Course Outline
Introduction to LangGraph and Graph Concepts
- The rationale for using graphs in LLM apps: orchestration versus simple chains
- Understanding nodes, edges, and state within LangGraph
- Hello LangGraph: creating your first executable graph
State Management and Prompt Chaining
- Designing prompts as individual graph nodes
- Transmitting state between nodes and managing outputs
- Memory patterns: distinguishing between short-term and persisted context
Branching, Control Flow, and Error Handling
- Conditional routing and multi-path workflow execution
- Strategies for retries, timeouts, and fallbacks
- Ensuring idempotency and safe re-execution
Tools and External Integrations
- Implementing function/tool calling from within graph nodes
- Invoking REST APIs and external services during graph execution
- Managing structured outputs effectively
Retrieval-Augmented Workflows
- Basics of document ingestion and chunking
- Utilizing embeddings and vector stores (e.g., ChromaDB)
- Achieving grounded answers with proper citations
Testing, Debugging, and Evaluation
- Conducting unit-style tests for nodes and paths
- Leveraging tracing and observability tools
- Performing quality checks: assessing factuality, safety, and determinism
Packaging and Deployment Fundamentals
- Setting up environments and managing dependencies
- Deploying graphs behind API endpoints
- Managing workflow versioning and executing rolling updates
