Hi,

Also, I do not get why there is a whole part on S3 in the doc? Is it just that it is the exact same signature or will files actually be put on S3

R2 serves an S3-compatible API, the data will be on R2 but the signature and API are the same as S3 so any S3-compatible libraries will work

And finally, is there a Node JS SDK that would ease the use, I could not find an official one

We provide official examples for

aws-sdk-js

aws-sdk-js

: https://developers.cloudflare.com/r2/examples/aws/aws-sdk-js/

aws-sdk-js-v3

aws-sdk-js-v3

: https://developers.cloudflare.com/r2/examples/aws/aws-sdk-js-v3/

aws4fetch

aws4fetch

: https://developers.cloudflare.com/r2/examples/aws/aws4fetch/

But theoretically any library compatible with S3 and that supports changing the endpoint will work fine since the API is compatible

Thanks I did find the wording obvious but it works now

Unsmart•7/14/23, 6:59 PM

Dont think you can. Could use a worker + the cache API though

Tanjirokamado•7/14/23, 8:11 PM

Can I stream video from R2 storage in my web site using workers and what will be the limitation

Unsmart•7/14/23, 8:59 PM

Yes you can use R2 for video content

I am sorry. I'm posting a video stream. https://cdn.anizium.com/demon-slayer-1-1-2160-jp.mp4 is my sample link. It works fine in all browsers, but I get an error on iOS devices.

Kvothe•7/14/23, 10:25 PM

I read in a few places that it might be related to cors policy.

Chaika•7/14/23, 10:27 PM

If you're going to the mp4 directly and not trying to load it on an external site it's not related, it doesn't load for me in Firefox either, looks like the mp4 is somehow corrupt or just unreadable by mozilla's mp4 as well

ErisaOP•7/14/23, 10:27 PM

Its 1.47 GB and cacheable, I wonder if its the cache bug mentioned a couple times in this channel

Kvothe•7/14/23, 10:31 PM

but it works for me and it's ok. I don't think this has anything to do with caching. I couldn't find the problem either.

Unsmart•7/14/23, 10:31 PM

Im assuming safari/firefox do range requests on mp4 files which would make it a cache issue

ErisaOP•7/14/23, 10:32 PM

in chromium it works but the range requests dont, I suspect^ the other browsers are relying on this behaviour

Kvothe•7/14/23, 10:32 PM

Can you try from chrome? I'm working too. I do not think that there will be a problem due to the file or the installation. If you wish, I can download bunny.mp4 and try it.

ErisaOP•7/14/23, 10:32 PM

Its because the file is too big to be cacheable, please bypass cache for it

Kvothe•7/14/23, 10:33 PM

how do i bypass the cache?

We can find out about the problem here. I'll skip the cache by the way, that's on my mind. https://cdn.anizium.com/Big_Buck_Bunny_1080_10s_30MB.mp4 there is a small image in this link. i am getting the same error.

ErisaOP•7/14/23, 10:35 PM

That second link works for me on both Firefox and Safari iOS without any errors

ErisaOP•7/14/23, 10:35 PM

this is because its small and fits within the cache

My tests using

Soham•7/15/23, 3:07 PM

does caching occur if the contents of R2 are accessed through a worker with a route?

kian•7/15/23, 3:41 PM

Nope

kian•7/15/23, 3:41 PM

You can add the Cache API yourself but you'd still be billed for the Worker invocation

Soham•7/15/23, 5:36 PM

ah ok

Kvothe•7/15/23, 10:27 PM

You could make a more complex rule, perhaps only bypassing for a specific subfolder (i.e Path Starts With /videos) or even specific files with a full path match, so that you only bypass cache for large videos. Although if everything you have is large videos it won't matter

So, yes, it does expose my bucket name and the account ID. Is that safe? Bucket name doesn't seem to be a big deal as it's same as my domain. But is ACCOUNT_ID safe to be exposed?

Yes, it's fine.

Note that I do have Custom Domains setup on this bucket. Can I just replace the BUCKET_NAME.ACCOUNT_ID.r2.cloudflarestorage.com part of the presigned url with my custom domain? Would that still validate the signature?

Nope, custom domains don't implement the S3 API.
