Migrate from Wrangler v3 to v4 · Cloudflare Workers docs

Wrangler v4 is a major release focused on updates to underlying systems and dependencies, along with improvements to keep Wrangler commands consistent and clear. Unlike previous major versions of Wrangler, which were foundational rewrites and rearchitectures — Version 4 of Wrangler includes a much smaller set of changes. If you use Wrangler toda...

Hard@Work•3/13/25, 4:51 PM

Basically, it is dynamically generated based on your

wrangler

wrangler

config. So, instead of

@cloudflare/workers-types

@cloudflare/workers-types

having to ship every combination of compatibility dates/compatibility flags, now you can just generate it yourself in one go

Hard@Work•3/13/25, 4:51 PM

Plus of course keeping your binding types in sync

Hard@Work•3/13/25, 4:52 PM

I mean, the team will continue to update

@cloudflare/workers-types

@cloudflare/workers-types

for the forseeable future, so if you don't need it, you don't have to move

Silvan•3/13/25, 4:54 PM

you arent supposed to touch that file anyway. i personally like it very much

Hard@Work•3/13/25, 4:54 PM

Yeah, I like it too, and have been using it for a few months now. But I think it's great that they give you both options

Silvan•3/13/25, 4:55 PM

for sure!

Silvan•3/13/25, 4:56 PM

but yea importing from cf-types/compDate is fine too

Hard@Work•3/13/25, 4:56 PM

I mean, theoretically Workers Types(the Package) is actually larger, it just doesn't count as LoC because it is gitignored

This page over here says the CLOUDFLARE_API_TOKENCLOUDFLARE_API_TOKEN can be used. But if I use the variable then I get an error as ✘ [ERROR] You are logged in with an API Token. Unset the CLOUDFLARE_API_TOKEN in the environment to log in via OAuth.✘ [ERROR] You are logged in with an API Token. Unset the CLOUDFLARE_API_TOKEN in the environment to log in via OAuth.

Okay, now if I try to login with OAuth, the page freezes because the IP was blocked.

The IP was blocked because I was using service like Github Workspace.

Wrangler 4 is a mess and seriously stopping me work with Cloudflare Infrastructure. Can someone have a look and clear the things up?

What is the reason that a person cannot login with API_TOKEN? If you guys are blocking logging in with API_TOKEN, how

wrangler

wrangler

commands are supposed to work in CI environments?

This is seriously a frustruating experience.

What command are you running that is rejecting CLOUDFLARE_API_TOKEN?

and

Wonky Onion•3/13/25, 10:06 PM

You can also just pass in —include-runtime=false and you’ll get just the Env types like before, if you prefer :)

when i try to update my wrangler i get an error thats "unfixable" and so now i cant update my wrangler

Ppenalosa What error are you seeing?

VeriHappy•3/14/25, 2:01 AM

a big text says "▲ [WARNING] The version of Wrangler you are using is now out-of-date.

Please update to the latest version to prevent critical errors.

but when i run npm install --save-dev wrangler@4 i get this

VeriHappy•3/14/25, 2:07 AM

(nvm i fixed it)

VeriHappy•3/14/25, 2:07 AM

i did npm update -g wranglernpm update -g wrangler

Ppenalosa To clarify, were these commands working with Wrangler v3?

ashutosh•3/14/25, 5:34 AM

I started getting this error about 1 or 2 week ago. I assumed that it was due to updated version or wrangler but now when I tried it with lower version of wrangler (i.e. 3.93.03.93.0), I am still getting the same error which probably means there was some change in the Cloudflare APIs which is causing this issue.

ashutosh•3/14/25, 5:37 AM

Getting this error with all the versions of wrangler (probably) while logging in with OAuth.

With wrangler v4, do we still ned to set "types": ["./worker-configuration.d.ts"]"types": ["./worker-configuration.d.ts"] in the tsconfig?

VeriHappy•3/14/25, 9:11 AM

Ye I fixed it

VeriHappy•3/14/25, 9:12 AM

And I was using v3

kian•3/14/25, 12:47 PM

It "just works" in Wrangler 4, but your IDE has no knowledge of what Wrangler supports anyhow.

That just sounds like you need to update the TypeScript version or compilerOptions.targetcompilerOptions.target in tsconfig?

James•3/14/25, 2:52 PM

It's possible rulesrules aren't being applied to dynamic imports. Out of interest, does it work if you just import html from '../templates/foo.html'import html from '../templates/foo.html' at the top of the file?

Franco Romano Losada•3/14/25, 3:13 PM

Hey everyone, do you know if child_process support via unenv will be implemented? https://github.com/unjs/unenv?tab=readme-ov-file#:~:text=%E2%9C%85%20node%3Achild_process

According to the unenv repo its already supported but I have an issue with a dependency in a worker.

It says:

✘ [ERROR] Error in transcribeVideo: Error: [unenv] child_process.spawn is not
implemented yet!

Althaf•3/14/25, 3:23 PM

Hey like i have hosted my vite react app in cloudflare pages and honobackend in the cf workers and there is an issue like when i login the cookie is not present i chrome cookies but in request header it is availabe and also like when i try to logout the cookie is still on the request header and unable to logout on dev no issues. after some reserch i have found like if the front end and backend have different domains like "pages.dev" and "worker.dev" as browser will not save cookie . so is there is a fix for it like without custom domain on dev side the vite proxy works but on production it will not any fix for it

KKeebs btw it’s not very obvious that those are two paths and not two steps of one path

flashblaze•3/14/25, 3:39 PM

ah, got what you meant. will try to clarify that you can do either of the steps

Franco Romano Losada•3/14/25, 8:51 PM

@Skye thanks, I misread the table. I thought that it was one of the implemented APIs, not a mock-up.

Farhian•3/15/25, 12:10 AM

Hi guys, starting a few days ago, our CI pipeline publishing a worker started failing with this error. Any ideas why that might be? Thank you!

Farhian•3/15/25, 5:06 AM

Thank you @penalosa

EXtremeExploit•3/15/25, 3:15 PM

is there a way or workaround for npm being annoying about audit vulns for wrangler? or do i have to wait for wrangler to update to fix them?

VVeriHappy i did `npm update -g wrangler`

Isaac McFadyen•3/15/25, 3:27 PM

@EXtremeExploit this user fixed it by running an update (seemingly NPM was caching old deps), try that?

EXtremeExploit•3/15/25, 4:06 PM

i did try this already, the versions wrangler depends on esbuild and cookie have the vulns, and i want to use overrides as less as possible, its not a big deal so i guess i will just wait

dan•3/15/25, 5:58 PM

I can't seem to get the new process.env flag to work...I have this in my wrangler config:

"compatibility_date": "2025-02-28",
"compatibility_flags": [
    "nodejs_compat",
    "nodejs_compat_populate_process_env"
],

"compatibility_date": "2025-02-28",
"compatibility_flags": [
    "nodejs_compat",
    "nodejs_compat_populate_process_env"
],

    console.log('process.env', process.env);
    console.log(agent.env.OPENAI_API_KEY);

    console.log('process.env', process.env);
    console.log(agent.env.OPENAI_API_KEY);

Is there any migration guide?
