What is @smithy/util-retry?

@smithy/util-retry is a utility package designed to provide retry functionality for operations that may fail and need to be retried. It is part of the Smithy framework, which is used by AWS SDK for JavaScript. This package helps in implementing retry strategies, handling transient errors, and ensuring that operations are retried according to specified policies.

What are @smithy/util-retry's main functionalities?

Standard Retry Strategy

This feature allows you to use a standard retry strategy for operations that might fail. The `StandardRetryStrategy` class provides a simple way to retry operations with a default policy.

const { StandardRetryStrategy } = require('@smithy/util-retry');
const retryStrategy = new StandardRetryStrategy();

async function fetchData() {
  try {
    const result = await retryStrategy.retry(() => {
      // Your operation that might fail
      return fetch('https://api.example.com/data');
    });
    console.log('Data fetched successfully:', result);
  } catch (error) {
    console.error('Failed to fetch data:', error);
  }
}

fetchData();

Custom Retry Strategy

This feature allows you to create a custom retry strategy by extending the `StandardRetryStrategy` class. You can override the `shouldRetry` method to implement custom logic for determining whether an operation should be retried.

const { StandardRetryStrategy } = require('@smithy/util-retry');

class CustomRetryStrategy extends StandardRetryStrategy {
  shouldRetry(error) {
    // Custom logic to determine if the operation should be retried
    return error.statusCode === 500;
  }
}

const customRetryStrategy = new CustomRetryStrategy();

async function fetchData() {
  try {
    const result = await customRetryStrategy.retry(() => {
      // Your operation that might fail
      return fetch('https://api.example.com/data');
    });
    console.log('Data fetched successfully:', result);
  } catch (error) {
    console.error('Failed to fetch data:', error);
  }
}

fetchData();

Exponential Backoff

This feature allows you to implement exponential backoff for retrying operations. By providing a custom `delayDecider` function, you can control the delay between retries, increasing it exponentially with each attempt.

const { StandardRetryStrategy } = require('@smithy/util-retry');
const retryStrategy = new StandardRetryStrategy({
  delayDecider: (delayBase, attempts) => Math.pow(2, attempts) * delayBase
});

async function fetchData() {
  try {
    const result = await retryStrategy.retry(() => {
      // Your operation that might fail
      return fetch('https://api.example.com/data');
    });
    console.log('Data fetched successfully:', result);
  } catch (error) {
    console.error('Failed to fetch data:', error);
  }
}

fetchData();
