Mastering Node.js 20+ From REST APIs to AI-Powered Backends

Are you ready to go beyond tutorials and build production-grade Node.js applications that scale, perform, and integrate with today's AI-powered systems?
Mastering Node.js 20+ is your complete roadmap to becoming a professional backend engineer - blending modern TypeScript, RESTful architecture, microservices, and LLM integrations in one practical guide.
What You'll Learn Inside
From fundamentals to advanced deployment, every chapter builds real skills through step-by-step projects and hands-on code examples:
* Core Node.js 20+ Mastery - event loop, async patterns, ES modules, worker threads, and performance profiling.
* TypeScript Integration - strongly-typed APIs, modular architecture, and scalable code organization.
* REST & GraphQL APIs - build full CRUD APIs, integrate OpenAPI specs, handle validation, authentication, and rate limiting.
* Microservices Architecture - break down monoliths, set up message queues, and design fault-tolerant systems.
* Security & Optimization - protect against injection, handle secrets, implement secure authentication flows, and optimize for production.
* Deployment & DevOps - automate CI/CD pipelines, containerize with Docker, and orchestrate services with Kubernetes or Serverless.
* AI-Powered Backends - build LLM-enabled APIs using Retrieval-Augmented Generation (RAG), vector stores, and prompt orchestration.
* Testing & Observability - learn integration testing, monitoring, and performance tracing to keep systems reliable.
Who This Book Is For
* Intermediate to Senior Developers who want to move from "building apps" to "shipping production systems."
* Backend Engineers upgrading their stack with TypeScript, microservices, and AI integrations.
* Tech Leads & Startup Builders who need scalable, maintainable, and secure Node.js templates.
* Computer Science Students & Bootcamp Graduates seeking real-world architecture and deployment experience.
Why This Book Stands Out
100% hands-on - each concept includes a runnable project or working codebase.
Focused on Node.js 20+ - no outdated callbacks or legacy syntax.
Includes production templates - Dockerfiles, CI/CD pipelines, testing, and observability blueprints.
Covers modern trends - TypeScript-first APIs, LLM integrations, and cloud-native scaling.
If you want to build backends that scale, perform, and stay relevant in 2025 and beyond, this is your complete guide.
