In the final paper, a web-application was created for interactive learning of Croatian literature and checking knowledge from it. The users of the application are students, teachers and administrators. The content from which students learn is divided by literary periods. To make it easier to find a topic for study, a term search engine has been implemented. Students select the desired literary period and review the learning content. For each literary period, they have the option to participate in the discussion group for that period. In addition to the content itself, solving quizzes created by teachers also helps learning. Quizzes can be publicly available to everyone or only to a particular class, and the teacher who created the quiz decides about it. To access a privately available quiz, enter a unique code that connects to the quiz. For each quiz, teachers have an overview of the analytics and an insight into who solved the quiz and what result they achieved. Content is added and edited by system administrators via text editing tools. Logging into the system is optional for students, but mandatory for teachers and administrators. The application was created in the JavaScript programming language using the React library and in the C# programming language using the .NET Core framework. The PostgreSQL database was used for the data repository.
