OpenAI API and GPT Integration in JavaScript

Modern web applications are increasingly powered by intelligent language models, making natural language processing an essential skill for developers. This course introduces you to integrating OpenAI APIs into your JavaScript projects, starting from foundational concepts and moving toward production-ready implementations. You will understand how to select and query language models to build smarter applications that can summarize, translate, and analyze text. What you'll learn: Understand core OpenAI API concepts, model families, and pricing structures; Configure API authentication and safely manage environment variables in Node.js; Construct effective prompts using system, user, and assistant message roles; Handle API responses, manage token limits, and implement streaming text outputs; Implement modern vector embeddings and semantic search patterns for smarter retrieval; Practice error handling and rate-limit management to ensure application stability. We begin with essential terminology, setup procedures, and basic API calls, before progressing to structured prompt engineering and integration strategies. This text-based course is designed for JavaScript developers who are new to AI integration and want to build a solid foundation without needing prior machine learning experience. Take your first step toward building intelligent, AI-driven web applications today.
