When will I have access to the lectures and assignments?

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

What will I get if I subscribe to this Specialization?

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Is financial aid available?

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.

By the end of this course, learners will be able to explain real-time communication concepts, configure a NodeJS development environment, construct a browser-based chat interface, and implement a fully functional multi-user real-time chat application using Socket.IO.

This hands-on case study guides learners through the complete lifecycle of building a real-time chat application with NodeJS. Starting from application planning and environment setup, the course progresses through server configuration, browser rendering, and user interface creation before moving into real-time, multi-user communication. Learners gain practical experience implementing Socket.IO for bidirectional messaging, broadcasting messages across users, managing usernames, and handling connection and disconnection events. The course emphasizes incremental development, allowing learners to clearly understand how each component contributes to the final solution. Unlike theory-heavy courses, this program focuses on practical implementation using a single, evolving codebase, reinforcing real-world development workflows. By completing this course, learners will not only understand how real-time systems work but also gain a reusable foundation they can extend with advanced features, improved user interfaces, or scalability enhancements in future projects.

Module details

This module introduces learners to the fundamentals of building a real-time chat application using NodeJS. It covers the conceptual overview of real-time communication, project environment setup, and essential server configuration. Learners will also implement basic server-to-browser rendering and design the initial chat user interface, establishing the foundational components required for real-time interaction.
