great! one last question, is there any way to see analytics/access logs for requests sent to

<accountid>.r2.cloudflarestorage.com

similar to the data provided for bucket which uses custom domains?

If you're thinking of Web Analytics, then no, not currently (since that

<accountid>.r2.cloudflarestorage.com

domain does not belong to your account). The best you can do is look at the bucket-level metrics, but they might not be very useful, depending on your usage.

Hey I need to sign R2 bucket (which I've already done) and send the URL to FE. But what is the URL on local machine when I'm using miniflare?

It works perfectly alright in production where it uses the URL of an actual (not locally simulated) R2 bucket.

Signing as in S3 presigned URLs?

If so, there is nothing equivalent in Miniflare

Yeah and there is https://developers.cloudflare.com/r2/api/s3/presigned-urls/#presigned-url-alternative-with-workers but I don't think it can be used locally

Since, correct me if I'm wrong, miniflare doesn't expose local R2 url.

It's not related to Workers or Miniflare so no

They're not involved with the S3 API

There's nothing different about Workers vs Miniflare that'd stop you using presigned URLs

There is.. there's no local R2 for local development and automated tests in Docker.

I mean no local R2 URL

I'd have to create a bucket in Cloudflare dashboard where billing applies which is not what I want

Miniflare is only for testing Workers so yeah, it only has the R2 Workers API

Well it also locally simulates R2 and other services so one could argue it's also for testing those services from within Workers. So I've assumed since the logic is there why wouldn't the service be exposed on a local URL.

So basically if we want to use presigned URLs we HAVE to create a bucket in Cloudflare dashboard where billing applies. Currently there is no way to test it locally.

Did you put it behind a public domain and make sure Cloudflare’s cache is enabled for it?

How can I configure my R2 object for cloudflare's cache? It's a simple file and all users gets the same file (only GET)

check this example out as a starting place. It's what I used to do something similar https://developers.cloudflare.com/r2/examples/cache-api/

Better still: https://developers.cloudflare.com/r2/buckets/public-buckets/#caching

Hi, anyone know how to use "sip by sip migration" from S3 to R2 that is mentioned in this post? I can't find where to enable it https://blog.cloudflare.com/cloudflare-r2-super-slurper/

As far as I know, the only part that is out right now is "One giant slurp", which you can find in the CF dash under R2 -> R2 Migrator. Sip by sip is still being worked on

A Cloudflare Champ has made a worker to do such a thing if you're interested: https://github.com/KianNH/cloudflare-worker-s3-to-r2-migration (generic s3 -> r2 via a worker) Nothing official yet though,

Ok, got it, thank you so much for clarify. Maybe they could add a note in the blog

Download :: 705 Mbits/s Upload :: 764.38 Mbit/s

and I'm also using rclone beta

@HardAtWork Is there another way to bulk upload assets (json) faster in r2?

there are ~300k json files

aws s3 sync

gives just 20 KiB/s
