GrowthBook Users

Hey guys,
How are you doing?

I have a question about the server-side instance of the SDK on NextJS.

I saw the example, and it's already working (Server and Client side). (I am not using the flags adapter because I was having an error when I was setting the env variable, it was always forcing me to have the default name of the env vars even if I was passing in the init. It was always saying that it was missing the: GROWTHBOOK_CLIENT_KEY).

1. If I need to check if a feature flag is one, I should always init the Growthbook class, check the feature flag, and then destroy? Can I have one instance as a singleton and import it? Is it a good practice or should I always initiate a new instance?

instantiation should be very quick, and you can check states for all flags if needed. One instance should be enough. You can just update the atttributes as needed

So I can make a singleton that stays a live the whole time. Don't need to instantiate and destroy every time I need, right?
