Chapter 74: Async Patterns & Streaming

Build async muscle for AI interactions. This chapter creates an async-streaming skill to handle Promises, cancellation, SSE, and streaming transports for chat/voice agents.

Goals​

  • Use Promises/async-await with robust error handling
  • Handle streaming via SSE and streamable HTTP transports
  • Implement cancellation (AbortController) and retries/timeouts
  • Capture patterns in a reusable async/streaming skill

Lesson Progression​

  • Async foundations and Promise patterns
  • Streaming with SSE and HTTP streaming APIs
  • Cancellation, retries, and timeouts
  • Capstone: streaming client utilities; finalize the skill

Outcome & Method​

You finish with reusable streaming utilities and an async/streaming skill ready for later chapters and capstones.

Prerequisites​

  • Chapter 73 fundamentals
