Vaadin for Heroku

Easily build a Vaadin application and deploy it on Heroku.

Uses Embed for Vaadin to configure and start an embedded tomcat configured to start Vaadin and store session in memcached.

How to use it

Add the dependency to maven:

<dependency>
  <groupId>eu.hurion.vaadin.heroku</groupId>
  <artifactId>vaadin-for-heroku</artifactId>
  <version>0.4</version>
</dependency>

Then make a class with a main method to launch the server;

public static void main(final String[] args) {
    herokuServer(forApplication(YourVaadinApplication.class)).start();
}

By default, the configuration assume you're using the memcache add-on. If you prefer using the memcachier add-on, use

public static void main(final String[] args) {
    herokuServer(forApplication(YourVaadinApplication.class))
            .withMemcachedSessionManager(memcachierAddOn())
            .start();
}

Finally, make a Procfile to point to you class

web:    java $JAVA_OPTS -cp target/classes:target/dependency/* path.to.your.Launcher

For ease of development, another pre-configured server is available:

public static void main(final String[] args) {
    localServer(forApplication(YourVaadinApplication.class)).start();
}

This local server does not require memcached to be running/configured, launch on port 8080 and automatically open a browser. Best way to use it is to make another launcher in your test sources and use it from your IDE.

See hello-vaadin-heroku for a complete example.
