Yea, CPU Time doesn't include time you're waiting on responses from fetch requests, CPU isn't active

Awesome, thank you!

https://developers.cloudflare.com/workers/runtime-apis/webassembly/javascript/#bundling

The documentation says we can import wasm binaries ending with .wasm.wasm or .wasm?module.wasm?module

But when I import using .wasm?module.wasm?module, it doesn't get resolved and throws exceptions.

Is there any mistake in documentation or am I doing anything wrong?

Wasm in JavaScript · Cloudflare Workers docs

Wasm can be used from within a Worker written in JavaScript or TypeScript by importing a Wasm module, and instantiating an instance of this module …

Deo Kumar•1/6/24, 4:30 AM

Or do I need to add rulesrules for it in

wrangler.toml

wrangler.toml

file

Deo Kumar•1/6/24, 4:32 AM

In the documentation:

This is done using a ~default bundling~ rule which can be customized in wrangler.toml

is there a recommended way to handle multiple routes for a worker?
i'm trying to map out an integration i'm working on and not sure if it needs to be 1 worker per URL, or 1 worker per "area" (eg: auth, sales, webhooks), or can be 1 monolith worker - are there any limitations that might steer me to look a certain way?

Erisa•1/6/24, 8:10 PM

You can honestly do any of those approaches.
1 worker per URL: assign them routes like domain.com/thisthingdomain.com/thisthing
1 worker per area: assign them routes like domain.com/auth/*domain.com/auth/*
1 monolith worker: assign them routes like domain.com/*domain.com/* or a worker custom domain

so it just depends on what makes the most sense for the dev flow that you want, and you can even have the workers communicate with each other over Service Bindings if need be (https://developers.cloudflare.com/workers/runtime-apis/service-bindings/#service-bindings)

Erisa•1/6/24, 8:11 PM

I suppose Workers for each route/path may be harder to develop unless theyre separate components that dont need to interact as a whole

rec•1/6/24, 8:22 PM

the monolith approach seems to be the sanest approach (well, until it's not)

i'm not too familiar with JS for server stuff, but is there any recommended approach to routing various endpoints for a worker? historically if i've needed an api written in js i'd just use express, but not even sure if that is an option for workers and if i google "cloudflare workers routing example" it doesn't seem to pull up what i'm looking for

https://hono.dev/

Hono is a small, simple, and ultrafast web framework for the Edges. It works on Cloudflare Workers, Fastly Compute, Deno, Bun, Vercel, Netlify, Lagon, AWS Lambda, Lambda@Edge, and Node.js. Fast, but not only fast.

kian•1/6/24, 8:22 PM

The closest to Express, written for serverless runtimes.

kian•1/6/24, 8:23 PM

It supports chained routes, grouping, etc

rec•1/6/24, 8:25 PM

awesome

Astro's local development story with Cloudflare is pretty dang good these days

Learn how to use the @astrojs/cloudflare SSR adapter to deploy your Astro project.

James•1/6/24, 8:34 PM

Their adapter adds supported bits of the cf runtime so you can get all the benefits of astro devastro dev with hmr, etc., but still use Cloudflare features like KV, D1, etc.: https://docs.astro.build/en/guides/integrations-guide/cloudflare/#cloudflare-runtime

James•1/6/24, 8:34 PM

It doesn't support everything yet, but supports the most popular bindings

Does anyone know how python integration using WASM works on Cloudflare Workers?

kian•1/6/24, 9:01 PM

The Workers template uses Transcrypt, so it's not WASM. There's work being done on the runtime to integrate https://pyodide.org/en/stable/ but you'd be on your own with trying to get that working.

araeyn:=Ψ∴∀t∈[0,t†](dΨ/dt<0∧Ψ→0)•1/6/24, 9:02 PM

ok, so right now is there no possible way to run python within cloudflare workers for responses?

kian•1/6/24, 9:03 PM

I haven't tried it, so it may be possible, but I haven't seen anyone else do it.

I've added compatibility_flags = [ "nodejs_compat" ]compatibility_flags = [ "nodejs_compat" ] to my wrangler.toml file but the TS server keeps giving this error:

daniel•1/6/24, 11:42 PM

anyone know a fix?

Original message was deleted

daniel•1/6/24, 11:47 PM

yeah i tried this earlier & restarted the ts server. same error

daniel•1/6/24, 11:50 PM

oh that works thanks

Jay•1/7/24, 8:33 AM

I'm trying to dynamically import something in my CF worker, which works when I do:

await import('path/to/file')

await import('path/to/file')

but whenever I do something like:

const file = 'test.js'
await import(`path/to/${file}`)

const file = 'test.js'
await import(`path/to/${file}`)

I get the error:

No such module \"path/to/test.js\".

No such module \"path/to/test.js\".

Jay•1/7/24, 8:34 AM

Anyone know if this is possible?

Jay•1/7/24, 8:36 AM

This question was asked once before here:

Jay•1/7/24, 8:36 AM

But honestly I'm not sure how to just 'tell Wrangler' based off the response (and link describing bundling) -- if they were referring to using rulesrules in my wrangler.toml, I did try that and it didn't seem to work either

kian•1/7/24, 3:51 PM

Nope

kian•1/7/24, 4:17 PM

If you're referring to unable to launch cloudflare website gulp: not found, it just means it isn't installed.

kian•1/7/24, 4:22 PM

How are you installing gulp? It needs to be installed in the build container, not on your machine.

Socal•1/8/24, 1:56 AM

What is the best way to throttle api to another rest api endpoint in a worker? The rest end point has a 60 requests/sec hard stop

Beyondo•1/8/24, 4:40 AM

Is there an official way to rate-limit a backend endpoint in Cloudflare, for example, a login endpoint that runs through a worker?

Beyondo•1/8/24, 6:23 AM

nevermind, just found out about WAF.

Beyondo•1/8/24, 6:54 AM

I just love cloudflare... everything's just there. Had I was still using firebase, I'd easily get from bruteforce attacks to billing fraud on all of my cloud functions. No such fear with WAF anymore lol.

McSneaky•1/8/24, 10:14 AM

Most likely nope, but asking over
Will worker-to-worker service binding end up in CloudFlare logs?

kian•1/8/24, 10:22 AM

It already shows up in the Workers live logs.

Mitya•1/8/24, 10:49 AM

I workers-and-pages-helpIs it possible to get Wrangler to reference source file names, not compiled ones, when error'ing? this in #workers-help but didn't get any joy: is it possible to get Wrangler to reference local, unminified files when reporting errors? Right now it reports errors relative to compiled files i.e. /.wrangler/tmp/dev-BjjrCX/index.js/.wrangler/tmp/dev-BjjrCX/index.js not my/original/file.jsmy/original/file.js? I've tried adding minify=trueminify=true to my TOML (both at the top, and under [vars][vars]) but the result is the same.
