Function: compositeRetryDelayGenerator()

Source: AutoRetry.ts

Import

import { compositeRetryDelayGenerator } from '@litert/utils-async';

Signature

function compositeRetryDelayGenerator(opts: IRetryDelayOptions): IRetryDelayGenerator;

Description

Composes a base delay generator with an optional jitter function and an upper-bound cap, returning a new IRetryDelayGenerator. This is the recommended way to build production retry delay strategies.

Parameters

• Parameter opts: IRetryDelayOptions — See IRetryDelayOptions.

Return Value

A new IRetryDelayGenerator that applies jitter and caps the result at opts.maxDelay.

Example

import {
    autoRetry,
    compositeRetryDelayGenerator,
    createExponentialBackoffDelayGenerator,
    fullJitter,
    sleep,
} from '@litert/utils-async';

const genDelay = compositeRetryDelayGenerator({
    delayGenerator: createExponentialBackoffDelayGenerator(1000, 2),
    jitter: fullJitter,
    maxDelay: 30000,
});

await autoRetry({
    maxRetries: 10,
    function: () => fetchData(),
    beforeRetry: async (ctx) => {
        await sleep(genDelay(ctx.retriedTimes));
    },
});
