Node With Express and Redis

In this course, you’ll get an introduction to Node.js and Express.js. You’ll learn about large language models—including how a general LLM works, OpenAI’s GPT model, and its APIs with Node.js. You’ll also learn about Redis to implement API rate limiting. You’ll then gain hands-on, practical experience via three applied projects. The first involves building a Q&A bot using the PDF document to understand embeddings. The second includes building a YouTube video summarizer app to understand speech-to-text processing using OpenAI’s Whipser model. The final project is tol build a Twitter tweet generator to learn image generation with Redis’s role in managing API rate limits.

After taking this course, you can develop intelligent and scalable applications using OpenAI APIs, Redis, and Node.js.
