Read a feature-flag

const {getFeatureFlags, getFeatureFlag, getFeatureFlagBoolean, getFeatureFlagString} = require('sap-cf-features'); // get all feature flags const featureFlags = await getFeatureFlags(undefined, "tenantName"); // get some feature flags const featureFlags = await getFeatureFlags(["feature-1", "feature-2"], "tenantName"); // get one feature flag value const featureFlagValue = await getFeatureFlag("feature-1", "tenantName"); const featureFlagValueBoolean = await getFeatureFlagBoolean("feature-1", "tenantName"); const featureFlagValueString = await getFeatureFlagString("feature-2", "tenantName");

add the feature flag to your nodejs express app
