Cookies generally don’t require user consent from a technical perspective, only a legal one

Hello, I’m Allie!•10/21/24, 1:28 PM

So if your server sends a set-cookieset-cookie, then the cookie will be set

Sort of? It is used in a different way, and it doesn’t support all of the selector magic that Cheerio has

Then why it was created?

LordSilver•10/21/24, 1:55 PM

Because Workers doesn't work with standard npm packages?

LLordSilver Then why it was created?

Hello, I’m Allie!•10/21/24, 4:11 PM

Because it is streaming. Workers may not have enough memory to hold an entire HTML DOM Tree in memory along with everything else. HTMLRewriterHTMLRewriter gets around this by streaming the body through, and never storing the entire thing in memory

Hello, I’m Allie!•10/21/24, 4:11 PM

This has some drawbacks, but for simpler manipulations it should be more than enough

D Trombett•10/21/24, 8:38 PM

It's a mix of native implementations and polyfills

D Trombett•10/21/24, 8:39 PM

So if something is implemented natively you'll get best performance but if something needs a polyfill it'll be slower

Hey, I am student. Attempting the Cloudflare Home Assignment for notification development. I am struck on invalid data validation or error handling of multiple notification. I am not sure what expectation I am missing. I don't want an direct answer I just want to know the expectations more clearly. Is there anyone here or a SPOC whom I can contact?

WillTolmie•10/22/24, 6:10 AM

What would the correct channel be for the Workers-Framework beta?

Constantin•10/22/24, 11:26 AM

having a problem with 2 workers: (1 - worker AapWorker), and another used as a service worker (2- AuthWorker).
when i set AuthWorker to use a remote KV (with preview_id, and run with wrangler dev --remote)

i'm getting this error in worker AppWorker

jazz1611•10/22/24, 12:32 PM

hello, how can i block access from *.worker.dev in my server/script ?

Jjazz1611 hello, how can i block access from *.worker.dev in my server/script ?

Cyb3r-Jak3•10/22/24, 1:22 PM

Add workers_dev = falseworkers_dev = false to your wrangler.toml file

jazz1611•10/22/24, 1:53 PM

my server are using nginx + php, some guys use domain *.worker.dev access to my site for exploit

jazz1611•10/22/24, 2:13 PM

so i need catch cf-worker header, right ?

Erisa•10/22/24, 2:17 PM

yes, block requests with a request header named cf-worker

jazz1611•10/22/24, 2:23 PM

got it. thank you

ac•10/22/24, 7:20 PM

Is there a hard limit to the number of service bindings a worker can have? I know there is 128 env variables/worker, but wondering specifically about service bindings since there's nothing on the limits page (https://developers.cloudflare.com/workers/platform/limits/)

time for bed, you guys are fast lol

Pedagogy•10/22/24, 10:03 PM

Hey all. New to Cloudflare workers and pages. I have a static website but would like to use a worker call for a request of a large image asset stored in Cloudflare R2. What are the best security practices for workers? I am assuming the worker is deployed publicly and the link is revealed to anyone who reads or scrapes my .js file. Is the best secuirty just CORS policies in the worker itself?

also how to quickly estimate costs as "Metrics" is not updating real-time for me?

Can you test/run your worker locally?

Enom•10/23/24, 2:11 PM

is there any tool that could real-time tell or output the correct cost/resource usage of the function? (CPU time)

Since, I assume that RPC is faster than Fetch (?) in latency
Do you guys know how much is it faster?

Any reason else for choosing RPC over FETCH? please share your thoughts

😈 Donkey 💫•10/23/24, 3:48 PM

Docs didn't point out any pros using RPC: https://developers.cloudflare.com/workers/runtime-apis/rpc/

Hello, I’m Allie!•10/23/24, 3:50 PM

I think it is mostly in the simplicity of use? You don't need to JSON.stringifyJSON.stringify data when you pass it around

😈 Donkey 💫•10/23/24, 3:51 PM

thanks, It doesn't require serialized data

�😈 Donkey 💫thanks, It doesn't require serialized data

Hello, I’m Allie!•10/23/24, 3:53 PM

The other thing too is that it might be faster because you aren't passing an entire RequestRequest/

since the last time I read docs, now It has pretty new things, like passing a stub/function, amazing

hey, just a quick one. is there an easy way to restrict access to my cf worker? it handles my emails (via resend) but everyone can access the provided url

Constantin•10/24/24, 12:56 AM

hey there, i'm getting

Cannot bundle Node.js built-in "events"

Cannot bundle Node.js built-in "events"

error when building a worker. Does events is missing from the CF workers runtime?

Henry Black•10/24/24, 1:49 AM

Is there an easy/quick way of checking the compatibility of a node package with the workerd runtime? Or perhaps a resource that lists Cloudflare compatible packages?

Constantin•10/24/24, 6:02 AM

@Henry Black there's this place https://developers.cloudflare.com/workers/runtime-apis/

Cloudflare Docs

Runtime APIs | Cloudflare Workers docs

The Workers runtime is designed to be JavaScript standards compliant

and web-interoperable. Wherever possible, it uses web platform APIs, so that code can be reused across client and server, as well as across WinterCG

JavaScript runtimes.
