What would you recommend doing instead?

Web sockets would probably be easy.

Some web socket libraries support automatic fallback to polling if the infrastructure doesn’t support web sockets.

Do you need bidirectional streams? If so, you should write a bespoke protocol, on top of UDP, TCP or websockets.

If you don't, use GraphQL.

"Write a protocol and GraphQL", god damn it escalates quickly.

Fortunately, there are intermediate steps.

Any suggestions for a good RPC library?

I have had a really good experience with https://connectrpc.com/ so far. Buf is doing some interesting things in this space https://buf.build/docs/ecosystem/

I've used twitchtv/twirp with success. I like it because it's simple and doesn't reinvent itself over and over again.

What about songle directional streams? Graphql streams aren't widely supported yet are they? Graphql also strikes me as a weird alternative to protobufs as the latter works so hard for performance with binary payloads, and graphql is typically human readable bloaty text. And they aren't really queries, you can just choose to ignore parts of the return for a rpc.
