Fun API things, on the bottom left of that page you can click "Give feedback" and submit the issue

On Request it's RequestInitCfProperties created requests and IncomingRequestCfProperties for requests your worker receives, types documented here: https://developers.cloudflare.com/workers/runtime-apis/request/#incomingrequestcfproperties

Request · Cloudflare Workers docs

The Request interface represents an HTTP request and is part of the Fetch API.

Hi I'm new to CF Workers API,
in my attempt to use the api to create a new worker (https://developers.cloudflare.com/api/operations/worker-script-upload-worker-module) I made it work but the Routes section under it is not activated by default (but this is automatically activated when I use the dashboard)
Can you guys guide me more on this to get it active automatically when calling the API?

Hey, we're aware and working on it

Awesome as always!

McSneaky•7/5/23, 7:29 PM

Seems like you can't make workers currently?

McSneaky•7/5/23, 7:29 PM

McSneaky•7/5/23, 7:29 PM

That's all I'm getting as soon as I click "Create" button

McSneaky•7/5/23, 7:31 PM

Maybe that's lil bit more useful screenshot

Also happens when you click on "Manage application"

Walshy•7/5/23, 7:42 PM

also fine

McSneaky•7/5/23, 7:42 PM

Hmm

McSneaky•7/5/23, 7:42 PM

Still broken for me

McSneaky•7/5/23, 7:43 PM

Lemme try to create another one

Walshy•7/5/23, 7:43 PM

you refreshed the whole dash?

McSneaky•7/5/23, 7:43 PM

Jup, hard refresh with cache disabled

AKStriker98•7/5/23, 7:43 PM

Quick question. I’m testing a script with wrangler dev —remote and all of my curl requests and fetch requests to the ip is returning 403. Loading the local host and port returns a 401 (correct behavior). Any guesses as to why?

Walshy•7/5/23, 7:44 PM

what's the response body?

AKStriker98•7/5/23, 7:45 PM

^note, 403s are occurring before the async fetch is called.

Response body is error code:1000

McSneaky•7/5/23, 7:45 PM

@Walshy | Pages can I PM you with video?

AKStriker98•7/5/23, 7:51 PM

And to further clarify, it’s the browser opening from the wrangler dev terminal is what’s behaving correctly. Non-browser traffic doesn’t work in dev or when pushed up to a test environment

Is buffering a ~25MB ReadableStream to an ArrayBuffer safe?

kian•7/5/23, 9:45 PM

For 1 request? Sure
For 6 concurrent requests? Not so much

Kkian For 1 request? Sure For 6 concurrent requests? Not so much

dave•7/5/23, 9:53 PM

I don't control that though, this is an incoming request.

kian•7/5/23, 9:56 PM

Isolates (of which will handle concurrent requests) are what has the memory limit so you might be able to buffer 25MB but if that isolate gets enough concurrent requests you can run into eviction due to exceeding the memory limit

gonz•7/5/23, 10:25 PM

we went live yesterday with our Fastly to Cloudflare migration and so far working very nicely

only thing I'd like to improve is that we're doing like ~200 requests a second... thinking I need to make more client-side cache changes to avoid so many requests to the workers

hey, can i access my R2 bucket in local mode or is that not possible?

James•7/5/23, 11:52 PM

Not possible in local mode unfortunately. You will have to use

wrangler dev --remote

wrangler dev --remote

to access "real" buckets, KV namespaces, etc.

im assuming

wrangler dev --remote

wrangler dev --remote

will fix my problem

mathusan•7/6/23, 3:27 AM

i'm not sure if this is the correct channel to ask, but anyone know the status of the workers browser rendering API (https://www.cloudflare.com/lp/workers-browser-rendering-api/)? I have a great usecase for it for a project that I'm working on and would love to get my hands on it :). Seems to be in private beta at the moment.

Hyper•7/6/23, 4:15 AM

Hey guys. Ive been in a long and tedious process of migrating our express (node) backend to workers. Ive accomplished a lot but now im stuck in formatting images. Previously, i used sharp (a node library) to convert images from jpg to png and pipe the stream to R2 through the S3 wrapper (which was a one liner). Ive tried to accomplish this in my worker using JIMP, image-js, and other libraries but was unable to get it working (presumably due to the lack of support for the canvas api in workers). How would I go about simply converting a jpg image to png in my worker?

Palash Bansal•7/6/23, 7:27 AM

image-js works without canvas on cloudflare workers, what error are you getting
for jpeg encoding in image-js I had to import Buffer and set it to self.Buffer globally.

Erwin•7/6/23, 8:33 AM

Does anyone know why

Buffer

Buffer

is not set in global scope with the

node_compat

node_compat

flag set? To be able to use NodeJS libraries, especially ones that

Buffer

Buffer

in top level scope with ESM loading, requires some pretty ugly hacks with importing a "polyfill" type file that imports

, set it in the global scope, and then need to make sure it doesn't get tree-shaken out.

BlackForestBoi•7/6/23, 9:29 AM

hey folks, I am a bit confused in which state the browser rendering API is and how to get access?
On the blog (https://blog.cloudflare.com/browser-rendering-open-beta/) it says open beta, but still says "we need to sign up for a wait list" (did that)

What is the process now and whats the usually wait time until we can use it?

Thanks!
