ETA Notifications with Node.js and Express

This tutorial demonstrates how to implement an on-demand notification system for a fake laundry service using Node.js and Express. The system allows delivery drivers to trigger notifications when picking up or delivering orders, which are then sent via Twilio's SMS API. The system also handles incoming Twilio callbacks to update the notification status of each order, allowing for automation and business logic to be applied as needed. The tutorial covers key concepts such as routing, middleware, and model methods, providing a comprehensive overview of how to build a scalable and reliable notification system using Node.js and Express.
