I was going to post it manually with a fetch, as I just set up a server to gather pre-signed URLS etc, but not sure which direction is best

PutObject works up to 5 GB but you're at the whim of any network blip ruining that upload

Multipart is CreateMultipartUpload -> lots of UploadPart -> CompleteMultipartUpload with part numbers & ETags from earlier

It's a relatively simple flow, but you are responsible for tracking everything up until it's finished

whereas there's libraries that'll handle it all for you

Hey thanks for that

I was looking into Multer and BusBoy - those look workable, but i've never used them before

If you did want to implement it yourself, has some good pointers - but I'd definitely recommend a library that likely already comes with progress, retries, etc

I guess I'm concerned in having to build out effectively a relay server to work with CF if it's intended that I send everything there first.

Thanks for that - will take a look

What exactly is it that you're trying to send to R2, where does that file come from, etc

i.e user uploads then yeah, presigned URLs offload that work to the user rather than your server

If it's a file on-disk, just use

rclone

someone know way to set bucket permission by api? I can't find info about it

In this case, they are a user selecting a local file and uploading to R2. The files range in size from just a few 100Mb up to a few Gb

There's no public API for doing it so you can look at the API calls that the dashboard does but there's no forward notice of breaking changes if it isn't a documented API

PutObject will work up to 5GB, but it's not very resilient.

The issue with multipart (and presigned URLs) is that the user has to request each operation as a new URL from you

So it'll need one to start it, and one for each part, and one to complete it

Oops, this is V2

There's

Upload

in

@aws-sdk/lib-storage

If you can hack that together to use presigned URLs is another question

😦

There's probably a third party library that'll do it

I want to enable access to only one bucket by the API, there is any option to do so?

The only API token I can find is for all buckets, and I can't fine grind the permission to only one bucket.

Basically i want that each of my "customers" will have READ/WRITE access to their bucket.

Not currently, no

Good, now I'm sad!
