Use of GraphQL technology for web applications

This diploma thesis aims for use of modern technology GraphQL to implement prototype application for employees, projects, and technologies connection. The main goal of this thesis is divided into multiple partial goals which leads to its solution. These goals include description of chosen technologies, creation of application server, implementation of basic modules, connection to external services and definition of key roles. It also includes agile methodology Scrum, that is configured to its needs for the project and future development. Last goal is to compare latency speed with current version of the application. The benefit of the thesis is the implemented prototype which will serve as a core for reconstruction of current solution in the company. This will lead to increase the quality of use for all employees. Thesis is divided into two main sections. First section contains theoretical part such as description of technologies, Scrum methodology and GraphQL. Second section describes the implementation of the solution and iteration progress in Scrum. It contains modules implementation, environment configuration, technical improvements, and methodology management. Final chapter also includes summary of all goals and results of measurement for latency comparison.
