How To Recover From Errors In Rxjs?

I'm trying to understand how to consume observable sequences and how to recover from errors. My example is a bit contrived but my real implementation is a bit too complex to show h

Solution 1:

If you want to send the request again, you may want to look into retry and retryWhen instead of catch.

catch will use the returned Observable as new "source". See this bin for an example.

retry(When) will "re-subscribe" whenever an error occurs, based on the configuration you pass to the operators. You can find examples and more information here: https://www.learnrxjs.io/operators/error_handling/retrywhen.html
