hi folks,

hi folks, i'm leveraging DO for a websocket w/ hubernation support, but keen to understand how i can pass on context to my "webSocketMessage". i want to simply pass on the user id of the user into the webSocketMessage handler. when it gets hibernated, it seems to get lost. i'll drop my fairly basic code in a thread....

Cloudflare adapter is unable to export D...

FYI - this is just a heads up regarding Astro and Durable Objects It appears that the current astro/cloudflare adapter is unable to build a worker which exports classes for durable objects This means that even if you use workers assets with Astro, you still can't combine your durable object code with other Astro SSR code in one worker. I have filed https://github.com/withastro/adapters/issues/494 Repro in https://github.com/jldec/astro-do/pull/1...

Websocket Server with Durable Object Client Connection

There is no point doing the work from

There is no point doing the work from the worker since you will hit huge latencies. You worker could be on one side of the world and your DO on the other. If you want remote access to SQLite, might as well use D1 and get the other niceties too. Each await stub.something() you call is a roundtrip. You can pipeline several together if you design your DO class properly but even that's very limited. ...

Hello 👋 , are there any guides/examples

Hello 👋 , are there any guides/examples on how one might do an transfer migration? We have 5 DOs and we want to split 3 DOs to a separate worker that has a very simple worker bundle leading to faster startup times. I don't see much info on the docs here https://developers.cloudflare.com/durable-objects/reference/durable-objects-migrations/

Hi.

Hi. I'm seeing a strange behavior of wasm in DurableObjects, especially when alarms are used. I saw this exception in logs before we were using alarms (when response was synchronous), but now it started happenning very often. The library used is automerge. After a DO gets into a "broken state", an exception is raised for any library method call in the code produced by wasm-bindgen:...

but the state is not consistent in a concurrent requests
Can you give more details what exactly are you doing here? A Durable Object runs a single request at a specific point in time, and only schedules a different request when you do async IO in your logic. So as long as you are only doing synchronous operations, or one of the transaction() methods on the storage API that allow you to use async actions, your storage access should be consistent....

Hey there. Is there any possibility we

Hey there. Is there any possibility we could get a method for hibernatable websockets to set/update the tags on an already established connection? I'm using tags as a rudimentary way to publish messages to subscribers of given topics, and it'd be nice to be able to change a subscriber's topics without needing it to reconnect. I could probably use a serialized attachment for that, but then I'd need to iterate over all connections whenever publishing a message which seems problematic in its own way....

sort of, i use drizzle kit to manage migrations and a custom query proxy which applies the same types used in drizzle kit to queried results (i.e. int to js date, etc.)

Hi everyone, I'm new to durable objects

Hi everyone, I'm new to durable objects and don't understand much from the front page of their docs. (This seems to be a trend with CF; the docs could definitely be more non-expert-friendly. Reading "without requiring you to build serialization and coordination primitives on your own." on the very first page is quite daunting). I would like to understand what this product is and whether it matches my need. I need something that can power websocket-like behaviour to buld a realtime chat. Previously I've used pusher.com for this. Is that the sort of thing DO is? Or how does it compare to Queues, which, to a layman like me, also sounds sort of like what's needed? Any layman help appreciated! 🙂...

Hey 👋 I have a DO based off of this

Hey 👋 I have a DO based off of this https://github.com/cloudflare/workers-chat-demo and its working great.. but client connected sockets timeout (close with code 1006) if no messages are sent after exactly 3 minutes.. is this expected? I have tried calling state.setWebSocketAutoResponse in the DO constructor (not sure how to use this method) but that didn't seem to do much. Do I need to have connected clients send a ping messages to the DO at a regular interval to keep the connection open? If so, does this wake the socket from hibernation (and thus incur a charge)?...
