Is anyone able to help me with a

request.cf.zoneName

request.cf.zoneName

issue? My website is hosted on CF Pages. I am using a CF Worker and want to limit the ability to make an api request to specific zoneName's. The issue I am running into is that

request.cf

request.cf

is always NULL. FWIW The code is below, but I have a feeling this might be a DNS or Routing issue. Any and all help would be appreciated.

    // Verify Cloudflare zone
    console.log(request.cf);
    console.log(allowedDomains);
    console.log(request.cf.zoneName);
    console.log(allowedDomains.includes(request.cf.zoneName));
    if (!request.cf || !allowedDomains.includes(request.cf.zoneName)) {
        console.log('[Security] Access denied: Invalid Cloudflare zone');
        return new Response(
            JSON.stringify({ error: 'Access denied' }),
            { status: 403, headers: { 'Content-Type': 'application/json' } }
        );
    }

Thank you for your help. Another problem is it seems my wrangler.jsonc is not being picked up? I can get arount by just specifying the path in the script but seems like the

dispatch_namespaces

dispatch_namespaces

config is not being picked up either?

If you're using the

dispatch-namespaces-dev

branch I'm not sure that supports wrangler.json by default yet..

I don't like these branches for these reasons :/

one thing I'm a bit confused on how the version works. like just to confirm this is what wrangler should be in package.json? I honestly didn't know you could have a name for versioning haha

Service bindings are for your regular workers only. You must use a dispatch binding to access workers in namespaces.

how do we access the args object from dispatcher in a user worker? I am trying it locallly following the guide but cant figure it out.
From the types

(method) DispatchNamespace.get(name: string, args?: {
    [key: string]: any;
}, options?: DynamicDispatchOptions): Fetcher
@param name — Name of the Worker script.


@param args — Arguments to Worker script.

@param options — Options for Dynamic Dispatch invocation.

@returns — A Fetcher object that allows you to send requests to the Worker script.

@throws — If the Worker script does not exist in this dispatch namespace, an error will be thrown.

I want to be able to do something like:

    .get("/", async (c) => {
        const customerScript = c.env.DISPATCHER.get("user-worker-dev", {
            hook: "afterCreate",
            table: "order",
        });
        return await customerScript.fetch(c.req.raw);

    .get("/", async (c) => {
        const customerScript = c.env.DISPATCHER.get("user-worker-dev", {
            hook: "afterCreate",
            table: "order",
        });
        return await customerScript.fetch(c.req.raw);

    .get("/", async (c) => {
        const customerScript = c.env.DISPATCHER.get("user-worker-dev", {
            hook: "afterCreate",
            table: "order",
        });
        return await customerScript.fetch(c.req.raw);

    .get("/", async (c) => {
        const customerScript = c.env.DISPATCHER.get("user-worker-dev", {
            hook: "afterCreate",
            table: "order",
        });
        return await customerScript.fetch(c.req.raw);

Hi, when uploading static assets with a normal worker, after deploying the worker, I'm automatically directed to the uploaded index.html file with js and css. However, if I deploy a platform worker and route to it with a dispatch worker, I can't get the app to be displayed. Is there any way serve files from platform worker to dispatch worker?

W

Walshy•3/5/25, 10:59 AM

Can you provide more info? It'll work the same way

Silvan•3/5/25, 12:37 PM

I honestly have a hard time understanding all use cases for platforms

lets say i sell unique websites to customers while also owning the domain. does this product still make sense? because so far normal workers can do the things i need

SSilvan I honestly have a hard time understanding all use cases for platforms lets say ...

A

Acе•3/5/25, 2:10 PM

No, that wouldn’t make sense for workers for platforms. It is more for giving the users of your website the ability to create their own workers, that usually extends the functionality of your website/app. For example, Shopify can use it to enable developers to create plugins for the checkout page, such as collecting additional information related to an order (e.g. a loyalty card number).

Hello community,

I’m trying to deploy a nuxt site to cloudflare. I used the nuxt starter from the cli.

