Claude Sdk Integration Patterns

This is your reference guide for integrating Claude's API into production TypeScript apps. It covers the practical patterns you'll actually need: streaming responses with event handlers, tool use with Zod validation and automatic execution, proper error handling with retry logic, and multi-turn conversation management. The code examples are complete and production-oriented, showing things like abort controllers for streaming, exponential backoff, and the toolRunner helper that handles the tool execution loop for you. If you're building anything beyond basic one-off API calls, especially chatbots or agents that need streaming or function calling, this walks through the SDK patterns that'll save you from reinventing them.
