How can I implement retry logic in Node.js?

You can implement retry logic in Node.js using libraries like 'async' or 'retry'. Would you like an example?

Yes, please provide an example using the 'retry' library.

Sure! First, install the 'retry' library using npm. Then, you can use it like this:

const retry = require('retry');

const operation = retry.operation();

operation.attempt((currentAttempt) => {
  // Your function call here
  someAsyncFunction((err, result) => {
    if (operation.retry(err)) {
      console.log(`Retrying... Attempt ${currentAttempt}`);
      return;
    }
    if (err) {
      console.error('Failed after several attempts:', err);
    } else {
      console.log('Success:', result);
    }
  });
});

What if I want to customize the retry strategy?

You can customize the retry strategy by passing options to the retry.operation() method. For example, you can set the number of retries, delay between attempts, and more.
