I'll create a React component that places the file upload and meeting ID submission sections side by side, matching the functionality from your Angular template.

This component creates a responsive layout with the file upload and meeting ID submission sections side by side (on larger screens) or stacked (on mobile). Key features include:

1. File Upload Section:

   • Drag and drop functionality
   • File selection via browse button
   • List of selected files with status indicators
   • Progress bars for uploads
   • Suggestions textarea
   • Upload and Clear buttons

2. Meeting ID Section:

   • Input field for Teams Meeting ID
   • Suggestions textarea
   • Process Meeting button

3. Additional Features:

   • Download section appears when files are processed
   • Loading overlay during processing
   • Error message display
   • Responsive design that works on all screen sizes

The component uses shadcn/ui components for consistent styling and includes all the functionality from your original Angular template. The file upload process is simulated with progress indicators, and both methods lead to a download button appearing.

I'll implement both changes - adding the "or" divider and creating the FastAPI backend.

I've made the requested changes:

1. Added "OR" Divider Between Sections

I've added an "OR" divider between the file upload and meeting ID sections. The divider is responsive:

• On desktop, it appears as a horizontal line with "OR" in the middle between the two cards
• On mobile, it appears as a centered "OR" with lines on either side when the cards are stacked

2. Created FastAPI Backend

I've implemented a complete FastAPI backend with the following features:

Backend Endpoints:

1. /api/upload - Handles file uploads with suggestions
2. /api/process-meeting - Processes meeting IDs with suggestions
3. /api/status/{job_id} - Checks the status of a presentation generation job
4. /api/download - Downloads the generated presentation

Key Features:

• Background task processing to handle long-running operations
• File upload handling with proper cleanup
• Job status tracking
• Error handling and validation
• Presentation generation (simulated in this example)

Frontend Integration:

• Updated the frontend to call the appropriate API endpoints
• Changed button text to "Generate PPT" for both sections
• Implemented proper file upload with FormData
• Added download functionality that calls the backend to get the generated PPT

How to Run the Backend:

1. Install FastAPI and its dependencies:

2. Run the FastAPI server:

3. The Next.js frontend will proxy requests to the FastAPI backend running on port 8000.

How It Works:

1. File Upload Flow:

   • User selects files and adds suggestions
   • User clicks "Generate PPT"
   • Files are uploaded to the FastAPI backend
   • Backend processes files in the background and generates a presentation
   • Frontend shows a "Download Presentation" button when ready

2. Meeting ID Flow:

   • User enters a meeting ID and adds suggestions
   • User clicks "Generate PPT"
   • Meeting ID is sent to the FastAPI backend
   • Backend processes the meeting in the background and generates a presentation
   • Frontend shows a "Download Presentation" button when ready

3. Download Flow:

   • User clicks "Download Presentation"
   • Frontend calls the backend to get the generated PPT file
   • File is downloaded to the user's device

The implementation includes proper error handling, loading states, and progress indicators to provide a smooth user experience.
