[@Lucifer-os4iv]

Please make a video on uploading folders which contains folders inside of it, and then creating those folder structures on server also.
Just like Google drive does.

[@Cdswjp]

I don't understand how come it makes more sense to 1st save the files to the tmp directory & to then save them again to the uploads directory. It sounds counterintuitive because now we're saving them to 2 directories instead of just 1.
I would think that it's more efficient to remove the 1st step of saving the files to tmp first.
How come this isn't so?

[@sudeepkotari]

@@mafiacodes tq mittal yours tutorials and best practices are helping so much in my first job

[@faris.abuali]

Thanks a million!
Summary of the error handling in case of multiple files upload:
- We can use try...catch for synchronous code only.
but since the file.mv() function is async function, then it will return a promise, and this promise if rejected, it should be caught inside the forEach(async (file) => {
}) itself.
So that's why we decided to store all returned promises of file.mv() inside an array called promises[ ], then execute them outside the forEach() context.
await Promise.all(promises); //execute the stored promises.
This makes the code cleaner and ensures that any expected error while uploading the files will be caught.
Am I right?

[@mafiacodes]

You nailed it, absolutely right 🚀

[@selvavigneshr9621]

hi can you explain how can we do this using mongo db for storing files ?

[@mafiacodes]

You should not use mongodb to store files, instead use a bucket to do so, and simply store references of those files in mongodb
