Type Alias: RetryOptions<T> ​

RetryOptions<T> = object

Defined in: packages/promise/src/types/retry.ts:11

Options for automatic retry mechanism

Type Parameters ​

T ​

T = unknown

Properties ​

retry? ​

optional retry: number

Defined in: packages/promise/src/types/retry.ts:19

Maximum number of retries.

The total number of attempts will be retry + 1.

Default: 1

retryBackOff? ​

optional retryBackOff: "exponential" | "linear"

Defined in: packages/promise/src/types/retry.ts:26

Accepted values:

  • exponential: each subsequent retry delay will be doubled from the last
  • linear: fixed delay between retries Default: 'exponential'

retryDelay? ​

optional retryDelay: number

Defined in: packages/promise/src/types/retry.ts:31

Minimum delay in milliseconds between retries. Default: 300

retryDelayJitter? ​

optional retryDelayJitter: boolean

Defined in: packages/promise/src/types/retry.ts:39

Whether to add a random delay between 0ms and retryDelayJitterMax to the retryDelay.

This helps to avoid "thundering herd" problem when multiple retries are attempted simultaneously.

Default: true

retryDelayJitterMax? ​

optional retryDelayJitterMax: number

Defined in: packages/promise/src/types/retry.ts:47

Maximum jitter delay (in milliseconds) to be added to the retryDelay when retryDelayJitter is true.

A random value between 0 and retryDelayJitterMax will be added to the base retryDelay.

Default: 100

retryIf? ​

optional retryIf: RetryIfFunc<T>

Defined in: packages/promise/src/types/retry.ts:63

Additional condition to be used to determine whether function should be retried.

If retryIf not provided, execution will be retried on any error until the retry limit is reached or a result is received without an exception.

Param ​

The result from the previous attempt, if any.

Param ​

The number of retries that have been attempted so far.

Param ​

The error from the previous attempt, if any.

Expected return values:

  • true: retry will be attempted regardless of error.
  • false: no further retry will be attempted and the last error/result will be returned.
  • void | undefined: retry will be attempted only if there was an error.
