node.js module.exports??

Hi I just finished watching this video, https://teamtreehouse.com/library/organizing-your-code-with-require, in this video we are tasked with using module.exports.get = get to extract 'data', however my console is showing lots of errors this is what I have, the following file is called profile.js

//Require https module
const https = require('https')

//Require https module FOR STATUS CODE
const http = require('http')

//Print error messages 
function printError(error) {
  console.error(error.message);
};


//Function to print message to console
function printMessage(username, badgeCount, points) {
  const message = `${username} has ${badgeCount} total badge(s) and ${points} points in Javascript`;
  console.log(message);
}

function get(username) {
try {

 //Connect to the API URL (https://teamtreehouse.com/username.json)
  const request = https.get(`https://teamtreehouse.com/${username}.json`, response => {
  console.log('the status code is ' + response.statusCode);

//Handle responses that are not 200
if (response.statusCode === 200) {
    let body = '';

    //Read the data
    response.on('data', data => {
    body += data.toString();
    });
    response.on('end', () => {
      try {
      //Parse the data
    const profile = JSON.parse(body);
    printMessage(username, profile.badges.length,
      profile.points.JavaScript);
    } catch (error) {
      printError(error);
    }
      //Print the data
    });
} else {
  const message =  `There was an error getting the profile for ${username} (${http.STATUS_CODES[response.statusCode]})`;
  const statusCodeError = new Error(message);
  printError(statusCodeError);
}

  });
//this object has an error object passed into it 
  request.on('error',printError);
   } catch (error) {
    printError(error);
   }
  };
  module.exports.get = get;

this file is called Project.js

// Problem: We need a simple way to look at a user's badge count and JavaScript points
// Solution: Use Node.js to connect to Treehouse's API to get profile information to print out

//Require https module
const https = require('https')

//Require https module FOR STATUS CODE
const http = require('http')

//Print error messages 
function printError(error) {
  console.error(error.message);
};


//Function to print message to console
function printMessage(username, badgeCount, points) {
  const message = `${username} has ${badgeCount} total badge(s) and ${points} points in Javascript`;
  console.log(message);
}

function getProfile(username) {
try {

 //Connect to the API URL (https://teamtreehouse.com/username.json)
  const request = https.get(`https://teamtreehouse.com/${username}.json`, response => {
  console.log('the status code is ' + response.statusCode);

//Handle responses that are not 200
if (response.statusCode === 200) {
    let body = '';

    //Read the data
    response.on('data', data => {
    body += data.toString();
    });
    response.on('end', () => {
      try {
      //Parse the data
    const profile = JSON.parse(body);
    printMessage(username, profile.badges.length,
      profile.points.JavaScript);
    } catch (error) {
      printError(error);
    }
      //Print the data
    });
} else {
  const message =  `There was an error getting the profile for ${username} (${http.STATUS_CODES[response.statusCode]})`;
  const statusCodeError = new Error(message);
  printError(statusCodeError);
}

  });
//this object has an error object passed into it 
  request.on('error',printError);
   } catch (error) {
    printError(error);
   }
  };

  /*
  ForEach iterates over the array and passes each member into a callback
  function, each member would be a username 
  */
  console.log(process.argv);
  const users = ["chalkers","alenaholligan", "davemcfarland"];
  users.forEach((username) => {
    getProfile(username);

 });  

and lastly, this file is called app.js

const profile = require ('./profile,js');

const users = process.argv.slice(2);
users.forEach(profile.get);

// console.log("Hello World!");
// console.error("Oops something went wrong");
// console.dir({name: "Andrew", age: 33 }); //when passing in object,dir prints out the values and keys in a human readable format

can someone please help?

Hi Erik

Before i run this code, theres a few potential solutions that i can see scanning through your code, the main one that stands out to me is the comma.

The first line of your app.js, you use a comma(,) instead of a full stop (.) on profile.js

const profile = require ('./profile,js');

If this doesn't fix your problem can you paste your error message please
