Being an open source project, our goal at Vaadin has always been to enable contributing to the framework as easily as possible. And we’ve accomplished that quite well - Vaadin wouldn’t be what it is today without your feedback and help.
Everything we do is fully open in our public Trac system and GitHub where you have the chance to follow what we are working on during any minute of the day. The best way to contribute back to Vaadin has been, and still is, by writing a ticket about an issue that has bugged you - preferably with an attached patch to fix the issue.
A couple of years back we also invested heavily in a plug-in architecture for Vaadin and after that launched the Vaadin Directory - the place for you to share your add-ons. The Vaadin Directory today contains over 370 add-ons and the amount of add-ons is growing all the time.
But we’ve been lacking the last missing link: an easy way to give you the freedom to commit directly to the core of Vaadin. We’re happy to announce that using Gerrit we can now extend the review policy, we’ve been using internally, to the entire Vaadin community.
Be a part of the core committers of Vaadin. Start by reading through the Contributing Code article, create your accounts according to the instructions and get started today.
