Websocket revolution in communication

Websockets are a new technology that revolutionizes communication on websites. Since the introduction of the REST architecture (Representational State Transfer), it has been used to transfer data between the client and the server. However, websockets come with a new approach to real-time communication that opens the door to new possibilities and a potential replacement for REST. In this article, we'll look at websockets, their benefits, and how they can replace traditional REST communication.

What are websockets?

Websockets are a communication protocol that enables real-time bi-directional communication between a client and a server. Unlike REST, which works on a client-server and request-response basis, websockets maintain a persistent connection between the client and the server. In this way, it is possible to send and receive data immediately without the need to constantly query the server.

Advantages of websockets

Real-time communication: Websockets enable immediate data transfer in real time. This means that information can be sent and updated instantly without having to repeatedly send requests to the server. This is very useful for applications that require fast data synchronization, such as chat applications, live updates, stock trading, and more.
Low Latency: Websockets reduce the latency of client-server communication. Since the connection between the client and the server is permanent, data can be sent and received immediately without delay. This improves the user experience and enables a faster response to events.
Resource conservation: REST requires the client to repeatedly send requests to the server and the server to respond to them. This can be resource intensive, especially with a large number of users. Websockets use fewer resources because they maintain a persistent connection
Flexibility: Websockets are very flexible and allow communication in different formats such as JSON, XML or binary data. This allows a simple and efficient exchange of various types of information between the client and the server.
Scalability: Websockets are designed to be easily scalable. Thanks to their low resource requirements and permanent connection between client and server, a large number of concurrent connections can be efficiently managed. This is important for applications with a large number of users where high scalability is required.

REST replacement

Websockets have the potential to replace traditional REST communication in several areas:

Real-time applications: If you need to create an application with real-time functionality, such as chat, notifications, live updates or collaborative tools, websockets are an excellent choice. With their ability to send and receive data in real-time, you get a response without delay, which is impossible to achieve with REST.
Data synchronization: Websockets allow easy data synchronization between different clients. This is very useful for applications where it is necessary to ensure that all users have access to current and the same data in real time.
Interactive Web Pages: Websockets enable the creation of interactive Web pages where data can be updated immediately and respond to user actions. This delivers an improved user experience and increases engagement.

Websockets bring new possibilities in communication on websites and have the potential to replace the traditional REST architecture. With their ability to send and receive data in real time, low latency, flexibility and scalability, they provide advantages for applications that require real-time communication and interaction with users.
