This is a basic FastAPI application that demonstrates file uploads and downloads.

1. Create a virtual environment (optional but recommended):

   python -m venv venv
   source venv/bin/activate  # On Windows use `venv\Scripts\activate`

2. Install dependencies:

   pip install -r requirements.txt

Use uvicorn to run the application:

uvicorn main:app --reload

This will start the server, typically at http://127.0.0.1:8000.

• Navigate to http://127.0.0.1:8000 in your browser to see the welcome message.

• Navigate to http://127.0.0.1:8000/docs for the interactive API documentation (Swagger UI).

• Use a tool like curl or Postman to send a POST request to the /processfile/ endpoint with a file attached.

  Example using curl:

  curl -X POST "http://127.0.0.1:8000/processfile/" -F "file=@your_file_name.txt" -o output.txt

  Replace your_file_name.txt with the path to the file you want to upload. The processed (mocked) output will be saved to output.txt.
