Advanced n8n for Developers

Advanced n8n for Developers is the practical, no-nonsense guide for engineers who want to build production-grade automations with n8n. Packed with real-world patterns, complete examples, and hands-on projects, this book teaches you how to design scalable workflows, develop custom nodes, integrate modern AI models (OpenAI, Claude, Hugging Face), and operate n8n reliably in cloud and container environments.

You'll learn to:

• write modular JavaScript logic inside workflows and share reusable utilities;

• handle complex API work-authentication, pagination, rate limits, and GraphQL;

• deploy n8n with Docker/Kubernetes, implement CI/CD, and run multi-instance, queue-based systems;

• automate AI tasks (prompt engineering, chaining, memory) and build intelligent agents;

• instrument observability, error handling, backups, and secure secrets with vaults.

Included are practical projects-from a lead-scoring engine and abandoned-cart recovery to an AI research assistant and multi-system CRM/invoicing sync-each accompanied by code snippets, architecture diagrams, and production tips. Whether you're a backend developer, DevOps engineer, or automation lead, this book turns n8n into a robust, extensible platform that fits real business needs.

Build systems, not just scripts. Ship reliable automations that scale.
