I liked that it's a full-stack framework. It's easy to use and I can easily integrate it with other frameworks like Angular. I dislike that it's a little bit old and the documentation is not up-to-date. I would suggest to use it if you are looking for a full-stack framework. I was using a front-end framework, Angular. I realized that I had to add some features to my application and I needed to integrate them with my back-end. So I decided to use Vaadin, which is a full-stack framework so it helped me a lot. It's great for creating rich web applications using java which are cross platform compatible like mobile apps as well desktop app too. I have used it since last 7 years but still i feel its not perfect yet so need some more time before we say stop working because of any problems faced by us while developing our product/applications. We developed an e-commerce website where customers could buy products from different categories such as electronics & home appliances etc.,.
