@types/socket.io-client

What is @types/socket.io-client?

@types/socket.io-client provides TypeScript type definitions for the socket.io-client library, which is used for real-time, bidirectional communication between web clients and servers.

What are @types/socket.io-client's main functionalities?

Connecting to a Socket.IO server

This feature allows you to establish a connection to a Socket.IO server. The code sample demonstrates how to connect to a server running on localhost at port 3000.

const socket = io('http://localhost:3000');

Listening for events

This feature allows you to listen for events emitted by the server. The code sample shows how to listen for a 'message' event and log the received data to the console.

socket.on('message', (data) => { console.log(data); });

Emitting events

This feature allows you to emit events to the server. The code sample demonstrates how to emit a 'message' event with the data 'Hello, server!'.

socket.emit('message', 'Hello, server!');

Handling connection errors

This feature allows you to handle connection errors. The code sample shows how to listen for 'connect_error' events and log the error to the console.

socket.on('connect_error', (err) => { console.error('Connection Error:', err); });

Other packages similar to @types/socket.io-client

@types/ws

@types/ws provides TypeScript type definitions for the ws library, which is a simple to use, blazing fast, and thoroughly tested WebSocket client and server for Node.js. It is more low-level compared to socket.io-client and does not provide built-in support for features like automatic reconnection or broadcasting.

@types/sockjs-client

@types/sockjs-client provides TypeScript type definitions for the sockjs-client library, which is a JavaScript library that provides a WebSocket-like object for browsers. It aims to provide a consistent, cross-browser, low-latency, full-duplex, cross-domain communication channel that works in all browsers. It is similar to socket.io-client but focuses more on providing a consistent API across different browsers.

@types/primus

@types/primus provides TypeScript type definitions for the Primus library, which is a flexible and extensible framework for real-time applications. Primus supports multiple real-time frameworks (including Socket.IO, Engine.IO, and SockJS) and allows you to switch between them without changing your application code. It offers more flexibility compared to socket.io-client but may require more configuration.

socket.io-client provides its own type definitions, so you don't need @types/socket.io-client installed!
