Just dumped Postman noobie question

[pkfox]

Hi all,
having just lost quite a large collection of requests built up over the years on Postman I have finally done what I should have done years ago and dumped Postman
Preamble over
I don't even know if this is the correct place to ask for help but here goes, how can I determine ( I presume in a pre request script ) whether a service is using a certain port on localhost ? In plain English pseudo code

If something is running on localhost:9653 
host = localhost
else
host = other
endif

and how/where can I create/store global vars

Kind regards

Pete Kane

Currently, Bruno doesn't have any native API to check this. But as a workaround, you could do

const resolveHost = async (primaryUrl, fallbackUrl) => {
  try {
    await bru.sendRequest({ url: primaryUrl, timeout: 2000 });
  } catch(e) {
    if (e.code === 'ECONNREFUSED') {
      return fallbackUrl;
    }
  }

  return primaryUrl;
}

const activeHost = await resolveHost('http://localhost:9653', 'https://echo.usebruno.com');

// bru.setVar('host', activeHost);
// bru.setEnvVar('host', activeHost); 
bru.setGlobalEnvVar('host', activeHost);
