Vetted Vaadin Coders, Consultants for Hire in Ukraine

It is a framework for creating RIA-web applications developed by the Finnish company of the same name. Unlike Javascript libraries and specific browser plug-ins, Vaadin offers a server-oriented architecture based on Java Enterprise Edition. The framework uses Java as the programming language for creating web content. To display the user interface elements and interact with the server on the client side, Vaadin uses the Google Web Toolkit. Using Java as the only programming language for creating web applications and web content is one of the most important functions in Vaadin. The framework uses the model and certain user interface elements, widgets, which makes it very close to the Java desktop development model using HTML and Javascript. The organization of the data model and widgets allows displaying large amounts of data in the browser without the significant load of RAM and without additional actions from the developer. Vaadin adds additional data validation on the server side: this solves the security problems associated with the possibility of spoofing or Javascript code.

Questions and Answers related to Vaadin Development

What are some pros and cons of Vaadin?

“I’ve worked on several projects using Vaadin. Vaadin 7 removes most of the cons in Vaadin 6. Some pros/cons relevance depend on the actual project. To make a long story short, I will try to highlight just a couple of facts. Vaadin allows you to implement your entire UI layer using an Object Oriented model, so you can use all that OO knowledge out there to design UI components. I’ve found that incorporating new developers is easier if you are using Vaadin, because all they need to learn is Vaadin classes…”

What are the benefits of using Vaadin over plain GWT?

“Vaadin includes a server-side development model that: cuts number of code lines to half by reducing layers one has to implement for user interface and allows you to use any JVM based language for user interface. Increases security by keeping user interface logic in the server and allows synchronous calls to any backend API. Also it allows use of any standard Java libraries and tools for UI layer Does not need Java to JavaScript compilation step that often takes time or makes tooling complicated in GWT projects.”

What are some projects that make use of Vaadin?

“I am currently working on a ticketing system for a big company. The entire application is built using Vaadin. This web application I`m working on (mantaining and adding aditional features) is used by more than 2 000 users everyday ( many support employees). I also have coworkers working on other Vaadin applications such as auditing system wich is used by various departments to examine all kinds of data.”

What are the differences between using Vaadin and traditional Java EE servlet web applications?

“I think there are two important differences: you don’t need to deal with HTML, CSS, nor JavaScript when using Vaadin which means that you can implement the whole presentation layer using OO techniques probably gaining in productivity, ease of reuse of UI components, and incorporation of new developers into the project…”
