Bit.io randomly terminating connecting with node.js

Bit.io randomly terminates connecting with node.js.
When I try to run the following code my node.js works fine for a few minutes but then randomly crashes and gives the error listed at the bottom of this page. I have tried to fix this but I am stuck. Don't know if it's a problem with bit.io or with me. Thanks!!
Code:
const { Client } = require('pg');
const client = new Client({
user: 'process.env.USER',
host: 'db.bit.io',
database: 'process.env.DATABASE',
password: 'process.env.PASSWORD',
port: 5432,
ssl: true,
});
client.connect();
client.query('SELECT * FROM "HPI_AT_state" limit 10;', (err, res) => {
console.table(res.rows);
})
Error:
node:events:491
throw er; // Unhandled 'error' event
^
Error: Connection terminated unexpectedly

I have figured out the problem. It seems that the issue was because Bit.io terminates the connection if unused for 60 seconds. It was fixed by using Client instead of Pool.
const { Pool } = require('pg');
const pool = new Pool({
user: process.env.USER,
host: 'db.bit.io',
database: process.env.DATABASE,
password: process.env.PASSWORD,
port: 5432,
ssl: true,
});
pool.query('SELECT * FROM "SaveData" limit 10;', (err, res) => {
console.table(res.rows);
});

Can't use and connect to MongoDB

So, I am building a small URL shortener project with js, express, and MongoDB but, I got errors when I'm trying to run my local server and I can't connect to MongoDB!
This is my code:
const express = require('express')
const mongoose = require('mongoose')
const ShortUrl = require('./models/shortUrl')
const app = express();
mongoose.connect('mongodb://localhost/urlShortener', {
useNewUrlParser: true, useUnifiedTopology: true
})
app.set('view engine', 'ejs')
app.use(express.urlencoded({ extended: false}))
app.get('/', async (req, res) => {
const shortUrls = await ShortUrl.find()
res.render('index', { shortUrls: shortUrls })
});
app.post('/shortUrls', async (req, res) => {
await ShortUrl.create({ full: req.body.fullUrl })
res.redirect('/')
})
app.get('/:shortUrl', async (req, res) => {
const shortUrl = await ShortUrl.findOne({ short: req.params.shortUrl })
if (shortUrl == null) return res.sendStatus(404)
shortUrl.clicks++
shortUrl.save()
res.redirect(shortUrl.full)
})
app.listen(process.env.PORT || 5000);

Node.js v17.7.2
[nodemon] app crashed - waiting for file changes before starting...
Thank u guys =)
I was trying to start the small URL-shortener project that I wrote in js, express, and MongoDB but, the problem is that I can't connect to my MongoDB database :(

I solved the problem, so, I replaced localhost with 127.0.0.1 in the connection string and now my problem is solved!
it is because of some ipv6 configurations...
Thank u :)

Connect ssh server through nodejs code with ssh key and server name

I have vpn access, so i can ssh to server by following command from terminal
ssh qa-trinath01.my-qa
Its working fine from terminal.
But from nodejs, its not working. my code is
var express = require("express");
var app = express();
var node_ssh = require('node-ssh')
var
ssh = new node_ssh()
ssh.connect({
host: 'qa-trinath01.my-qa',
username: 'tanantham',
port: 27017,
privateKey: '/Users/tanantham/.ssh/id_rsa'
}).then(function() {
console.error('Success: ');
}).catch((error) => {
console.error('ERROR: ', error);
});;
app.listen(3001);
I am getting output as
ERROR: { Error: getaddrinfo ENOTFOUND qa-trinath01.my-qa qa-trinath01.my-qa:27017
at errnoException (dns.js:50:10)
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:92:26)

syscall: 'getaddrinfo',
hostname: 'qa-trinath01.my-qa',
host: 'qa-trinath01.my-qa',
port: 27017,
level: 'client-socket' }
Can some one suggest the nodejs code to connect to ssh, i have only ssh key and ssh server name details.
ssh key -> /Users/tanantham/.ssh/id_rsa
server name -> qa-trinath01.my-qa

Have you tried to replace 'privateKey' with 'password' and enter your password.
It's probably not the most secure but it normally works.
Unless you have to use your private key from id-rsa
ssh = new node_ssh()
ssh.connect({
host: 'qa-trinath01.my-qa',
username: 'tanantham',
port: 27017,
password: 'YourPasswordHere'
}).then(function() {
console.error('Success: ');
}).catch((error) => {
console.error('ERROR: ', error);
});;
app.listen(3001);

Trouble making nodejs mysql connection

I am trying to make a simple connection between my nodejs server and my mysql db (using Microsoft SQL server manager studio v14), below is my code and the error message appearing in my console window.
here is my code:
var express = require('express');
var app = express();
var sql = require("mssql");
app.get('/', function (req, res) {
// config for your database
var config = {
user: 'superadmin',
password: '***',
server: 'localhost',
database: 'XXX'
};
// connect to your database
sql.connect(config, function (err) {
if (err) console.log(err);
// create Request object
var request = new sql.Request();
// query to the database and get the records
request.query('select * from Schools', function (err, recordset) {
if (err) console.log(err)
// send records as a response
res.send(recordset);
});
});
});
var server = app.listen(5000, function () {
console.log('Server is running..');
});
The error I am getting looks like this:
Server is running..

I am rather new at this particularly with dealing with databases. Can someone explain what the error means?

Add this line to the config:
options: {
encrypt: false
}
It will finally look like:
var config = {
user: 'superadmin',
password: '***',
server: 'localhost',
database: 'XXX' ,
options: {
encrypt: false
}
};

try to put encrypt: false in your config{}, it will work.

your error:
ConnectionError: Failed to connect to localhost:1433 - Could not
connect (sequence)
My problem was resolved by adding port
var config = {
user: 'superadmin',
password: '***',
server: 'localhost',
database: 'XXX',
port: '',
};

What's wrong with the following Server.JS file? We are trying to connect Deployd to Heroku and keep getting the following error. We're using Nitrous, and I have configure the mongoDB port to 5000. Any help is appreciated. Thanks a ton!
Server.JS
// require deployd
var deployd = require('deployd');
// configure database etc.
var server = deployd({
port: process.env.PORT || 5000,

host: '0.0.0.0',
port: 5000,
name: 'database_name',
credentials: {
username: 'username',
password: 'password'
}
}
});
// heroku requires these settings for sockets to work
server.sockets.server.set('transports', ["xhr-polling"]);
// start the server
server.listen();
// debug
server.on('listening', function() {
console.log("Server is listening on port: " + process.env.PORT);
});
// Deployd requires this
server.on('error', function(err) {
console.error(err);
process.nextTick(function() { // Give the server a chance to return an error
process.exit();
});
});

You are using same port for two servers.
You can kill one of them with that command
netstat -ano|findstr "PID :5000"
5000 is your port.
