I'm using a vServer from Ionos for a little project. I installed a MariaDB and NodeJS. Currently I'm trying to connect them both. Here is my code:
const mariadb = require('mariadb');
const pool = mariadb.createPool({
host: 'localhost',
user:'root',
password: 'xxxxxxxxx',
database: 'christmastrees',
connectionLimit: 5,
});
async function asyncFunction() {
let conn;
try {
conn = await pool.getConnection();
const rows = await conn.query("SELECT * from bäume");
console.log(rows); //[ {val: 1}, meta: ... ]
} catch (err) {
throw err;
} finally {
if (conn) return conn.end();
}
}
But when executing the file (node app), I get an error message after a few seconds
Error: connect ECONNREFUSED 127.0.0.1:3306
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1157:16)
From event:

fatal: true
}
So I searched for help and after 2 hours I literally found only one Idea. I added this line of code to my connection...
port: '/var/run/mysqld/mysqld.sock'
I tryed again to use node app, but this time I didn't get an error message, it is loading forever and nothing happens.
I would be so grateful for any help...
So I found the solution to my problem.
I checked if my MariaDB Service is even running and no it wasn't ^^

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:

throw er; // Unhandled 'error' event

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 anyone tell me why I am not able to connect to the database?
run MySql installer
reconfigure the MySql Server. it will work fine.

Check port of mysql you are using, maybe 3307 ?
So I'm new to node.js and I'm trying to make a connection to my local database to later insert data.
However when I execute my code it gives me a connection error with errorcode ESOCKET. I tried different ways to structure my connectionstring but it always gives me this error.
As I said I'm new to nodejs so I'm not really sure if the problem is my connection string or the port it uses (1433) or something entirely different.
code:
const sql = require('mssql');
const config = {
user: 'test',
password: 'test',
server: '.',
database: 'Parkings'
}
async function databaseconn(parking){
try{
let pool = await sql.connect(config);
await pool.request().query(`
if not exists (select 1 from [Parking] where [Name] = '${parking.name}')
begin
insert into Parking ([Name], [Type], [Latitude], [Longtitude], [MaxCap])
values ('${parking._name}', '${parking._type}', ${parking._latitude}, ${parking._longitude}, ${parking._maxcap})
end
`);
await pool.request().query(`
insert into [Entry] ([TimeDay], [Available], [ParkingId])
values (${p._time}, ${p._available}, (select Id from Parking where Name = '${p._name}'))
`);
pool.close();
} catch (err){
console.log(err);
}

SOLUTION
after a lot of trouble I fount the sollution to the issue thanks to a github post. You have to enable the TCP/IP protocol on your sql server and restart it. Guide in links below:
https://github.com/tediousjs/tedious/issues/799
https://www.blackbaud.com/files/support/infinityinstaller/content/installermaster/tkenablenamedpipesandtcpipconnections.htm
Each time I try to connect to my server to access the documents in the database, it comes back with a connect ETIMEDOUT error.
I own the server, running Mongo 4.0, have run mongod and left running, there is data in the collection.
let MongoClient = require('mongodb').MongoClient;
let uri = "mongodb://notmyrealusername:notmyrealpassword#thomas.misson.info/tom-portfolio";
MongoClient.connect(uri, { useNewUrlParser: true }, async function(err, db) {
try{
if (err) throw err;
let res = await db.collection("projects").find().count()
console.log(res);
db.close();
}
catch(err)
{
console.log(err);
}
});
Error message:

I have opened the port using netsh advfirewall firewall add rule name="Open mongod port 27017" dir=in action=allow protocol=TCP localport=27017
Have now added new interface to the mongod.cfg file.

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: '',
};
