The World Wide Web and its underlying technologies are increasingly gaining importance for the development of interactive Web applications. This course introduces concepts, principles, and methods in current client and server-side Web technologies. Knowledge in basic Web technologies, such as HTML, JavaScript, CSS is recommended. The focus of this course is on emerging Web technologies. These include extensions of Web standards, Web toolkits, and development environments, current backend Web frameworks (e.g., Node.js/Express.js, MongoDB), frontend Web frameworks (e.g., React.js, Material UI, Angular), and a combination of Web technologies (e.g., MERN/MEAN Stack). This course follows a student-centered and project-based learning approach. The presented technologies are further investigated and applied in hands-on sessions as well as small student projects carried out throughout the course.
