Pipe Catcherror Angular at Zane Murray-prior blog

Pipe Catcherror Angular. The catcherror is a pipeable operator. In the case of an error thrown in the call to the dataservice it would be caught and handled (simplified the error handling here). Another useful operator is catcherror. This one may seem a bit strange at first, but that's because it's very flexible. Here’s an example of using catcherror to try a different url if the original fails: We want to create an error stream that emits a value when it errors. The only way to get new values out of it is to subscribe again, restarting its execution. Catches errors on the observable to be handled by returning a new observable or throwing an error. It only listens to the error channel and ignores. To do this, we can use the catcherror operator, which catches. To use catcherror operator, we need to import it from the rxjs/operators as shown below. It cannot emit anything else, its life ends. When an observable errors out, it stops completely.
