a worker can indeed be a service binding for itself

I am mostly self taught and unfortunetely dont learn much at work. Can someone help me clear some confusion. In cloudflare workers I often times find myself in situation where the easiest approach would be having a array of 100 objects representing an ecommerce order. Is it a acceptable solution to just iterate through those 100 objects to find the ones that have key === something? Like I always run from that solution because I think looping through each elelment in the array is just a very bad solution. It feels that way atleast

Is a reason that you aren't using an object to look up the ecommerce order?
If you already have the key something like

{
  "key1": {<order info},
  "key2": {<order info},
}

{
  "key1": {<order info},
  "key2": {<order info},
}

{
  "key1": {<order info},
  "key2": {<order info},
}

{
  "key1": {<order info},
  "key2": {<order info},
}

rather then what I believe you are using which is

[
  {"key": 1, <order info>},
  {"key": 2, <order info>}
]

[
  {"key": 1, <order info>},
  {"key": 2, <order info>}
]

[
  {"key": 1, <order info>},
  {"key": 2, <order info>}
]

[
  {"key": 1, <order info>},
  {"key": 2, <order info>}
]

The thing is I’m calling an api that for example gives me all the orders that need to be shipped out today. Then I need to filter through which ones would be for a specific department or something and that’s where I’d loop through the array.

You should use service bindings

I bind it as a service in worker A (

Hyper•7/2/23, 5:46 AM

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?

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

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, 2:57 PM

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

D

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?

D

dave•7/2/23, 9:28 PM

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

cache.delete() a guarantee that the cached item will be gone from the local data center?

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?

H

Hyper•7/3/23, 6:48 AM

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

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

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

.workers.dev

.workers.dev as expected).

D

dave•7/3/23, 9:35 AM

I'm not entirely sure if the

cache.delete(cacheKey)

cache.delete(cacheKey)

cache.delete(cacheKey)

cache.delete(cacheKey) is actually needed, or if

purge_cache

purge_cache

purge_cache

purge_cache will always have cleared the local cache just as fast.

E

Erisa•7/3/23, 9:53 AM

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