awesome, thank you!

If worker B is a web framework (

Hono

Hono

) and I usually interact with it by calling it with

https://worker_b.me.workers.dev/${param}

https://worker_b.me.workers.dev/${param}

I bind it as a service in worker A (

env.B

env.B

), how do I call it and pass

param

param

const result = await env.B.fetch(param)
const json = await result.json()

const result = await env.B.fetch(param)
const json = await result.json()

const result = await env.B.fetch(param)
const json = await result.json()

const result = await env.B.fetch(param)
const json = await result.json()

Hey guys. We have been looking at workers for a while and have been interested in migrating our backend to workers. I have a couple concerns though which I needed some guidance with. For starters, our backend right now is a complex express app with many routes, middleware, controllers etc. I have looked at Hono and have liked what they have to offer, so im sure we'll be fine in terms of refactoring our app to use Hono instead of express. My main concern though is that we use libraries such as @sendgrid/mail, @aws-sdk/client-s3, mongoose, speakeasy, sharp, multer-s3, firebase-admin, just to name a few. I'm aware that workers doesnt support a full node.js environment yet. Do you guys think it will be possible to migrate to workers?

Hello, I’m Allie!•7/2/23, 5:54 AM

It definitely won’t be a one-click migration(and some of the libraries may have to be rewritten from scratch), but I don’t see anything that would prevent it at the moment

sathoro•7/2/23, 9:53 AM

dave•7/2/23, 2:45 PM

It’s 100% working for me with the invalid domain. Could you try using a custom cache key?

dave•7/2/23, 2:48 PM

I’ll check again to see if I’m overlooking something.

dave•7/2/23, 2:55 PM

I’m using with a period.

async function createCacheUrl(path: string, safe_formdata: FormData): Promise<URL> {
    const byter = await getFormHash(safe_formdata);

    const cacheUrl = new URL('https://ai.moda.invalid');

    cacheUrl.pathname = path + '/' + byter;

    return cacheUrl;
}

async function createCacheUrl(path: string, safe_formdata: FormData): Promise<URL> {
    const byter = await getFormHash(safe_formdata);

    const cacheUrl = new URL('https://ai.moda.invalid');

    cacheUrl.pathname = path + '/' + byter;

    return cacheUrl;
}

dave•7/2/23, 2:56 PM

Ah I see I already shared this, my bad.

dave•7/2/23, 2:57 PM

That sorta makes sense, wouldn’t be surprised if there’s some very light URL validation being done before caching a URL.

dave•7/2/23, 3:57 PM

@lekensteyn have you looked into how purging the Cache API globally (for a single URL) works with a fake domain name?

dave•7/2/23, 9:28 PM

Is the Cache API shared among all Workers in a zone?

Erisa•7/2/23, 9:44 PM

yes

dave•7/2/23, 9:51 PM

ooo thank you, was about to hit myself in the face with that one

docy•7/3/23, 12:40 AM

thoughts on itty vs hono? hono claims to be 2x faster

Unsmart•7/3/23, 12:42 AM

Most people here use hono afaik but both are good and will probably be exactly the same performance wise on workers

docy•7/3/23, 12:43 AM

thanks

EErisa yes

dave•7/3/23, 3:38 AM

is awaiting on

cache.delete()

cache.delete()

a guarantee that the cached item will be gone from the local data center?

Unsmart•7/3/23, 3:39 AM

Pretty sure it will throw if it fails so yes

Kkian There isn't in Miniflare 3, yet

Shirokawa•7/3/23, 5:45 AM

Thanks a lot! What is the relationship between miniflare and Wrangler by the way? Being new to Cloudflare Workers this has been somewhat confusing to me.

Hyper•7/3/23, 6:47 AM

Hey all. What would be the best way to initialize connections to external services, i.e in my example to MongoDB, when using Hono with workers? Right now, the only way ive been able to do it (using the module worker mode) is by creating custom middleware that initializes a realm app, logs in, and connects to the DB before every request that needs to interact with the DB. Idk how practical this approach is though. Any ideas?

Hyper•7/3/23, 6:48 AM

Ideally, I would like to connect to the database once and then listen for requests

Shirokawa•7/3/23, 7:50 AM

Cool! Thanks a lot for the clarification!:)

EErisa yes

dave•7/3/23, 9:22 AM

@lekensteyn thank you both for your advice, here's what I got working to purge the Worker cache both locally and globally for a URL.

https://gist.github.com/Manouchehri/8db5ebcecbbc6b286ef226cb57122b1d

I'm using

https://ai.moda.invalid/hash_here

https://ai.moda.invalid/hash_here

as my URL, I can confirm it's working (only when using a custom domain though afaik, not

.workers.dev

.workers.dev

as expected).

dave•7/3/23, 9:35 AM

I'm not entirely sure if the

cache.delete(cacheKey)

cache.delete(cacheKey)

is actually needed, or if

purge_cache

purge_cache

will always have cleared the local cache just as fast.

Erisa•7/3/23, 9:53 AM

It wouldnt be immediate, the global cache purge can take a number of seconds to go through

divby0•7/3/23, 10:04 AM

I have a worker that reverse-proxies a blog on a subdirectory. It works perfect on the worker preview url, but it redirects to the origin blog instead of proxying it when I use my custom domain.

I am very sure I am just missing a little detail on how workers work.

divby0•7/3/23, 10:04 AM

I have the worker code and detailed explanation in the #workers-help (currently the topmost question) if that's needed

Ashley•7/3/23, 10:58 AM

To deploy a worker using Terraform, is the only module that works https://registry.terraform.io/providers/cloudflare/cloudflare/latest/docs/resources/worker_script?

I'm asking as script seems a bit... misleading / odd, as modern workers often have several files, not just one "script". Anything else in TF modules doesn't look suitable though, so am I missing something, or is it just not possible with TF and we have to use Wrangler, for example?

Hey I am not able to "create service" button like this

NaveenSingh900•7/3/23, 11:05 AM

Whenever I click on mange worker I got this page plz help me

Screenshot_2023-07-03-16-35-03-675_com.android.chrome.jpg

Erisa•7/3/23, 11:20 AM

The dashboard has been changed around since that tutorial was made, click "Create Worker" on the page you end up on and you should be on the right track

Erisa•7/3/23, 11:22 AM

@NaveenSingh900

NaveenSingh900•7/3/23, 11:23 AM

It creates service and creates worker is same?

Erisa•7/3/23, 11:25 AM

Yes

CCarsonPoole do I need to see some sort of field and `switch` between the names or something?

kian•7/3/23, 6:57 PM

Yep

Rockmeister•7/3/23, 7:39 PM

When I log into my account and click worker routes, the manager workers button is disabled. Is that because I don’t have permission to manage or create workers?

I’ve installed the wrangler CLI locally and tried to deploy a worker, which led to a 10000 auth error. But I show as having write permission with wrangler whoami. Am I missing something?

docy•7/3/23, 7:46 PM

is there a wrangler command to delete/reset the local kv database? can't find anything in the docs

docy•7/3/23, 7:47 PM

or can i just rm -rf .wranglerrm -rf .wrangler

kian•7/3/23, 8:34 PM

You have a single Consumer Worker which handles multiple queues - so just repeat the [[queues.consumers]][[queues.consumers]] block
