SDKs Reference

Server Side SDKs

Java SDK

In Java, feature toggling is made available through FeatureToggle.java and returns the value of a toggle after resolving the enablement inheritance rules.

import com.marfeel.context.FeatureToggles;
import com.marfeel.enums.FeatureToggle;

if (FeatureToggles.hasFeature(FeatureToggle.YOUR_SUPER_COOL_FEATURE_NAME)) {
   // CODE TO EXECUTE WHEN FEATURE IS ON
}

WARNING

The feature has to be added as java enum in FeatureToggle.java.

JSP SDK

Feature toggles are made available to JSPs code via dali's FeatureTogglesTag which returns the value of a toggle after resolving the enablement inheritance rules

<dali:hasFeature name="YOUR_SUPER_COOL_FEATURE_NAME">
  // CODE TO EXECUTE WHEN FEATURE IS ON
</dali:hasFeature>

If you want to execute code when the feature is not present:

<dali:hasFeature name="YOUR_SUPER_COOL_FEATURE_NAME" value="${false}">
  // CODE TO EXECUTE WHEN FEATURE IS OFF
</dali:hasFeature>

Client Side SDKs

Javascript SDK

Feature toggles are made available to Javascript code via the FeatureEnabler module. The isFeatureOn method is exposed and returns the value of a toggle after resolving the enablement inheritance rules

import { isFeatureOn } from 'featureEnabler';

close() {
 if (this.isOpen) {
  if (isFeatureOn('newUserJourneyEvents')) {
   Metrics.trackCloseLateralMenu();
  }
  close.call(this);
 }
}
