Supabase Core Features and Benefits

Supabase provides a range of services to streamline backend development. The following are the core features and benefits of Supabase.

1. Database Management: Supabase offers a fully managed PostgreSQL database with SQL query support, advanced indexing a built-in query editor, and schema visualization tools.

2. Authentication: Secure user authentication with support for email/password, OAuth providers, and third-party authentication integrations.

3. Real-time Capabilities: Supabase offers real-time data synchronization using PostgreSQL's replication engine.

4. Storage: Provides scalable file storage with secure access and seamless integration into applications.

5. API Auto-generation: Automatically generates RESTful APIs for all database tables and views. This saves time by using APIs that are instantly ready for CRUD (Create, Read, Update, Delete) operations.

6. GraphQL Support: Supabase supports GraphQL for flexible and efficient queries of complex data structures.

Configure Supabase

After deploying Supabase on Vultr, you must configure essential settings to secure and optimize your instance. This includes updating API keys to enhance security and ensure proper authentication for database access. Supabase generates default keys during deployment, but regenerating them prevents potential security risks.

Update Supabase API Keys

Supabase generates a JWT Secret during deployment, which you can use to regenerate the Anon and Service Role API keys. These keys authenticate your requests to Supabase and provide secure access to your database. You need to regenerate the keys to ensure security and proper authentication, as the default keys can become outdated or compromised. Follow the steps below to update your API Keys.

1. SSH into your Supabase instance and create a new directory. Replace supabase-project with your preferred name.

   CONSOLE

   Copy

   # mkdir supabase-project

8. Add the following javascript code to the generate_keys.js file. Replace your_jwt_secret with the Supabase JWT secret you have copied.

   JAVASCRIPT

   Copy

   const jwt = require('jsonwebtoken');
   
   // Replace with the JWT you copied
   const SUPABASE_JWT_SECRET = "your_jwt_secret";  
   
   const payloadAnon = {
     role: "anon",
     iss: "supabase",
     iat: Math.floor(Date.now() / 1000),
     exp: Math.floor(Date.now() / 1000) + 60 * 60 * 24 * 365 
   };
   
   const payloadServiceRole = {
     role: "service_role",
     iss: "supabase",
     iat: Math.floor(Date.now() / 1000),
     exp: Math.floor(Date.now() / 1000) + 60 * 60 * 24 * 365 
   };
   
   // Generate tokens
   const anonKey = jwt.sign(payloadAnon, SUPABASE_JWT_SECRET, { algorithm: "HS256" });
   const serviceRoleKey = jwt.sign(payloadServiceRole, SUPABASE_JWT_SECRET, { algorithm: "HS256" });
   
   
   console.log("ANON_KEY=", anonKey);
   console.log("SERVICE_ROLE_KEY=", serviceRoleKey);

Optional: Access Supabase PostgreSQL Database

When you deploy Supabase Marketplace Application on Vultr, a default PostgreSQL database is automatically created. This database serves as the backend for your application, handling data storage, authentication, and queries. You can find the PostgreSQL login credentials in the App Instructions section of your Vultr instance and use them to connect directly to the database.

1. Navigate to the App Instructions section of your Supabase instance, and note the PostgreSQL database login credentials.

   

2. Connect to the PostgreSQL database using the following PostgreSQL connection string format.

   postgres://<user>.<pooler_tenant_id>:<password>@<host>:<port>/<database>

   Replace the placeholders with your credentials:

   • user: Your PostgreSQL database user
   • pooler_tenant_id: Your tenant ID (found in your Supabase .env file)
   • password: Your PostgreSQL database password
   • host: Your Supabase instance IP address
   • port: Default PostgreSQL port, 5432
   • database: Default database, postgres

   Note

   The pooler tenant ID is required for authentication when connecting to a Supabase database deployed via Docker, including the Vultr Marketplace version. Without it, authentication will fail.

3. To find or update your pooler tenant ID, navigate to your Supabase docker directory:

   CONSOLE

   Copy

   # cd /home/supabase/supabase/docker/

   Explain Code

   Powered by Vultr AgentBeta

4. Open the .env file.

   CONSOLE

   Copy

   # nano .env

   Explain Code

5. Look for the POOLER_TENANT_ID variable and update it with your preferred ID.

   POOLER_TENANT_ID=your-tenant-id

6. To apply the changes, you need to remove and recreate the Supabase containers.

   1. Remove the Supabase containers.
