Supabase Hello World
Overview
Minimal working example demonstrating core Supabase functionality.
Prerequisites
- Completed
supabase-install-authsetup - 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)
