title: Vaadin vs. Bootstrap
body: <p>I am planning to make an application that has views with complex forms and logical validation on the client side. I plan to use AJAX for submits and have some visual appeal.</p>
  
  <p>I want a recommendation from those who have experience developing with Bootstrap and/or CoffeeScript and Vaadin. I have two options:</p>
  
  <ul>
  <li>Using Bootstrap / CoffeeScript and some framework for the server site, such as Play Framework, Rails or Django</li>
  <li>Vaadin</li>
  </ul>
  
  <p>The criterion that concerns me is related to the complications that may arise in the client side JavaScript and/or HTML5 validation as well as in CSS and HTML code to be written using Bootstrap. Is it worth using CoffeeScript over Vaadin in a practically ria app? I see that there are many who have chosen Bootstrap and I'm sure they have their reasons.</p>
  
  <p>Help me with the decision. Some relevant documentation could be helpful, too.</p>
