In local dev mode with wrangler, is there a way to run a worker and a durable object.

worker is the main site
durable is a websocket server under /path
This setup works find in production, where I can use worker routes. Is there something similar for local dev? (so it looks like both are under localhost:3000 and I can dev like I prod?

Not entirely sure I understand what you mean? You can just have the Worker forward requests on

/path

/path

to your DO?

I am on v3.109.1 and whenever I try to deploy with wrangler deploy, getting this error:

You are logged in with an API Token. Unset the CLOUDFLARE_API_TOKEN in the environment to log in via OAuth.

Why can't I deploy with CLOUDFLARE_API_TOKEN ? It used to work fine with older version!

Oh, you meant a DO within one Worker and a separate Worker, on the same port?

I don’t think you can do that now. Maybe make an issue on

Is it possible to connect two workers on localhost through the binding mechanisms? (This subpath stuff is going away eventually, can move that work forward)

I recall (maybe) that it was not supported yet, but I was a bit early in my journey to hang the details on prior experience. For now, for the feature I'm working on, http fetch is going to be fine, just have to make the websocket host configurable for dev vs prod.

Actually, I did want the websocket worker to share the D1 & KV with the webapp worker. Is this possible in prod & local dev? (prod seems like an easy yes? while dev seems like it may be an issue because they are in different dirs and running in different wrangler setups?

Is there a way to support using wrangler with multiple accounts locally, so I don't have to oauth as a switch between projects I need to deploy?

(hoping that there is a similar answer to @custom's question, i.e. something like an API Key)

I suspect it is a bug in wrangler.
I always get EOF with functions for local environment.
d1-database

When using the wrangler dev command, the server does not start and an EOF error occurs.

ぷとん(Puton)•2/18/25, 8:43 AM

Hono also get EOF for the dev command, but the deploy command is possible and works fine when checked in the browser after deployment.

Hi ! My company have an access to all the CF account of our clients. We have some bash scripts to do some tasks like "npx wrangler deploy". When we create a new project, without yet the node_modules/.mf/ directory, the CLI wrangler will ask us on which account to upload it.

The problem is it's not works inside a bash script ( SystemError [ERR_TTY_INIT_FAILED]: TTY initialization failed: uv_tty_init returned EINVAL )

I've search in the command parameters, I haven't found one to explicit choose the client account. May be there another solution ?

This is the ID of the account associated with your zone. You might have more than one account, so make sure to use the ID of the account associated with the zone/route you provide, if you provide one. It can also be specified through the

Ben-xD•2/23/25, 4:07 PM

Why is wrangler.jsonc now supported, and seemingly the default option (docs default to this, and this file gets generated)? For an app i work on, I added support for yaml files instead of just json/jsonc (for backwards compatibility) and recommend everyone to use yaml because it minimises special characters (

{}

{}

).

I'm just curious. I tried to search for it and check the PR but didn't find an answer. Probably just some slight familiarity for most developers knowing json already? Or maybe it pairs up with Json Schema a bit better.

Hello, I’m Allie!•2/23/25, 11:42 PM

One, as you pointed out, is JSON schemas. While there is a way to validate TOML with a schema, I don’t think it is an official standard. In addition, quite a few people had issues with TOML inheritance, and being that most Workers are written in JS, most devs building on Workers are more familiar with JSON

Though note above is a best guess, as I am not on the Developer Productivity Team, which oversees wrangler, and would know what the official reasoning is

rolito•2/24/25, 2:12 PM

Hi guys, i'm new using wrangler and the cloudflare ecosystem. I want to know if there is a straightforward (non-manual) way to retrieve and update the IDs of resource bindings associated with another Cloudflare account in the wrangler config?
I mean, when i clone a repo with a wrangler config, and I want to deploy it in my account, i always must create and change manually the ids of resources?

verdverm.comOP•2/24/25, 2:44 PM

CUE is the way :] schemas + config in a single language

JSONC is just another hack on a data format when what we really want is a proper config language

beelzabub•2/24/25, 6:44 PM

Does wrangler need some kind of special flags to print stderr normally when stderr is a pipe? I'm not seeing any of the console.debug messages unless I spawn wrangler with stderr set to inherit. I've tried --log-level but that seems to be the workerd log level.

dandoen•2/25/25, 4:39 PM

hi team, i'm not exactly sure how to best debug this, but very sporadically i'm seeing the consent dialog. initially i thought this was only a localhost thing, but now i'm also seeing it on my production environment. is there any way i can figure out why the hell the consent dialog shows up? i suspect it's related to using either using Workflows or Vectorize as i have binding to both and every time a code path gets triggered that hits either of those two I notice this. i'm not interacting with ANY thing unusual. i'm calling .create for Workflows for ex.. it's as if i'm doing wrangler login for the first time
