Everything You Need to Know About Springboot Socket IO

Springboot is a popular Java-based framework used for building web applications. It simplifies the process of building web applications by providing a set of pre-built components that you can use to quickly build and deploy your application. One of the most popular components of Springboot is Socket IO, which provides real-time communication between client and server.

What is Socket IO?

Socket IO is a library that enables real-time, bidirectional, and event-based communication between the browser and the server. It makes it possible to build web applications that require real-time communication, such as chat applications, online gaming, and other similar applications.

Socket IO uses WebSockets as the primary transport mechanism, but it also supports other fallback mechanisms, such as HTTP long-polling, to ensure that the communication between the client and server is always reliable.

Why Use Springboot with Socket IO?

Springboot provides several benefits when used in conjunction with Socket IO. Firstly, it simplifies the process of building and deploying web applications by providing a set of pre-built components that you can use to quickly build your application. Secondly, it provides a robust and scalable platform that can handle high traffic loads and large numbers of users.

When used together, Springboot and Socket IO provide a powerful platform for building real-time web applications that require real-time communication between the client and server.

How to Get Started with Springboot Socket IO?

Once you have set up your Springboot project, you can then add the Socket IO dependency to your project. This can be done by adding the following dependency to your pom.xml file:

<dependency><groupId>com.corundumstudio.socketio</groupId><artifactId>netty-socketio</artifactId><version>1.7.16</version></dependency>

After adding the Socket IO dependency to your project, you can then create a Socket IO server by adding the following code to your Springboot application:

@Configurationpublic class SocketIOConfiguration {@Beanpublic SocketIOServer socketIOServer() throws InterruptedException {
Configuration config = new Configuration();config.setHostname("localhost");config.setPort(9092);
final SocketIOServer server = new SocketIOServer(config);server.start();
return server;}}

Once you have set up your Socket IO server, you can then start building your real-time web application.

Building a Real-Time Web Application with Springboot Socket IO

Building a real-time web application with Springboot Socket IO is relatively easy. Firstly, you need to create a Socket IO client in your web application. This can be done by adding the following code to your HTML file:

<script src="https://cdn.socket.io/socket.io-1.4.5.js"></script><script>var socket = io.connect('http://localhost:9092');</script>

This code creates a Socket IO client that connects to the Socket IO server running on localhost:9092.

You can then use the Socket IO client to send and receive messages from the server. For example, you can add the following code to send a message to the server:

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

And you can add the following code to receive messages from the server:

socket.on('message', function(data) {console.log('Received message: ' + data);});

Using Socket IO, you can build real-time web applications that enable real-time communication between the client and server, such as chat applications, online gaming, and other similar applications.

Conclusion

Springboot and Socket IO provide a powerful platform for building real-time web applications. With Springboot’s pre-built components and Socket IO’s real-time communication capabilities, you can quickly build and deploy real-time web applications that can handle high traffic loads and large numbers of users.
