I need to send realtime player count data to a database on cloudflare. Does cloudflare support the setup of a websocket server that will listen for a connection and can feed a D1 database?

Hi! Couple of quick questions...

What's the best way to delete a static asset from a user worker? I believe it's possible by creating an upload session and including all the assets except the one you want to remove, but is there something neater, e.g. like
```
DELETE
```
```
DELETE
```
to
```
/accounts/{accountIdentifier}/workers/scripts/{scriptName}/assets/{assetKey}
```
```
/accounts/{accountIdentifier}/workers/scripts/{scriptName}/assets/{assetKey}
```
but for user workers?
If you hit the maximum number of assets for a user worker (which I believe is 20,000 assets), how is it handled? Does it error or does it evict assets, e.g. via FIFO or similar?

Sscruffy Hi! Couple of quick questions... 1. What's the best way to delete a static asset...

H

Hard@Work•2/18/25, 1:51 PM

Your suggestion is the best one at the moment. You can't edit files within a deployment, but you can create a new deployment that doesn't include the asset in question.
It should fail the deployment.

If I wanted to enable users to upload their avatar to

example.my.worker.dev/:user-name/avatar.png

example.my.worker.dev/:user-name/avatar.png

?
Could I use a dispatch worker which calls a single script as the user worker, which makes an upload session request on behalf of the user. If not, where am I going wrong? If it is possible, would I be capped at 20k users?

scruffy•2/18/25, 2:30 PM

Sorry for the contrived example but I'm trying to keep it simple rather than diving into the specific use case, which I have a hunch would be better served by static assets on workers for platforms. With that in mind, is the approach in the previous question possible? (I'd normally just sketch it out in code, but am trying to avoid paying $25 to find the answer, especially if the answer is "nope")

Maybe, though I should note that Assets is built primarily to serve HTML/JS/CSS, and while it can serve other assets, using it primarily to serve non-HTML/CSS/JS assets may run afowl of the terms

Hard@Work•2/18/25, 2:35 PM

I wouldn't think so, though to be sure, I would probably talk with Support. Though note again that using R2/KV should definitely be simpler, and would avoid this terms issue, since it is allowed to serve any kind of assets, including images, json, etc, at any volume

scruffy•2/18/25, 3:41 PM

After some thought, seems that per-user HTML could fit my use case. With that in mind, would it be possible to use a single script as the user worker to enable static asset uploads to

example.my.worker.dev/users/:user-name/index.html

example.my.worker.dev/users/:user-name/index.html

? If so, do the API requests count against my account or the user? Apologies if the question seems bizarre, finding it a bit hard to get my head round things without poking code.

S

scruffy•2/18/25, 8:00 PM

If a Workers for Platforms "script" doesn't contain actually contain a user worker, i.e. it only holds user-specific static assets, does it still count towards the total count of user scripts?

A user Worker with JSON bindings may also be even easier

not sure i follow

S

scruffy•2/18/25, 8:07 PM

(but sounds interesting)

W

Walshy•2/18/25, 8:08 PM

you could upload a user Worker that's literally just

export default {
  fetch(_, env) {
    // will return `{ "whatever": "data" }` as a Content-Type: application/json response
    return Response.json(env.JSON_DATA)
  }
}

export default {
  fetch(_, env) {
    // will return `{ "whatever": "data" }` as a Content-Type: application/json response
    return Response.json(env.JSON_DATA)
  }
}

export default {
  fetch(_, env) {
    // will return `{ "whatever": "data" }` as a Content-Type: application/json response
    return Response.json(env.JSON_DATA)
  }
}

export default {
  fetch(_, env) {
    // will return `{ "whatever": "data" }` as a Content-Type: application/json response
    return Response.json(env.JSON_DATA)
  }
}

And upload the Worker with

"bindings": [
  {
    "name": "JSON_DATA",
    "type": "json",
    "json": {
      "whatever": "data"
    }
  }
]

"bindings": [
  {
    "name": "JSON_DATA",
    "type": "json",
    "json": {
      "whatever": "data"
    }
  }
]

"bindings": [
  {
    "name": "JSON_DATA",
    "type": "json",
    "json": {
      "whatever": "data"
    }
  }
]

"bindings": [
  {
    "name": "JSON_DATA",
    "type": "json",
    "json": {
      "whatever": "data"
    }
  }
]

hi all probably a noob question but how do I exactly use WFP locally?

I see on first page of local development, it says

Support for Workers for Platforms with wrangler dev in local mode is experimental and may change in the future. Use the prerelease branch: wrangler@dispatch-namespaces-dev to try Workers for Platforms locally.

~~but im confused on how to actually enable it. Is there an experimental flag I have to use? do I need to download wrangler globally? or something else? Thanks!~~

EDIT: Im dumb. Just did:

        "wrangler": "dispatch-namespaces-dev"

        "wrangler": "dispatch-namespaces-dev"

However, now I got this error:

ERROR] Missing entry-point: The entry-point should be specified via the command line (e.g. `wrangler dev path/to/script`) or the `main` config field.

ERROR] Missing entry-point: The entry-point should be specified via the command line (e.g. `wrangler dev path/to/script`) or the `main` config field.

even though I have path specified in wrangler. I resolved by just adding the path to the dev script but seems like a regression.

EDIT 2: seems like experimental flag also ignores specified port for wrangler to listen to in wrangler.jsonc

Is anyone able to help me with a

request.cf

        return new Response(
