Hello!
I am a bit confused which product would best fit my use case.
Basically, I have a worker acting as a reverse proxy.
The goal is: keep it up to date with the latest config table which is on a remote gcloud database.
What i really want to do is to keep the internal (in memory) config up-to-date across all workers and propagate the remote db changes. What should i use to keep everything running smooth and cost effective with billions requests? I am testing D1 and cron triggers but not sure it's the best approach. Would appreciate some tips --- thanks!

I am sitting here reading about JavaScript-native RPC in workers...
https://blog.cloudflare.com/javascript-native-rpc

Do I understand this correctly:

I can create a worker, that exports a class extending

WorkerEntrypoint

WorkerEntrypoint

WorkerEntrypoint

WorkerEntrypoint .
This worker kan be added as a binding to other workers, and all the methods will be avaiable.
If I want to create more classes that I want the worker to export, i can create other classes that extend

RpcTarget

RpcTarget

. And return these from the

WorkerEntrypoint

WorkerEntrypoint

WorkerEntrypoint

WorkerEntrypoint class.

This way, i can create a whole app, and have it directly accessible from another worker, with no http.
If this EntryPoint worker is updated, it will update on all other workers that has it in its bindings

const botCategory = request.cf.verifiedBotCategory;
if (['search_engine_crawler', 'search_engine_optimization', 'page_preview'].includes(botCategory)) {
return fetch(request);
is this good way to write in worker to detect bot catagory?

Is there a cost associated to using cron triggers? Is it just a single worker request? Anything specific to the cron trigger itself?

Hi, I am using the new RPC service bindings and generally the binding seems to work. I can call a remote function and it returns the expected value. However when I checked the logs, it shows "outcome: canceled" for some reason. What is weird is that it seems to return properly nevertheless. Any ideas why it shows "canceled"?

J

johtso•4/6/24, 1:25 PM

I'm a bit confused about the logging limits with workers, how am I supposed to get observability if my logs are always truncated? and this applies even if I'm doing something like logpushing to baselime?

doesn't help that I'm using a library that does some noisy logging that I'm not sure if I can suppress..

FYI, if you're using VS Code and your prettier is failing to parse (TypeError) on the

using

using

keyword, just install a local dev version of prettier to that worker, i.e. -

npm install --save-dev --save-exact prettier

npm install --save-dev --save-exact prettier

npm install --save-dev --save-exact prettier

npm install --save-dev --save-exact prettier and the parser will prefer that version (which has had support for

using

since last year).

Tilon•4/6/24, 9:24 PM

when I import my WorkerEntrypoint

How/what are you importing in that case? are you importing the type? If so, that could be the issue maybe. It should just be a

service.d.ts

service.d.ts

service.d.ts

service.d.ts file for example that includes the types, not an import.

simplified my worker looks like this:

export default class MyService extends WorkerEntrypoint<Env> {
async fetch() {
return new Response("OK");
}

async doStuff() {}
}

and the in my other project I bind to the service and have a service.d.ts like so:

declare class MyService extends WorkerEntrypoint {
async doStuff(): Promise<void>;
}

and

interface Env {
MY_SERVICE: MyService;
}

but no import.

johtso•4/6/24, 9:29 PM

Code's in a monorepo, different workers different packages. I'm doing

import type { PdfParserService } from "pdfparser_service"

import type { PdfParserService } from "pdfparser_service"

import type { PdfParserService } from "pdfparser_service"

import type { PdfParserService } from "pdfparser_service" being my package that exports my worker definition

J

johtso•4/6/24, 9:30 PM

I don't have a

service.d.ts will give that a try.. didn't see any mention of that in the typescript section of the docs unless I missed it..

@Tilon hold up, why are you having to explicitly declare a type for

In my case it's not a monorepo. If I would have a monorepo, I would probably have tried as well what you did.

the docs also say to do something like

I basically did what's written in the blog post under "What about type safety"
https://blog.cloudflare.com/javascript-native-rpc

Hmm, I just read it again and it sounds like import should work as well:

You might do this by defining the interface in a separate shared TypeScript file, or by extracting a .d.ts type declaration file from your server code...

The Cloudflare Blog

We've added JavaScript-native RPC to Cloudflare Workers

Cloudflare Workers now features a built-in RPC (Remote Procedure Call) system for use in Worker-to-Worker and Worker-to-Durable Object communication, with absolutely minimal boilerplate. We've designed an RPC system so expressive that calling a remote service can feel like using a library.
