Web Application Development

The goal of the thesis was to make research to obtain the knowledge required for the development of a web application. This includes the study of JavaScript, React, Next.js, PostgreSQL and other frameworks and technologies. Another goal was to apply the knowledge gained during the research for creating a full-stack web application. The thesis includes a description of the research carried out and a description of the practical solutions taken during the development of the application. The theoretical part describing the research carried out includes a description of the server- and client-side technologies for development on JavaScript. This includes not only a description of the language and its specifications in general, but also a description of the technologies needed to create a web application. A description of the methods of storing data and publishing the application was also given. The practical part of the thesis describes how these technologies have been applied to create a web application. Particular attention in this part was paid to technical problems that arose during the development and their solution. The result of the thesis was a fully functional application for compiling and administering a grocery list. The application was created using technologies studied during the research and described in the thesis
