HTTP streaming refers to a method of delivering web content in a continuous, real-time fashion, allowing users to access and view data as it is being transmitted.

Unlike traditional methods where the entire content is sent at once, HTTP streaming breaks down the data into smaller chunks and sends them progressively.

Use cases:

  1. Incremental Response Generation: Server may need to perform complex calculations or access external resources to generate a response. By sending the response word by word, server can avoid the need to wait for the entire response to be generated before sending any information to the user.
  2. Real-Time Updates: SSE allows servers to push updates to clients in real time. Clients receive information as soon as it is available on the server without the need for repeated polling or constant requests.
  3. Compatibility: SSE is supported by modern web browsers without the need for additional plugins or complex configurations. It uses the standard HTTP protocol, and most web servers support it.
  4. Text-Based Payload: SSE uses a text-based payload, which is human-readable and can be easily debugged. The payload is sent in a simple, newline-delimited format, making it accessible and understandable.
  5. Reduced Latency: SSE helps reduce latency in real-time applications. Since updates are pushed to clients instantly, there is minimal delay between the occurrence of an event on the server and its delivery to the client.
