How does mysql.createConnection work?

mysql.createConnection() is a method provided by the Node.js MySQL module that creates a new connection to a MySQL server with the given connection options. It returns a new Connection object that can be used to perform various operations on the database, such as executing queries and managing transactions. When the connection is no longer needed, it should be closed using the connection.end() method.

const mysql = require("mysql");

const connection = mysql.createConnection({
  host: "localhost",
  user: "root",
  password: "password",
  database: "mydatabase",
});

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

  console.log("Connected to database as ID", connection.threadId);
});

This code creates a connection to a MySQL database running on localhost, using the username root and password password. It then prints the ID of the connection if the connection was successful. Note that you should replace mydatabase with the name of the database you want to connect to.
