Can someone confirm that this is actually supported in this wrangler dev branch release? Or is uploading scripts the only way to debug WFP apps?

I am getting this error when creating a new cloudflare worker - workers.api.error.exceeded_allowed_number_of_scripts. When I checked the cloudflare docs it suggested to upgrade to Cloudflare Workers for Platforms. And I upgraded the plan. But I am still getting this error. Can anyone help me with it?

Walshy•1/9/25, 1:49 PM

Workers for Platforms is indeed the solution, you'll want to switch to uploading the scripts as Workers for Platforms scripts rather than regular Workers

https://developers.cloudflare.com/api/resources/workers_for_platforms/subresources/dispatch/subresources/namespaces/subresources/scripts/methods/update/

Walshy•1/9/25, 5:07 PM

For #1 you should follow the same as #2, add them to ssl for saas and add a CNAME to your main zone

Walshy•1/9/25, 5:08 PM

And yeah, for you it seems you can just keep using 1 worker, let it get invoked by ssl for saas and it'll be handled for all customers with ease

Walshy•1/9/25, 5:19 PM

I don't think there is a limit on hostnames?

Walshy•1/9/25, 5:19 PM

Workers for Platforms wouldn't grant you anything extra but would cost more

MMatt yeah there is: https://developers.cloudflare.com/cloudflare-for-platforms/cloudf...

Walshy•1/9/25, 5:20 PM

huh til

Walshy•1/9/25, 5:20 PM

ssl for saasing this fully is the only scalable solution unfortunately.

Walshy•1/9/25, 5:21 PM

We have a limit on the amount of zones a Worker can be linked to, I think it's 100 so you'd hit that much quicker than the saas limit

Walshy•1/9/25, 5:22 PM

You only need 1 route - */**/*

Walshy•1/9/25, 5:22 PM

That will accept all hostnames and all paths

juanferreras•1/15/25, 10:26 PM

ended up using https://github.com/val-town/codemirror-ts with pretty good results (you do need to upload the built output to wrangler) for a single-file user worker.

it's pretty good but still kind of missing a way to let users add a dependency – it'd be pretty cool to defer this to the API or to wranglerwrangler somehow to build/bundle correctly

Can I use workers-for-platforms to dynamically create vectorize database per customer?

arun2728•1/27/25, 9:53 AM

Hi there, I am using cloudflare workers for platform. I want to create a Create a dynamic dispatch Worker that can route the request to the correct worker by extracting the details from the hostname.

Eg: My dispatch workers should be able to accept all the requests for the domain: *.route.example.com*.route.example.com And route it to the child worker using the subdomain.

testing-1.route.example.com -> dispatch worker 1
testing-2.route.example.com -> dispatch worker 2

This is my sample routing script from the docs: https://developers.cloudflare.com/cloudflare-for-platforms/workers-for-platforms/get-started/dynamic-dispatch/

But docs doesn't specify how to setup domains to make it work. I am unable to figure out how to set the route or domain to my dispatcher worker so that I can accept requests. How can I do this? Can anyone help me with this?

export default {
  async fetch(request, env) {
    try {
      // parse the URL, read the subdomain
      let workerName = new URL(request.url).host.split('.')[0];
      let userWorker = env.dispatcher.get(workerName);
      return await userWorker.fetch(request);
    } catch (e) {
      if (e.message.startsWith('Worker not found')) {
        // we tried to get a worker that doesn't exist in our dispatch namespace
        return new Response('', { status: 404 });
      }

      // this could be any other exception from `fetch()` *or* an exception
      // thrown by the called worker (e.g. if the dispatched worker has
      // `throw MyException()`, you could check for that here).
      return new Response(e.message, { status: 500 });
    }
  },
};

export default {
  async fetch(request, env) {
    try {
      // parse the URL, read the subdomain
      let workerName = new URL(request.url).host.split('.')[0];
      let userWorker = env.dispatcher.get(workerName);
      return await userWorker.fetch(request);
    } catch (e) {
      if (e.message.startsWith('Worker not found')) {
        // we tried to get a worker that doesn't exist in our dispatch namespace
        return new Response('', { status: 404 });
      }

      // this could be any other exception from `fetch()` *or* an exception
      // thrown by the called worker (e.g. if the dispatched worker has
      // `throw MyException()`, you could check for that here).
      return new Response(e.message, { status: 500 });
    }
  },
};

Create a dynamic dispatch Worker · Cloudflare for Platforms docs

After you have created a dispatch namespace, you can fetch any user Workers in the namespace using a dynamic dispatch Worker. The dynamic dispatch Worker has a namespace binding.

I changed my hosting server from bluehost to cloudflare for ssl/tls and free CDN service. I did updated the dns records to cloudflare ones and I also stopped auto-ssl from bluehost but still I'm unable to use Cloudflare ssl. (Should i need to delete bluhost ssl certificates???)

rob•1/31/25, 3:02 PM

Can you bind a specific gateway to a worker on wfp!

rob•1/31/25, 3:02 PM

Or does binding it to AI give it access to all gateways?

Advany•2/1/25, 8:25 PM

We have customers developing a workflow as a worker using ai. We deploy that to wfp as a worker with endpoints like /step1 to /step10.

We where thinking of using a durable object to call the worker thats deployed. For example first step1, get result, then call step2, etc. Untill done.

Is there a better way? Steps can take while waiting for external apis like ai

This isn't directly related to WfP, so I recommend asking in #workers-help or #workers-and-pages-discussions :meowwink:

apignotti•2/6/25, 9:23 AM

Morning all. I have a question about WfP and legal responsibility for outbound traffic from final users.

Let's assume a final user of my service (built on WfP) generate malicious/illegal traffic. It would be my responsibility to help law enforcement track the original user of the traffic. Does CF provide any builtin auditing/logging functionality to help in this or all WfP users must create a solutions from scratch?

Walshy•2/6/25, 12:46 PM

Very interesting question, let's talk through it

So, in the case of someone hosting something malicious, you'll likely receive a domain. You'll know what customer that domain tracks to.
You also control the upload path so you can log who uploads what and when.
I'd recommend also having analytics/logs for general traffic (Analytics Engine + Workers Logs would be ideal)

Then for a user Worker sending requests maliciously, we have Outbound Workers which again you can use to track analytics + Logs and tie these outbound requests to specific customers

WWalshy Very interesting question, let's talk through it So, in the case of someone hos...

apignotti•2/6/25, 12:49 PM

Right! Outbound Workers were the concept I was missing. I see this covers fetch explicitly, but how does this interact with TCP Socket API? Do the outbound workers intercept those too? Or is the TCP Socket API maybe disabled in WfP?

Walshy•2/6/25, 12:50 PM

I don't believe TCP would be covered but that's a good callout, I didn't think of that. Let me bring that up with the PM
