Streaming API Patterns

Overview

Modern applications require real-time data delivery. This skill covers Server-Sent Events (SSE) for server-to-client streaming, WebSockets for bidirectional communication, and the Streams API for handling backpressure and efficient data flow.

When to use this skill:

• Streaming LLM responses (ChatGPT-style interfaces)
• Real-time notifications and updates
• Live data feeds (stock prices, analytics)
• Chat applications
• Progress updates for long-running tasks
• Collaborative editing features
