Is there a way to continuously refresh a variable every minute and utilize it as a criterion?

Question

Is there a way to continuously refresh a variable every minute and utilize it as a criterion?

I need to automatically update a variable maxReq, which keeps track of the number of requests sent. At the beginning of the application, every 60 seconds, the variable should be reset to 100.

getData(URL){
  if(this.maxReq <= 0)
     // wait until this.maxReq is set to 100 again

  // after this.maxReq is set to 100 again return: 
  return this.http.get(URL).toPromise();
}

To achieve this, I must monitor both the time and the variable maxReq. The timer should run independently of everything else, counting down from 60 to 0 from the start of the application to the end. When the timer reaches 0, maxReq needs to be updated and the timer reset to 60 seconds - repeating this process every 60 seconds until the application is closed.

What would be the most effective way to accomplish this task?

Answer №1

let countdown = 60;
let startTime = new Date();
setInterval(()=> {
   const secondsPassed = (new Date() - startTime) / 1000;
   countdown = 60 - secondsPassed;
   if (secondsPassed >= 60) {
      startTime = new Date();
      countdown = 60;
      maxRequests = 100;
   }
}, 1000);

Answer 2

let countdown = 60;
let startTime = new Date();
setInterval(()=> {
   const secondsPassed = (new Date() - startTime) / 1000;
   countdown = 60 - secondsPassed;
   if (secondsPassed >= 60) {
      startTime = new Date();
      countdown = 60;
      maxRequests = 100;
   }
}, 1000);
