struct CustomJSONSocketServer

  include JSONSocket::Server

  def on_message(message, socket)
    puts message
    result = (message["a"].as_i + message["b"].as_i) * message["b"].as_i * message["a"].as_i
    self.send_end_message({ :result => result}, socket)
  end

end

server = CustomJSONSocketServer.new("127.0.0.1", 1234) # OR CustomJSONSocketServer.new(unix_socket: "/tmp/json-socket-server.sock", delimeter: "µ")
server.listen

client.cr

require "json-socket"
to_server = JSONSocket::Client.new(host: "127.0.0.1", port: 1234) # OR JSONSocket::Client.new(unix_socket: "/tmp/json-socket-server.sock", delimeter: "µ")
result = to_server.send({ a: 12, b: 8})
if (result)
  puts result
end

client.cr with timeouts in seconds

require "json-socket"
to_server = JSONSocket::Client.new(host: "127.0.0.1", port: 1234, read_timeout: 10, write_timeout: 5) # OR JSONSocket::Client.new(unix_socket: "/tmp/json-socket-server.sock", delimeter: "µ", read_timeout: 10, write_timeout: 5)
result = to_server.send({ a: 12, b: 8})
if (result)
  puts result
end
