Hotwire support

[amo13]

Thank you a lot for this amazing project! Finally something actually viable for go.

I'd like to suggest considering to add something like hotwire. It is the new default in Rails and its integration seems to make a lot of sense.

I was thinking that default gRPC support would work better, gRPC manages sockets, and allows for type safe streams, if there is a go library that can compile go structs into .proto code then it would be a big addition to the framework and would greatly improve the frontend to backend communication.

AFAIK gRPC is still not really supported in the browser.

greatly improve the frontend to backend communication.

I definitely want to address this. The current plan is to code generate Typescript definitions based on the controller API that the views reference to ensure type-safety across the network boundary.

Hey @amo13, thanks for your interest in Bud! I wrote something in a HN comment, so I'll pull that in here since the current plan hasn't changed:

Any plans to implement something like Phonenix LiveView? I've never used Go, but from what I've read I suppose it should work really well given Go's concurrency model. (The name "Livebud" gave some hope as well.)

I haven't looked too closely at LiveView yet. I did flip back and forth between going with the Hotwire approach (I guess inspired by LiveView?). It was a tough call, but I ultimately decided to server-render JS. This thought-experiment helped:

• If Ruby could natively render Javascript, would they still choose the Hotwire approach? I concluded no. I don't see the reason to have multiple approaches (HTML over wire, Stimulus), when one solution (SSR + hydration) would suffice. The one solution also happens to be way more familiar to today's frontend developers. I definitely didn't want to make another templating language.

Bud will eventually ship with it's own JS evaluator. Either through https://github.com/dop251/goja or through porting https://github.com/bellard/quickjs to Go (~25kloc of C)
