Send SMS Notifications to Your Supabase Users Using Node.js and Twilio

The tutorial guides users in creating a mobile backend using Supabase, a Postgres database-as-a-service. Users are required to set up two tables, profiles and user_data, to store publicly accessible user data such as username, avatar_url, and website, and the user's metadata including their phone number. The tutorial then instructs users on how to connect the new Supabase database to the Twilio SDK and send each user an SMS notification using Node.js. Users must create a new project in Supabase, initialize the tables, add a new user into the database, create a Node.js app to query each user, install the Twilio SDK, and finally execute the app in their command line. The tutorial concludes by suggesting potential next steps for extending this application, including creating a user interface that allows users to register and automatically populate the database, and providing a front end form using Express.js to send custom messages from the browser.
