Signals can filter sessions by feature flag values. Use this to compare a
release, experiment, or rollout against the rest of your traffic.
How it works
Lucent reads evaluated flag values from session metadata. Values can come from:
- Lucent SDK user properties
- replay integrations that export feature flag metadata
- imported session metadata added by your application or provider
Lucent filters on the value attached to the session.
Send flags with the Lucent SDK
Pass evaluated flag values into Lucent as user properties.
<LucentIdentify
userId={user?.id}
email={user?.email}
properties={{
featureFlags: {
"new-checkout-flow": flags.newCheckoutFlow,
"pricing-page-redesign": flags.pricingPageRedesign,
"paywall-test": flags.paywallTest,
},
}}
/>
tracker.identify({
id: "user_123",
email: "[email protected]",
properties: {
featureFlags: {
"new-checkout-flow": launchDarkly.variation("new-checkout-flow"),
"pricing-page-redesign": statsig.checkGate("pricing-page-redesign"),
"paywall-test": growthbook.getFeatureValue("paywall-test", "control"),
},
},
});
