ActiveDirectory Authentication using NODE for Windows SQL 2012 - node.js

Am using node Active directory for validating users. Here is my node code:
const express = require('express');
const async = require('async');
const activedirectory = require('activedirectory');
var underscore = require('underscore');
const ldap = require('ldapjs');
const bunyan = require('bunyan');
const app = express();
app.get('/',(req,res) => {
var config = { url: 'ldap://10.100.1.10',
baseDN: 'dc=HBCAudit,dc=COM',
username: 'traveldesk.dev',
password: '$oftvision#123' }
var ad = new activedirectory(config);
});
//Port Number
const port = 7000;
//CORS Middleware
app.use(cors());
//Start Server
app.listen(port, () =>{
console.log('Server started on port '+ port);
});
But am getting error in command prompt like this:
c:\spitravel>node app.js
module.js:471
throw err;
^

I don't know why am getting this error. Am new to NODEJS.

Its due to depencies of ldapjs module, please run npm install ldapjs and recheck

NodeJS: Error: Cannot find module '/models/filename' after having renamed it

I am still relatively new to NodeJS. Now I encounter this problem: I had a file called "./models/route" I renamed it by changing the filename in VS Code to: "./models/routes". I then changed that name in all of the scripts. I checked, doubledchecked, triplechecked and quadruplechecked that it has been changed everywhere and it has.
Now I get this error in the console:
internal/modules/cjs/loader.js:638
throw err;

[nodemon] app crashed - waiting for file changes before starting..
The error apparently is encountered in internal/modules/cjs/loader.js:638. So it does not point me to a script that I made or can change.
I really am at a loss...
Edit:
As Mosifa points out in his comment the error points to ./wandelverhalen/controllers/routesController.js and ./wandelverhalen/index.js.
Here are the scripts. I still can't find the problem.
index.js:
"use strict";
const express = require("express");
const mongoose = require("mongoose");
const app = express();
const Routes = require("./models/routes");
const homeController = require("./controllers/homeController");
// const errorController = require("./controllers/errorController");
const routesController = require("./controllers/routesController");
mongoose.connect("mongodb://localhost:27017/db_wandelen", {
useNewUrlParser: true
});
const db = mongoose.connection;
db.once("open", () => {
console.log("Connected to MongoDB");
});
app
.set("port", process.env.PORT || 3000)
.set("view engine", "ejs")

.use(express.json())

.use(layouts)
.use((req, res, next) => {
console.log(`Request made to ${req.url}`);
next();
})
// .use(errorController.pageNotFoundError)

.get("/", homeController.start)
.get("/kempen", homeController.kempen)
.get("/rivieren", homeController.rivieren)
.get("/oost_belgie", homeController.oost_belgie)
.listen(app.get("port"), () => {
console.log(`Server running at port ${app.get("port")}`);
});
routesController.js:
"use strict";
const mongoose = require("mongoose");
const Routes = require("./models/routes");
exports.getAllRoutes = (req, res, next) => {
Routes.find({}, (error, routes) => {
if (error) next(error);
req.data = routes;
next();
});
};

How to fix SyntaxError: Unexpected token ... while using socket.io in my local machine

I am trying to use socket.io on one of a simple project but when I run the same on my local machine I am getting this bug. I am not able to figure out what is going wrong my index.js is as follows
const app = require("express")();
const http = require("http").Server(app);
const io = require("socket.io")(http);
const port = process.env.PORT || 8080;
app.get("/", function(req, res) {
res.render("index.ejs");
});
http.listen(port, function() {
console.log("Listening on *:" + port);
});
The full log is here

My node version is 8.0
This looks like it's probably the object spread operator. If you showed the actual line of code that causes the error, we could see for sure.
You will need at least node v8.6 to get support for the object spread operator by default. Starting with node v8.21, it could be enabled via command line flags.

Async/Await not running in Azure App Service

Within my Azure App Service Node.js backend I cannot seem to get the Javascript async/await feature to run. I have changed the default version of Node.js within application settings and package.json to above 7.6. (Changed to 8.9.0)
I would like to use this feature within a custom Express router shown here:
var express = require('express'),
bodyParser = require('body-parser');
var router = express.Router();
router.get('/', function (req, res, next) {
res.status(200).send('GET: This is a test response!');
});
router.post('/:id', async function (req, res, next) {
var context = req.azureMobile;
var newLovedOne = req.body.lovedone;
var newTie = req.body.tie;
console.log('POST: newLovedOne ', newLovedOne);
console.log('POST: newTie ', newTie);
try {
await context.tables('Tie').insert(newTie);
await context.tables('LovedOne').insert(newLovedOne);
} catch (error) {
res.status(500).send('Insert failed!');
}
});
module.exports = router;
Attempting to start the app with the above router produces this:
Application has thrown an uncaught exception and is terminated:

To verify whether the Node.js version is correctly set, you can go to your root and open the iisnode.yml file. Make sure it has the following line with the correct version:
nodeProcessCommandLine: "D:\Program Files (x86)\nodejs\8.9.0\node.exe"

Nodejs not able to run when i move the routes and model to different folders

app.use(bodyParser.json());

/app4/routes/catRoute.js
var _= require('lodash');
var Cat= require('../models/catModel');
module.exports = function(app) {
/*Create*/
app.post('/cat', function(req, res){
var newCat = new Cat(req.body);
newCat.save(function(err){
if(err){ res.json({info: "error during creating of cat create", error:err}); };
res.json({info: 'Cat created successfully'});
});
});
}
/app4/models/catModel.js
var mongoose = require('mongoose');
var catSchema = mongoose.Schema({ name: String, age: Number, type: String });
module.exports = mongoose.model('Cat', catSchema);
Something doesn't look right with the relative path loading.
Given that /app4/routes/catRoute.js is being loaded correctly with a path of ../routes/catRoute, I suspect that doing the following will help:
var Cat = require('../../models/catModel');
This error comes when path is not right for server
Try this
var Cat = require(process.cwd() + '/models/catModel');
Its resolved, the issue is with my catModel.js file has an additional extension, once I updated its working as expected. Thanks for all your help.

Twitter API request error while using node.js

I am trying to make a request to the Twitter API and respond with the JSON.
This is my code.
var http = require('http');
var request = require('request');
var url = require('url');
app.get('/twwets/:username', function(req, response) {
var username = req.params.username;
options = {
protocol: "http:",
host: 'api.twitter.com',
pathname: '/1/statuses/user_timeline.json',
query: { screen_name: username, count: 10}
}
var twitterUrl = url.format(options);
request(twitterUrl).pipe(response);
}).listen(8080);
And this is what I get when I run node app.js in my terminal:
module.js:340
throw err;
^

I need to know what do I do wrong.
[My code may seem useless, but it's just for educational purposes. Please excuse any mistake.]
EDIT: I still get the same error after I saved and run the code in my shell.
Typo;
var request = require('require');
should most likely be
var request = require('request');
EDIT: You're also missing express, I suspect you'll want to add these lines;
var express = require('express');
var app = express();
...and npm install request express to get the modules installed.
