    Interface LDServerBaseClient

    A minimal structural interface that any LaunchDarkly server SDK that can be used with createLDServerSession should satisfy.

    This interface decouples the React SDK from the concrete LDClient type in @launchdarkly/js-server-sdk-common, allowing edge SDKs and other custom server client implementations to be used with createLDServerSession.

    • Determines the JSON variation of a feature flag for a context.

      This version is preferred in TypeScript because it returns unknown instead of any, requiring an explicit cast before use.
