//put these lines in a seperate file
const mysql = require('mysql2');

const connection = mysql.createPool({
    host: "localhost",
    user: "",
    password: "",
    database: ""
    // here you can set connection limits and so on
});

module.exports = connection;

//put these on destination page
const connection = require('../util/connection');

async function getAll() {
    const sql = "SELECT * FROM tableName";
    const [rows] = await connection.promise().query(sql);
    return rows;

Connecting to a SQL database using Node.js and the mysql package:

const mysql = require('mysql');

const connection = mysql.createConnection({
  host: 'localhost',
  user: 'username',
  password: 'password',
  database: 'databasename'
});

connection.connect((err) => {
  if (err) {
    console.error('Error connecting to database:', err);
    return;
  }
  console.log('Connected to database');
});
