Actually, I probably need more flexibility with storing/loading my DOs, so I'll probably use D1 or something else to keep track of them rather than using the API.

JJacob Wright It appears https://github.com/kriszyp/msgpackr can support structured cloning

Larry•3/8/23, 1:30 AM

I use https://github.com/kriszyp/cbor-x by the same author. CBOR is essentially msgpack but with an international standard. It's fast and easy to work with.

Anyone using DO for any production use-case as a replacement for Web-sockets? If yes, what is your monthly bills for the same on Cloudflare?

I ran some tests and within few tests the dashboard was showing 100s GB-s (something similar, not sure) but at that point I abandoned the idea.

My existing implementation use sockets via Pusher and I am on a $49/month plan.
I can check the pricing examples here: https://developers.cloudflare.com/workers/platform/pricing/#durable-objects-billing-examples but that does not contain any real examples so it would be great if someone here can help us figure out the estimated costs.

Hello, I’m Allie!•3/8/23, 7:32 AM

Running a DO non-stop costs about $4 a month, and a single DO can handle multiple WS connections, so you could probably get pretty far there, depending on what you are doing

Hello, I’m Allie!•3/8/23, 7:32 AM

Also note, if you can fit it all in a single DO, then it qualifies for the “free” tier

Is there a quick way to purge all DOs for a service without deleting the service? Doing a

wrangler delete && wrangler publish

wrangler delete && wrangler publish

Larry•3/9/23, 12:40 PM

Would a try/catch approach when you do an operation in a DO on a document work? Then you could retry triggering your different way.

Is there an easy way to achieve self destructive ephemeral DOs? I'd love to have my user sessions backed by a DO but have it destroyed if no requests are made for a certain period of time

DanTheGoodman•3/9/23, 1:58 PM

Set an alarm for some time after every request (say

new Date().getTime() + 5000

new Date().getTime() + 5000

for a 5 second delay) and in the alarm handler just call

.deleteAll()

.deleteAll()

johtso•3/9/23, 1:59 PM

And I guess replace the previous alarm each time

DanTheGoodman•3/9/23, 1:59 PM

SetAlarm will upsert it

DanTheGoodman•3/9/23, 1:59 PM

so it will replace if it already exists, or set if it does not

Another question, what's the go to way to get a type safe interface between my DO and my worker? Something like trpc?

johtso•3/9/23, 2:17 PM

Does itty router help with this?

Larry•3/9/23, 2:43 PM

There might be a way to use native TypeScript types that I don't know of, but I use vanilla JavaScript so I've settled on @cfworker/json-schema

DanTheGoodman•3/9/23, 3:23 PM

they are bound together, and can share types in the codebase

DanTheGoodman•3/9/23, 3:23 PM

Do you mean runtime-safe? It's better to validate inputs and assume they are as expected once they enter the system rather than checking everywhere

DanTheGoodman•3/9/23, 3:24 PM

If you need runtime type checking you can use something like zod

DanTheGoodman•3/9/23, 3:24 PM

Hono has better typing across the board, I've used both itty-router and hono. I prefer to stay away from itty-durable but that would have better typing. I stay away because I don't like how differnet it is from making normal DOs

johtso•3/9/23, 3:25 PM

@danthegoodman this looks promising https://www.npmjs.com/package/trpc-durable-objects

npm

trpc-durable-objects

Testing out trpc for durable objects. Latest version: 1.0.4, last published: 19 days ago. Start using trpc-durable-objects in your project by running

npm i trpc-durable-objects

npm i trpc-durable-objects

. There are no other projects in the npm registry using trpc-durable-objects.

johtso•3/9/23, 3:25 PM

Just looking to reduce boilerplate

DanTheGoodman•3/9/23, 3:25 PM

Are you just trying to get strong type checking?

DanTheGoodman•3/9/23, 3:26 PM

just type check when requests come it, then you can assume they are safe once they are in the system

DanTheGoodman•3/9/23, 3:26 PM

so at the worker type check everything before passing to a DO

DanTheGoodman•3/9/23, 3:26 PM

many many packages for that

johtso•3/9/23, 3:26 PM

I want to be able to call a method of my DO from my worker as if it was a local function, and have the correct types, and have the response validated

DanTheGoodman•3/9/23, 3:28 PM

Ultimately you will be at the mercy of that package, it's not really worth it in my experience of making many production systems on workers and DOs. Keep with the request/response semantics because that is what's actually happening, and that decouples you from dumb decisions or lack of updates from third party packages

DanTheGoodman•3/9/23, 3:28 PM

but that's very much an opinion... personally I'd never use a small package like that in production, I'm not about to maintain someone else's code when I need changes if that makes sense

DanTheGoodman•3/9/23, 3:29 PM

going from 5 lines per function to 2 is not worth all that hoop jumping IMO

DanTheGoodman•3/9/23, 3:29 PM

premature optimization is the common terminology here

Jjohtso @Kevin W does itty-durable "just work" when it comes to types?

Kevin•3/9/23, 3:31 PM

Currently itty-durable itself (the invisible code) is not typed at all, but you can easily type your objects as you define them, then use those types throughout your worker code.

johtso•3/9/23, 3:39 PM

For example will the return value of COUNTER.get('myCounter').currentValue()COUNTER.get('myCounter').currentValue() be typed as a number if the DO method returns a number?

johtso•3/9/23, 3:49 PM

Looks like there's no typescript stuff going on, so you'd have to do something like as ReturnType<typeof Counter.currentValue>as ReturnType<typeof Counter.currentValue>

Kevin•3/9/23, 4:07 PM

I would do something like const MyObj = DO.get(‘foo’) as MyDurableClass

johtso•3/9/23, 4:08 PM

Oh wow, that's a great idea
