Function promiseWithRetry

Executes an async function with backoff retry logic. If the function fails, it will be retried with increasing delays between attempts.

Throws

The last error encountered if all attempts fail

Example

// With default parameters (3 attempts, 150ms base):
// 1st try: immediate
// 1st retry: 300ms delay (2^1 * 150)
// 2nd retry: 600ms delay (2^2 * 150)
// 3rd retry: 1200ms delay (2^3 * 150)

    Type Parameters

    • T

    Parameters

    • fn: () => Promise<T>

      The async function to execute

    • attempts: number = 3

      Maximum number of retry attempts (default: 3)

    • backoffMs: number = 150

      Base delay in milliseconds for exponential backoff (default: 150)

    • backoffType: "exponential" | "linear" = 'exponential'

      The type of backoff to use (default: 'exponential')

    Returns Promise<T>

    Promise resolving to the function's result
