There are a ton of web resources for people starting to learn Vaadin, but the most important source of information is still Book of Vaadin - also available online. This is quite understandable, because it is also the reference manual for the framework. Almost as important are the other web resources at vaadin.com - tutorials, forum and Javadocs. If you are interested in interactive learning, check out the online Vaadin webinars and Vaadin trainings. Among external sites stackoverflow.com is clearly the most important source of Vaadin information.
Interestingly enough, the “open source” part of the framework is not leveraged. According to the survey very few people actually consult the framework’s source code.
Stay up to date
Like many active open source projects, Vaadin Framework constantly moves forward. There are major and minor product updates, new documentation, wiki updates and blog posts like this one. We attend events, and post about serious and fun stuff happening all the time and we want to share that with all of you.
According to you, following this blog and our monthly newsletter are the best methods to stay up to date. This is nice feedback to the Vaadin team, as lots of hours and nights go into keeping you up to date with what's going on in the Vaadin community.
Browse survey results
The survey was made online among the visitors of vaadin.com. It does not make sense to analyze everything here, but we've made the results browsable to you online so that you can see what the hundreds of Vaadin developers, just like you, have answered. Check it out online at charts.app.fi and be sure to take part of the next survey in April.
