Show HN: Socket-call – Call socket.io events like normal JavaScript functions

Hello HN,

I built a Typescript library (named socket-call, for lack of a more sexy name) whose goal is to be able to call socket.io events as regular functions.

So you declare your server-side like so:

  ...
  const listenEvents = (services: UserServices) => ({
    // Add your events here, the name of the event is the name of the function
    login: async (username: string) => {
      services._socket.data.user = { username };
      console.log(`User ${username} logged in`);
      setInterval(() => {
        // Calling an event that's handled client-side
        services.showServerMessage(`You're still logged in ${username}!`)
      }, 1000);
      return `You are now logged in ${username}!`;
    },
  });

and then on the client side you call them like normal async Javascript functions (and you can also create client-side event handlers):

  ...
  const user = socket.addNamespace<UserEmitEvents, UserListenEvents>(
    '/user'
  );
  
  // Calling an event that's declared server-side
  user.login(username.value).then((message) => {
    console.log('Server acked with', message);
  });
  
  // Handling an event that is sent by the server
  user.showServerMessage = (message) => {
    console.log('Server sent us the message', message);
  }

I use this library for my own projects and would be interested to receive feedback about it :-)
