Supabase

Supabase is an open-source Backend-as-a-Service (BaaS) platform that offers features like a PostgreSQL database, authentication, real-time subscriptions, storage, and auto-generated APIs, making it a robust alternative to proprietary solutions like Firebase.

Key Features

  • PostgreSQL Database: Fully managed, scalable, and performant relational database.
  • Authentication: Secure user authentication with support for OAuth providers.
  • Realtime: Listen to database changes in real-time via WebSockets.
  • Storage: Manage and serve large files like images and videos.
  • Auto-generated APIs: Instant RESTful and GraphQL APIs based on your database schema.
  • Edge Functions: Deploy server-side functions close to your users for low latency.

Using Supabase

Authentication

  • Email & Password: Traditional sign-up and login.

Example: Sign Up a User

import { createClient } from '@supabase/supabase-js'
 
const supabase = createClient('https://api.polstudios.com', 'public-anon-key')
 
const { user, session, error } = await supabase.auth.signUp({
  email: 'user@polstudios.com',
  password: 'password123',
})

Database

Supabase uses PostgreSQL, allowing you to leverage its powerful features:

  • Tables and Relationships: Define tables with relationships.
  • Views and Functions: Create complex queries and stored procedures.
  • Full-Text Search: Implement efficient search functionality.

Example: Fetch Data from a Table

const { data, error } = await supabase
  .from('TimeActivity')
  .select('*')

Realtime

Listen to changes in your database in real-time:

supabase
  .from('TimeActivity')
  .on('INSERT', payload => {
    console.log('New todo:', payload.new)
  })
  .subscribe()

Storage

Manage user-generated content like images and videos:

  • Buckets: Organize files into buckets.
  • Access Controls: Define public or private access.
  • Direct Uploads: Upload files directly from the client.

Example: Upload a File

const { data, error } = await supabase.storage
  .from('avatars')
  .upload('public/avatar1.png', file)

Deployment and Scaling

Supabase handles the infrastructure, allowing you to focus on building your application. It offers:

  • Automatic Scaling: Handle increasing loads without manual intervention.
  • High Availability: Ensure your application is always accessible.
  • Backups and Recovery: Protect your data with automated backups.

Resources

Supabase simplifies backend development by providing essential services out-of-the-box, allowing developers to build and scale applications efficiently. Whether you’re building a simple app or a complex system, Supabase offers the tools and flexibility to meet your needs.
