This should be really basic and simple to do but I can seriously not find any understandable information on how to create a simple database for my nodejs typescript project.
I have installed the following packages with npm:
I have attempted the following commands at the terminal
C:\repos\NodeNew>mysql2 -u root -p
'mysql2' is not recognized as an internal or external command,
operable program or batch file.
C:\repos\NodeNew>mysql -u root -p
'mysql' is not recognized as an internal or external command,
operable program or batch file.
C:\repos\NodeNew>node mysql2 -u root -p
module.js:538
throw err;
^
Error: Cannot find module 'C:\repos\NodeNew\mysql2'
at Function.Module._resolveFilename (module.js:536:15)

C:\repos\NodeNew>
So how do I CREATE my database so I can connect to it with sequelize etc?
The tools you have installed are only for connecting a Node.js app to MySQL and do not include command-line tools to manage the MySQL server.
I will assume you have installed MySQL and it's running – you should then be able to find its mysql.exe
command line client in the bin/
directory in the server's installation directory. If you haven't fiddled with authentication, just running it might work.
When you get to a MySQL prompt, you can follow any old instructions for creating a database; CREATE DATABASE foo;
is the gist of it (authentication and permissions being a different story).
Since you're on Windows, you might want to look into HeidiSQL – it's been a while since I've used it, but it's a decent graphical MySQL management tool.
You can also use mysql2
to create the database – illustrated below – but I recommend getting a management tool.
const mysql = require('mysql2');
const connection = mysql.createConnection({
host: 'localhost',
user: 'root',
database: 'mysql',
});
connection.query('CREATE DATABASE foo');
You should have MySQL installed on your computer, to install mysql on Windows see the following page: MySql Once you have MySQL up and running on your computer. Open the Command Terminal and execute the following:
npm install mysql
Now you have downloaded and installed a mysql database driver. Node.js can use this module to manipulate the MySQL database:
var mysql = require('mysql');
To create a conecction create a file connection.js:
var con = mysql.createConnection({
host: "localhost",
user: "yourusername",
password: "yourpassword"
});
con.connect(function(err) {
if (err) throw err;
console.log("Connected!");
});
to test it save the file and run:
node connection.js
Which will give you this result:
Connected!
