# Stacks Health

## Key Paths
- Core package: `storage/framework/core/health/src/`
- Drivers: `storage/framework/core/health/src/drivers/`
- Notifications: `storage/framework/core/health/src/notifications/`
- Package: `@stacksjs/health`

## Source Files
```
health/src/
├── index.ts              # Re-exports drivers and notifications
├── drivers/
│   ├── index.ts          # Driver exports
│   └── ohdear.ts         # Oh Dear health check driver (WIP)
└── notifications/
    └── index.ts          # Health notifications (WIP)
```

## Current Status

**This package is WIP.** Current exports are placeholder markers:

```typescript
export const ohdearWip = 1              // Oh Dear driver placeholder
export const healthNotificationsWip = 1  // Notifications placeholder
```

## Built-in Health Endpoint

The health check functionality currently lives in the router, not this package:

```
GET /health
```

Returns:
```json
{
  "status": "ok",
  "uptime": 12345,
  "memory": { "rss": 1234567, "heapUsed": 987654 },
  "pid": 1234,
  "bunVersion": "1.3.0"
}
```

This endpoint is registered via `route.health()` in the router.

## CLI Commands

```bash
buddy doctor              # Comprehensive system diagnostics
```

## Planned Features
- Oh Dear integration for external health monitoring
- Health check notifications (email, Slack, etc.)
- Custom health check drivers
- Database connectivity checks
- External service status verification

## Gotchas
- **Package is WIP** — only placeholder exports exist
- **Health endpoint is in the router** — `GET /health` works via `route.health()`, not this package
- **`buddy doctor`** — system diagnostics are in the buddy CLI, not this health package
- **Oh Dear driver planned** — integration with ohdear.app for external monitoring
