Building a Realtime Trello Board with Supabase and Angular

In this tutorial, we built a real-world Angular application using Supabase as our backend service. We created an app that closely resembles Trello, allowing users to create boards, lists, and cards in real time. The main features of the app include: 1. Creating and managing boards with titles and deletion functionality. 2. Adding, updating, and deleting lists within a board. 3. Adding, updating, and deleting cards within a list. 4. Inviting users to collaborate on a board by entering their email addresses. 5. Real-time updates for all changes made to the app's data. To achieve this, we utilized Supabase's real-time features, which allowed us to listen for changes in our database tables and update the application's state accordingly. We also implemented various forms of input validation and error handling throughout the project. The final code for this tutorial can be found on Github, where you can easily set up your own Supabase instance and create the necessary tables using the provided SQL file. This app serves as a great starting point for building more complex applications with Angular and Supabase in the future.
