How to transfer data from a controller to a socket io in nodejs

Question

I'm developing a web application that will use React to display data on the client side after receiving it from an API using Node.js as the backend. I've never used socket.io, though.

Sockets.ts

function socket( io ){
    io.on("connection", socket => {
        var socketId = socket.id;
        var clientIp = socket.request.connection.remoteAddress;
        console.log('New connection ' + socketId + ' from ' + clientIp);
        
        socket.on("disconnect", () => {
          console.log("Client disconnected");
        });
      
      });
}

export default socket;

router.controller.ts

export const getData: RequestHandler = async (req, res) => {

  
  const options= {
    method: 'GET',
  };

  const response = await fetch(citybikeurl, options)
    .then((res: any) => res.json())  
    .catch((e: any) => {
      console.error({ error: e });
    });
  
  
  console.log("RESPONSE: ", response);
  res.json(response);
  
}

routes.ts

router.get('/', dataController.getData)

At the moment, I don't know if I'm passing any data from controller.ts to Sockets.ts, and after of this be able to emit the results.
