Otherwise, Durable Objects are the only thing that CF had that is really meant for strongly consistent counting

It indeed does help, I am just worried because it is on beta and no pricing is available

Ian•5/21/23, 11:51 AM

Thanks tho

That's very understandable. There was some discussion in that channel about how pricing might work but AFAIK nothing is firm on that yet

i am not sure if I should bet on it tbh, if such a product exists for the purpose of usage-based-billing (this is what says in the docs for one of the usages apparently), it should have a much lower price if we compare it to existing storage options thonk

Any reason why when upgrading to Wrangler 3 and using the latest

compatibility_date

compatibility_date

why creating new Request objects would result in an empty object? Using module syntax, trying to create any new requests from within a module results in

{}

{}

when outputting it to console even with

console.log(JSON.stringify(req))

console.log(JSON.stringify(req))

... bit stumped as this was working just fine before I tried migrating things to Wrangler v3 and updated my

compatibility_date

compatibility_date

... any ideas?

This is being done to create new Requests with custom cookies attached to pull information from an external website.

Murder Chicken•5/21/23, 5:26 PM

Any easy way to inspect the Request object created? Suddenly, this block of code (where

requests

requests

is an array of Request objects)...

const responseData = await Promise.all(requests.map(request => fetch(request).then(r => r.json())))

const responseData = await Promise.all(requests.map(request => fetch(request).then(r => r.json())))

... no longer works resulting in this error...

Cannot read properties of undefined (reading 'map')
TypeError: Cannot read properties of undefined (reading 'forEach')

Cannot read properties of undefined (reading 'map')
TypeError: Cannot read properties of undefined (reading 'forEach')

Which has me baffled... trying to figure out where it's failing.

Is it possible to trigger a worker

scheduledEvent

scheduledEvent

from a development environment similar to the

--test-scheduled

--test-scheduled

flag and hitting the

__scheduled

__scheduled

route locally?

J

James•5/21/23, 6:36 PM

In dev, miniflare used to support hitting

/cdn-cgi/mf/scheduled

/cdn-cgi/mf/scheduled

but I don't believe that's a thing anymore with v3 unfortunately.

D

DaniFoldi•5/21/23, 6:38 PM

it'll be reimplemented in v3 soon

M

Murder Chicken•5/21/23, 7:02 PM

locally in v3, it works fine, just add the

--test-scheduled

--test-scheduled

flag and hit the

__scheduled

__scheduled

route at the root of the domain. but once it's pushed to a development environment in CF, you have to wait for the event to trigger so I was hoping we could somehow trigger it manually.

with the new TCP connections thing, i'm wondering if it would make sense to keep a postgres connection alive in a durable object as to not have to spin a new one for every worker run?

Hi folks, I bought a domain name from cloudflare this month, and use pages to host my web site, it's awseome!

I'm now learning how to use WASM as serverless solution, and found that cloudflare supports Wasm now: https://developers.cloudflare.com/workers/platform/web-assembly/

Just out of curiosity, does any one what's the different of the Wasm solution between fastly and CF? I mean, it would be better to describe the difference in high level, I wanna to to convince my boss to use one of it:
https://www.fastly.com/blog/unlocking-real-time-at-the-edge

WebAssembly (Wasm) · Cloudflare Workers docs

WebAssembly (abbreviated Wasm) allows you to compile languages like Rust, Go, or C to a binary format that can run in a wide variety of environments, …

Unlocking Real-Time at the Edge

We are excited to announce that we have made big strides integrating Fanout into Fastly. We recently announced that Fastly has acquired Fanout in order to unlock real-time web features on our scalable, WASM-based Compute@Edge, our serverless compute offering. Our first step was to add WebSockets support to our Compute@Edge platform.

Hi guys, I'm developing 2 workers for the same project/account, in a Service Binding fashion. When deployed, the workers A is successfully able to call B. But locally, the Service Binding is actually

undefined

undefined

. Anyone can help? I have no idea why it can't see each other when running locally.

This is my env during dev, for Workers A (caller):

[env.dev]
vars = { ENVIRONMENT = "dev", ENV = "dev" }
services = [
  { binding = "SERVICES", service = "workers-services", environment = "dev" }
]

[env.dev]
vars = { ENVIRONMENT = "dev", ENV = "dev" }
services = [
  { binding = "SERVICES", service = "workers-services", environment = "dev" }
]

[env.dev]
vars = { ENVIRONMENT = "dev", ENV = "dev" }
services = [
  { binding = "SERVICES", service = "workers-services", environment = "dev" }
]

[env.dev]
vars = { ENVIRONMENT = "dev", ENV = "dev" }
services = [
  { binding = "SERVICES", service = "workers-services", environment = "dev" }
]

And this is for Workers B (being called):

[env.dev]
name = "workers-services"
vars = { ENVIRONMENT = "dev", ENV = "dev" }

[env.dev]
name = "workers-services"
vars = { ENVIRONMENT = "dev", ENV = "dev" }

When I run with

--remote

--remote

(using Wrangler v3.0.0), I get this error: text: 'workers.api.error.service_binding_env_error: could not resolve binding "SERVICES":
environment "dev" not found for service "workers-services" [code: 10144]'

These are however separate project, one is Bundled (A) and one is Unbound (B). One is nodejs compat (B), one is not (A).

E

Elie Zedeck R.•5/22/23, 12:28 PM

When running with

--remote

--remote

, it spits out the error message just a short time after starting. When running locally (which is the default since wrangler v3.0.0 I assume), the

env.SERVICE

env.SERVICE

env.SERVICE

env.SERVICE is undefined. Running live, no problem.
