FAQPage Schema
What are frontend feature flags and how do they streamline safe rollouts?▼

Frontend feature flags are configuration switches that decouple deployment from release. They streamline safe rollouts by enabling canary deployments and targeted feature exposure across client rendering and getServerSideProps without redeploying code.

How do I implement a new feature flag in getServerSideProps and client rendering?▼

To implement a new feature flag, apply lifecycle patterns across server and client rendering. Define the flag in your SDK, integrate it within getServerSideProps for initial load states, and ensure proper overrides and cleanup are planned.

How do I debug feature flag overrides and integration issues in frontend applications?▼

Debug feature flag overrides by applying detection rules and manos integration references to diagnose conflicts. Verify flag states across client rendering and integration points to ensure the SDK evaluates overrides correctly during canary rollouts.

When should I do feature flag cleanup and what lifecycle patterns should I follow?▼

Feature flag cleanup should occur after a rollout completes to remove dead code. Follow lifecycle patterns that enforce detection rules, ensuring flags are evaluated for removal once overrides are no longer needed and integration points are stable.

Does this feature flag guidance apply to canary rollouts and client-side rendering?▼

Yes, the guidance specifically applies to canary rollouts and client-side rendering. It covers integration points across getServerSideProps and client rendering, ensuring proper lifecycle management and cleanup for safe frontend experiments.
