How does socket.io-client.connect work?

socket.io-client.connect works by taking one or more arguments that specify the URL of the Socket.IO server and any configuration options.

The function establishes a WebSocket connection to the server, allowing bidirectional communication between the server and the client.

Once the connection is established, the client can send and receive events with the server using the emit and on methods provided by the socket object that is returned by the function.

The emit method allows the client to send events to the server, while the on method allows the client to listen for events from the server.

The resulting socket object can be used for further communication with the server, such as sending and receiving data or subscribing to server-side events.

By establishing a connection to a Socket.IO server, client-side JavaScript applications can interact with server-side resources and provide real-time updates and notifications to users.

const io = require("socket.io-client");

// Connect to a Socket.IO server
const socket = io("http://localhost:3000");

// Send a message to the server
socket.emit("message", "Hello, server!");

// Listen for messages from the server
socket.on("message", (message) => {
  console.log("Received message from server:", message);
});

In this example, we use the socket.io-client library to establish a connection to a Socket.IO server running at http://localhost:3000. We pass the URL of the server as an argument to the io function, which returns a socket object that represents the connection to the server. We then use the emit method of the socket object to send a message to the server with the event name message and the payload 'Hello, server!'. We also use the on method of the socket object to listen for messages from the server with the event name message. When a message is received from the server, the callback function logs the message to the console. The resulting application can communicate bidirectionally with the Socket.IO server, sending and receiving events and data as needed.
