TIL: don’t use GitHub Pages for your Compose apps! You can’t configure the cache time there — the default is Cache-Control: max-age=600 ! https://github.com/orgs/community/discussions/11884 So every 10 minutes your cache becomes invalid, and you force users to repeatedly re-download the Wasm bundle. I tried Cloudflare, and it’s exactly what you need. Also free. Configuration is even simpler and it has more features.
