The tutorial aims to create a web application that allows students to reserve office hour time slots with their professors, using Node.js, Express, SQLite, and the Vonage Messages API. The application will have three HTML templates: an input form for student information, an error page for handling invalid data, and a confirmation page for successful reservations. The backend will be implemented using Express and SQLite to store reservation requests in a database. When a reservation is successfully processed, a text message will be sent to the student's phone number using Vonage's Messaging API.
