Hi team 👋, I'm currently looking at integrating GB into a NextJS app router project for the first time so this is possibly an easy question, hoping someone could help clear some things up. My aim is to forward assigned variations from server components to the client in order to push these to the datalayer (following docs.growthbook.io/lib/react#…), but I opted for using the

GrowthBookClient

to prevent having to recreate a GrowthBook instance on every request (as far as I understand). This instance does not seem to have the

getDeferredTrackingCalls

method on it however. Is there a way to access the assigned variations from

GrowthBookClient

instead, or should I look to use

GrowthBook

instances? If the latter, what is the recommended way of sharing this instance between nested server components to minimize prop drilling?

Hi @quick-midnight-66579 good morning! Yep, that's expected.

getDeferredTrackingCalls()

is available on the JS SDK

GrowthBook

instance, not

GrowthBookClient

. For Next.js App Router / Server Components, I'd follow the SSR docs you linked and create a

GrowthBook

instance server-side for the request, evaluate the flags, then call:

getDeferredTrackingCalls()

and pass that small tracking payload to a client component that pushes to the dataLayer.

Many thanks, that clears it up 😃

My absolute pleasure to assist 🌻
