That's very nice, for comparison backblaze b2 has a request rate limit of double digits before it starts giving 429 errors

Same as gzip.

kian•11/10/23, 12:05 AM

Cloudflare will decompress it (if necessary) based on the client's Accept-Encoding header

Is anyone using R2 storage with Flutter or Dart?

I

iot•11/10/23, 5:20 AM

i uses R2 for storing media files for my production server (django rest API's ), mainly i do converting all types of files to pdf and saving in R2 storage, while converting jpg, png theree is no problem with that , but when i do for MS files (doc, docx, xls, xlsx, ppt, pptx) , it gives me problem.

I think there is issue with output file url ( as it seems path containg X-Amz-Algorithm=, X-Amz-Credential=, X-Amz-Expires=, X-Amz-SignedHeaders=host&X-Amz-Signature=)etc, please give me the solution, what should i do for that?

DigitalOcean Spaces has a limit of 500 req/sec per bucket and 1500 req/sec for all buckets.. so only R2 and S3 can compete on request rates

Question: Is there a way I can generate a presigned url with a custom Content-Disposition header?

Something like this?

const r2 = new AwsClient({
  accessKeyId: env.CF_ACCESS_KEY_ID,
  secretAccessKey: env.CF_ACCESS_KEY_SECRET,
})

const url = new URL(`https://${env.BUCKET_NAME}.${env.CF_ACCOUNT_ID}.r2.cloudflarestorage.com`)

url.pathname = obj.path
url.searchParams.set('X-Amz-Expires', `${60 * 60 * 24 * env.STRUCTURE_EXPIRY}`)

const _signed = await r2.sign(new Request(url, { 
  method: 'GET',
  contentDisposition: `attachment; filename="${obj.name}"`, // <------------------------ Something like this?
}), { aws: { signQuery: true } })
const signed = _signed.url

const r2 = new AwsClient({
  accessKeyId: env.CF_ACCESS_KEY_ID,
  secretAccessKey: env.CF_ACCESS_KEY_SECRET,
})

const url = new URL(`https://${env.BUCKET_NAME}.${env.CF_ACCOUNT_ID}.r2.cloudflarestorage.com`)

url.pathname = obj.path
url.searchParams.set('X-Amz-Expires', `${60 * 60 * 24 * env.STRUCTURE_EXPIRY}`)

const _signed = await r2.sign(new Request(url, { 
  method: 'GET',
  contentDisposition: `attachment; filename="${obj.name}"`, // <------------------------ Something like this?
}), { aws: { signQuery: true } })
const signed = _signed.url

const r2 = new AwsClient({
  accessKeyId: env.CF_ACCESS_KEY_ID,
  secretAccessKey: env.CF_ACCESS_KEY_SECRET,
})

const url = new URL(`https://${env.BUCKET_NAME}.${env.CF_ACCOUNT_ID}.r2.cloudflarestorage.com`)

url.pathname = obj.path
url.searchParams.set('X-Amz-Expires', `${60 * 60 * 24 * env.STRUCTURE_EXPIRY}`)

const _signed = await r2.sign(new Request(url, { 
  method: 'GET',
  contentDisposition: `attachment; filename="${obj.name}"`, // <------------------------ Something like this?
}), { aws: { signQuery: true } })
const signed = _signed.url

const r2 = new AwsClient({
  accessKeyId: env.CF_ACCESS_KEY_ID,
  secretAccessKey: env.CF_ACCESS_KEY_SECRET,
})

const url = new URL(`https://${env.BUCKET_NAME}.${env.CF_ACCOUNT_ID}.r2.cloudflarestorage.com`)

url.pathname = obj.path
url.searchParams.set('X-Amz-Expires', `${60 * 60 * 24 * env.STRUCTURE_EXPIRY}`)

const _signed = await r2.sign(new Request(url, { 
  method: 'GET',

const signed = _signed.url

Provide it in the headers for RequestInit.

K

kian•11/10/23, 9:28 AM

new Request(url, {
  headers: {
    'content-disposition': `attachment; filename="${obj.name}"`
  }
})

new Request(url, {
  headers: {
    'content-disposition': `attachment; filename="${obj.name}"`
  }
})

new Request(url, {
  headers: {
    'content-disposition': `attachment; filename="${obj.name}"`
  }
})

new Request(url, {
  headers: {
    'content-disposition': `attachment; filename="${obj.name}"`
  }
})

K

kian•11/10/23, 9:29 AM

you'd probably want to add

allHeaders: true

allHeaders: true

into the

aws

aws

block as well, next to

signQuery: true

signQuery: true

K

kian•11/10/23, 9:29 AM

that only signs it though - the client still has to provide it in the request

Hello !
Question: any way to assign a custom domain to a R2 bucket using the wrangler command line tool ?

N

NestarZ•11/10/23, 11:57 AM

Or some script that doesnt involve the web dashboard ?

Matt•11/10/23, 12:18 PM

Hi, quick question... if I've followed the steps to create a publicly accessible bucket... and everything looks "good": Public URL Access is Allowed, even threw in a test folder and file to make sure there is something there.. but I can't get in

E

Erisa•11/10/23, 12:22 PM

Are you visiting the direct path to a file? Theres no directory listing function so visiting a directory or the root / wont work

EErisa Are you visiting the direct path to a file? Theres no directory listing function...

M

Matt•11/10/23, 12:32 PM

thats excatly what i was doing

sorry new to this.. so there is no way for me to view the files in a bucket.. just a direct link to the file itself?

E

Erisa•11/10/23, 12:33 PM

Not with R2 itself, you would have to deploy a Worker that can do it (for the extra cost of worker requests) e.g. there is a popular one https://github.com/kotx/render/

E

Erisa•11/10/23, 12:35 PM

Yes

E

Erisa•11/10/23, 12:35 PM

Sure but you would have to visit /index.html or add a transform rule to rewrite to it

E

Erisa•11/10/23, 12:35 PM

And thats not R2 itself anymore either

E

Erisa•11/10/23, 12:40 PM

Yeah

E

Erisa•11/10/23, 12:40 PM

Prebaking adds some extra effort when organising and uploading the files, so just a game of tradeoffs as well, good callout

E

Erisa•11/10/23, 12:41 PM

Yes, the less simple part is creating and uploading index.html that match all your directories and keeping them updated

E

Erisa•11/10/23, 12:56 PM

Great

E

Erisa•11/10/23, 12:56 PM

feel free to publish it when youre comfortable doing that, would be a good resource
