  • retry<T>(fn: (() => Promise<T>), maxRetries??: number, timeout??: number | ((currentAttemptCount: number) => number)): Promise<T>
  • Utility to re-run the given promise function until it resolves or until the number of tries was exceeded.

    • Optional timeout: number | ((currentAttemptCount: number) => number) = 0
