Observable retry on error

this._employeeService.getEmployees()
.pipe(retryWhen((err)=>err.pipe(
delay(1000),
scan((retryCount)=>{
if(retryCount>=5){
throw err;
}
else{
retryCount++;
console.log(retryCount);
return retryCount;
}
},0))
))

this._employeeService.getEmployees()

.pipe(retryWhen(delay(1000)))
.subscribe(..);

In this mode it work : .pipe(retry())

really amazing

good explanation , enjoying this concept well

😐

Excellent! Very clear explanation!

Thanks man! You helped me a lot here!

I was getting some build errors until I updated Visual Studio. I now get no build errors but response comes back as "undefined". I can get all employees to load but when I click on a link to get a single employee, that's when I get "ReferenceError: response is not defined" when using a break point in developer tools and employee details is always emp101 details and no other?

Sir please make a video on angular interview questions as well. We have very less resource on internet and it would be very helpful for the candidates who are preparing for an interview. Thank you in advance.

perfect

Hello Sir,
Control is not going inside err.scan() method. Is there anything I am missing something due to updates of Angular? I have the exactly same code as you have in this video. Thank You

Instead of using scan, u could have also done this:
return error.delay(3000).take(3).concat(Observable.throw("Failed"));
is there any special reason for using scan?

Awesome explanation. I love to watch your videos. Thanks

Very instructive and well explained.
