they're currently updated very often: https://sqlite.org/wasm/finfo/jswasm/sqlite3.wasm). Fossil can hypothetically cache resources which are fetched by hash, but that's not a feasible way for us to maintain the documentation on that site.

That makes sense, although these topics could still potentially be mentioned in the documentation.

They're not relevant to the wasm/js deliverables. They're an implementation detail of the server which happens to be serving the related documentation. If you have specific verbiage which you feel would improve the docs in this regard, please feel free to send it. i'm likely to miss most responses in HN, so please use email (stephan at sqlite dot org) or the sqlite forum: https://sqlite.org/forum.

cross-origin caching on the web has been dead for years

doesn't seem possible to do without leaking data

I agree. I said:

> so it is effectively a one time penalty for a given website

which shows that I already acknowledged the demise of cross-origin caching.

Each website the user visits that uses this library has to pay a 266KB penalty once, which isn't that bad. (Well, once, unless the site developer decides to upgrade the library, then the penalty applies once more, but that's expected behavior.)
