I am trying to create a simple node server and call it. Here is what I am doing:
var net = require('net');
const https = require('https');
var srv = net.createServer(function(sock) {
sock.end('Hello world\n');
});
srv.listen(0, function() {
console.log('Listening on port ' + srv.address().port);
https.get('https://localhost:' + srv.address().port);
});
Here is the error I am getting:
Listening on port 35147
events.js:167
throw er; // Unhandled 'error' event
^

I am trying to run that code here: https://www.tutorialspoint.com/execute_nodejs_online.php.
How could I make the sock.end or is there an easier way to create a node server listener? I.e. without using the sockets.

I forked a repo I found and running it locally was fine with no errors however I wanted to run it locally on https so I changed the code of src/index.js
const server = createServer();
to
const options = {
key: fs.readFileSync('localhost-key.pem'),
cert: fs.readFileSync('localhost.pem')
};
const server = https.createServer(options, app)
But I started getting the error after the change when I try to access the website on https://localhost:8080

I'm using node.js to create connect to server on EC2.
The client.js is on the physical machine using a function http.get to get to the server.js on EC2, which using the express.get to connect.
When I ran the two file on the EC2 and my physical machine, nothing happened. And I had the error of Error: connect ETIMEDOUT.
Am I using the wrong ip address? What I use is the public Ipv4 ip.
server.js on EC2 with Ipv4 add: 100.27.18.131
const express = require('express');
const app = express();
const port = 3000;
app.get('/', (req, res) => {
calc = 0
for (i=0;i<10000;i++) {
calc += Math.random() * Math.random();
}
console.log(calc);
res.send(calc.toFixed(10));
});
app.listen(port, () => {
console.log(`listening on port ${port}`);
});
client.js on pyhsical machine:
const http = require('http');
setInterval(loadtest, 100); //time is in ms
function loadtest()
{
http.get('http://100.27.18.131:3000', (res) => {
res.on('data', function (chunk) {
console.log('' + chunk);
});
});
}

I have run the server and getting an error as:

mongoose.connect(`mongodb://localhost/${env.db}`);
const db = mongoose.connection;
db.on('error', console.error.bind(console, "Error connecting to MongoDB"));
db.once('open', function(){

});
module.exports = db;
I have tried by installing redis and adding it into script but error is same.And also tried in production and development environment but the error is same.
This issue seems to be with redis server. Try running redis-server in the terminal.
Hope this helps!
I trying to listen on port using express:
const http=require('http');
const PORT_=process.env.PORT||7000;
const express=require('express');
const app=express();
app.use((req,res,next)=>{
res.send("Hellow world"+PORT_);
next();
});
app.listen(PORT_,(err)=>{
err===true ? console.log(err):console.log('run on '+port_);
});
When I run the program on any port, get following error:
node:events:498
throw er; // Unhandled 'error' event
^
Error: listen EACCES: permission denied :::7000

The program works properly while I'm using http module.
You are getting the error because the port you are trying to listen on is already in use. Try to listen on a different Port other than the one you are using in your code.
I've been trying to send http reqeust by http node module by following code
const https = require('https')
http.request('http://newportal.timesgroup.cn/Pages/Home.aspx', () => {
console.log('success')
})
but got the message

throw er; // Unhandled 'error' event

When I switch the code to
const request = require('request')
request.get('http://newportal.timesgroup.cn/Pages/Home.aspx', () => {
console.log('success')
})
it worked and got a response with 200.
Then I try to capture network packages by Fiddler, I found no package was sent when using http.request.
This error only occurs in Windows system inside our working domain network.
maybe try https instead of http since you defined it https
https.request('http://newportal.timesgroup.cn/Pages/Home.aspx', () => {
console.log('success')
})
