My bad! Switched over to the github pages fallback. Cloudflare pages isn't suitable because the wasm files (100mb+) exceed the 25mb limit. (i could bypass this with service worker jank but that tends to be fragile). Github Pages also isn't suitable because it doesn't have a native way of sending the coi/coep headers that are required for SharedArrayBuffer to be available. Can also bypass that with service worker jank but I would prefer not to

Cloudflare R3 might suit the scenario better for you in terms of the heavy assets, it's like AWS S3 except for the cool part where you aren't charged for data egress (last I checked! haha)

I'm about to buy Terraria after all these years, just so I can get the assets and check this out. You're cool :)

Oh Terraria is totally worth it, especially when spelunking with friends.

Its better than Minecraft, in my opinion.

The service worker jank, while conceptually hacky, is actually remarkably un-janky and not really noticeable to users! It's very much fire-and-forget unless you also wanted to have another service worker (in which case it's time for suffering; service workers aren't even a little bit composable).

Depending on how well the files compress, you could try: https://developer.mozilla.org/en-US/docs/Web/API/Compression...

btw: this results in a white page on the first load until you manually reload, since the SW has not been loaded yet. May want to force a page reload on the SW install event to fix.

also: this is incredibly cool. thanks for writing this up and sharing!
