Stop Learning Python. Build AI with the Tools You Already Know. Are you a jаvascript or TypeScript developer feeling left behind by the AI revolution? Do you think you need to restart your career as a Data Scientist just to build a chatbot? You don't. The future of Artificial Intelligence isn't just about training models; it's about building applications . And for the application layer, jаvascript is king. Building Intelligent Apps with jаvascript & TypeScript is Volume 1 of the Web AI Series . It is a no-nonsense, theory-first guide designed to transform experienced web developers into AI Engineers using the stack they already love. In this foundational volume, you will break the Python monopoly. You will learn that Node.js is not just an alternative; it is often the superior choice for high-concurrency, low-latency AI orchestration. What You Will Master in Volume 1: The Secure Environment: Set up a production-ready Node.js AI environment that handles API keys securely and adheres to modern ECMAScript standards. The OpenAI API Deep Dive: Move beyond simple tutorials. Understand the HTTP contract, master the official SDK, and handle errors and rate limits like a Senior Engineer. Type-Safe AI with Zod: The biggest risk in AI is unpredictable output. Learn to use Zod to enforce strict JSON schemas, turning hallucinating models into reliable structured data generators. Engineering Prompts: Stop guessing. Learn the engineering principles behind System Prompts, Few-Shot learning, and Chain-of-Thought reasoning to control LLM behavior. LangChain.js Foundations: Master the orchestration layer. Learn how to build modular, reusable components (Models, Prompts, Parsers) and link them into executable Chains. Who This Book Is For: This book is written for Software Engineers , not researchers. If you know React, Node.js, or TypeScript, you are ready. We focus on architecture, design patterns, and production-readiness. The ecosystem has changed. You don't need to switch languages to build the next generation of intelligent apps. You just need the right blueprint. Start your journey into AI Engineering today.
