(backend webdevelopment) Git-bash terminal and localhost just hangs when connecting database - mysql

Question

Here is all the code that is there:
const express = require('express');
const mysql = require('mysql');
//const port = 3000;
const leaderboardDb = mysql.createConnection({
//host : 'localhost',
host: '127.0.0.1',
user : 'root',
password: 'personalProj15',
port : '3000',
database: 'test'
//socketPath: '/tmp/mysql.sock'
})
leaderboardDb.connect((err) => {
if(err) {
console.log(err);
}
else {
console.log('MySQL connected');
}
})
const app = express();
app.listen('3000', () => {
console.log('Server started (on 3000)');
})
app.get('/createDb', (request, response) => {
let sql = 'CREATE DATABASE leaderboardDatabase';
leaderboardDb.query(sql, (err, result) => {
if(err) { throw err}
else {
console.log(result);
response.send("Testing...");
}
})
})
"Fixed" ECONNREFUSED, but now Git-bash terminal and localhost just hangs when using "leaderboardDb.connect((err)". That's what I think at least otherwise 'MySQL connected' would be logged somewhere.
Notes:
The error is being thrown from leaderboardDb.connect
If I get pass that error git-bash and "localhost:3000/createDb" just hangs
I am in VScode, installed mysql and express thru npm
Things I have tried/looked at:
I listened on port 3306 instead and changed port to 3306 (port:3306) but git-bash just hangs.
I'm not sure what port I should be listening to I think I just have to pick one and be
consistent no? (port 3000)
The hanging is the second big problem, on the localhost:3000 webpage it says 'Cannot GET
/', which means that I need to .connect, right? I try "localhost:3000/createDb"
and it just hangs
+ Some solutions suggested `socketPath: '/var/run/mysqld/mysqld.sock'` and a different path that involved `/tmp/mysql.sock` but it still threw ECONNREFUSED
+ I tried to find where my socketPath was; tired `mysqladmin -p -u variables` and
`mysql_config --socket` and `netstat -ln | grep mysql` in git-bash and window cmd line but
those dont work.
+ Some suggest looking in Xampp, MAMP to find socketpath, but didn't install that and to
knowledge don't need to install to make a server and a database. Can't I just find the
socket path in windows cmd line/git-bash?
Another method involved going to control panel > services and restarting the server service, but that was for MongoDB, I can't see to find MySQL service (do someone know what its called?)
Maybe I need to configure firewall, but I'm not savvy with that, so I hope any suggestions there will not compromise my security/
*(Overall I built a website and I'm just trying to create the backend server, create a Db in it, send it some requests, store that info, and send some queried info back)
