Why is mysql connection not working with dotenv variables - sql

Question

Good evening,
I have been trying to connect to my database by using dotenv variables.
It worked perfectly before i used it.
I have 2files: 1 file mysqlConfig, where i put my settings for my database, and .env where i put my variables.
I don't see what i am doing wrong here:
SOCKET_PATH='/Applications/MAMP/tmp/mysql/mysql.sock'
USER='root'
PASSWORD='root'
HOST='localhost'
DATABASE='Groupomania'
MysqlConfig :
require('dotenv').config();
var mysql = require('mysql');
// Connexion à MYSQL
var bdd = mysql.createConnection({
socketPath : process.env.SOCKET_PATH,
user : process.env.USER,
password : process.env.PASSWORD,
host : process.env.HOST,
database : process.env.DATABASE
});
module.exports = bdd;
Thank you for your help
Have a nice evening

Answer 1

It might be because the dotenv package hasn't been able to find your .env file.
try printing any of the variables, and see if it's undefined. If it is, my assumption is correct.
console.log(process.env['SOCKET_PATH'])
In that case, you need to manually specify the relative path to your .env file. That can be done by passing an options object to your config function, containing the property path:
const path = require('path')
require('dotenv').config({
path: path.resolve(__dirname, '../../.env')
})

Ok, i just found the issue...
I used console log for every varibales, util i figured out that my USER was not the correct one... it was my last name (i don't know why ?)
I did not know the variable USER is kind of reserved ?
Anyway, this way it works...
SOCKET_PATH='/Applications/MAMP/tmp/mysql/mysql.sock'
USERDB='root'
PASSWORD='root'
HOST='127.0.0.1'
DATABASE='Groupomania'
mysqlConfig
require('dotenv').config();
var mysql = require('mysql');
// Connexion à MYSQL
var bdd = mysql.createConnection({
socketPath : process.env.SOCKET_PATH,
user : process.env.USERDB,
password : process.env.PASSWORD,
host : process.env.HOST,
database : process.env.DATABASE
});
module.exports = bdd;
Your answer helped a lot, thanks !!
