Supabase Hello World

Overview

Minimal working example demonstrating core Supabase functionality.

Prerequisites

Completed supabase-install-auth setup
Valid API credentials configured
Development environment ready

Instructions

Step 1: Create Entry File

Create a new file for your hello world example.

Step 2: Import and Initialize Client

import { SupabaseClient } from '@supabase/supabase-js';

const client = new SupabaseClient({
  apiKey: process.env.SUPABASE_API_KEY,
});

Step 3: Make Your First API Call

async function main() {
  const result = await supabase.from('todos').insert({ task: 'Hello!' }).select(); console.log(result.data);
}

main().catch(console.error);

Output

Working code file with Supabase client initialization
Successful API response confirming connection
Console output showing:

Success! Your Supabase connection is working.

Error Handling

| Error | Cause | Solution | |-------|-------|----------| | Import Error | SDK not installed | Verify with npm list or pip show | | Auth Error | Invalid credentials | Check environment variable is set | | Timeout | Network issues | Increase timeout or check connectivity | | Rate Limit | Too many requests | Wait and retry with exponential backoff |
