Frontend live-coding via GHCI

"A few months ago, I announced that the GHC wasm backend added support for Template Haskell and ghci. Initially, the ghci feature only supported running code in nodejs and accessing the nodejs context, and I’ve been asked a few times when ghci was going to work in browsers in order to allow live-coding the frontend. Sure, why not? I promised it in the last blog post’s wishlist. After all, GHCJS used to support GHCJSi for browsers almost 10 years ago!".. https://www.tweag.io/blog/2025-04-17-wasm-ghci-browser/
