Lluna is there a way for a worker to get the name from it's `wrangler.toml` at runtime...

Nope. There is theoretically a binding that has it but it's not stabilised so it could be removed/broken at any time.

dang it, is there an easy way to sub out a placeholder at build time with workers?

K

kian•4/27/24, 2:50 AM

--define

--define

--define

--define (or

define

define

in TOML) is build-time replacement (https://esbuild.github.io/api/#define)

K

kian•4/27/24, 2:50 AM

[define]
WORKER_NAME = '"foo"'

[define]
WORKER_NAME = '"foo"'

[define]
WORKER_NAME = '"foo"'

[define]
WORKER_NAME = '"foo"'

lunaOP•4/27/24, 2:50 AM

oh that'd be perfect

K

kian•4/27/24, 2:50 AM

(quotes are important, if you just do

"foo"

"foo"

"foo"

"foo" then it will be an identifier rather than a string)

lunaOP•4/27/24, 2:51 AM

oh yep i remember hitting that in the past with tsup (esbuild)

K

kian•4/27/24, 2:51 AM

The old version of https://developers.cloudflare.com/workers/runtime-apis/bindings/version-metadata/ that wasn't stabilised used to have a

.name

.name

.name

.name property - I think they'd be open to adding it onto that binding though, I don't see why not.

anywhere i could pass on feedback in favour of that?

The old binding was...

{"name":"test-worker","deployment":{"id":"1a737aad-3c1a-40bf-90aa-4c0d1f840e13","number":51,"timestamp":"2024-04-27T02:52:40.970522Z"}}

The new one is...

If it's just for testing, you can use the old binding still

[[unsafe.bindings]]
name = "METADATA"
type = "metadata"

[[unsafe.bindings]]
name = "METADATA"
type = "metadata"

[[unsafe.bindings]]
name = "METADATA"
type = "metadata"

[[unsafe.bindings]]
name = "METADATA"
type = "metadata"

I just wouldn't recommend it for production since, whilst I really doubt it as it's been around for awhile, they could remove it and then the API will start rejecting uploads till it's removed

Hi there, just a quick question to be sure or to find out if I'm doing something wrong. Do WorkerEntrypoints for RPC communication between workers have to be defined in the “index” file? I've tried to place it elsewhere and it's not recognized.
In any case, 260ms response time for 3 subrequests ( 4 with D1 ) is just insane. gg for work it works like a charm.

K

kian•4/27/24, 3:35 PM

You probably need

export { Foo } from './foo'

export { Foo } from './foo'

export { Foo } from './foo'

export { Foo } from './foo' in your index.js/ts

Kkian You probably need `export { Foo } from './foo'` in your index.js/ts

Y

Yakuzo•4/27/24, 3:40 PM

So I need to import my file into index and that's it?
Currently, here's what I've done:

// entrypoint/userEntrypoint.ts
// Not recognize in this file
export class UserStore extends WorkerEntrypoint<Env> {
  ...
}

// entrypoint/userEntrypoint.ts
// Not recognize in this file
export class UserStore extends WorkerEntrypoint<Env> {
  ...
}

// entrypoint/userEntrypoint.ts
// Not recognize in this file
export class UserStore extends WorkerEntrypoint<Env> {
  ...
}

// entrypoint/userEntrypoint.ts
// Not recognize in this file
export class UserStore extends WorkerEntrypoint<Env> {
  ...
}

// index.ts
// If I copy all UserStore content in index, it's ok.
export default class extends WorkerEntrypoint {
    async fetch() {
        const response = `
            Version: 1.0.0\n
            Code Name: Piston
            Description: Database Worker\n
            Changes: Initial version\n
            Health Check: OK
        `;

        return new Response(response, { status: 200 });
    }
}

// index.ts
// If I copy all UserStore content in index, it's ok.
export default class extends WorkerEntrypoint {
    async fetch() {
        const response = `
            Version: 1.0.0\n
            Code Name: Piston
            Description: Database Worker\n
            Changes: Initial version\n
            Health Check: OK
        `;

        return new Response(response, { status: 200 });
    }
}

// index.ts
// If I copy all UserStore content in index, it's ok.
export default class extends WorkerEntrypoint {
    async fetch() {
        const response = `
            Version: 1.0.0\n
            Code Name: Piston
            Description: Database Worker\n
            Changes: Initial version\n
            Health Check: OK
        `;

        return new Response(response, { status: 200 });
    }
}

// index.ts
// If I copy all UserStore content in index, it's ok.
export default class extends WorkerEntrypoint {
    async fetch() {
        const response = `
            Version: 1.0.0\n
            Code Name: Piston
            Description: Database Worker\n
            Changes: Initial version\n
            Health Check: OK
        `;

        return new Response(response, { status: 200 });
    }
}

So I just need to import ?

import { UserStore } from "./entrypoints/userEntrypoint"

import { UserStore } from "./entrypoints/userEntrypoint"

import { UserStore } from "./entrypoints/userEntrypoint"

import { UserStore } from "./entrypoints/userEntrypoint"

But how do I use it in the index?

I see there have been some discussion about logging libraries in the past, but am wondering if anything has changed in that regard since most of the threads I find are a few years old.

Are people using some nice structured logging libraries for workers written in TS/JS? Last time I checked Pino doesn't work in CF Workers.
I don't need any transporters or other fancy stuff since I'm using the Baselime integration with tail workers. I also have the

otel-cf-workers

otel-cf-workers

otel-cf-workers

otel-cf-workers package setup, so I'd want to attach logs to traces automatically and have the logs easily searchable within Baselime.

sanity check, if my Worker does a subrequest to another zone on Cloudflare, I can't override the cache, right?

P

pippin_mole•4/28/24, 5:50 PM

I need a tiny bit of 'state' between each worker run - in that I have an array of locations an an array of jobs. When a worker runs, it should pick a job and location, run a bit of logic and then 'update' the state to point to the next job (so the next worker does its work on a different job)

P

pippin_mole•4/28/24, 5:50 PM

Does anybody have a good idea on how to manage this tiny state?

How about KVStore?

U

Unsmart•4/28/24, 6:46 PM

KV wouldnt work because its eventually consistent meaning the write might not be immediately visible

P

pippin_mole•4/28/24, 6:47 PM

The runner would be on a cron every 10 minutes or so, EC wouldnt matter to me I dont think

P

pippin_mole•4/28/24, 6:47 PM

Please correct me if im wrong

U

Unsmart•4/28/24, 6:47 PM

Its 1 minute cache so yeah wouldnt be a problem but KV is more expensive so might as well use DO instead
