nvm so I can wrangler dev, can I wrangler preview?

I am trying to preview so like, my local build is fine, and when I run wrangler dev it is fine, but when I go to my site, there's an error

ZZachHandley nvm so I can wrangler dev, can I wrangler preview?

IIRC they got rid of wrangler previewwrangler preview?

ZachHandleyOP•11/5/25, 11:13 PM

one complaint I have is that it's SO hard to find these weird errors that occasionally happen, even with observability

ZachHandleyOP•11/5/25, 11:13 PM

when the workers build has an error that dev doesn't

ALECKS•11/6/25, 2:17 AM

Man, for all the things I love about Cloudflare, I keep running into some very painful friction points.

Cannot access "WSTenantRouter#publish" as Durable Object RPC is not yet supported between multiple dev sessions.

... so frustrating.

What are we supposed to do for intra worker/DO messaging? Queues don't work when using multiple dev commands (which you have to do when using Vite). Now I see that DO's can't make RPC calls across dev sessions? Workers can, why can't DOs?

--edit: Looks like .fetch() works from DO to worker in another dev session

is something wrong with workers?

is it possible to configure builds through the wrangler config file?

Checking before I go to -help -- is there a pattern for preserving old assets or implementing "skew protection" on CF Workers + Static Assets that I'm missing? It doesn't seem like there's any complete solution for this on the current version of Workers that I can find.

Context: we're running into the issue where we frequently deploy an SPA to Workers with Static Assets and users who are on stale versions of the app encounter 404s when assets lazy-load and it breaks the app., The assets have a fingerprint in them (produced by Vite) and it changes between deploys. The old assets / fingerprints are immediately invalidated on deploy (AFAICT.) This is a pure SPA that doesn't use SSR at all, there is a Workers script that proxies our API that is invoked when no asset matches; it passes API paths to the backend API service and otherwise just fetches from env.ASSETSenv.ASSETS.

I've seen this, but our session IDs are actually persistent across full page reloads, so it seems like users would get "stuck" on an old version until their session recycled (which could be a long time in this case) and the other solutions I can think of to key the affinity (e.g. set a cookie with a nonce on initial document load) I think would break when there's multiple tabs / etc.

Hi , I am Vijayabaskar from India, I am building a TANCN (OSS Project), I have my application deployed on Cloudflare, I have also purchased a domain tancn.dev from the cloudflare itslef, I love cloudfare and wrangler in general ,

Now I have a issue which is been bugging me lately, that is my site tancn.dev is randomly throwing 500 error or This Site Can't be reached error from the user

Here is a issue from one of my users : https://github.com/Vijayabaskar56/tancn/issues/30 , and I am not sure that is affecting certain region or affecting randomly , there is no error reported on the dashboard or misconfigured domain

here is some other user also reporting

Hi, I am currently trying to migrate one of my Cloudflare Pages Nuxt (+ Nitro backend) applications to Cloudflare workers but I can't find the equivalent for the environment seperation (prod vars vs preview vars). I looked a bit around in the configuration and found a documentation that looked promising but is putting secrets into my Cloudflare Workers environment really only possible through the Wrangler CLI as described in this documentation? https://developers.cloudflare.com/workers/wrangler/environments/#_top

Until now I have just deployed through the Git integration and haven't really looked into the Cloudflare CLI tools since it worked out for my 10+ Pages Nuxt apps perfectly (i dont even know if Pages has an equivalent for that)

Any tips or guidance would be much appreciated, thank you very much (ui-way to add secrets for specific envs? only possible through the cli?)

texan•11/7/25, 7:56 PM

it’s not you, it’s us.

Environments have been a huge topic of discussion. There’s lot of info in discord if you search around in help threads.

I would suggest getting started by configuring workers environments and WCI. From there, many help threads discussing how to configure the environments with WCI. We might need a full walk through in our docs about how to set this up fully though

nico•11/7/25, 8:08 PM

Ahh alright, good to know, at least I’m not just blind then

Is this separation planned to be visible / configurable in the frontend (Workers UI) at some point? Just wondering if it’s worth waiting a few months before migrating, or if there’s no information on that yet.

WCI is not a common term for me, does that basically just mean to integrate this Worker CLI (it is called wrangler i guess) into my CI (GitHub Actions in my case)?

Thanks again for the super quick reply, that already helps a lot

texan•11/7/25, 8:10 PM

Ah, that’s shorthand for Workers CI (builds). There were some echos on making this experience better via dash.

Wrangler environments is a way to configure multiple workers with separate bindings, using the same underlying codebase. You can use this concept to create a production worker and staging worker. They’d be separate workers, but you can definitely set up workers CI to automatically upload, deploy, etc to those environments based on branch

Sweet. Yea I asked there before. Basically I'm running into this issue (out of nowhere) where some API requests on my NextJS backend are returning this Cloudflare error:

For context, I'm trying to access my MongoDB collection; however it seems to also happen with other API calls as well. I don't really know where it's come from, it started out of nowhere and the documentation isn't super helpful.

Dubz•11/8/25, 8:54 AM

So I have a genuine question. I know that workers are limited to 100k executions per day (on the free plan), and this is shared amongst all account workers, not per-worker. However, there's not really anything preventing users from just making another Cloudflare account to get another 100k executions. Obviously there will be limitations as data can't be shared easily, but if you're making multiple, unrelated projects, that wouldn't matter. Even if a domain is needed on your account, you can get super cheap ones for like $4/yr (which is less than one month of pro plan). Has this ever been considered and thought to change? It'd be cool if we could create "projects" where they have clusters of various services and each of those have their own pool of usage (although I hope that doesn't change them to lower thresholds, in which case forget this entire message lol).

If there are legitimate separate purposes though then not entirely. Companies segregate parts of their business under different names for many reasons. That would be separate entities then so not really applicable, and they could realistically spread put whatever they're trying to do with that. Of course there's probably gonna be some person to take things to the extreme with like 50+ accounts just to abuse it and ruin it for everyone else. I only separate mine for business/personal stuff because separation of access is just good practice.

Borna Punda•11/8/25, 1:06 PM

Hey, so per-branch/commit previews sound great, but I see one major drawback. Couldn't someone just make a commit that dumps all the environment secrets and use that exfiltrate them? Now, I know only trusted people should have push access, but that is still a privilege escalation.

Borna Punda•11/8/25, 1:06 PM

Or do previews not get access to production secrets?
