I started in a enterprise and i know nothing about front end.
This company is kind a messy, and i’m been training to keep their software with vaadin 14.
But there is no pattern, i’d like to organize the code and build a pattern to be follow like a traditional application
front just recive and send data, back and proccess and return data, and about front validations and checks i’d like to keep outside view to be easier refactor the code when it needs.
Could you help me show some content how to use good pratice with vaadin ?
