Interface FlagProvider

Readonlytype

isEnabled

• isEnabled(flag: string, context?: FlagContext): boolean

  Evaluate whether a flag is enabled.

  Parameters

  • flag: string
  • Optionalcontext: FlagContext

  Returns boolean

OptionalisEnabledAsync

• isEnabledAsync?(flag: string, context?: FlagContext): Promise<boolean>

  Optionally evaluate a flag asynchronously, when the backing source can produce a more accurate answer than the cached snapshot.

  Implemented only by providers whose SDK evaluates asynchronously (the LaunchDarkly provider). A provider that omits it is not deficient: the service resolves FlagProvider.isEnabled instead, which for a purely local snapshot is already the correct answer.

  Parameters

  • flag: string

    Flag name

  • Optionalcontext: FlagContext

    Targeting context

  Returns Promise<boolean>

  The evaluated value

Optionalstatus

  Optional status — absent when the provider has no health signal.

  Returns FlagProviderStatus

stop

• stop(): Promise<void>

  Release timers / connections.
