im using js not ts so i don't have access to the Env interface

SSenti3ntB3ing im using js not ts so i don't have access to the Env interface

Hello, I’m Allie!•5/2/25, 2:27 PM

You just do env.FIREBASE_SECRET

Hello, I’m Allie!•5/2/25, 2:27 PM

Whether TypeScript or JavaScript

Senti3ntB3ingOP•5/2/25, 2:30 PM

i've been doign that tho, it still shows up undefined

Senti3ntB3ingOP•5/2/25, 2:30 PM

i only recently changed it to process.env to try to get around it

Ollie•5/2/25, 2:31 PM

then its not set in your secrets, if you have not added it as a secret, then standard env vars get reset on each deploy (unless they are in your wrangler config file)

Senti3ntB3ingOP•5/2/25, 2:32 PM

i have them both set in wrangle.jsonc and set in my dashboard secrets, as well as thru npx wrangler secret put NAME

Senti3ntB3ingOP•5/2/25, 2:32 PM

none of the methods has let me use them

Ollie•5/2/25, 2:33 PM

maybe log out the entire

env

env

object to see whats on it

Senti3ntB3ingOP•5/2/25, 2:33 PM

Senti3ntB3ingOP•5/2/25, 2:47 PM

no idea what happened between then and now, i logged the env object once and now its working every time

Senti3ntB3ingOP•5/2/25, 2:48 PM

literally changed nothing else in my code

@Hard@Work do you have any thoughts here? Are DO's really the only way?

Hello, I’m Allie!•5/3/25, 12:22 AM

If it isn’t working now, I would probably try with DOs

Hello, I’m Allie!•5/3/25, 12:24 AM

Maybe try it with a little bit of traffic, rather than shifting the entire app over, in the event it doesn’t work

IdkWhatever69•5/3/25, 5:19 AM

suddenly all requests are being cancelled to my worker

IdkWhatever69•5/3/25, 5:19 AM

any idea?

IdkWhatever69•5/3/25, 5:21 AM

IdkWhatever69•5/3/25, 5:21 AM

i did not touch a thing in 8 months

IIdkWhatever69 any idea?

Chaika•5/3/25, 5:24 AM

Cancelled usually means the client gave up due to timeout/too slow

dave•5/3/25, 2:22 PM

Does setting both "upload_source_maps": true"upload_source_maps": true and "minify": true"minify": true work? Or will source mapping be broken?

Kenneth Solberg•5/3/25, 2:23 PM

would be cool if Images supported predefined templates (variants) for url transformations of images from external zones ... like bunny.net does

Hello, I’m Allie!•5/3/25, 4:48 PM

It should definitely work

HHello, I’m Allie!It should definitely work

dave•5/3/25, 5:15 PM

Any downsides?

Also, why isn’t minify the default?

Ddave Any downsides? Also, why isn’t minify the default?

Hello, I’m Allie!•5/3/25, 5:23 PM

Downsides for Minify? I guess that you can’t edit via the Dashboard, which some prefer for quick fixes?

HHello, I’m Allie!Downsides for Minify? I guess that you can’t edit via the Dashboard, which some ...

dave•5/3/25, 5:26 PM

Ah right. I’m using TypeScript, so quick edits are already not a thing.

Senti3ntB3ingOP•5/3/25, 6:34 PM

can i use post requests to change items on a workers display page?

Senti3ntB3ingOP•5/3/25, 6:34 PM

is there an example somewhere i can take a look at if so?

filyys•5/3/25, 6:35 PM

Hi, quick question, I don't want to create a post for this as it's a yes or no, but do I have use something like KV storage to store a single persistent variable in a worker? There's no simpler way of doing this?

Ffilyys Hi, quick question, I don't want to create a post for this as it's a yes or no, ...

Cyb3r-Jak3•5/3/25, 6:48 PM

What do you mean by persistent variable? You can use definedefine but that is only set at build time

filyys•5/3/25, 6:49 PM

All I need is for it to not change. Workers can periodically restart afaik and I can't have it change the content of the variable

filyys•5/3/25, 6:49 PM

Soooo I was going to use KV storage for that, but one variable for that seems over-complicated

SSenti3ntB3ing can i use post requests to change items on a workers display page?

Cyb3r-Jak3•5/3/25, 6:49 PM

You can use the REST API to make changes to workers

Cyb3r-Jak3•5/3/25, 6:52 PM

You might want to use Durable Objects as KV storage isn't consistent

filyys•5/3/25, 6:53 PM

Okay, thanks for the guidance

Senti3ntB3ingOP•5/3/25, 6:55 PM

i'm looking more for changing the content of the page its serving - in the defauly example they give while setting up the worker, we make a few fetch GET requests to other endpoints of the worker to retrieve random UUID and change the html content of the page

Senti3ntB3ingOP•5/3/25, 6:56 PM

what i'm looking to do is send a request to another endpoint of my worker, which sends a request to external domain, which sends a callback to a different endpoint of my worker, which i would want to then send a post req to the original page

Senti3ntB3ingOP•5/3/25, 6:57 PM

Senti3ntB3ingOP•5/3/25, 6:57 PM

like this

Senti3ntB3ingOP•5/3/25, 7:09 PM

i think im overthinking it, i think i can do this

Niveth•5/4/25, 8:09 AM

Is it possible to deploy an worker and make it accessible only through my laptop.

similar to how tailscale does this

kaelys.js•5/4/25, 6:18 PM

How long should it take for a worker to spin up puppeteer (cold start) (browser rendering) and hit a single URL and return the content typically? Excluding website loading time of course.

kaelys.js•5/4/25, 6:19 PM

I’m trying to use a combination of browser rendering + queues + do to build a crawler for our internal use. Done the bulk of it. Should the browser instance live in DO or the queue handler?

James•5/4/25, 6:56 PM

If you re-use sessions, where you store the browser instance shouldn't matter much; https://developers.cloudflare.com/browser-rendering/workers-binding-api/reuse-sessions/

Cloudflare Docs

Reuse sessions

The best way to improve the performance of your browser rendering Worker is to reuse sessions. One way to do that is via Durable Objects, which allows you to keep a long running connection from a Worker to a browser. Another way is to keep the browser open after you've finished with it, and connect to that session each time you have a new request.

kaelys.js•5/4/25, 8:48 PM

Thank you, I’ve read all the docs.

I’ll figure it out but what I’m finding is that it’s taking 15s before I get a response back, not sure where the issue is.

1. Basically have an api endpoint inside a DO that takes a url to open in puppeteer (any url has same 15s response time)
2. That gets sent to a queue
3. The queue handler launches puppeteer or connects to an existing session grabs the contents of the page and fetches to DO which resolves the initial api call.

All in one worker, it works fine. Session id is the same across multiple requests but it always takes a minimum of 15s.

The reason I’m using queues as this will grow into crawling our customers sites for compliance and need to test out the viability of using CF for this versus AWS/GCP/appify/etc

dizee•5/5/25, 1:19 AM

Do workers have a way to create new D1 databases? I couldn't find anything in the docs.

S2F STUDIO•5/5/25, 4:41 AM

Is there a webinar on how to deploy to Cloudflare Workers? Or how do one get support

S2F STUDIO•5/5/25, 4:42 AM

Is anyone here an expert on deploying to workers and able to guide for a fee

Ali_fff•5/5/25, 7:16 AM

Hey - So I am new to workers and JS.
By reading the docs, I kinda know how to deploy a React or NextJS app.
But I'm having a hard time to understand how can I deploy a full-stack application with both backend and front-end into one worker.

Can anyone help? Very general guidance could also be a big help
