Server‑Sent Events (SSE) : Real‑Time Streaming Without WebSockets

Welcome to this Server‑Sent Events crash course! In this beginner‑friendly tutorial, we’ll demystify Server‑Sent Events (SSE) and show you how to stream data from your server to the browser in real time. Traditional HTTP connections require polling the server for updates, but SSE establishes a single HTTP connection that lets the server push events to the client whenever new data is available. This unidirectional approach is part of the HTML5 specification and is supported by the vast majority of browsers. What you’ll learn: The basics of SSE and how it differs from WebSockets and HTTP polling How the EventSource API works and why SSE is easier to implement than WebSockets Real‑world use cases such as live dashboards, notifications and progress indicators. Step‑by‑step code examples using Node.js/Express to build and consume an SSE endpoint. We’ll also look at advantages like automatic reconnection and reduced network overhead, plus limitations such as text‑only messages and connection limits. By the end of this video, you’ll be able to choose when to use SSE instead of WebSockets and build your own real‑time streaming features. Find the code here https://github.com/harshitdynamite/Se...
