Ah seems this doesnt happen in module syntax, you instead get

Uncaught (in response) TypeError: Incorrect type for Promise: the Promise did not resolve to 'Response'.

Uncaught (in response) TypeError: Incorrect type for Promise: the Promise did not resolve to 'Response'.

So yeah go with

return fetch(request)

return fetch(request)

, it should be identical to not having the worker

Though ironically since this is an exception it does pass through if you execute

ctx.passThroughOnException()

ctx.passThroughOnException()

before returning nothing, but I dont recommend doing that

ErisaOP•6/14/24, 7:43 PM

ctx.passThroughOnException()

ctx.passThroughOnException()

is pretty useful if you dont want errors in your worker to affect traffic - I only dont recommend it if you plan to return nothing lol

similardisaster•6/14/24, 7:43 PM

am using it, was just curious if they provided a similar "passThrough()" method or equivelant

ErisaOP•6/14/24, 7:44 PM

Makes sense, yeah I've always seen and done

return fetch(request)

return fetch(request)

for that

may be worth mentioning I found out the hard way that's not foolproof lol, if you consume the body (of a request that does have a body) before the worker dies you're dead in the water

Chaika•6/14/24, 9:16 PM

oh wow 3 weeks ago they added that warning https://github.com/cloudflare/cloudflare-docs/commit/8fc09ccf816f7417d3e3d46852f74f34834ea15b
I just got unlucky when I tried it a while ago and found that out the hard way lol

similardisaster•6/14/24, 10:24 PM

interesting, thanks for raising that

similardisaster•6/14/24, 10:25 PM

i only want to "catch" get requests so might check method and pass through non gets

similardisaster•6/14/24, 10:25 PM

bit of a bummer that worker routes don't support wild cards in middle of route path, end up catching a lot of extra requests

Hey all. I am a PM on the Workers team. I'm doing some exploration into ways that people might want to use container-based workloads alongside Workers. If you are somebody who has wanted to use a container with Workers in some way, or has strong opinions on the topic, I'd love to chat! (Again, this is just an early exploration, so please don't get hopes up around something imminent!) - If you want to chat, feel free to book a time: https://calendar.app.google/qS8Dr4L2L2bWQ6726, or if you don't have time to chat, but have some use case for this that you'd love to see, feel free to drop it in a thread on this message. Thanks!

Hello awesome people, just wondering is there a way to load external/internal css file through worker :workers:

johtso•6/15/24, 9:44 AM

What's the deal with connection pooling of external fetch requests, does it just happen?

neoney•6/15/24, 6:06 PM

do you get a new worker for every fetch call?

neoney•6/15/24, 6:06 PM

asking to just know if its worth it to cache a variable for the "duration" of the worker

neoney•6/15/24, 6:07 PM

we have a ton of requests (often like 6 in a row from 1 pc) and they all do a kv read

neoney•6/15/24, 6:07 PM

drains it very quickly

neoney•6/15/24, 8:00 PM

wtf is the cache api

Nneoney wtf is the cache api

https://developers.cloudflare.com/workers/runtime-apis/cache/ A way to read/write to the Cloudflare CDN cache from within a Worker.

neoney•6/15/24, 8:30 PM

:thinkRoll:

neoney•6/15/24, 8:31 PM

isnt it meant to be used for actual like

neoney•6/15/24, 8:31 PM

site caching?

neoney•6/15/24, 8:31 PM

i dont want to cache the site, i want to cache 1 variable used by it

Unsmart•6/15/24, 8:31 PM

you can cache anything you want

neoney•6/15/24, 8:32 PM

huh

neoney•6/15/24, 8:32 PM

cool

neoney•6/15/24, 8:32 PM

ill look into it then

neoney•6/15/24, 8:32 PM

so this is wrong?

neoney•6/15/24, 8:32 PM

it doesnt return a response?

Nneoney it doesnt return a response?

Hello, I’m Allie!•6/15/24, 8:34 PM

It does return a Response. The trick is though, you can wrap your variable in a Response and cache it. It doesn't have to be a Response from an actual Web Server

neoney•6/15/24, 8:34 PM

Ok thanks

neoney•6/15/24, 8:38 PM

(you have to convert the variable to text to make it a response right?)

neoney•6/15/24, 8:38 PM

like cache new Response('some-value')

Nneoney (you have to convert the variable to text to make it a response right?)

Hello, I’m Allie!•6/15/24, 8:39 PM

Or like Response.json(someVal)Response.json(someVal)

Hello, I’m Allie!•6/15/24, 8:39 PM

Asuming your value is stringifyable

neoney•6/15/24, 8:39 PM

and i have to cache it with an actual url

neoney•6/15/24, 8:39 PM

cnai put any string there

neoney•6/15/24, 8:40 PM

cus says sttrings interpreted as the url

Nneoney cus says sttrings interpreted as the url

Hello, I’m Allie!•6/15/24, 8:41 PM

Basically anything that can be parsed as a URL. So https://google.comhttps://google.com should work, even though your value isn't actually being returned by Google

neoney•6/15/24, 8:41 PM

great

neoney•6/15/24, 8:41 PM

thats nice

neoney•6/15/24, 8:41 PM

oh and also, to set the actual like ttl of the value

neoney•6/15/24, 8:41 PM

i use the response headers?

neoney•6/15/24, 8:41 PM

i implemented a "cache" with kv and honestly this looks so portable to the cache api...
