How to make a response result of module execution, nodejs/express?

Question

JavaScript

Good afternoon! Please tell me why I can not get to the response? (nodejs / express) I'm trying
to write a module that would receive data from another server ... it receives data, it is displayed in the console, but how to make the response be the result of the execution of this module, so that I can send them further to the client?
It doesn't work out how to do it.
Thank you!
The module itself

var request = require('request');
var rp = require('request-promise');

loadData = () => {
  var options = {
    uri: 'http://fake-domen.com/...',
    headers: {
      'User-Agent': 'Request-Promise'
    },
    json: true // Automatically parses the JSON string in the response
  };
  rp(options)
  .then(function (repos) {
    console.log(repos, 'repos');
    return repos
  })
  .catch(function (err) {
    // API call failed...
  });
}

exports.func = loadData;

Answer 1

No way. Neither request nor request-promise can make requests that block an event loop.

Answer 2

loadData = () => {
  var options = {
    uri: 'http://fake-domen.com/...',
    headers: {
      'User-Agent': 'Request-Promise'
    },
    json: true // Automatically parses the JSON string in the response
  };
  return rp(options)
  .then(function (repos) {
    console.log(repos, 'repos');
    return repos
  })
  .catch(function (err) {
    // API call failed...
  });
}

const func = require('./func);
func()
.then()
