Get nominated!

How to get nominated for the VCA award? In one word, participate! Vaadin is an open-source project with a big surface area for participation. Here's are some ideas:

  • Report issues on GitHub or provide useful information and feedback on existing issues. If an issue is hard to reproduce and the report doesn't include it already, provide examples, screenshots, or logs.
  • Contribute patches on GitHub. When you find a potential issue that has not been reported, dig into the code. Vaadin is open-source after all! Add a breakpoint and follow the execution of the program to get to the critical part and see if you can find the problem and its solution. Tip: If the bug is in one class, try overriding the class by creating it in your project in the exact same package. No need to even download the whole code.
  • Publish add-ons on the Vaadin Directory. Often, part of your application can be extracted into an add-on that, if legally possible, you can share with other developers. This also helps you to get more eyes on your code which leads to the improvement of your creation.
  • Share your thoughts, ideas, answers to technical questions on the Discord chat.  and presentations for Java User Groups, events, or any other kind of event, you'll find opportunities to share what you have learned and help other members of the community.
  • Share tips or things you learn about Vaadin as you work with it. For example, I recently discovered the ExampleDataGenerator so I wrote an article about it. On a different occasion, I decided to play with the Eclipse IDE and discovered that it had a wizard to create a new Vaadin project, so I tweeted a screenshot. Other developers might find what you share useful or they may share even more things you didn't know!
  • Speak at conferences, Java User Groups, or at your company. Present Vaadin and what you can do with it. Share photos or screenshots of the presentation on social media, or write about your experience on Medium or on your personal blog. Don't hesitate to tag the Vaadin accounts so we can re-share your posts. We are always happy to hear about what developers are doing with Vaadin!
