What is WebSocket?
WebSocket is a TCP-based communication protocol used to establish and maintain a continuous, bidirectional connection between a client and a server over the internet. Unlike the traditional HTTP protocol, WebSocket allows real-time and continuous data exchange without the need to establish a new connection for each transmission.
Some key features of WebSocket
Persistent Connection: Once a WebSocket connection is established, it remains open continuously between the client and the server. There's no need to initiate a new connection for each data exchange.
Bidirectional Data: WebSocket enables data transmission from both the client and the server over the same connection. This is suitable for applications requiring real-time communication, such as online games, chat applications, weather data updates, etc.
Good Performance: WebSocket reduces latency in data exchange by maintaining an open connection instead of establishing new connections for each request.
Scalability: Due to the absence of constant connection establishment, WebSocket can handle multiple concurrent requests without creating many new server resources.
Frame-Based Protocol: Data is transmitted in independent frames, making it easier to manage and ensure data integrity.
In summary, WebSocket is a technology that enables continuous and real-time bidirectional communication between a client and a server through a persistent connection. This is extremely useful for building applications that require rapid interaction and updates.
