Re: [elm-discuss] Support for binary data

[Christophe de Vienne]

Our use-case:

We connect our elm application to a NATS server through a websocket [1]

The protocol is text-based but the payload can be binary. We would like
to switch to protobuf to encode our payloads but cannot do that because
of the elm client. So we stick to json for now.

So the need is to be able to encode/decode data structures to a binary
websocket connection.

Re: [elm-discuss] Elm with one message

[Vlad GURDIGA]

Thank you Peter! 🤓

The third option that you proposed 

 
seems to fit nicer with the shape of my data: multiple nested records. I’ve 
tried it, and, I got something compiling! 😎 
https://github.com/gurdiga/xo.elm/pull/1.

So now my child-module exposes additionally its Msg and its update 
function, which the parent-module uses to wire it up in its own fabric.

Does this look close to what you had in mind? 🤔
