Chaika•8/8/24, 1:41 PM

way different in prod vs local

Chaika•8/8/24, 1:41 PM

Prod your D1 DB is a Single Threaded Durable Object, in dev it's just sqlite and an sqlite file

Chaika•8/8/24, 1:43 PM

You can specify

--persist-to

--persist-to

in the dev command https://developers.cloudflare.com/workers/testing/local-development/#work-with-local-data, https://developers.cloudflare.com/workers/wrangler/commands/#dev to specify a specific folder to persist stuff too, while I think sqlite itself would be fine idk if the rest of it would if you're talking about running it at the same time

detectiveConan•8/8/24, 1:44 PM

hey @Chaika dude can you help me out as I am trying to add security headers to my website. but I tried to add them via nagivating to rules>transform rules>modify response header and adding it but still not reflecting on checked by securityheaders?

Chaika•8/8/24, 1:44 PM

doesn't sound related to workers, make a #general-help thread including the rule you made and your website url?

iskaOP•8/8/24, 1:46 PM

yes but the thing is by default each worker create its own local state .wrangler where the sql file is set, so each worker pointing to another db , and I would want them to share it , is there a way to do so ?

detectiveConan•8/8/24, 1:46 PM

even I tried with deploying workers but that also not help. shall I share my script here and you can check wether it's correct or not?

Chaika•8/8/24, 1:47 PM

you don't need a worker, would be a waste of requests/paying if you just want to add headers, stick with transform rules

Chaika•8/8/24, 1:47 PM

the --persist-to flag can be used to override where that local state folder is

iskaOP•8/8/24, 1:47 PM

Persist to was what I was looking for

iskaOP•8/8/24, 1:47 PM

Exactly

iskaOP•8/8/24, 1:47 PM

Thanks

iskaOP•8/8/24, 1:47 PM

do I have to do something to avoid lock issue using that ?

ArmoredCavalry•8/8/24, 3:13 PM

Not sure if ok to cross-post my help request here, but if so - 'Global' Worker for Logging (alternative for logflare App)

delta•8/8/24, 6:21 PM

Is it common for worker to take some time (e.g., 1 second for a 100 MiB transfer) to complete a PUT operation to the R2 storage after the user has sent the entire request body?

rawwerks•8/8/24, 6:38 PM

I'm following along here : https://developers.cloudflare.com/workers-ai/configuration/open-ai-compatibility/, with one question:
do i need to set node_compat = truenode_compat = true (in my

wrangler.toml

wrangler.toml

) in order to use the openai node/TS SDK? (import OpenAI from "openai";import OpenAI from "openai";)

iskaOP•8/8/24, 7:42 PM

someone could share me a good flow of production grade ci/cd for workers apps and services ?

will take anything example, blog, tuto

like what's the idea ?

run tests
deploy in preview
then add on demand deploy to prod
?

not sure what should i do more for workers usually with regular services you have lot of steps involving bundling and optimizations like docker, kubernetes yada yada but this part seems to be taken care of automatically

AArma Basically "cloudflare-internal:email" does not work on miniflare (yet)

Is there a way to avoid it from breaking local dev?

Hello, I’m Allie!•8/8/24, 7:53 PM

Don’t import it in local

Hello, I’m Allie!•8/8/24, 7:53 PM

We have an issue up for it

Hello, I’m Allie!•8/8/24, 7:53 PM

Not ideal

HHello, I’m Allie!Don’t import it in local

dave•8/8/24, 7:53 PM

you can do that?

Ddave you can do that?

Hello, I’m Allie!•8/8/24, 7:53 PM

Sorry, I meant just completely disable email paths in local dev

Hello, I’m Allie!•8/8/24, 7:53 PM

I’m not sure I’m wording correctly

Hello, I’m Allie!•8/8/24, 7:54 PM

But if nothing else, dynamic import should

work

Assuming that you aren’t running anything else, no

kunal•8/9/24, 12:57 AM

For folks using Hyperdrive: Do you create a connection globally (outside the bounds of a request) so it's reused for the worker lifetime, or are you creating a connection per-request? Any performance implications for doing one or the other?

Normally I would do the former, but all the docs suggest the latter, so not sure if there is something Hyperdrive specific to keep in mind

Kkunal For folks using Hyperdrive: Do you create a connection globally (outside the bou...

Isaac McFadyen•8/9/24, 1:20 AM

Hyperdrive keeps a connection pool warm outside of your Worker (kinda like PgBouncer) so that's why globally storing the connection isn't required.

Isaac McFadyen•8/9/24, 1:21 AM

Globally storing anything in Workers can cause issues when dealing with multiple requests happening at the same time, so if there's no real specific reason to (which there isn't with Hyperdrive) it's best just to reconnect.

CChaika the --persist-to flag can be used to override where that local state folder is

ItsWendell•8/9/24, 7:04 AM

This actually has been working fine for us for local development, though we rarely have actual concurrent writes locally but it works fine for KV / R2 / D1 and stuff.

iskaOP•8/9/24, 9:03 AM

thanks god this flag exist , very much needed for local indeed

iskaOP•8/9/24, 9:04 AM

one thing though that was not practical is the hash of the sqlite file in local state i had to dig deep in a github issue to understand i had to decode it

Iiska thanks god this flag exist , very much needed for local indeed

ItsWendell•8/9/24, 9:30 AM

This is more a nextjs thing than a next on pages thing fyi!

ItsWendell•8/9/24, 9:31 AM

Not sure what you mean here, can you elaborate?

Jose Ramos•8/9/24, 3:18 PM

My structure looks like this
src/index.js
src/router/routes.js

index.js
addEventListener('fetch', (event) => {
event.respondWith(router.handle(event.request))
});

routes has:

import { Router } from 'itty-router';

// Create a new router
const router = Router()

/*
Our index route, a simple hello world.
/
router.get("/", () => {
return new Response("Hello, world! This is the root page of your Worker template.")
})

router.all("", () => new Response("404, not found!", { status: 404 }));

export default router;

everytime I execute dev i get [wrangler:inf] GET / 500 Internal Server Error (48ms)
[wrangler:inf] GET /favicon.ico 500 Internal Server Error (2ms)
A hanging Promise was canceled. This happens when the worker runtime is waiting for a Promise from JavaScript to resolve, but has detected that the Promise cannot possibly ever resolve because all code and events related to the Promise's I/O context have already finished.
X [ERROR] Uncaught (in response) Error: The script will never generate a response.

Odd question is there support for mono repos?

Jjustaname Odd question is there support for mono repos?

Hello, I’m Allie!•8/9/24, 11:05 PM

In Workers?

wrangler

wrangler

doesn’t care about the layout of your project, you just run it in the directory you want to interact with

justaname•8/9/24, 11:05 PM

Alright thank you for the quick response! Thought so just wanted to be sure

tbehrsin•8/10/24, 7:39 AM

Hey... I have an issue adding a new website to my free plan. It says I have unpaid invoices, which I don't. The issue has been ongoing for over a month waiting for support to respond. Ticket number #01007138.

tbehrsin•8/10/24, 7:42 AM

The error happens when selecting the free plan and it says "You cannot add or modify subscriptions or services until all invoices are paid. Download each "Unpaid" invoice on your Billing page and click the "Pay online" link within each invoice to fix your account (Code: 1323)". However on the Billing Page it lists all invoices as having been paid.
