Course Topics
The basics of computer networks, web protocols, and markup languages form the foundation for the development of modern web applications. Key concepts such as communication via the Internet using HTTP/HTTPS, the structure of IP networks, and the use of HTML for structuring web pages are covered. In web development, the focus is on usability, accessibility, and responsive design to ensure a barrier-free user interface that can be used on various end devices. Client-side dynamics are implemented using the web scripting language JavaScript in combination with CSS and frameworks like Bootstrap. The design of web applications and web services also includes the planning and modeling of functionalities, data flows, and interfaces. JavaScript (Node.js) is also used for server-side web development, which, together with the Express framework and a database system, enables the processing of user requests and the implementation of basic business logic.

Teaching format
• Lectures • Small exercises and regular assignments • Work in teams

Learning skills • D5.3 - Ability to follow rapid technological developments and to learn about innovative aspects of the latest generation of information technology and systems.

Assessment
The assignments aim at ensuring a continuous interaction with the course content and will be assessed according to correctness and completeness. The project activity aims at assessing how students approach the development of a web-based application and how they interact with each other in order to achieve a common goal. The written exam assesses the acquisition and the understanding of the theoretical knowledge presented during lectures.

Evaluation criteria
Written exam [50%], assignments [25%] and a project [25%]. The project and the assignments are valid for the 3 regular exam sessions within the same academic year. The assignments must be submitted during the semester, and the project can be presented before the written exam of the first exam session or before the second regular exam session on the dates announced at the beginning of the semester. Further details will be provided during the lectures and on the course web page.
