How to hide SQL data in node js?

Question

Node.js

I'm learning node js and I'm facing the same problem.
I connected the Mysql database to the app.js file, but the problem is that you can enter this file remotely by simply entering a link to it, for example
test.ru/app.js
any user can log in and view the data.
How to hide them so that the password, login, etc. are not visible. ?
Connection example:

var connection = mysql.createConnection({
 host: 'localhost',
 user: 'root',
 password: '1111111',
 database: 'app',
});

Answer 2

I think it's time to start learning Node.js first.

Answer 3

Write in the .htaccessfile:

<Files "app.js">
Order Allow,Deny
Deny from all
</Files>

But the main question is - why do you need to store this file in a public folder?

Answer 4

It is necessary that only routes that give data via json stick out and that's it
. The code itself should be hidden below the level of the web server.
