Examples

Static delay

const { delayedPromiseRetry } = require('delayed-promise-retry');

(async () => {
  const fn = async () => {
    console.log('trying...');

    throw new Error();
  };
  const retries = 3;
  const retryDelay = 1000;

  try {
    await delayedPromiseRetry(fn, retries, retryDelay);
  } catch(error) {
    console.log(error);
  }
})();

Custom delay

const { delayedPromiseRetry } = require('delayed-promise-retry');

(async () => {
  const fn = async () => {
    console.log('trying...');

    throw new Error();
  };
  const retries = 3;
  const retryDelay = (retryNumber) => retryNumber * 1000;

  try {
    await delayedPromiseRetry(fn, retries, retryDelay);
  } catch(error) {
    console.log(error);
  }
})();

Exponential delay

const { delayedPromiseRetry, exponentialDelay } = require('delayed-promise-retry');

(async () => {
  const fn = async () => {
    console.log('trying...');

    throw new Error();
  };
  const retries = 3;

  try {
    await delayedPromiseRetry(fn, retries, exponentialDelay);
  } catch(error) {
    console.log(error);
  }
})();
