This final thesis explores the key aspects of the web application development with a focus on Angular and PHP Laravel technologies. The purpose of this work is to analyse the advantages of these technologies and methods of their application in creating high-quality web applications. Within the scope of the thesis, Angular and PHP Laravel technologies are analysed in detail. Angular, as a framework for building client-side web applications, enables the development of scalable and dynamic user interfaces. Fundamental concepts such as components and directives are examined, as well as methods of data binding. On the other hand, PHP Laravel, as a backend framework, is explored for its support of server-side web application development, including Object-Relational Mapping (ORM) and routing. The practical part of the thesis involves the development of a web application that demonstrates the concepts of Angular and PHP Laravel. The application consists of a separate frontend and backend that communicate via HTTP REST services. The frontend allows users to interact with the application, while the backend manages the logic and data processing. The research results highlight the benefits of using Angular and PHP Laravel in web application development. Angular facilitates the rapid and structured development of the frontend part of the application, while PHP Laravel simplifies the creation of robust server-side functionalities. The combination of these technologies facilitates integration and web application development. Additionally, the research points out the challenges and advantages of microservices architecture in application development, especially in the context of modularity and scalability. Microservices enable the decomposition of an application into smaller, independent services, contributing to better flexibility and scalability.
