Intro To Supabase: Setup, Database, Auth, APIs & RLS Explained | Part 1 | Supabase Crash Course
Before writing any frontend code, let’s first understand what Supabase really is and why it has become one of the most powerful tools for modern developers.
In this video, you’ll learn:
What Supabase is and how it compares to Firebase
How to set up your first Supabase project
How to create a database table using the Table Editor
How Supabase automatically generates REST & GraphQL APIs
How Authentication, Storage, and Security (RLS) work
How to enable Row Level Security and add policies
How to access API keys & documentation
How to prepare your backend before connecting it to the frontend
By the end of this video, you’ll understand how Supabase becomes your backend-as-a-service, handling authentication, database, storage, and security — so you can focus on building features, not servers.
In the next video, we will connect this backend to a real frontend using the official Supabase client library.
