The second month of Vaadin Add-on competition was a surprising one. First it seemed that the same names occupied the top 5 list as a month before, but after a few web development blogs noticed the tool the winner of May was clear: Marc Englund with Chrometric.
Chrometric is a tool for Vaadin developers (and eventually for all web developers) to check how your web application works for people with color blindness. Learn more about the tool at enably.com/chrometric
Here is also a short video of Marc describing the features and background of Chrometric:
Updated Instructions for Add-on Users
Based on feedback we have now updated the instructions for developers using Vaadin Add-ons as well as the instructions for add-on authors to publish their stuff at the Vaadin Directory.
Creating Add-ons is Easier Than You think
Also creating add-ons is easier than you might think. The thing is that you might already have a component/widget/tool that might be the add-on everyone is missing.
As you might already know, add-ons are normal jar or zip archives that you can just upload to the Vaadin Directory. The hardest part might be to finding a nice name for it you can live with when it comes more popular than you anticipated. Otherwise, just follow the instructions here.
So, stop wondering and start publishing!
