Has anyone else noticed some really weird issues with websockets where if you try to disconnect it just doesnt disconnect? Testing with https://hoppscotch.io/realtime/ anytime I click disconnect nothing happens. But when using other WS servers it disconnects fine.

Ah interesting... if a client doesnt send a message to the server and you click disconnect it gets stuck in the closing state for a while I always refreshed to fast. If I send a message then click disconnect its instant.

Is this because the DO isn't "hot"? You only have 500ms.

anyone have statsd metrics for datadog that work inside a DO/worker?

is there a way to get lat and long inside a DO?

vans163

04/28/2021, 3:14 AM

or does it currently need to be passed in from the worker?

So in-memory storage means some space allocated for DO not worker. All state would be only in DO. Those data in DO should not be moved to worker and perform any computation?

That actually was just normal worker websockets havent gotten to get it to work on DO yet because itty-durable has a bug with it so not entirely sure but possibly something like that.

Currently, the

cf

object is unavailable in module workers, but it sounds like the info will be available at some point in some form in the future. For DO fetches though, you'll probably always want to pass it in from the original client request https://discord.com/channels/595317990191398933/773219443911819284/834489479833059370

Having issues with my durable objects:

Copy code

toml
# wrangler.toml
[durable_objects]

bindings = [{name = "ROLE_MANAGER", class_name = "RoleManager"}]

Copy code

typescript
// role-manager-durable-object.ts
export class RoleManager implements DurableObject {
...
// index.ts
import { RoleManager } from './role-manager-durable-object'

export default {
  async fetch(request: Request, env: Env) {
    try {
      env.ROLE_MANAGER.idFromName('someId')
    } catch (e) {
      return new Response(e.message)
    }
    return new Response('')
  }
}

export { RoleManager }

and ive run

wrangler publish --env production --new-class RoleManager

and this code returns

Cannot read property 'idFromName' of undefined

@User does the

Env

type include the

ROLE_MANAGER

property? If so, its very likely the problem here is with your typescript setup -- whats your typescript config and build process look like?

Yoni

04/28/2021, 9:11 PM

Its just an interface

Copy code

ts
export interface Env {
  DISCORD_APP_ID: string
  DISCORD_PUBLIC_KEY: string
  DISCORD_TOKEN: string
  ROLE_MANAGER: DurableObjectNamespace
}

it shouldnt affect the code right? in the outputted

index.mjs

, i see

...async fetch(e,n){try{n.ROLE_MANAGER...

Yoni

04/28/2021, 9:12 PM

ill paste my ts and rollup configs

Yoni

04/28/2021, 9:12 PM

Copy code

json
{
  "compilerOptions": {
    "outDir": "./tsc-dist",
    "module": "ESNext",
    "target": "ES2019",
    "lib": ["esnext", "webworker"],

Copy code

js
import { terser } from 'rollup-plugin-terser'
import { nodeResolve } from '@rollup/plugin-node-resolve'
import commonjs from '@rollup/plugin-commonjs'

export default {
  input: 'tsc-dist/index.js',
  output: {
    exports: 'named',
    format: 'es',
    file: 'dist/index.mjs',
    sourcemap: false,
  },
  plugins: [commonjs(), nodeResolve({ browser: true }), terser()],
}

are you using wrangler environments?

matt

04/28/2021, 9:13 PM

the

[durable_objects]

section isn't inherited

Yoni

04/28/2021, 9:13 PM

ooo so i need to do

Copy code

toml
[env.production.durable_objects]
bindings = [{name = "ROLE_MANAGER", class_name = "RoleManager"}]

matt

04/28/2021, 9:13 PM

yup!

Yoni

04/28/2021, 9:13 PM

let me try that rn

matt

04/28/2021, 9:13 PM

the migrations will need to be done for each environment as well, as each environment is its own script

matt

04/28/2021, 9:14 PM

ts/rollup config looks good

Yoni

04/28/2021, 9:14 PM

that worked! now i get

Some functionality, such as asynchronous I/O, timeouts, and generating random values, can only be performed while handling a request.

i probably just did something wrong

matt

04/28/2021, 9:15 PM

that's thrown when you try to do something in global scope or a durable object constructor that falls under that category
