How to perform bi-directional communication between client and server

I want to take three inputs on the frontend- start_val, end_val, and increment_val and post these values to the backend in real time. On the server I want to perform some operation and send it back to client.

I'm confused on how to proceed.

Example Input - start_val = 10, end_val = 50, increment_val = 10( This s taken from the client side .

Output = [10, 20, 30, 40, 50] returned back to the client from the server
