Поставете горния db код в съответните файлове в папка db или както искате да го наименувате и след това можете да използвате вашата заявка

var db =изисквам('./db');

db.order.find({
            where: { id: 0 },
            include: [ db.customer, db.user ]
        })
        .then(function(order){
            console.log(order)
        })
