What is WebSocket?

WebSocket is a protocol that provides a bi-directional communication channel between the client and the server. It is built on top of the HTTP protocol and enables real-time communication between the client and the server. WebSocket allows for a persistent connection between the client and the server, which enables real-time data transfer.

What is Spring Boot?

Spring Boot is a framework that helps developers build robust and scalable web applications. It provides a simple and easy-to-use interface that allows developers to quickly develop applications. Spring Boot is built on top of the Spring framework and provides a variety of features that make it easy to develop web applications.

What is React?

React is a JavaScript library for building user interfaces. It is developed by Facebook and is widely used for creating responsive and interactive web applications. React provides a declarative approach to building UI components, which makes it easy to develop and maintain complex applications.

How does WebSocket Spring Boot React work?

WebSocket Spring Boot React is a combination of WebSocket, Spring Boot, and React. The WebSocket protocol provides a bi-directional communication channel between the client and the server. Spring Boot provides a framework for building web applications, and React provides a library for building user interfaces.

The client-side application is built using React, which provides a declarative approach to building UI components. The server-side application is built using Spring Boot, which provides a variety of features that make it easy to develop web applications. The WebSocket protocol is used to establish a persistent connection between the client and the server, which enables real-time data transfer.

Advantages of WebSocket Spring Boot React

Real-time communication: WebSocket Spring Boot React enables real-time communication between the client and the server, which makes it ideal for building applications that require real-time data transfer.
Scalability: WebSocket Spring Boot React is scalable and can handle a large number of concurrent connections. This makes it ideal for building applications that require high scalability.
Efficiency: WebSocket Spring Boot React is efficient and can handle a large amount of data transfer without any performance issues. This makes it ideal for building applications that require high efficiency.
Robustness: WebSocket Spring Boot React is robust and can handle errors and exceptions gracefully. This makes it ideal for building applications that require high reliability.

How to Build a WebSocket Spring Boot React Application

Building a WebSocket Spring Boot React application involves the following steps:

Create a Spring Boot Application: The first step is to create a Spring Boot application using the Spring Initializr. This can be done by selecting the required dependencies and generating the project.
Add WebSocket Dependency: The next step is to add the WebSocket dependency to the project. This can be done by adding the following dependency to the pom.xml file:

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>

Create WebSocket Configuration: The next step is to create a WebSocket configuration class that extends the WebSocketConfigurerAdapter class. This class is used to configure the WebSocket endpoints and message brokers.
Create WebSocket Controller: The next step is to create a WebSocket controller that handles the WebSocket connections. This controller is responsible for sending and receiving messages from the client.
Create React Application: The next step is to create a React application using the create-react-app command. This will generate a basic React application that can be used as a starting point.
Add WebSocket Client Dependency: The next step is to add the WebSocket client dependency to the React application. This can be done by adding the following dependency to the package.json file:

“dependencies”: {
“@stomp/stompjs”: “^6.0.3”
}

Create WebSocket Client: The next step is to create a WebSocket client that connects to the WebSocket server. This client is responsible for sending and receiving messages from the server.
Integrate React Application with WebSocket Server: The final step is to integrate the React application with the WebSocket server. This can be done by adding the WebSocket client to the React application and connecting it to the WebSocket server.

WebSocket Spring Boot React Example

Let’s create a simple example that demonstrates how to build a WebSocket Spring Boot React application.

Create a Spring Boot Application

The first step is to create a Spring Boot application using the Spring Initializr. Follow the steps below to create a Spring Boot application:

Go to https://start.spring.io/
Select the required dependencies
Generate the project

Add WebSocket Dependency

The next step is to add the WebSocket dependency to the project. This can be done by adding the following dependency to the pom.xml file:

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>

Create WebSocket Configuration

The next step is to create a WebSocket configuration class that extends the WebSocketConfigurerAdapter class. This class is used to configure the WebSocket endpoints and message brokers. Follow the steps below to create a WebSocket configuration class:

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends WebSocketConfigurerAdapter {
    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
        registry.addHandler(new WebSocketHandler(), “/websocket”).setAllowedOrigins(“*”);
    }
}

Create WebSocket Controller

The next step is to create a WebSocket controller that handles the WebSocket connections. This controller is responsible for sending and receiving messages from the client. Follow the steps below to create a WebSocket controller:

@Component
public class WebSocketHandler extends TextWebSocketHandler {
    @Override
    public void handleTextMessage(WebSocketSession session, TextMessage message) throws IOException {
        session.sendMessage(new TextMessage(“Hello, ” + message.getPayload() + “!”));
    }
}

Create React Application

The next step is to create a React application using the create-react-app command. Follow the steps below to create a React application:

npx create-react-app my-app
cd my-app
npm start

Add WebSocket Client Dependency

The next step is to add the WebSocket client dependency to the React application. This can be done by adding the following dependency to the package.json file:

“dependencies”: {
“@stomp/stompjs”: “^6.0.3”
}

Create WebSocket Client

The next step is to create a WebSocket client that connects to the WebSocket server. This client is responsible for sending and receiving messages from the server. Follow the steps below to create a WebSocket client:

import Stomp from “@stomp/stompjs”;
const client = new Stomp.Client(“ws://localhost:8080/websocket”);
client.connect({}, () => {
    client.subscribe(“/topic/greetings”, (message) => {
        console.log(“Received message: ” + message.body);
    });
    client.send(“/app/hello”, {}, “John”);
});

Integrate React Application with WebSocket Server

The final step is to integrate the React application with the WebSocket server. This can be done by adding the WebSocket client to the React application and connecting it to the WebSocket server. Follow the steps below to integrate the React application with the WebSocket server:

import React, { useState, useEffect } from “react”;
import Stomp from “@stomp/stompjs”;
function App() {
    const [greetings, setGreetings] = useState([]);
    const client = new Stomp.Client(“ws://localhost:8080/websocket”);
    client.connect({}, () => {
        client.subscribe(“/topic/greetings”, (message) => {
            setGreetings((greetings) => […greetings, message.body]);
        });
        client.send(“/app/hello”, {}, “John”);
    });
    return (
        <div>
            <h1>Greetings</h1>
            <ul>
               {greetings.map((greeting) => ( <li key={greeting}>{greeting}</li>)))}
            </ul>
        </div>
    );
}
