Vaadin pre-releases moved to new repository
We are getting closer to releasing our next minor release, 7.6. There has already been 7 alpha pre-releases and we hope to call them betas in the next couple of weeks. We encourage developers to use, or at least try, our pre-releases when working with projects without strict deadlines. This is an ...
Minimized Vaadin servers for IoT solutions
Trimming down the last bytes of deployment artifact size and server startup time has never really been a top priority for business app developers. These measures just need to be within reasonable values, and are seldom essential things in business applications, neither in development or production ...
Vaadin Spring 1.0.0 is out!
I’m honoured to announce that the beta period for Vaadin Spring integration library has ended and the first stable release, with version number 1.0.0, is now available. Using Vaadin (and plain Java) alone is not the best way to build large business applications. In any non-trivial application, ...

Using DeltaSpike properties for more portable application binaries
I recently wrote an example application to create invoices. In it I used Google’s OAuth2 authentication, which naturally requires application specific API keys and secrets from Google that I cannot share publicly in the demo sources. As OAuth2 was just one thing I wanted to demonstrate, I wanted ...
Implementing sign-in with Google’s OAuth 2 services
Traditionally all public web apps have had their own authentication mechanisms, typically implemented with application specific username-password pairs. The approach is straightforward to set up for web developers, but also infamously difficult to do right (not at all or too weak hashing of ...
JCache, why and how?
Caching is needed in many different kinds of solutions to optimize the application in various ways. Discover what Jcache is and why you need it. Why, where and how could you use it? Caching libraries in the Java ecosystem is almost as common as mosquitoes in Northern Europe. Ehcache, Hazelcast, ...
How we improved the startup time in 7.5
When you are making your web applications for non-intranet usage (or for mobile users via VPN), you cannot emphasize the importance of compression too much. Google’s developer tools will blame you for missing compression and we have written several articles about this previously. Still, we have ...
