How to develop applications

Each application should be developed under independent modules (including backend code and front-end code)

...

• META-INF/services/org.apache.eagle.app.spi.ApplicationProvider: support to dynamically scan and load extensible application provider using java service provider.

• webapp/app/apps/${APP_TYPE}: if the application has web portal, then it could add more web code under this directory and make sure building as following in pom.xml 

  Code Block
  <build> <resources> <resource> <directory>src/main/webapp/app</directory> <targetPath>assets/</targetPath> </resource> <resource> <directory>src/main/resources</directory> </resource> </resources> <testResources> <testResource> <directory>src/test/resources</directory> </testResource> </testResources> </build>

...

Test Applications

• Extend org.apache.eagle.app.test.ApplicationTestBase and initialize injector context
• Access shared service with @Inject
• Test application lifecycle with related web resource. 

@Inject private SiteResource siteResource;
@Inject private ApplicationResource applicationResource;


// Create local site
SiteEntity siteEntity = new SiteEntity();
siteEntity.setSiteId("test_site");
siteEntity.setSiteName("Test Site");
siteEntity.setDescription("Test Site for ExampleApplicationProviderTest");
siteResource.createSite(siteEntity);
Assert.assertNotNull(siteEntity.getUuid());


ApplicationOperations.InstallOperation installOperation = new ApplicationOperations.InstallOperation("test_site", "EXAMPLE_APPLICATION", ApplicationEntity.Mode.LOCAL);
installOperation.setConfiguration(getConf());
// Install application
ApplicationEntity applicationEntity = applicationResource.installApplication(installOperation).getData();
// Start application
applicationResource.startApplication(new ApplicationOperations.StartOperation(applicationEntity.getUuid()));
// Stop application
applicationResource.stopApplication(new ApplicationOperations.StopOperation(applicationEntity.getUuid()));
// Uninstall application
applicationResource.uninstallApplication(new ApplicationOperations.UninstallOperation(applicationEntity.getUuid()));
try {
   applicationResource.getApplicationEntityByUUID(applicationEntity.getUuid());
   Assert.fail("Application instance (UUID: " + applicationEntity.getUuid() + ") should have been uninstalled");
} catch (Exception ex) {
   // Expected exception
}
