The paper describes the process of developing a web application that contains audio content. When designing the system, the methodology of OOAP (Object-Oriented Analysis and Design) and the MVC (Model View Controller) design pattern were used. With umbrello, canonical UML diagrams are constructed, describing various aspects of the system being modeled. Based on the diagrams created, the application was implemented using the java programming language. Also, the user interface is made, allowing to demonstrate the capabilities of the application. The developed application should be a multi-page client-server application with the ability to listen to music and create playlists based on their preferences.
