Database queries

[n1c0z]

Personally, I prefer to keep each database query in its own function, i.e. const getUser or updateItem or checkUserExists:

const getUse = (username, cb) => {
  dbConnection.query(
    'SELECT * FROM users WHERE username = $1',
    [username],
    (err, res) => {
      if (err) {
        cb(err);
        console.log(err);
      } else {
        cb(null, res.rows);
      }
    }
  );
};

It makes it easier to read and can also assist with better error handling
