In this module, you'll build the backend of a real-time chat application using Node.js and Express. You’ll implement REST APIs, authentication, and data handling, while learning how to structure a backend application with middleware, routing, and a data layer. You’ll also add real-time communication using WebSockets and persist application data using a database. By the end of this module, you’ll have a fully functional backend that supports authentication, messaging, and real-time updates.

In this module, you'll build the frontend for your chat application using React. You’ll learn how React components work, how to manage state, and how to structure a frontend project. You’ll implement routing between pages, connect the interface to backend APIs, handle authentication tokens, and add real-time messaging with WebSockets. By the end of this module, you'll have a fully interactive chat interface that communicates with your backend.

In this module, you'll learn how to prepare your application for deployment. You’ll containerize both the backend and frontend using Docker, configure production environments, and run the application using Docker Compose. You’ll also learn how services communicate inside container networks and how to manage environment variables securely. By the end of this module, you’ll be able to run and deploy your full-stack application using containerized infrastructure.

In this module, you’ll reflect on everything you’ve built during the course and review the complete architecture of your full-stack chat application. You’ll also explore ideas for extending your project with new features and improvements. By the end of this module, you’ll have a clear understanding of how to continue developing and expanding your full-stack JavaScript applications.
