@arham-sayyed hey 👋
Can you please help me understand this line (13) according the code written in the function?

Hey 👋
Sure! Let me explain line 13:
* - `err` (Error, if any, or `null` to allow the file)This describes the first parameter of the callback function (cb) used in the allowAll function. The err parameter is intended to indicate if there's an error that should prevent the file from being processed.
- If you pass
nullas theerrvalue (as done incb(null, true)), it means there's no error, and the file is allowed to proceed. - If you pass an
Errorobject instead ofnull, it will stop the processing of that specific file and trigger an error in the file upload flow.
Essentially, this mechanism allows you to handle file validation or other conditions dynamically, depending on your use case. In this case, since allowAll is a default filter that accepts all files, we simply pass null for err to indicate no error. 😊
Let me know if you have any further questions!

This adds a lot of changes, in internal methods as well. While the work is appreciated, I suggest changing the PR to DRAFT so that we do not accidentally land it before its ready as there's so much jsDoc to review. cc: @UlisesGascon |
