When uploading a large file, is it correct to use module nginx file upload or is js on the client sufficient?

Question

PHP

resumable2/resumable.js transfers the file in chunks
. For example, uploads large files.
There is a package for it
https://github.com/dilab/resumable.php
There is a download on the server through the module nginx file module.
I don't understand what is the best way to use it.
Why is the loading module built into the server at all?

Answer 1

Because writing 10 lines to the nginx config is much faster and easier and more reliable. Yes, and it will work a little faster. And then there are those who do not have a backend at all, only nginx.
If you need tricks when loading, such as progress or filtering and post-processing of files, then you cannot do without a backend.
