# Supabase Client Import Standardization

## Summary
All Edge Functions now use consistent Supabase client imports from the same ESM source.

## Changes Made

### 1. get-directions/index.ts
**Before:**
```typescript
import { createClient } from 'jsr:@supabase/supabase-js@2'
```

**After:**
```typescript
import { createClient } from 'https://esm.sh/@supabase/supabase-js@2'
```

### 2. get-place-photo/index.ts
**Before:**
```typescript
import { createClient } from 'jsr:@supabase/supabase-js@2'
```

**After:**
```typescript
import { createClient } from 'https://esm.sh/@supabase/supabase-js@2'
```

### 3. generate-itinerary/index.ts
**Already using:**
```typescript
import { createClient } from 'https://esm.sh/@supabase/supabase-js@2'
```

## Benefits

1. **Consistent Module Resolution**: All Edge Functions now use the same import source, preventing potential version mismatches or module resolution conflicts.

2. **Reliable Deployment**: Using ESM.sh ensures consistent package resolution across all Deno deployments.

3. **Maintainability**: Single source of truth for Supabase client imports makes future updates easier.

4. **Compatibility**: ESM.sh is the recommended approach for Supabase Edge Functions and provides better compatibility with Deno's module system.

## Deployment Status

✅ get-directions - Deployed successfully
✅ get-place-photo - Deployed successfully
✅ generate-itinerary - Already using correct import

## Testing Recommendations

Test all three Edge Functions to ensure they work correctly with the standardized imports:

1. **generate-itinerary**: Create a new itinerary and verify place caching works
2. **get-directions**: Request route calculations and verify directions caching works
3. **get-place-photo**: Load place photos and verify storage caching works

All functions should continue to work as expected with improved consistency.
