Stream File Uploads Directly to Disk to Prevent Memory Overload

[ahmadnasriya]

Currently, the bodyParser function accumulates the entire request body into memory, which can cause significant memory usage, especially when handling large file uploads. This can lead to performance degradation and potential server crashes.

Task:

Refactor the file upload handling process to stream files directly to a temporary location on disk as they are being uploaded. Once the upload is complete, move the file to its final destination.

Steps to Implement:

1. Modify the request handler to stream the incoming file data directly to disk, rather than accumulating it in memory.
2. Ensure that the stream handles errors gracefully and that partially uploaded files are cleaned up.
3. Implement a function to move the file from the temporary location to the final destination once the upload is complete.
4. Update existing unit tests and add new tests to cover the streaming and file-moving logic.

Expected Outcome:

The server should handle file uploads more efficiently, preventing memory overload and maintaining server performance.
