Properties

Optional ReadonlydomainScoped

domainScoped?: boolean

ProviderEvents

Readonlymetadata

metadata: ProviderMetadata

Optional ReadonlyrunsOn

runsOn?: Paradigm

Represents where the provider is intended to be run. If defined, the SDK will enforce that the defined paradigm at runtime.

Optional Readonlystatus

status?: S

Deprecated

the SDK now maintains the provider's state; there's no need for providers to implement this field. Returns a representation of the current readiness of the provider.

Providers which do not implement this method are assumed to be ready immediately.

Methods

Optionalinitialize

  • initialize(context?, domain?): Promise<void>

  • A function used to setup the provider. Called by the SDK after the provider is set if the provider's status is NOT_READY. When the returned promise resolves, the SDK fires the ProviderEvents.Ready event. If the returned promise rejects, the SDK fires the ProviderEvents.Error event. Use this function to perform any context-dependent setup within the provider.

    Parameters

    • Optionalcontext: EvaluationContext

      the global evaluation context

    • Optionaldomain: string

      the bound domain, if any

    Returns Promise<void>

OptionalonClose

  • onClose(): Promise<void>

  • A function used to shut down the provider. Called when this provider is replaced with a new one, or when the OpenFeature is shut down.

    Returns Promise<void>

Optionaltrack
