I am using request module to return values . {code} 

var token;
const request = require('request');
const authKey='Bearer <APPKEY>'
const ContentType='application/x-www-form-urlencoded' ;
var postData={
    'grant_type':'client_credentials'
};
const options = {
    url: '<m/c detils>',
    method: 'POST',
    headers: {
        'Content-Type': ContentType,
        'Authorization':authKey
    },
    body:require('querystring').stringify(postData)
};

module.exports.getAccessToken=request(options, function(errror, response, body){
    console.info("Token is caling");
    // body...


        console.info("inside request module----------------------",JSON.parse(body));
        console.info("response details---------------------",response);
        token= JSON.parse(body).access_token;
       console.info("token1---------------------",token);
       return token;


   })
)

{code}

Here I am able to return value for token ,but same thing if I want to use in another file for eg ::

var token = authtoken.getAccessToken;

I am getting value as undefined ,I have did

var authtoken=require('./utils/Utils.js');

Please help me out here

Your getAccessToken export isn't exporting a function, it's exporting the request result, which is, as Paul commented, not going to be defined.

I suspect what you wanted was to export a function that invokes the request, like this...

module.exports.getAccessToken = callback => request(options, function(error, response, body) {
   token= JSON.parse(body).access_token;
   callback(token);
});

Of course, you'll need to handle errors...

Since 'request' is async, you'd need to modify your code

// file 1
module.exports.getAccessToken = function (cb) {
    request(options, function(errror, response, body) {
        /**
         * do something
         */
        return cb(body.access_token)
    })
}

// file 2
const file1 = require('file1')

file1.getAccessToken(function (token) {
    // ..
})

Also, if you pass json: true in request options, it'll pass you json data in response

Solution provided by iyerrama29 is fine. But you can use Promise also here. Check below link on how to use Promise here.

Node.js promise request return
