Expanding in the Prime Radiant

On the expansion page, it is possible to expand, build and deploy applications.


You can select an applicationInstance in the table on the left to open a detailed view. Use the new instance button if you want to create a new ApplicationInstance.

The first tab Expansion will show some info on your ApplicationInstance. For a new ApplicationInstance, only the export button will be enabled, alongside the buttons to view, edit and delete it.

The export button will export the application and related components, settings and expansion-settings to the directory linked to the custom base of the ApplicationInstance.

If we wish to expand this application, we will need to first generate a new expansionSettings. To do this, click on the generate expansionSettings button. This will enable the other buttons:

expansion settings

The Prime Radiant will automatically add nsx-default-stack to the expansion-resources. This will add the base-components, web-styles, expanders etc. to your expansion. (See more)

With the expansionSettings configured, you can now expand and build your application.

Adding new expansion-resources

You can add other expansion-resources by inserting it in the input field below. If the expansion-resource does not appear it the dropdown, you can press enter and it will prompt to add it to the database.


When added, the expansion-resource will be included the next time you press expand.

Overlay button

The overlay button will look for any overlay script in the source-base and execute it.

Alternative Expansion

The expand button also allows some alternative modes:

  • Clean Expand: Removes the expansion directory before expanding. This makes sure nothing remains in the directory that is not expanded or harvested. This may be useful to clean deleted ext files or artifacts generated for a deleted element.
  • Skip Overlay: Expand the application, but skip the overlay phase. This generates the application as if there were no overlays, so you can compare the result with the overlays you have.

Clean Build

Similarly, the build button also allow you to perform a Clean build, which will execute mvn clean package.


The Prime Radiant has built in functionality to deploy your application locally in order to review and test it.

Select the application instance you want to deploy and go to the deployment tab. Here you can press request deploy to create a new ApplicationDeployment instance.

new deployment

Next, edit the instance and set the deploy-base. By default, there are a number of deploy-bases for each application server type. It’s best to use a deploy-base with only one application.

set deploybase

Once the deploy-base is set, the deploy actions are enabled. For the first deployment, it’s best to execute them in order.

  • Generate Deploy Configuration: Generate config files that are specific to your application. This includes, among other, the data-sources for each component.
  • Prepare: Clean the deploy-base and copy the configuration files from the previous step to the deploy-base.
  • Do Start/Stop: Start or stop the application

Once configured the application can be started and stopped without having to reconfigure. However, when you add a new component to your application, you should repeat the first two steps to make sure the configuration is correct.

If the application is live, you can open the login page by following the link in the table.
