consuming a rest api inside Express: userid not found - node.js

Question

Insprirated on Gettin MEAN I am making my own application. I try to connect to front end to the backend in Express. I copied the text but my console.log still giving me the message 'userid not found'. I think I am pretty close to the finish. Any tips or helpful links are appreciated.
the Usermodel
const userSchema = new Schema({
firstName: String,
lastName: String,
userName: String,
telephone: String,
password: String
});
2. the route in the api
router
.route('/users/:userid')
.get(ctrlUsers.userReadOne);
module.exports = router;
In Postman this get.request works (for example)
http://localhost:3000/api/users/5ad87da47bb05b0594fff5b6
Together with the book I programmed the app/server/controller:
route:
const express = require('express');
const router = express.Router();
const ctrlUsers = require('../controllers/users');
router.get('/users/:userid', ctrlUsers.userInfo);
module.exports = router;
and the controllers. Here my console.log gives 'no userid found'
const request = require('request');
const apiOptions = {
server: 'http://localhost:3000'
};
if (process.env.NODE_ENV === 'production') {
apiOptions.server = 'https://pure-temple-67771.herokuapp.com';
}
/*Get myprofile */
const userInfo = function (req, res) {
const path = '/api/users/${req.params.userid}';
requestOptions = {
url: apiOptions.server + path,
method: 'GET',
json: {}
};
console.log('path ' + requestOptions.url);
request(
requestOptions,
(err, response, body) => {
_rendermyProfile(req, res, body);
console.log(body); // no userid found
});
};
const _rendermyProfile = function (req, res, userDetail) {
res.render('myProfile', {
profile: {
title: 'Mijn profiel',
firstName: userDetail.firstName,
lastName: userDetail.lastName,
email: userDetail.email,
telephone: userDetail.telephone
}
});
};
module.exports = {
userInfo
};

Of course you will get no userid found, because you have a misusage of string literal. Inside your controller, changed from this:
const path = '/api/users/${req.params.userid}';
to this:
const path = `/api/users/${req.params.userid}`;
String literal is only working if you used a back slash `.
Now your App should make a request correctly.
