What problem does it solve?

Supabase provides a full PostgreSQL database with automatic REST/GraphQL APIs, real-time subscriptions, Row Level Security, and edge functions.

Core Features & Use Cases

Real-time subscriptions: receive live updates from database changes.
Row Level Security (RLS): enforce fine-grained access control on tables.
Edge functions & serverless workflows: run logic close to users and integrate with other services.
JavaScript client integration: use the official supabase-js client to interact with the database from frontend or backend.
Use Case: build a multi-tenant dashboard with secure data access and live charts.

Quick Start

Install the Supabase JavaScript client and initialize it with your project URL and anon/public key to start querying and subscribing to real-time changes.

FAQPage Schema

How do I implement Row Level Security in PostgreSQL for a multi-tenant web app?▼

Row Level Security (RLS) in PostgreSQL enforces fine-grained access control on database tables. You configure RLS policies directly in your Supabase project to secure data access for multi-tenant applications, ensuring users only see their own data.

How do I set up real-time subscriptions to database changes in a JavaScript application?▼

Real-time subscriptions let your JavaScript application receive live updates from database changes. You initialize the official supabase-js client with your project URL and anon key, then subscribe to database events to push live updates to your frontend.

Can I use Supabase edge functions with the supabase-js client for serverless workflows?▼

Yes, edge functions run serverless workflows close to your users and integrate with other services. You use the supabase-js client alongside edge functions to handle logic and interact securely with your PostgreSQL database.

What do I need to configure before connecting my JavaScript frontend to a Supabase database?▼

You need a configured Supabase project, the @supabase/supabase-js client installed, and proper environment configuration. Specifically, you must set your project URL and anon key to initialize the connection and start querying data.

Does Supabase provide automatic REST and GraphQL APIs for PostgreSQL databases?▼

Supabase provides a full PostgreSQL database with automatic REST and GraphQL APIs. This means you get instant, ready-to-use endpoints for your data without writing custom backend server code to expose your tables.

When should I use Supabase real-time subscriptions instead of manual polling for live updates?▼

Supabase real-time subscriptions are ideal for applications requiring live updates, such as a multi-tenant dashboard with live charts. Instead of manually polling the database, subscriptions push changes instantly, reducing unnecessary network requests and latency.
