Thanks from me too, and also thank you kian for reporting this since I have no idea how to do this

In the meantime, if you still want to get rid of it, right-click the request and click on "Edit and Resend" - on the left, in the Headers box, change

cf-r2-jurisdiction

cf-r2-jurisdiction

from

to

and click on Send.

K

kianOP•11/2/23, 6:55 AM

R2 doesn't have that functionality

I'm trying to get a R2 file list in a worker, how to do that?

B

bz_008•11/2/23, 7:17 AM

here's my code:
const olist: R2Object[] = await env.MY_BUCKET.list();
const slist: string[] = olist.map((o)=>o.key);
it says TypeError: olist.map is not a function

K

kianOP•11/2/23, 7:34 AM

It returns

R2Objects

Hi everyone, I have a question about R2 and the free egress fee.

If I use R2 to store audio files with public access enabled, would the transfer flow be from R2 to the client? Additionally, in this setup, would I only be charged for storage and the number of requests, with egress to the client being free of cost?

K

kianOP•11/2/23, 7:43 AM

Yes and yes

Kkian Not `R2Object[]`

B

bz_008•11/2/23, 7:59 AM

Thanks for the help, I checked the link, it says it's "An object containing an R2Object array, returned by BUCKET_BINDING.list()." interesting..
So, how to get the R2Object array out?

Kkian Yes and yes

Gordon•11/2/23, 8:03 AM

Thanks for the reply. I have a follow-up question.

From the document: https://developers.cloudflare.com/r2/buckets/public-buckets/
It states that to enable public access for R2, I must set up a custom domain, as the r2.dev domain is for development purposes only. However, it appears that after setting up a custom domain, the flow will be: R2 -> CDN -> client. I'm not sure if I've misunderstood anything. Will I be charged for the data transfer from the CDN to the client?

kianOP•11/2/23, 8:03 AM

Nope

kianOP•11/2/23, 8:03 AM

The CDN will lower your bill since cached requests don't incur R2 operations

Cool, that works.. on R2Objets, thank you!

ray.dev•11/2/23, 8:23 AM

Hi kian,
I have the same question today. I am only using R2 without Cloudflare CDN. When I am using a custom domain, the Cloudflare will enable free CDN for me regardless of egress traffic, does that make sense?

If it is the case, say I have 1 pb egress traffic per month, will the Cloudflare charge us by egress traffic rather than orignal plan

R

ray.dev•11/2/23, 8:25 AM

I am still assessing whether to use R2

R

ray.dev•11/2/23, 8:38 AM

Thanks! Do you know any cases that people got charged after exceeding some amount of traffic like 500TB

R

ray.dev•11/2/23, 8:38 AM

or something like that

You can use an unlimited amount of bandwidth for free without upgrading. Do note that you can get an enterprise agreement where you can negotiate pricing details and normally all bandwidth is charged there but other costs can be decreased by usage amounts.

K

kianOP•11/2/23, 7:05 PM

Do you have a URL that should be showing the headers?

this is my code.

const express = require("express")
const multer = require("multer")
const cors = require("cors")
const {S3Client, PutObjectCommand} = require("@aws-sdk/client-s3")
const dotenv = require("dotenv")

const app = express()
const port = 3000

// middleware
app.use(cors())
dotenv.config()

const storage = multer.memoryStorage()
const upload = multer({
storage,
})

app.get("/", (req, res) => {
res.send("Hello World!")
})

app.post("/upload", upload.single("file"), async (req, res) => {
// console.log(req.file)
// res.send("File Upload")
const S3 = new S3Client({
region: "auto",
endpoint: process.env.ENDPOINT,
credentials: {
accessKeyId: process.env.R2_ACCESS_KEY_ID,
secretAccessKey: process.env.R2_SECRET_ACCESS_KEY,
}
})

await S3.send(
new PutObjectCommand({
Body: req.file.buffer,
Bucket: "fullstack-team",
Key: req.file.originalname,
ContentType: req.file.mimetype

)
res.send("File Upload")

As the control plane for many services is degraded right now its quite possible that your changes haven't been applied yet.

I mean, now that transfer-encoding is chunked, make a lot of sense, but why it wasn't earlier?
