Data Anywhere with Pipelines, Event Notifications, and Workflows

We’re making it easier to build scalable, reliable, data-driven applications on top of our global network, and so we’re announcing a new Event Notifications framework; our take on durable execution, Workflows; and an upcoming streaming ingestion service, Pipelines

Did you figure this out?

Leo_C•9/20/24, 2:40 AM

Has anyone encountered this error: Route pattern must include your zone? I am sure that my route includes my zone, everything is the same as usual. It seems like the system has updated something, and the page UI is also different from before. I'm not entirely sure if this is the reason for the bug.

SSZAGLAM Is it possible to set up mTLS between two workers?

Did you manage to do mTLS between 2 workers?

Bram Roets•9/20/24, 7:19 AM

Has anyone experienced a situation where Cloudflare Workers Metrics show “Worker threw exception,” but the logs pushed by Logpush don’t contain any errors? I’m having trouble debugging this issue and would appreciate any insights.

My origin server is cloudflare worker itself, and using D1 inside it

Jadugar_Jaggu•9/20/24, 9:12 AM

so Technically there was may be some issue with workers , now it's working fine

o7•9/20/24, 10:10 AM

subrequest limit for paid workers is 1000.. what about cron triggers? Still 1000? or can we go above that

laurmat•9/20/24, 11:22 AM

Did you make it work? I’m trying to create mTLS between two workers, but it seems the cert is not present on the sender worker, even if I did all the steps in their guide.

ac•9/20/24, 1:27 PM

I can't load the new Settings tab for one of my workers, I just get this every time. Any tips?

Walshy•9/20/24, 2:02 PM

The team is aware and working on it!

LordSilver•9/20/24, 2:09 PM

What is the Browser Rendering API ? I read all the docs and example and still couldn't figure out.

LordSilver•9/20/24, 2:10 PM

There's no such thing in AWS, I just run Playwright inside a Lambda function and it just works. I don't think you need any kind of special API, and I don't actually see this kind of API, I just see examples of running Puppeteer inside a Worker.

LordSilver•9/20/24, 2:12 PM

Also, how is the Cloudflare worker able to use the full Chromium? That's heavy af compared to this.

LordSilver•9/20/24, 2:27 PM

Advised memory is 1600MB, but a Cloudflare Worker has a limit of 128MB. In my tests with Lambda, the average memory usage is 500-900MB, so how is it even possible that Puppeteer runs fine in Worker?

dexter•9/20/24, 2:32 PM

Is there a way (maybe with wrangler.toml) to set a different subdomain.workers.dev than the Worker name? For example use the name "foo-worker" but with

foo.workers.dev

foo.workers.dev

as the domain?

Chaika•9/20/24, 2:34 PM

Don't think so, if you want any customization like that, Custom Domain is the answer

Chaika•9/20/24, 2:35 PM

because it's not running in the worker, your worker merely connects and proxies commands/etc to a puppeteer instance running externally on a cf machine. iirc they all still run in ORD unless that changed

LLordSilver There's no such thing in AWS, I just run Playwright inside a Lambda function and...

Chaika•9/20/24, 2:37 PM

I think you've mostly figured it out now, but yea Playwright indeed would be way too big in Worker's limits, Browser Rendering is Puppeteer but running on CF separate from your worker instance and using a modified puppeteer lib to make it all work, it only supports some stuff though. There is a channel for it #browser-rendering-api
Some more details in blog post https://blog.cloudflare.com/browser-rendering-open-beta/

LordSilver•9/20/24, 2:54 PM

What does ORD mean?

LordSilver•9/20/24, 2:54 PM

Are yo usaying that when using the puppeteer module specifically, Cloudflare would run the code in a separate machine from your worker?

LLordSilver What does ORD mean?

Hard@Work•9/20/24, 2:55 PM

https://where.durableobjects.live/colo/ORD

Where Durable Objects Live

Chicago, Illinois, United States (colo)

Tracking where Durable Objects are created, wherever you are in the world.

HHard@Work https://where.durableobjects.live/colo/ORD

LordSilver•9/20/24, 2:55 PM

The first example doesn't use DO.

LordSilver•9/20/24, 2:55 PM

They aren't mandatory to use this feature.

LLordSilver The first example doesn't use DO.

Hard@Work•9/20/24, 2:56 PM

I was referring to the fact that ORD means Chicago

Hard@Work•9/20/24, 2:56 PM

Not that it uses DOs

LordSilver•9/20/24, 2:57 PM

What if you use playwright instead of puppeteer? Then the worker is unable to understand that it has to run the code in the separate machine I guess?

LordSilver•9/20/24, 2:57 PM

Ah nvm, you cannot.

LordSilver•9/20/24, 2:58 PM

I've just noticed the lib isn't puppeteerpuppeteer but rather @cloudflare/puppeteer@cloudflare/puppeteer so a custom version.

LordSilver•9/20/24, 2:59 PM

Now I understand what's this "Browser Rendering API". Basically proxying all requests of the puppeteer agent to a different beefier machine.

CChaika I think you've mostly figured it out now, but yea Playwright indeed would be way...

LordSilver•9/20/24, 3:03 PM

Well, if you compare puppeteer-core with playwright-core, it's less than 1MB difference.

LLordSilver Well, if you compare [puppeteer-core](https://www.npmjs.com/package/puppeteer-co...

Chaika•9/20/24, 3:04 PM

neither of those include the core browser

CChaika neither of those include the core browser

LordSilver•9/20/24, 3:04 PM

Yeah, you import the browser, there's optimized one just for serverless.

LordSilver•9/20/24, 3:04 PM

And it shouldn't matter. The size of the browser would be the same.

LLordSilver And it shouldn't matter. The size of the browser would be the same.

Chaika•9/20/24, 3:05 PM

Workers size limits are 1 MB free 10 MB paid, is what I was referring to there

Chaika•9/20/24, 3:05 PM

trying to run either inside of the Worker itself wouldn't work

LordSilver•9/20/24, 3:05 PM

Yeah I know, Cloudflare would need to support it with their own custom module.

LordSilver•9/20/24, 3:06 PM

So you don't pay for any resource used by this separate machine that actually runs puppeteer?

Chaika•9/20/24, 3:07 PM

You will eventually, right now it's just

Browser Rendering is now available to all customers with a paid Workers plan. Each account is limited to running two new browsers per minute and two concurrent browsers at no cost during this period.

LordSilver•9/20/24, 3:07 PM

Ah, seemed too good to be true.

LordSilver•9/20/24, 3:08 PM

Two new browsers per minute, but what if you keep the browser open indefinitely with a DO?

LLordSilver Two new browsers per minute, but what if you keep the browser open indefinitely ...

Chaika•9/20/24, 3:09 PM

can't do indefinitely as eventually the DO will sleep/browser session will expire but using a DO with a queue/etc is one way around it yea

Chaika•9/20/24, 3:09 PM

https://developers.cloudflare.com/browser-rendering/get-started/browser-rendering-with-do/ there's a guide there for that

Cloudflare Docs

By following this guide, you will create a Worker that uses the Browser Rendering API along with Durable Objects to take screenshots from web pages and store them in R2.

LordSilver•9/20/24, 3:09 PM

There's a hard limit to how long DO can hang after a Worker finished?

LordSilver•9/20/24, 3:10 PM

The example in the docs uses 60s
