Identifies sync functions in Django views and suggests async conversion patterns to avoid blocking the event loop.

Async conversion suggestions

Run the tool to see output.

Examples

Sync View Conversion

{
  "code": "def my_view(request):\n    data = fetch_data_sync()\n    return HttpResponse(data)",
  "async_suggestions": true
}

Expected output

Suggested async conversion: async def my_view(request): data = await fetch_data_sync()
Replace fetch_data_sync() with async version

Blocking Operation Detection

{
  "code": "def expensive_operation(request):\n    time.sleep(5)\n    return JsonResponse({})",
  "async_suggestions": false
}

Expected output

Warning: Blocking operation detected in expensive_operation. Use asyncio.sleep() instead.

How it works

Analyzes input code for sync functions, detects blocking operations, and provides actionable async conversion suggestions without requiring external dependencies.
