Sending messages from client to server using Spring Websocket STOMP Java

Question

I was going through the documentation available on Internet regarding sending/receiving messages using Spring Websocket STOMP. I could see various examples of sending messages from Backend to frontend (example given below) but don't see any examples to send the messages from frontend to backend.. Can someone please help?

Have you checked the stomp-js documentation? There is a (void) send(destination, headers = {}, body = '') declaration.

Following the client-side code snippet, I can guess you are using the stompjs library for client setup.

Once your stompClient setup, the library offers a send method that you can use the to send messages for a specific messaging destination using the underlying STOMP-protocol SEND frame:

stompClient.send('/queue/some-queue', {}, "Some message");

The above line will send a STOMP message to the /queue/some-queue destination with empty ({}) headers and a Some messsage text.
