How can I effectively retry observables in RxJS?

How can I effectively retry observables in RxJS?

You can use the retry operator in RxJS to automatically retry an observable when it errors. For example, observable.pipe(retry(3)) will retry the observable up to 3 times.

What if I want to add a delay between retries?

You can use the delayWhen operator along with retryWhen. For instance, observable.pipe(retryWhen(errors => errors.pipe(delay(1000)))) will add a 1-second delay between retries.

Can I customize the retry logic based on the error type?

Yes, you can customize the retry logic by using retryWhen to filter errors. For example, you can check the error type and decide whether to retry or not.

Are there any best practices for using retries?

It's best to limit the number of retries, implement exponential backoff for delays, and ensure that retries don't lead to resource exhaustion.
