This tutorial walks you through building a simple AI chat application using React.js, Next.js, and the OpenAI API. It covers setting up the development environment, installing the OpenAI SDK, creating an API route, and building a responsive front-end. The tutorial also includes steps to implement real-time streaming of OpenAI responses for a more interactive user experience.

React.js AI Chat with OpenAI API

Hey there! I created this resource to demonstrate a minimal chat application built with React (on Next.js) that communicates directly with OpenAI’s API.
Next week, I’ll be releasing a follow-up showing how the AI SDK can simplify much of the code.
I wanted to publish this first, because many developers jump straight into using libraries, without really understanding what hooks like useChat are doing under the hood. This tutorial focuses on streaming responses without relying on a library, to give you a clearer picture of how things actually work.
