i'm building an app with vite (react-router) and a wrangler.jsonc, and... man weird stuff happening... i've been trying to deploy with

--env staging

--env staging

--env staging

--env staging, and it wasn't finding my env for some reason. and it turns out, it's because there's this file being written to

.wrangler/deploy/config.json

.wrangler/deploy/config.json

.wrangler/deploy/config.json

.wrangler/deploy/config.json that has these contents:

{"configPath":"../../build/server/wrangler.json","auxiliaryWorkers":[]}%

{"configPath":"../../build/server/wrangler.json","auxiliaryWorkers":[]}%

{"configPath":"../../build/server/wrangler.json","auxiliaryWorkers":[]}%

{"configPath":"../../build/server/wrangler.json","auxiliaryWorkers":[]}%

which points to build/server/wrangler.json being written during the build process, which is a stripped down version of my

Looks like they are supporting JSONC by converting it to JSON, probably just stripping out the comments

zwilyOP•3/18/25, 2:50 AM

that wasn't it... it turns out that the cloudflare vite plugin creates a new flattened wrangler.json, and you have to specify CLOUDFLARE_ENV during the vite build in order for it to build the right one

After upgrading wrangler to 4.1.0 logs have stopped working for me completely. Bug?

Cool, thanks. My workaround of using a script to put it in .dev.vars will live on then lol

Mitya•3/18/25, 4:41 PM

Running Wrangler locally, I'm told that my version is out of date, and that I should run:

npm install --save-dev wrangler@4`

npm install --save-dev wrangler@4`

However this brings the following error:

npm ERR! code EINVALIDTAGNAME
npm ERR! Invalid tag name "4`" of package "wrangler@4`": Tags may not have any characters that encodeURIComponent encodes.

You've got a trailing backtick there.

Mitya•3/18/25, 4:44 PM

Oh god...

Mitya•3/18/25, 4:44 PM

It's one of those days

Mitya•3/18/25, 4:44 PM

Sorry to have wasted your time!

Isaac McFadyen•3/18/25, 4:46 PM

No problem

Mitya•3/18/25, 4:49 PM

One more. Having updated to Wrangler 4, it tells me to change node_compatnode_compat to

nodejs_compat

nodejs_compat

. Should I do this not only in my dev.tomldev.toml but also

wrangler.toml

wrangler.toml

i.e. the TOML for the production version? Does production always use the latest Wrangler?

Mitya•3/18/25, 5:10 PM

I'm not sure what I'm doing wrong here but since updating my (global) Wrangler to @4, my Worker won't run locally. It advises me to add node_compatnode_compat. But a previous message told me to change node_compatnode_compat to

nodejs_compat

nodejs_compat

for use with v.4, which I did. What am I doing wrong?

Mitya•3/18/25, 5:14 PM

I don't have it installed in my project - I just use a global one. Let me see if uninstalling the global Wrangler and installing project-level Wrangler fixes it. But just to be clear, with v4, it should be

nodejs_compat

nodejs_compat

, not node_compatnode_compat, right?

Mitya•3/18/25, 5:16 PM

OK now I have project-level Wrangler 4. When I run the worker it throws a tonne of errors about Node compatibility and tells me to add

nodejs_compat

nodejs_compat

to my config, which is already there.

Mitya•3/18/25, 5:18 PM

Although ironically, at the start of the log output, it says

"Unexpected fields found in top-level field: "nodejs_compat"

So I have messages telling me both to add

nodejs_compat

nodejs_compat

and also that

nodejs_compat

nodejs_compat

is invalid.

Mitya•3/18/25, 5:19 PM

Oh.......

Mitya•3/18/25, 5:21 PM

Thanks, that's fixed it! Really appreciate your help.

Could I just clarify one more thing. Wrangler is a dev dependency. But the config changes I'm making are for both dev and live. So how do I control/do I need to worry about which version of Wrangler runs in production?

MMitya Thanks, that's fixed it! Really appreciate your help. Could I just clarify one ...

Hard@Work•3/18/25, 5:24 PM

Wrangler shouldn't be running in production? Wrangler is used for development/deployment, but once deployed, Wrangler doesn't touch anything

Mitya•3/18/25, 5:29 PM

Right, thanks, I think I thought Wrangler ran everywhere.

Mitya•3/18/25, 5:30 PM

I assumed production used the same environment I had locally, in the same way that developing locally with PHP involves something like Apache, which is also on the live server.

Sort of? Wrangler, under the hood, calls into Miniflare, which runs Workers in

iano•3/19/25, 4:14 PM

Wrangler rewrites the request URL being sent to localhost into the custom domain which is set in wrangler.jsonc. Is that expected? It is very surprising to me?

iano•3/19/25, 4:15 PM

(So for example if I curl http://localhost:8787/ with a console.log in the fetch the fetch sees a request to url custom-domain.com even though its running locally)

jonasb•3/19/25, 8:19 PM

Hey

Now when wrangler@4 generates all the types, does anyone have guidance as to how to build libraries that depend on e.g. D1Database? For https://github.com/jonasb/d1-sql-tag I'm using

@cloudflare/workers-types

@cloudflare/workers-types

, but get incompabilities when e.g. upgrading wrangler
