Angular 2 Http Timeout

Question

I am having trouble sending a custom error message when HTTP timeout.

Here is a simple example:

return this._http.get(url).timeout(5000, new Error("Error message"));

I saw that everyone is using a new error ("Error Message") , but I get an error message:

The error function expects the type Scheduler. I get this error: An argument of type “Error” is not assigned to a parameter of type “Scheduler”. The SchedulerAction property is missing from the Error type

Answer 1

rxjs 4 . rxjs 5 timeout :

• due: number |
• scheduler: IScheduler ( , Observable )

, - :

return this._http.get(url)
 .timeout(5000)
 .catch(err => {

   if (err.name !== "TimeoutError") {
      return Observable.throw("Timeout has occurred");
   }

   return Observable.throw(err);

});

Answer 2

timeoutWith:

return this._http.get(url).timeoutWith(5000, Observable.throw(new Error("Error message")));

Answer 3

Starting with version rc.5, the timeout no longer accepts the errorToSend argument.
