how to put interval on retry call in Angular

The following call makes like around 800 connection in 5 seconds, I want to make a connection every 5 seconds to reduce the number of connections. If I put retry(5) after 5 attempts it will stop and I may not have a successful result in 5 tries, thats why I need a time here I think.

  this.http.get(`api`)
 .pipe(retry())
 .subscribe(s=>{
   //result
  },error=>(error));

I don't know where should I put interval actually as far as I know it should come after subscribe but it seems this approach is not the right way.

rxjs angular

You'd need to use the retryWhen operator with delay operator. Try the following

import { retryWhen, delay } from 'rxjs/operators';

this.http.get(`api`).pipe(
  retryWhen(error => error.pipe(delay(5000))
).subscribe(
  s => { 
    // result
  },
  error => {
    // handle error
  }
);

I have used similar functionality in one of my angualr application and worked out this way. Check if this helps.

this.subscription = interval(5000).subscribe(x => {
// API call goes here...
       
});

This code continously executes for every 5 seconds once and if you want to stop the timer then

this.subscription.unsubscribe();
