for uploading entire user worker use https://developers.cloudflare.com/api/resources/workers_for_platforms/subresources/dispatch/subresources/namespaces/subresources/scripts/methods/update/

which accepts multi part form data so modules, assets, bindings, etc.

PUT script content is just for updating the JS.

Can user workers define their own durable objects, e.g.

class UserDurableObject extends DurableObject<Env>

class UserDurableObject extends DurableObject<Env>

class UserDurableObject extends DurableObject<Env>

class UserDurableObject extends DurableObject<Env>?

For instance, what if I wanted a user worker to receive emails. A standard worker would define an

send_email

send_email

send_email

send_email binding. What would a secure setup look like where the email goes through the dispatch worker, and for any user worker supporting email, it would pass it on to be handled by the user worker?

darkpool•6/5/25, 2:39 PM

not sure about DO support since I have not tested it but if you want to pass params from dispatch to user worker you can do it via RPC. User workers can also have bindings to other (non-user) workers so if you had a tools worker with sendEmail method, your user worker could bind to it.

christianklotz•6/5/25, 2:50 PM

Thank you! I saw the RPC stuff too. The bottom line is that user workers then always would have to be slightly different than 'regular' workers? I'm still trying to wrap my head around how user workers would have to be written differently.

darkpool•6/5/25, 2:58 PM

Np. It took me a while to wrap my head around it too. Basically the only difference is how they're invoked. So a regular worker can't RPC a user worker, only a dispatch worker can. However, a user worker can RPC a regular worker directly. The docs dont show this but RPC does work

hi all. I was trying to get workers for platforms working, but following the tutorial I couldn't get localdev setup. Does that tutorial still work?
Couldn't find

wrangler dev

session for "customer-worker-1" in namespace "test" to proxy to

here's the wrangler config for the user-worker:

obviously there's a linter error there (why I screenshotted) - but that is what the tutorial says to do

Your Worker has access to the following bindings:

Durable Objects:
- MAIN_RUN_DO: MainRunObject
KV Namespaces:
- SEND_PROTECT: e5010ba5c178462a8ca7f227d7efa494 [simulated locally]
Dispatch Namespaces:
- DISPATCH_NAMESPACE: test [connected to remote resource]

But when trying to actually run the worker:

thanks for the help. unfortunately i tried globally installing wrangler, npx wrangler, running it direct from CLI etc. and all permutations failed. also tried replacing .jsonc with .toml
i don't know if there's any debugging steps available for wrangler

ok wow the restart seemed to help (even though the processes were restarted many, many times) - thank you @darkpool

You can use DO KV, but you have to add a migration to your wrangler.toml/wrangler.jsonc file. Can you show what you have currently?

Does Workers for Platforms work with Durable Objects? I didn't see that mentioned in the documentation. Thanks!

D

demotime•6/6/25, 7:47 AM

does anyone know whether we can run user-workers with a regular http url/api, or if it's ONLY via. the dynamic dispatch worker?

D

demotime•6/6/25, 8:06 AM

it's very awkward running locally, because the flow goes:

edit user code & run

but the APIs to create/edit users-workers seem to not have a local equivalent. so there's no (simple) way to save and test a change, which is pretty fundamental WFP interaction? Also makes it very hard to test the combined code when we add platform stuff to user-stuff

if there's a way to just run the production worker from local that would be one solution I think. interested how anyone else gets around this or what I'm missing

i guess i could deploy a proxy dispatch worker, then abstract a proxyOrRun method, if env.proxyDispatchUrl is set go via. that. anyone happen to know any best practice or workflow which would let us deploy and test scripts locally (local env, local dispatch worker, scripts either locally emulated or production ones)

does that also create the worker or does it only work if the worker already exists though
