WebSockets: Real-Time Communication for Front-End & Back-End
In today’s hyper-connected world, users expect real-time interactions—whether it's chatting with support, receiving stock updates, or tracking delivery in motion. Traditional HTTP was never built for this level of immediacy. Enter WebSockets —the game-changer for real-time, two-way communication between clients and servers. What are WebSockets?
