Can't get it to work with MySQL

[Ralle]

This is my code:

var mysql = require("db-mysql");

  self.db = new mysql.Database({
    "hostname": "localhost",
    "user": "root",
    "password": "root",
    "database": "my"
  });

  self.db.on('error', console.log);
  self.db.on('ready', console.log);
  self.db.connect();```

Here is the compile log
```code

And here is the error I get:

              ^
