I want to auto refresh seconds in my node app-CodePudding

I'am currently working on a web app that shows the local time of a giving timezone, i am using a time zone api, i want a way to refresh the page or recall the api every second so i can update the seconds in my page.

I am working with node and express

I did some researchs and found some ways with socket.io but i am asking on some native node methos that can do the trick.

One way to achieve this would be to use JavaScript to refresh the page every second by using the setInterval function.

setInterval(function() {
  window.location.reload();
}, 1000);

To refresh the page or call an API every second in a Node.js and Express application, you can use the setInterval function from the JavaScript setInterval function.

Here is an example of how you can use setInterval to refresh the page every second:

app.get('/time', (req, res) => {
  setInterval(() => {
    // Send a request to the time zone API and render the response
    request(timeZoneAPI, (error, response, body) => {
      const data = JSON.parse(body);
      res.render('time', { data });
    });
  }, 1000); // Refresh every 1000 milliseconds (1 second)
});

Keep in mind that setInterval can be resource-intensive, as it runs a function repeatedly in the background. It's important to use it carefully and avoid using it for long periods of time or for tasks that are too resource-intensive.
