MySQL database connection js code package

Js code connecting to the database:
dbase.js

1  // derived tidied mysql module 
2  // query that is passed to the SQL statement, written as a function of the parameters of the callback function 
. 3 the let mSQL = (SQL, the params, the callback) => {
 . 4      const = mysql the require ( 'mysql ' );
 . 5      const = Conn mysql.createConnection ({
 . 6          Host:' localhost ' ,
 . 7          Port: 3306 ,
 . 8          User:' the root ' ,
 . 9          password:' the root ' ,
 10          Database:' Heima '
 . 11      });
 12 is      / / connection mysql server 
13 is      conn.connect ();
 14      //Prior to End, implement the query operation 
15      conn.query (SQL, the params, the callback);
 16      // Close mysql server 
. 17      conn.end ();
 18 is  }
 . 19  // export module (derived when an object or export, or derive function, where function is derived mSQL 
20 is module.exports = mSQL;

Other js file database operations need to be loaded dbase.js modules:

1  // using a lookup table operation mysql 
2 const the require DB = ( 'User ./' );
 . 3 DB ( 'SELECT ID, name, Age from Student', null , (ERR, Result) => {
 . 4      IF (ERR ) {
 . 5          the console.log (ERR);
 . 6      }
 . 7      the console.log (Result);
 . 8 })
