Publisher's Synopsis
Mastering LangChain & LangGraph, 2nd Edition: Build Intelligent Agent Workflows with Ease
The ultimate hands-on guide to building production-ready AI agent systems with LangChain and LangGraph - now fully updated and expanded.
In the fast-evolving world of large language models (LLMs), developers need more than just powerful APIs - they need robust frameworks for orchestration, context management, tooling, and evaluation. Mastering LangChain & LangGraph, 2nd Edition delivers just that: a complete blueprint for building intelligent, modular, and secure agent workflows that scale to real-world applications.
Whether you're creating document assistants, RAG pipelines, or multi-agent systems, this book walks you through every critical concept - from prompt engineering and memory to graph workflows, retrieval, evaluation, and deployment.
What's inside:
- Foundations of LangChain and LangGraph, with real-world architecture breakdowns
- Dynamic prompt strategies, chain types, and context management
- Powerful LangGraph workflows with conditional routing, loops, and multi-agent coordination
- Building RAG pipelines with vector stores like Chroma, Pinecone, and Weaviate
- Deployment at scale using Docker, Kubernetes, and CI/CD automation
- Secure design: API key management, compliance (HIPAA, GDPR), and audit logging
- Domain-specific agent blueprints for finance, healthcare, and enterprise search
- A capstone project: full end-to-end system with monitoring, evaluation, and continuous improvement
New in this edition:
- Fully updated for the latest LangChain and LangGraph APIs
- Advanced topics: QLoRA fine-tuning, prompt evaluation with LangSmith, risk governance
- Expanded appendices with CLI/API cheat sheets, glossary, and resource directories
- CI-ready code samples and a GitHub repo with production templates
Whether you're a developer, data scientist, or AI systems architect, this book provides the practical knowledge and patterns needed to confidently design, deploy, and maintain powerful agentic AI workflows.
Build smarter. Automate faster. Deploy with confidence.
