Original GitHub issue: https://github.com/ProxymanApp/Proxyman/issues/664

Originally assigned to: @NghiaTranUIT on GitHub.

Proxyman version? (Ex. Proxyman 1.4.3)

2.10.0

macOS Version? (Ex. mac 10.14)

mac 10.13

I really need to have ability to delay some responses in scripting. Ideally using Promises. But I was told that's not possible. Maybe there are any workarounds to achieve delays?

It seems that JavaScriptCore from Apple doesn’t officially support Promise.

I will find the way to support fetch api, then you can convert your Promise to fetch and make request asynchronously.

It's not only about fetches but implementing simple delay for response when I want to emulate slow connection for particular request.

Hey @amorphius, let check out this BETA build: https://proxyman.s3.us-east-2.amazonaws.com/beta/Proxyman_2.10.0_Add_Sleep_Func.dmg

Basically, you can use sleep() function to make the current thread sleep synchronously. Please beware that sleep() takes milliseconds as a param.

For instance,

function onResponse(context, url, request, response) {
  console.log("Start sleep");
  
  // Sleep 5 seconds
  sleep(5000);
  
  console.log("Done")
  
  // Done
  return response;
}

I tested and it will delay 5 seconds before returning the Response to my client app 🙌
