# Supabase Setup and Usage Guide

## Prerequisites for running Supabase:
- Docker Desktop (or Docker Engine + Docker Compose on Linux)
- Supabase CLI

## Installation

1. **Install Supabase CLI**
   ```bash
   # Using NPM
   npm install -g supabase
   
   # Using Homebrew (macOS)
   brew install supabase/tap/supabase
   ```

2. **Start Supabase locally**
   ```bash
   # Navigate to your project
   cd ElatoAI
   
   # Start Supabase local development
   supabase start
   ```

3. **Verify installation**
   The output should show local endpoints including:
   - API URL: http://127.0.0.1:54321
   - Studio URL: http://127.0.0.1:54323
   - JWT secret: super-secret-jwt-token-with-at-least-32-characters-long

## Configuration

1. **Environment variables**
   Add these to your `.env.local` and `.env` file in `frontend-nextjs` and `server-deno` respectively:
   ```
   SUPABASE_URL=http://127.0.0.1:54321
   SUPABASE_KEY=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...
   JWT_SECRET_KEY=super-secret-jwt-token-with-at-least-32-characters-long
   ```

## Tables
1. `users` - user details are stored here
2. `devices` - device details (mac address, device name, etc) are stored here
3. `conversations` - conversation details (start time, end time, etc) are stored here
4. `messages` - all conversations and transcripts are stored here
5. `api_keys` - api keys are stored here (not used for local development)
6. `languages` - all supported languages are stored here


## Development Workflow

1. Make schema changes in Supabase Studio (http://127.0.0.1:54323)
2. Generate migrations: `supabase db diff -f <migration_name>`
3. Apply to local database: `supabase migration up`
4. Push changes to production when ready

## Deploying to your own supabase instance

1. Create a new supabase project
2. Copy the supabase url and anon key
3. Paste them in the `.env` and `.env.local` file in the root of the project
4. Link the project to the new supabase instance: `supabase link --project-ref <project_ref>`
5. Run `supabase db push --include-seed` to push the changes to the local database and seed the database with the data in `supabase/seed.sql`

## Stopping Supabase

```bash
supabase stop
```
