Literally all of my functions look like this!

validate_token_credentials.js

const validateTokenCredentials = (connection) => (fields) => new Promise( (resolve, reject) => {
	const validateQuery = 'SELECT COUNT(*) AS total FROM sessions WHERE sessions.accountId = ? AND sessions.token = ?;';
	return connection.query(validateQuery, [fields.id, fields.token])
		.then(results => results[0].total > 0 ? resolve(fields) : reject({msg: 'Invalid password change credentials', extra: [fields.id, fields.token]}))
	;
});
