WASM is not needed.

The author explicitly states that he likes to write Go and that’s why he picked it in this example, which in my opinion makes this article more interesting. The main benefit is that the 'local server' within the service worker mimics the 'real server,' which effectively means you only have to write the code once.

But I generally agree that a 10MB download on first load is not something that I’d be happy to serve to users, especially to those who are using their mobile network.
