Build AI Chatbots with React and AI APIs

О курсе

This course teaches you how to build a fully functional AI chatbot application with React and Generative AI APIs. You will connect your app to real AI services, stream responses in real time, and build a multi-chat interface with a sidebar, chat switching, and per-chat history. Every step is practical and hands-on — you will write real code and see results immediately. The course also includes a dedicated module on common React mistakes in JSX, useState, and useEffect — so you can avoid the errors that slow most developers down and write cleaner React code from the start. Throughout the course, you'll explore: React and Generative AI Setup: Set up your development environment, create a React application, and learn how Generative AI APIs work — including pricing models and how to get your first API key. Building a Chatbot UI: Create the app layout, display chat messages, add a text input and send button, and handle message state in the chat. AI API Integration: Connect your chatbot to Google AI (Gemini), OpenAI (ChatGPT), and DeepSeek — and learn how to isolate AI logic for easy reuse and switching between models. Real-Time Streaming: Enable real-time response streaming from Gemini and ChatGPT so messages appear word by word as the AI generates them. Improving User Experience: Add loading states, dark mode, auto-scroll, markdown rendering, auto-resizable text input, and auto-focus to make the chatbot feel smooth and professional. Handling API Issues: Understand usage limits and rate limits, debug broken code, handle API errors gracefully, and display friendly error messages to users. Multi-Chat Sidebar: Build a sidebar that displays all chats, supports switching between them, shows full message history per chat, and includes a "New Chat" button with auto-generated titles. Common React Mistakes: Learn and fix the most frequent mistakes developers make in JSX syntax, useState hook usage, and useEffect hook behavior.
