1. Frontend: Chunked Upload with Progress Split the file into chunks. It makes it easy for resumable uploads and retry of failed chunks. Use XMLHttpRequest with progress events to track the upload percentage on each chunk. Display this to the user.

2.Backend Stores Upload State Keep track of uploaded chunks in a DB or cache (e.g., Redis). When all chunks are uploaded, merge them into a final file.

3. Retry Logic On the frontend, Retry failed chunks using exponential backoff. If a chunk fails 3 times, show a retry button to the user. 4. Final Assembly & Validation Once all parts arrive, validate and stitch the file back together on the server.

In real-world scenarios, always use cloud storage (like S3 or GCS) for file uploads. Why? Direct uploads to your backend can overwhelm your server. With pre-signed URLs, clients upload straight to the cloud reducing server load and improving speed and scalability

@mysticwillz My answer: I don't know how to explain, but I can do it.

@SuperOlami lol, Now you know how

@mysticwillz Chunked uploads are the way to go, right? Makes it way easier to handle large files and network hiccups.

@mysticwillz Chunked uploads are the way to go, right? That way you can track progress on each chunk and retry if needed. Good question for an interview!

@mysticwillz Very useful. Merci
