I have installed mysql with using npm then created a connection file :
var express = require("express");
var mysql = require('mysql');
var connection = mysql.createConnection({
host : '127.0.0.1',
user : 'root',
password : '',
database : 'address_book',
});
var app = express();
connection.connect(function(err){
if(!err) {
console.log("Database is connected ... nn");
} else {
console.log(err);
};
When i connect using node connection.js I get this error :
{ Error: connect ECONNREFUSED 127.0.0.1:3306

I was building a simple rest API with node and mysql. But while creating the connection to the database I am getting this error.

I am new to web development and I have started working on Nodejs.
I am trying to connect to the MySQL Server on port 3308, WampServer but instead I always get connected to localhost server.
To ensure that I am using right ports and hostnames, I have tried to setup the connection using MYSQL Workbench and it worked!
But still, I am not able to figure out how to connect with mysql driver.
const sql = require('mysql');
var con = sql.createConnection({
host: '127.0.0.1:3308',
user: 'root',
password: '',
port: 3308
});
con.connect(function (err) {
if (err) throw err;
console.log("Connected!");
});
createDatabaseQuery= theQ =>{
return "CREATE DATABASE ".concat(theQ);
}
con.query(createDatabaseQuery('nodedb'), function(err) {
if (err) {
throw err;
}
});
Here is my output:

Good mornig to you guys. I want to establish a connection to a remote mysql database using node js. but i am facing this error. I do not know if I wrongly specifies the access path to the db
code
var mysql = require('mysql');
var pool = mysql.createPool({
host: "http://kamerun-it.com/mysql",
connectionLimit : 100,
database: "****",
user: "****",
password: "*****",
multipleStatements: true
});
error
throw err;

You probably have an error in your config with the host URL.
Here's a working example with a connection to a remote MySQL:
const mysql = require("mysql");
const connection = mysql.createPool({
host: "remotemysql.com",
user: "aKlLAqAfXH",
password: "PZKuFVGRQD",
database: "aKlLAqAfXH"
});
connection.query(
"SELECT hexcode FROM colours WHERE precedence = 2",
(err, result) => {
err ? console.log(err) : console.log(result[0].hexcode);
}
);
and here's one with mistaken host parameter:
const mysql = require("mysql");
const connection = mysql.createPool({
host: "WRONGremotemysql.com",
user: "aKlLAqAfXH",
password: "PZKuFVGRQD",
database: "aKlLAqAfXH"
});
connection.query(
"SELECT hexcode FROM colours WHERE precedence = 2",
(err, result) => {
err ? console.log(err) : console.log(result[0].hexcode);
}
);
The second one returns the same ENOTFOUND error.
Check if that's the correct URL, if the database can be accessed remotely and via which port you can use it.
I tried connecting to my first MySql server with the following code
var mysql = require('mysql');
var con = mysql.createConnection({
host: "localhost",
user: "yourusername",
password: "yourpassword"
});
con.connect(function(err) {
if (err) throw err;
console.log("Connected!");
});
But I get the following error. It only works if I comment out the "throw err" part
C:\NodeJS Projects>node demo_db_connection.js

if (err) throw err;
