Asynchronous setTimeout for server-side operations

Question

Asynchronous setTimeout for server-side operations

I am currently facing an issue with my web server. Whenever a request is made, the server initiates a phone call, waits for 3 seconds, and then checks if the call is still ongoing. I have utilized setTimeout to achieve this functionality, but it seems to block all other connections until the timeout has completed.

// Sample GET request
app.get("/", function(req, res) {
  // Perform an action
  example.makeCall(function() {
    setTimeout(function() {
      // Check the action
      example.checkCall(function() {
        res.status(200)
      })
    }, 3000)
  })
})

I am wondering if there is an alternative method to implement a timeout for requests without interfering with incoming connections?

It seems like there may be an issue with your additional API requests being blocked. Each new API request should initiate a fresh invocation of the callback function on the call stack, rather than waiting for previous functions to complete.

The problem might not necessarily be caused by the setTimeout function blocking the calls. There could be another underlying issue with your phone call API preventing new calls from being made while ongoing calls are in progress.

One potential workaround to consider is introducing a 3-second delay using a promise to bypass any potential blockages:

const waitThree = () => {
  return new Promise(resolve => {
    setTimeout(() => {
      resolve();
    }, 3000);
  });
}

app.get("/", (req, res) => {
  // Perform an action
  example.makeCall(() => {
    waitThree().then(() => {
      example.checkCall(() => {
        res.status(200);
      });
    });
  });
});
