app.use(express.urlencoded({extended:false})) throws error on submit - node.js

I had to submit a form containing few parameters from localhost:2000/articles/new. I put the form method and action as <form action="/articles" method="POST">.
My post function is in article route and is like this:
router.post("/", (req, res) => {
console.log("sent")
console.log(req)
res.end()
})
My server.js file contains app.use("/articles", articleRouter)
I have used app.use(express.urlencoded({extended:false})) in server.js file
Now problem arises here:
==> when I use the app.use(express.urlencoded({extended:false})) I get error on submitting form.
The error I got is below:

==>But when I don't use it and submit the form the console.log of post function (router.post function ) works. I do not know what is the problem here please help me.

You can use ldapjs, it's very simple and easy to use.
var ldap = require('ldapjs');
var client = ldap.createClient({
url: 'ldap://127.0.0.1:1389'
});
client.bind('cn=root', 'secret', function(err) {
if(err){console.log(err);}
});

ReferenceError: require is not defined (node.js)

I'm trying to run a node.js script from my node.js server. The problem is that the modules I import with require () do not work anymore while all the modules and files are in the same folder.

Thank you in advance,
I had a similar problem - server-side nodejs thinking that require is not defined.
It turns out the line "type": "module" in my package.json was causing this error, and once I removed that require worked as expected.

I'm using webpack with laravel, but i keep getting this error,I dont have any idea where to look for this issue or what could be the problem.
Any tips?
Thanks!
Try deleting the mix-manifest.json file from /public
From https://github.com/JeffreyWay/laravel-mix/issues/772
The Error is from JSON parser. Generally speaking, it is caused by pass wrong parameter to JSON.parse. Double check if you are trying to parse some improper string to JSON. I used to have this error when I passed a normal string to JSON parser.

Type Error: require(...) is not a function in SendGrid NodeJS

I am trying to send emails using the following doc on sendrid:
https://sendgrid.com/docs/Integrate/Code_Examples/v2_Mail/nodejs.html
My app.js looks like this:
var sendgrid = require('sendgrid')('SENDGRID_APIKEY');
When runnig npm start I get the following error:
var sendgrid = require('sendgrid')(conf);

Any ideas what I am doing wrong? conf is a variable where I store my API key.
I am using a clean express installation.
THANKS
My package.json can be looked here as requested:
http://pastebin.com/pGKWFReX
The latest documentation shows a different structure for initialization.
You should try doing
var sg = require('sendgrid').SendGrid(conf);

Code of nodejs using mongoose works on local machine but on VPS it doen't

This works on windows 7 localhost:

How to fix it?
The error was the name is really undefined, due to userDBName is undefined. It relative with 'nconf' and config.json. Just incorrect way to this file.