But I haven’t been able to use the workers for the /server/api together with the hono library.
I get internal server error. And not functionality for the server/api

I haven’t this in my nuxt.config
export default defineNuxtConfig({
compatibilityDate: "2024-11-01",
devtools: { enabled: true },

nitro: {
preset: "cloudflare-module", // ← Correct preset here
},

modules: ["nitro-cloudflare-dev"],
vite: {
optimizeDeps: {
include: ["hono"],
},
},
});

I have this in my wrangler

{
"$schema": "node_modules/wrangler/config-schema.json",
"name": "test-1",
"compatibility_date": "2025-03-03",
"compatibility_flags": ["nodejs_compat"], // ← Required
"main": "./.output/server/index.mjs",
"assets": {
"binding": "ASSETS",
"directory": "./.output/public/"
},
"r2_buckets": [{ "binding": "BUCKET", "bucket_name": "your-bucket-name" }],
"kv_namespaces": [{ "binding": "KV", "id": "your-kv-id" }],
"d1_databases": [

"database_name": "your-db-name",
"database_id": "your-db-id"
}
],
"ai": { "binding": "AI" },
"observability": { "enabled": true }
}

This my workers code:

// server/api/workers.js
import { Hono } from "hono";

const app = new Hono();

app.get("/", (c) => {
const name = c.req.query("name") || "World";
return c.json({ greeting:

Hello, ${name}!

Hello, ${name}!

});
});

export default app;

thomasjiangcy•3/10/25, 3:45 PM

is there anyway to query bandwidth usage on a worker level within a dispatch namespace? e.g. want to charge for bandwidth as part of pricing

W

Walshy•3/10/25, 4:25 PM

Workers has no concept of bandwidth usage so no, not through our side

W

Walshy•3/10/25, 4:25 PM

though actually...

W

Walshy•3/10/25, 4:26 PM

you could sum { responseBodySize } in graphql, looks like we have responseBodySize in subrequests dataset too. don't think we have ingress but there's some data you could start to use

even for dispatch-namespaces-dev branch?

oh no, you'd need the flag there (if it's supported i'm not 100% sure)

W

Walshy•3/10/25, 4:54 PM

but there's not really much info other than it allows wrangler.json

D

darkpoolOP•3/10/25, 4:56 PM

ok thanks just to make sure im not using flag wrong it would be like this:

npx wrangler@dispatch-namespaces-dev dev --x-json-config

correct?

Hi, just trying to follow the Workers for Platforms example but having trouble getting dispatch_namespaces to work. in my wrangler.jsonc:

"vars": {
  "MY_VARIABLE": "production_value",
},

"dispatch_namespaces": [
  {
    "binding": "DISPATCHER",
    "namespace": "<NAMESPACE_NAME>",
  },
],

"vars": {
  "MY_VARIABLE": "production_value",
},

"dispatch_namespaces": [
  {
    "binding": "DISPATCHER",
    "namespace": "<NAMESPACE_NAME>",
  },
],

"vars": {
  "MY_VARIABLE": "production_value",
},

"dispatch_namespaces": [
  {
    "binding": "DISPATCHER",
    "namespace": "<NAMESPACE_NAME>",
  },
],

  "MY_VARIABLE": "production_value",
},

"dispatch_namespaces": [
  {
    "binding": "DISPATCHER",
    "namespace": "<NAMESPACE_NAME>",
  },
],

But when i run wrangler dev with:

export default {
  async fetch(req, env) {
    console.log('env:', Object.keys(env));

export default {
  async fetch(req, env) {
    console.log('env:', Object.keys(env));

I see logged:

env: [ 'MY_VARIABLE' ]

env: [ 'MY_VARIABLE' ]

Why do does

"vars"

"vars"

modify env but

"dispatch_namespaces"

"dispatch_namespaces"

doesn't?

preston•3/10/25, 9:46 PM

Apparently the answer is that

"dispatch_namespaces"

"dispatch_namespaces"

doesn't work in local dev mode right now, because I tried deploying and env does have a DISPATCHER key in prod. Is that a bug? The output from

wrangler dev

wrangler dev

implies that it is working:

lusons•3/11/25, 3:28 PM

Thanks for your reply, I'm not sure if my idea is correct. In my scenario, I want to deploy the html + otherAssets + userWorker.js produced by the saas service to a worker, and then distribute it by dispatcher (similar to the publishing function of framer.com), but currently I can only use base64 for network transmission, which will be very slow. Or do I have other ways?

W

Walshy•3/11/25, 3:29 PM

using Workers Assets yeah it'd be base64 but that shouldn't be slow unless you're uploading a lot of data, for almost all sites it should take almost no time at all. We recommend concurrent uploads of these asset buckets

is this an error? I dont see any mention of `dispatch_namespace` in https://developers.cloudflare.co
