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. Basic Web technologies such as HTML, CSS, JSON, JavaScript, etc. are a prerequisite to take this course. The focus of this course is rather on advanced topics in emerging Web technologies. These include extensions of Web standards, Web toolkits and development environments, current backend Web frameworks (e.g. Node/Express, Flask), frontend Web frameworks (e.g. Angular, React), and combination of different Web technologies (e.g. MEAN/MERN Stack, Dash). This course follows a student-centered and project-based learning approach. Web technologies will be presented in the lecture by student groups. The presented technologies are further investigated and applied in hands-on sessions as well as small student projects carried out throughout the course.
