Introduction
WebSocket is a protocol that enables two-way communication between a client and a server. It is a powerful tool that has revolutionized the way we build real-time applications. UseWebSocket is a library that makes it easy to use WebSocket in your applications. In this article, we will explore the various aspects of UseWebSocket and how it can benefit your application.
What is UseWebSocket?
UseWebSocket is a library that provides a simple and easy-to-use interface for WebSocket communication. It is built on top of the WebSocket API and provides a number of features that simplify the process of creating and managing WebSocket connections.
Features of UseWebSocket
- Simple API: UseWebSocket provides a simple and easy-to-use API for creating and managing WebSocket connections.
- Automatic reconnection: UseWebSocket automatically reconnects to the server if the connection is lost.
- Binary data support: UseWebSocket supports binary data transmission.
- Custom headers: UseWebSocket allows you to set custom headers for WebSocket connections.
- Middleware support: UseWebSocket supports middleware, which allows you to modify incoming and outgoing messages.
How to Install UseWebSocket?
UseWebSocket can be installed using npm. To install UseWebSocket, run the following command:
npm install use-websocket --save
How to Use UseWebSocket?
Using UseWebSocket is easy. First, import the useWebSocket hook from the use-websocket package:
import { useWebSocket } from 'use-websocket';
Next, call the useWebSocket hook and pass in the WebSocket URL:
const { sendMessage, lastMessage, readyState } = useWebSocket('ws://localhost:1234');
Now, you can use the sendMessage function to send messages to the server:
sendMessage('Hello, server!');
The lastMessage variable contains the last message received from the server:
console.log(lastMessage);
The readyState variable contains the current state of the WebSocket connection:
console.log(readyState);
Connecting with Custom Headers
You can pass custom headers to the WebSocket connection by passing an options object as the second parameter to the useWebSocket hook:
const { sendMessage, lastMessage, readyState } = useWebSocket('ws://localhost:1234',{headers: {Authorization: 'Bearer token',},});
Using Middleware
You can use middleware to modify incoming and outgoing messages. Middleware is a function that takes a message and returns a modified message. To add middleware, pass an array of middleware functions as the third parameter to the useWebSocket hook:
const { sendMessage, lastMessage, readyState } = useWebSocket('ws://localhost:1234',undefined,[(message) => {return message.toUpperCase();},(message) => {return message + '!';},]);
