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

Examples

TypeScript Example

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

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

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

main().catch(console.error);

Python Example

from supabase import SupabaseClient

client = SupabaseClient()

response = supabase.table('todos').insert({'task': 'Hello!'}).execute(); print(response.data)
