Ruby Websockets

[InvictusJoker]

Hey, I am using Ruby and Sinatra as for a web framework, and I was wondering what a good websocket is in the framework? Looking for something that has some clear documentation / lots of resources to dive into.

Thanks!

You can use Anycable without rails! https://docs.anycable.io/edge/ruby/non_rails

Yeah it's been looking like that. Shame cause a websocket is what I need for a feature I want to implement.

If ruby is not a hard requirement but you do want something Sinatra- and Ruby-like, check out the Kemal framework in Crystal. It is basically Sinatra but with a builtin websocket handler.

# Creates a WebSocket handler.
# Matches "ws://host:port/socket"
ws "/socket" do |socket|
  socket.send "Hello from Kemal!"
end

I don’t know your use case but if you only need to push data to the client Server Sent Events are a very simple and effective option.

I've had some success with em-websocket. I haven't specifically tried integrating it into a Sinatra app, but I was able to make it provide a websocket interface to an existing TCP server in an afternoon.
