I'm curious: Shouldn't my `productionExecutable/index.html` still function properly if I open it directly in the browser locally? Is a hosted server necessary for WebAssembly (WASM)? I had the impression that everything should occur within the browser without the need for a server. :thinking_face:

~Yes, you need a server, like with a regular HTML + JS. When Wasm is added, your HTML loads JS, and that JS in turn loads Wasm.~

I usually click on IDE browser icons at the top, it spins out the server for me.

But *why* does it need a server? Can't JavaScript load WASM locally?

I think I was wrong. The issue is that we are doing the runtime JS `fetch` of a local `.wasm` file, that browsers don’t allow (without a flag, like `--allow-file-access-from-files` in chrome). If we encoded wasm file inside JS, you’d be able to load it locally. It seems that <https://github.com/WebAssembly/esm-integration|ESM integration proposal> could help with loading wasm as well.

Can I add this `--allow-file-access-from-files`  somehow?

I think it would be cool if my WASM app would only run offline completely from a local file. :slightly_smiling_face:
