And so the recommended way to use this service is to keep browsers alive as much as possible with Durable Objects?

AFAIK yes, how the pricing works exactly is still a bit unclear, but it seems like there is little harm in keeping sessions open as long as possible to re-use them.

Let's say I'm generating PDF of tickets, and an event goes live, 10k people purchase a ticket. I put each ticketId in the queue which gets consumed by a worker which is calling this API via a DO

V

vassbence•10/15/23, 10:14 AM

but that means there is literally 1 consumer for the queue running 1 request / sec (or worse if it takes longer)

V

vassbence•10/15/23, 10:15 AM

Which would be really bad

V

vassbence•10/15/23, 10:15 AM

Or I can actually fan out the work to multiple browsers, it's jut that it's going to cost a lot more?

Z

zegevlier•10/15/23, 10:18 AM

You can absolutely do that: Keep in mind that the current limits for the beta only allow 2 concurrent browsers (https://developers.cloudflare.com/browser-rendering/platform/limits/), and the current pricing (from https://blog.cloudflare.com/running-serverless-puppeteer-workers-durable-objects/) means that fanning out will increase the cost by quite a lot.

V

vassbence•10/15/23, 10:19 AM

Yeah... so to keep using Cloudflare workers i'd need to write logic to fan out to a minimal amount of browsers but keep them 100% working all the time

V

vassbence•10/15/23, 10:20 AM

AWS Lambda is just a better solution for this currently, at least for my use case, as each lambda can start their own puppeteer, i can easily call 10k lambdas and the pricing is a lot better.

vassbence•10/16/23, 5:04 PM

how long does it take to spin up a new browser instance? I am running this code:

    const browser = await puppeteer.launch(env.BROWSER);
    const page = await browser.newPage();

    const [res] = await Promise.all([
        page.waitForResponse(res => res.url().includes('something') && res.request().method().toUpperCase() !== "OPTIONS", {timeout: 10 * 1000}),
        page.goto('https://someurl.com', {waitUntil: "domcontentloaded"}),
    ]);

    const browser = await puppeteer.launch(env.BROWSER);
    const page = await browser.newPage();

    const [res] = await Promise.all([
        page.waitForResponse(res => res.url().includes('something') && res.request().method().toUpperCase() !== "OPTIONS", {timeout: 10 * 1000}),
        page.goto('https://someurl.com', {waitUntil: "domcontentloaded"}),
    ]);

    const browser = await puppeteer.launch(env.BROWSER);
    const page = await browser.newPage();

    const [res] = await Promise.all([
        page.waitForResponse(res => res.url().includes('something') && res.request().method().toUpperCase() !== "OPTIONS", {timeout: 10 * 1000}),
        page.goto('https://someurl.com', {waitUntil: "domcontentloaded"}),
    ]);

    const browser = await puppeteer.launch(env.BROWSER);
    const page = await browser.newPage();

    const [res] = await Promise.all([
        page.waitForResponse(res => res.url().includes('something') && res.request().method().toUpperCase() !== "OPTIONS", {timeout: 10 * 1000}),
        page.goto('https://someurl.com', {waitUntil: "domcontentloaded"}),
    ]);

And locally, on my Mac, it takes 2-3 seconds in total. In Cloudflare however, it seems to be taking a lot longer perhaps? I don't really know, but it's getting exceeded resources and the log tail says CPU exceeded. It says for CPU, but again, I can't see how one request like this would use so much CPU... it's listed as using 75ms of CPU time, so I'm just really confused!

This makes it even more confusing

Varying CPU times, some exceeded, some not

Hey lovely CF people.. I am having a proper challenge building the Open Telemetry library and auto-instrumenting it, because you are implementing exactly the same interface as say a service binding (a

fetch

fetch

method), but at least in your documentation you instruct people to invoke that in a way that is not spec compliant.

This leads to two problems:
1) I can't (easily) distinguish between a ServiceBinding and a BrowserRendering Binding
2) When I try to create a

Request

Request

Request

Request out of the parameters you specify (

/v1/acquire

/v1/acquire

/v1/acquire

/v1/acquire) it (obviously) fails because

/v1/acquire

/v1/acquire

/v1/acquire

/v1/acquire is not a valid URL.

Now #2 can probably be easily solved by passing in a proper URL, but that would just prevent things from crashing.

Technically I could solve #1 by instrumenting any

fetch

fetch

function with a generic wrapper and then decide which instrumentation implementation to use based on the parameters passed into the

fetch

fetch

function, but that would be pretty brittle, because I would have to hardcode exactly what you would pass into the first request.

Erwin•10/24/23, 7:55 AM

The puppeteer library can easily add support for instrumentation by just using the OTel API functions. That will be picked up by this library and be automatically added.
