You send a bunch of bytes (octets) and the other side has to figure out how to accumulate them and break them down into coherent messages. WebSockets are implemented on top of TCP, but raw TCP is stream-based. WebSockets, however, are message-based - this means you send a message and the other side receives a message. Until WebSockets came along, you could only perform HTTP request-response operations within the web browser. That’s true, but TCP is a low-level communication protocol and is not available for web developers in the browser as a web API.Įvery modern web browser supports WebSockets, and every popular backend language has WebSocket server libraries as either third-party modules or standard library modules. What’s the big deal, you ask? We’ve had TCP since the dawn of time for such requirements. WebSockets are a connection-based communication protocols that support full-duplex real-time communication. Our demo will have you build a cool, client-server game of Connect4 with Node on the backend, React+SVG on the frontend, and all of the communication between the server and the clients run over WebSockets.
WEBOTS COMMUNICATE OVER SOCKETS SOFTWARE
Nowadays, modern software development teams tend to develop their web service communications with WebSockets, GraphQL, gRPC, and HTTP/2 over the traditional RESTful pattern. Developers bent over backwards and tried to fit every communication and data exchange requirement into the RESTful pattern. REST also had quite the elaborate conceptual model rooted in resources and verbs.īut, REST wasn’t a perfect fit for every web-based communication problem. It dethroned the old SOAP and its verbose XML in favor of JSON over HTTP. REST was the undisputed champion of web APIs.
