What is the use of WebSocket API ?

The client and servers use this data for negotiation and are used in the early WebSocket handshakes. PubNub is a real-time communications platform that provides the foundation for authentic virtual experiences, like live updates, in-app chat, push notifications, and more. The building block structure of our platform allows for extra features like https://deveducation.com/ Presence, operational dashboards, or geolocation to be incorporated. PubNub also makes it extremely easy to scale, especially compared to socket frameworks like Socket.io or SocksJS. In a nutshell, WebSocket is a realtime web technology that enables bidirectional, full-duplex communication between client and server over a persistent connection.

This process of keeping the backend and frontend in realtime sync is frequently achieved using low-latency, bidirectional WebSockets. There are, for example, solutions like Firebase that offer a realtime database that can push updates to clients over WebSockets. WebSockets are a bidirectional communication method, allowing for multiple responses from a single server request. WebSockets are also mostly used for client-server communication, while webhooks are mostly used for server-server communication.

When should you use WebSocket?

For most companies today, standard connection requests are no longer sufficient. After the handshake, the channel is kept open, allowing for almost continuous communication. The server can independently send data to the client without the client having to request it. If the server has new information, it sends this to the client without any need for a specific request from the client side.

It’s based on TCP and is often used for apps and services that want real-time notification capabilities. We make it easy to build realtime experiences like live chat and multiplayer collaboration for millions of users. With WebSockets, there’s no need for multiple HTTP requests and responses. The advantage of WebSockets is that they enable realtime communication between the client and server without the need for frequent HTTP requests/responses.

What is a WebSocket API?

Think, for example, of features like multi-user live polls and quizzes. Whenever a user votes in a poll, this event may be recorded in a database. And whenever there’s an update to the DB, the change needs to be it education propagated to all other connected clients. WebSockets should be used over HTTP requests whenever latency needs to be the lowest amount possible so users receive notifications on events as fast as they happen.

With this API, you can send messages to a server and receive event-driven responses without having to poll the server for a reply. It’s important to note that web-sockets chat applications require a server to maintain a persistent connection with each connected client. As the number of connected clients grows, this can put a strain on server resources.

This brings benefits such as reduced latency, and improved performance and responsiveness of web apps. By adding the real-time capabilities of WebSockets, Moralis gives developers the capabilities they need to build cutting-edge blockchain-based applications. Developers and teams no longer have to worry about how to build and maintain their backend infrastructure.

Once the communication link establishment and the connection are opened, message exchange will take place in bidirectional mode until connection persists between client-server. If anyone of them (client-server) dies or decide to close the connection is closed by both of the party. The way in which socket works is slightly different from how HTTP works, the status code 101 denotes the switching protocol in WebSocket. Regardless of your IaaS and configuration, you must configure your load balancer to send the X-Forwarded-For and X-Forwarded-Proto headers for non-WebSocket HTTP requests on ports 80 and 443.
