Cannot read property 'caseSensitive' of undefined

I created a simple code and I don't know what's going on because code is correct as far as I know. But it's still giving me this case sensitive error.
App.js
const express = require('express');
const path = require('path');
const data = require('./routes/data.js');
const bodyparser = require('body-parser');
const app=express();
app.use(bodyparser.urlencoded({extended:false}));
app.use(data.route);
app.use((req,res,next)=>{
res.sendFile(path.join(__dirname, '/views/home.html'));
});
app.listen(3000)
Data.js
const express = require('express');
const path = require('path');
const router = express.Router();
router.get('/add-product', (req,res,next)=>{
res.sendFile(path.join(__dirname, '/add-product.html'));
});
module.exports = router;
Error

Just update your app.js file like this:
const express = require('express');
const path = require('path');
const data = require('./routes/data.js');
const bodyparser = require('body-parser');
const app=express();
app.use(bodyparser.urlencoded({extended:false}));
app.use(data);
app.use((req,res,next)=>{
res.sendFile(path.join(__dirname, '/views/home.html'));
});
app.listen(3000)
the mistake was in:
app.use(data.route);
it must be like this:
app.use(data);

getting a type error when calling back data from an array

I tried to get the data from a nested array but ended up getting the error type error cannot read property "value" of undefined, I don't know If I calling back in a wrong way but I end up getting the output in console along with the error
const express = require('express');
const app = express();
var bodyParser = require('body-parser');
app.set("view engine", "ejs");
app.use(bodyParser.urlencoded({ extended: true }));
var entries = [{name:"", address:"", month:"", year:""}];
app.get("/", function(req, res){
res.render("homepage");
});
app.get("/addentry", function(req, res){
res.render("add");
});
app.post("/add", function(req, res){
var input = req.body;
var newEntry = {name: input.name, address: input.address, month: input.month, year: input.year};
entries.push(newEntry);
res.redirect("/addentry");
});
app.post("/search", function(req, res){
var search = req.body;
for(var i = 0; i <= entries.length; i++){
console.log(entries[i].name);
}
res.redirect("/addentry");
});
app.listen(3000, function(){
console.log("Server Started Successfully");
});
I end up getting this error always

You need to add app.use(bodyParser.json()); after this line => app.use(bodyParser.urlencoded({ extended: true }));

connecting Neo4j to nodejs error

I am trying to set up neo4j databace to use with javescript code.
When I run my code, I keep getting this

var express = require("express");
var path = require("path");
var logger = require("morgan");
// var cookieParser = require("cookie-parser");
var bodyParser = require("body-parser");
var neo4j = require("neo4j-driver").v1;
var app = express();
//
// <script src="lib/browser/neo4j-web.min.js"></script>
//view engine setup
app.set("views", path.join(__dirname, "views"));
app.set("view engine", "ejs");
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extened: false}));
// app.use(cookieParser());
app.use(express.static(path.join(__dirname, "public")));
var driver = neo4j.driver("bolt://locthost", neo4j.auth.basic("neo4j", "test"));
var session = driver.session();
//home route
app.get('/', function(req, res){
session
.run("MATCH (n) RETURN n")
.then(function(result){
result.records.forEach(function(records){
console.log(records._fields[0]);
});
})
.catch(function(error){
console.log(error);
});
res.render("index");
});
app.listen(3000);
console.log('Server has started');
module.export = app;
What do I need to do?

You may have a typo in your bolt URI.
If your code is running on the same machine as the neo4j server, try changing locthost to localhost.

Getting error while posting the data using Node.js

I am getting the following error while posting the data via REST API through Postman using Node.js. I am providing my code below.
server.js:
var express=require('express');
var morgan = require('morgan');
var http=require('http');
var bodyParser= require('body-parser');
var methodOverride = require('method-override');
var mongo = require('mongojs');
var app=express();
var server=http.Server(app);
var port=8080;
require('./route/route.js')(app);
app.use(express.static(__dirname + '/public')); // set the static files location /public/img will be /img for users
app.use(morgan('dev')); // log every request to the console
app.use(bodyParser.urlencoded({ extended: false,limit: '5mb' })) // parse application/x-www-form-urlencoded
app.use(bodyParser.json({limit: '5mb'})) // parse application/json
app.use(methodOverride()); // simulate DELETE and PUT
app.get('/',function(req,res){
res.json({"message": "Task management application."});
})
server.listen(port);
console.log("Server is running on the port"+port);
route/route.js:
var task=require('../controller/controller.js');
module.exports = function(app) {
app.post('/signup',task.userSignup);
}
controller/controller.js:
var mongoJs=require('mongojs');
var database='TASK';
var collections=['f_users'];
var db=mongoJs("127.0.0.1:27017/"+database, collections);

if (!err) {
if (docs) {
res.json({'message':'User has registered successfully'});
}
}
})
}
I am doing the post like below.
Here I am getting the following error while posting the data.

How can I resolve this error and save the data successfully?

Using session in EJS with node

I am new to node and need some help in using session. I am using EJS to render my web-pages. Please find my code below.
app.js
var express = require('express');
var registerController = require('./controllers/registerController');
var app =express();
var bodyParser = require('body-parser');
var sessions=require('express-session');
app.set('view engine', 'ejs');
app.use(express.static('./public'));
app.use(sessions({
secret:'asasds*(&^*(',
resave:false,
saveUninitialized:true
}));
app.use(function(req, res, next) {
res.locals.user = req.session.user;
next();
});
//controllers
registerController(app);
app.listen(3000);
console.log( " you are listening to port 3000");
registercontroller.js
var bodyParser = require('body-parser');
var fs = require('fs');
var urlencodedParser = bodyParser.urlencoded({ extended: false });
module.exports=function(app){
app.get('/register',function(req,res){
res.render('register');
});
app.post('/register',urlencodedParser,function(req,res){
console.log(" inside controller :::" );
var userObj = {
"username":req.body.username,
"password":req.body.password,
"email":req.body.email,
"fNmame":req.body.fNmame,
"lNmame":req.body.lNmame
}
console.log(" userObj :::" + JSON.stringify(userObj));
fs.writeFile("/assets/data.txt", JSON.stringify(userObj), function(err) {
if(err) {
return console.log(err);
}
console.log("The file was saved!");
});
var val = req.session.user;
res.render('index2',{session: req.session});
});
};
index2.ejs
<%= JSON.stringify(session) %>
Using all the above I get the below error
<%= JSON.stringify(session) %>

you need to include this basically
