4 Reasons To Use WebSockets for Your Next Project + Example

Now obviously creating new TCP connection for every request is not very performant and HTTP has not been unaware of this. In fact, as part of HTTP/1.1, persistent connections were introduced to alleviate this shortcoming of HTTP. While this just scratches the surface, WebSocket with Spring can be used to build complex chat clients and more. It’s one geared specifically towards real-life production
environments. Using Lightrun, you can drill down into running
applications, including 3rd party dependencies, with real-time
logs, snapshots, and metrics. As always, the writeup is super practical and based on a
simple application that can work with documents with a mix of
encrypted and unencrypted fields.

Additionally, HTTP requests can only flow in one direction—from the client side. There is traditionally no mechanism for the server to initiate communication with the client. The server is unable to send data to the client unless the client requests it first.

Webhooks or polling

Websockets are like a secret channel that lets you speak with your friend immediately and unhindered. It is a powerful technology that can be used in many web applications to provide real-time, bidirectional communication between a client and a server. They are used in various applications, real-time analytics, remote monitoring, notifications, alerts, etc. Their applicability is not limited to these examples, and they can be used in a wide range of applications where real-time communication is needed. In general, it is a powerful and versatile technology that can provide a more interactive and dynamic user experience in web applications.

As with so many other aspects of a given project, the technology that ultimately works best for you may not always be what the general guidance would suggest. Just as with HTTP, you’ll find that a WebSocket has its own set of scenarios that illustrate when it may be the what is websocket used for best choice for your project. Remember our caution at the start of this blog, however, as the following guidance does not take any special messaging protocol into account. APIs are usually a collection of endpoints that clients can call to communicate with the system.

When a WebSocket is typically better

Once the connection is upgraded, the protocol switches from HTTP to WebSocket, and while packets are still sent over TCP, the communication now conforms to the WebSocket message format. Since TCP, the underlying protocol that transmits data packets, is a full-duplex protocol, both the client and the server can send messages at the same time. Messages can be fragmented, so it’s possible to send a huge message without declaring the size beforehand.

• Imagine this technique as an HTTP request that does not get an immediate response, rather the server holds the request for a certain time period, during which it expects an event to happen.
• The advantage of WebSockets is that they enable realtime communication between the client and server without the need for frequent HTTP requests/responses.
• Another aspect of it allows error detection faced by consumers to be reported in real-time.
• Users are so used to of real-time facebook and twitter updates, and that has set very high standards for other web and mobile applications.
