Server / Client Hybrid

This page fetches and uses feature flags server-side, then hydrates the client-side GrowthBook instance. This gives you maximum flexibility and performance.

These features were rendered server-side:

  • feature1: OFF
  • feature2: fallback

And these features are rendered client-side:

  • feature1: OFF
  • feature2: fallback

In this example app, feature flag definitions are cached for 60 seconds. For faster updates, you can configure an SDK Webhook in GrowthBook to hit the following route handler: POST /revalidate

Trigger revalidation manually
