I'm trying to use cloudflare tunnels to forward traffic to a localhost wrangler project. Works fine.

What doesn't seem to work is the request received by wrangler doesn't include the host header as defined in the tunnel config. Any solution?

Cyb3r-Jak3•9/17/24, 11:51 PM

Try setting the HTTP Host Header option for the tunnel. It will be under the public hostname

kaelys.jsOP•9/17/24, 11:53 PM

Yes, it is set. If I load the tunnel direct in chrome I can see the headers in the response (including custom headers defined via rules).

But when logging the request object received by wrangler, none of those headers are present

Payello•9/19/24, 11:50 AM

Either:

run
```
wrangler dev
```
```
wrangler dev
```
for both worker projects or
include the second worker as a new WorkerEntrypoint in the same project (see demo project)

I am using "wrangler pages dev" for building a simple Pages site (static html). I am getting errors from my browser due to the css file being served back with Content-Type: text/html instead of text/css. I see a few similar issues from 1-2 years ago, but not many, and no fixes. I also don't think I've had this issue with previous Pages developments. Any suggestions?

JacobMGEvans•9/20/24, 2:32 AM

So besides the running multiple workers with Wrangler, the communicating between Workers can be done with Service bindings https://developers.cloudflare.com/workers/wrangler/configuration/#service-bindings

hey there, just wanted to ask if there was an eta on dynamic bindings? i would really like to use them for this one project because they would make my life just so much easier

kaelys.jsOP•9/23/24, 11:51 PM

Is there anyway to get wrangler to work with localhost self signed certificates. This is a common issue with wrangler that has had no resolution since wrangler 3 was released. It's only a problem with wrangler.

Hello!

Having an issue trying to set up routes in wrangler.toml

I want to set both the custom domain and also the wildcard routes but I can't

Example of what I'm seeking:

# wrangler.toml
[env.production]
vars = { ENVIRONMENT = "production" }
routes = [
  { pattern = "sub.mysite.io/*", zone_name = "mysite.io" },
  { pattern = "sub.mysite.io", zone_name = "mysite.io", custom_domain = true },
]

# wrangler.toml
[env.production]
vars = { ENVIRONMENT = "production" }
routes = [
  { pattern = "sub.mysite.io/*", zone_name = "mysite.io" },
  { pattern = "sub.mysite.io", zone_name = "mysite.io", custom_domain = true },
]

What is the correct syntax ? The documentation doesn't mention both use cases together (custom domain and wildcard on subdomains); but the only way is to manually edit on the dashboard it seems ?

akashra•9/25/24, 1:31 AM

Can a D1 binding be set up in a wrangler.toml file to take a local value for the

database_id

database_id

for pages development from .preview.vars.preview.vars and in the prod environment from a secret? The docs don't make it particularly clear if or how I might do that - or even how to use vars to be referenced with wrangler.toml

kian•9/25/24, 2:02 AM

Nope, but IDs aren't secrets anyways.

Kkian Nope, but IDs aren't secrets anyways.

akashra•9/25/24, 5:03 AM

Okay, so there's no harm in the UUID of a prod DB being exposed in a repo - since it would presumably require credentials to even find out anything about it?

kian•9/25/24, 5:04 AM

Yep

akashra•9/25/24, 5:06 AM

ok, ta.

Hello, I’m Allie!•9/28/24, 9:41 PM

All of your wrangler config is safe to make public, as long as you do your dilingence with not putting secrets in it(as you noted)

thank you for the confirmation!

I'm using wrangler+static assets+remix (classic compiler mode), and am running into this problem:

I edit a file
remix compiler rebuilds, and places new files into public/buildpublic/build
wrangler then does a reload for each new/updated file in public/buildpublic/build, so it takes a long time and my window is full of this:

Anyone know what's going on here? I pushed a sample app to https://github.com/zwily/remix-wrangler-much-restarting with the config. You just

npm run dev

npm run dev

and then edit app/routes/_index.tsxapp/routes/_index.tsx to see all the restarting action.

I'm trying to understand if there are any breaking changes between wrangler versions. Is there an easy way to do that? I'm trying to upgrade from 3.57.0 to latest, but want to confirm that this would be safe. Any help/ideas?

joshka•10/1/24, 3:14 PM

Feature request (not sure if this is the right place for this):

It would be nice if building rust using the workers build just worked (instead of having to install rust manually)
It would be also be convenient (time saving of minutes) if the build supported some form of build caching for rust builds

Without these two features it's better to use GitHub CI instead of Cloudflare Build to deploy

I'm encountering a weird issue, I got a monorepo repo structure that looks like this

.github
  └─ workflows
apps
  ├─ accounts
  ├─ web
  └─ api
packages
  ├─ auth
  ├─ db
  └─ ui

.github
  └─ workflows
apps
  ├─ accounts
  ├─ web
  └─ api
packages
  ├─ auth
  ├─ db
  └─ ui

you see the apps and some packages need each other to function and also it's designed that kv, d1, r2.. etc is remote, but since the miniflare instance/ .wrangler is made in each project separately it breaks the whole functionality in local development, how can I make all apps use the same .wrangler/miniflare instace instead of creating one separately each time

This would be a tool that I'd make sure to include in my stack. Currently, I'm containerising projects/accounts.

You could probably make some tool to swap out

The recommendation is to use a framework that supports bindings in dev mode

richtera•10/3/24, 11:45 AM

I am still struggling with api keys not supporting lockdown to either a specific worker or pages project as well as production and preview. Is this going to be fixed? It feels like I have asked several times and it seemed other people needed it as well. I am currently unable to invite other developers to help with workers or pages projects unless I use github ci, but when using github ci, it's kind of dangerous as well; if someone decides to change the github action to deploy on a different cloudflare project they can easily overwrite or deploy things they should not, especially on preview branches.

I'm trying to login through cli using
npx wrangler login
. It opens a link in browser and asks for permission on the cloudfare page, then it opens a localhost page which doesn't load and says localhost refused to connect. CLI displays the error:
Error: ENOENT: no such file or directory, open 'C:\Users\hp\AppData\Roaming\xdg.config.wrangler\config\default.toml'

}

I then manually created default.toml in the mentioned path. I tried to login after this, then the issue was:
