Tips for implementing a delay in HTTP requests using RxJS 6.3.0

When I try to use delay with the HTTPClient object, it gives me the following error:

Cannot invoke an expression whose type lacks a call signature. Type 'Number' has no compatible call signatures.

TypeScript Concerns:

import { delay } from 'rxjs/operators';

this.http.get(url,{params:search})
          .pipe(
              delay(1000),
              map(res => res)
          , catchError((error: any) => {
              return Observable.throw(error)
        }));

Answer №1

Delaying the HTTP response is not possible, but you can postpone the return value by incorporating a delay in your code implementation. Below is an example of how this can be achieved:

this.http.get(url,{params:search})
          .pipe(
              map(res => res),
              delay(1000), 
              catchError((error: any) => {
                 return Observable.throw(error)
              }
           ));
