Published 2022-12-03

This tutorial explains to you how to create a MySql database (schema) from a Node.js application. This article provides you with an example as well.

Using Node.js you can connect to a database and run different operation as creating a table, select data from tables, update rows in tables, insert data into tables or delete information from a database.

In order to make possible this thing, you have to install into Node.js the proper package.

For MySql database you have to install mysql module (package):

npm install mysql

After that you can connect to MySql Database and perform different operations.

Here it is a Node.js code which create a database (schema) in MySQL:

console.log("Application starts ...");
var mysql = require('mysql');
var con = mysql.createConnection({
  host: "localhost",
  user: "root",
  password: "1234",
  database: "world"
var databaseName = "myDatabase";
con.connect(function(err) {
  console.log("[create database in MySql] - block BEGIN ");  
  if (err) throw err;
  varId = 6;
  con.query("create database "+databaseName, function (err, result, fields) {
    if (err) throw err;
   // console.log(result);
  console.log("[create database in MySql] - block END");
console.log("END of the application.");

When you run the code you will se the following into the console (you can see an ASYNC execution):

You can verify into MySQL Workbench to see if the new schema (database) is created:

Now, you can create tables in that schema.
