backoff

backoff(attempt, options?): number

Defined in: src/time.ts:128

How long to wait before retry number attempt, counting from 0.

Retrying on a fixed schedule makes every client in a fleet retry at the same instant; the jitter strategies exist to break that up.

Parameters

attempt

number

options?

BackoffOptions = {}

Returns

number

Example

backoff(0); // 87.3    around 100ms
backoff(1); // 213.9   around 200ms
backoff(4); // 1483.2  around 1.6s, capped by maxDelay

backoff(3, { base: 250, factor: 3, jitter: "equal" });
