Nodejs Mysql delete query

to create the MySQL delete query in Nodejs, I have defined 2 steps.
Suppose, You have users table which has 4 records.

Now you want to delete user which has user id is 1

Step:1) firstly create the connection.js file.

const mysql = require('mysql');
const config  = {
  connectionLimit : 10,
  host     : 'localhost', // Database hostname, 
  user     : 'root', // Database Username
  password : 'jnnn23nn', // Database Password,
  database : 'dbname', //Database Name
};

const pool = mysql.createPool(config);
// Export the pool
module.exports = pool;

IN the connection.js file, You have to include mysql package and create the connection pool.

Step:2) Now, create the delete.js file and include the connection.js file and write the delete query in this.

const pool  = require('./connection');

pool.getConnection(function(err, connection) {
  if (err) {
    console.error('error in db connection');
    return;
  }
  console.log('db is connected');
  return ;
}); 

pool.query('delete from users where id=?',[1], function (error, results) {
if (error) throw error;
console.log('result is: ', results);
});

Now, run the delete.js file.

node delete.js

Now, get the users records from the table.

Select * from users
