Issue Assistant

This is an experimental project focuses on practicing Vaadin platform, GitLab Webhook and Spring Security.

From Vaadin official website:

Vaadin Flow is a web framework that allows you to write UI 100% in Java without getting bogged down in JS, HTML, and CSS. If you prefer, you can also create layouts in HTML or with a visual designer.

Your apps run on the server and handle all communication automatically and securely. Building on the strong Java ecosystem, Flow works with your favorite IDEs, tools, and libraries.

I am very excited about writing web app UI with fully OOP, so this project was born to practice this.
