Was the response created from any input to your handler? If so, that's why.

it was created from Response.redirectResponse.redirect with a string and integer literal

It is basically like keeping the Worker open the whole time, so normal time limits apply and you're billed even when not receiving messages.

No, that's not. Can you send me the incorrect URL please and I can escalate?

Oof, I see the problem there. Thanks

Where's the link that takes you there?

Has anyone had any luck getting skia canvaskit (or anything similar) working with workers? Theoretically it should work, but I was struggling to get the wasm bundle to work correctly with webpack. Some information about canvaskit: https://skia.org/docs/user/modules/canvaskit/ https://www.npmjs.com/package/canvaskit-wasm

Headers - Web APIs | MDN

The Headers interface of the Fetch API allows you to perform various actions on HTTP request and response headers. These actions include retrieving, setting, adding to, and removing headers from the list of the request's headers.

Is there any way to use the HTML Rewriter to move an element on the page?

rg•3/14/22, 5:31 PM

Have a question. Have a worker that caches images from origin. If an image is cached, does every request on a webpage count towards the worker request/usage quota? Since CDN is free with cloudflare, I am wondering if cached images are fetched from worker or the global cdn

AAggressiveInlining Workers run before cache. If you make images their own separate path from Worker...

rg•3/14/22, 7:06 PM

Not sure how to do that. Can you elaborate. Lets say I have an image in my html like:

html 
<a href="https://picsum.photos/200">someimage</a>

html 
<a href="https://picsum.photos/200">someimage</a>

my cloudflare worker currently pulls the remote image, saves it to cache. So how do I make images their own separate path from workers if they are remote?

AAggressiveInlining Say your workers are on a specific path like `example.com/api`, if you route you...

Responding mostly from memory in the DO basically means that you will be paying $0.15 for every million requests. How many requests do you expect to be getting?

How To Setup An Apollo GraphQL Server On Vercel

Erwin•3/14/22, 10:59 PM

I know some people have indeed.. but @Jacob | Pages has been doing some insanely fun work last week (week before?) on getting a regular GraphQL server working without the Apollo packages.. So it would depend a bit on what your requirements are.

The plan is absolutely to make it public.. although it currently is just a proof of concept, but if you ask Jacob nicely he might give you a sneak peek?

No, I'm trying to optimize the page by rearranging some scripts. Proving to be a bigger PITA than I thought

Luke•3/15/22, 6:36 AM

Yeah, I'm having the same sort of experience. I've tried making a class w/ some properties and storing the text from the elements but it looks like the elementelement method runs before texttext method so even after I've got the inner content it's too late :\ ah well, back to the drawing board

ilsubyeega•3/15/22, 7:45 AM

is it possible to get logs from crons without a realtime (requires websocket iirc) logging one, just for checking which error was thrown at cron

Kai•3/15/22, 9:44 AM

I found Apollo to be too bloated, I don't need any of their fancy cloud features. I went with GraphQL-Yoga (/common not /node), which is built on GraphQL-Helix which works great with the fetch request/response API you get in CF workers.

simpson•3/15/22, 11:42 AM

thanks! I'll check that out, any of your code public @kaijellinghaus ? It sounds like CF is working on a little GraphQL goodness in the labs

Kai•3/15/22, 11:53 AM

It's here https://github.com/LeagueML/cloudflare-api the graphql-yoga docs also have an example.
I haven't tested it extensively yet (not sure how well defer and stream work for example)

const body = await request.json()const body = await request.json() is how you access the POST body of a request

Isaac McFadyen•3/15/22, 2:47 PM

So in your case const { title, content } = await request.json()const { title, content } = await request.json()

i find it weird though how i cant modify headers even if the object was created myself
