Edge Function Setup

Supabase Edge Functions are server-side TypeScript functions running on Deno, deployed globally at the edge — closer to your users. They allow you to run backend logic securely, without managing traditional infrastructure.

NativeLaunch includes pre-configured Edge Functions for:

• User self-deletion
• AI Assistant (OpenAI integration)

This guide explains how to deploy and manage them inside your Supabase project.

Project Structure

Edge functions are located inside the supabase/functions directory:

supabase/
├── functions/
│   ├── user-self-deletion/
│   │   └── index.ts
│   └── ai-chat/
│       └── index.ts
├── migrations/
│   └── *****_remote_schema.ts
└── config.toml

Each folder represents one Edge Function.

1. Install Supabase CLI

Install the Supabase CLI:

npm install -g supabase

supabase --version

Login to your account:

supabase login

Link your project:

supabase link --project-ref your-project-ref

2. Configure Environment Variables

Some functions (such as the AI assistant) require secrets.

Set your OpenAI key securely:

supabase secrets set OPENAI_API_KEY=sk-proj-****

Never store API keys in the mobile application.

3. Deploy Functions

You can deploy a specific function:

cd supabase/functions

supabase functions deploy user-self-deletion

Or deploy the AI function:

supabase functions deploy ai-chat

4. Invoke the Function from App

The function is already integrated in the NativeLaunch template:

import {supabase} from '@shared/config/supabase'

export async function deleteUser(): Promise<void> {
  const {error} = await supabase.functions.invoke('user-self-deletion')

  if (error) {
    console.log('Error deleting user:', error)
    throw new Error(`Error deleting user: ${error}`)
  } else {
    console.log('User account deleted')
  }
}

Common Use Cases

Supabase Edge Functions are great for:

• Secure AI integrations (OpenAI)
• Custom auth logic
• Integrating 3rd party APIs
• Data processing
• Scheduled jobs

Deployment Strategy

Deploy safely:

# production
supabase functions deploy user-self-delete --project-ref your-production-project

Manage versions:

supabase functions deploy user-self-delete:v1
