Main difference there is you sort of have to manage the load of the durable objects yourself a bit

J

James•11/15/23, 2:36 AM

In my opinion, any product that requires a user to scaffold something like a DO to manage things themselves to ensure their pricing doesn’t explode is a really bad design for serverless and the rest of Cloudflare’s product stack.

Z

zegevlier•11/15/23, 6:40 AM

This is my largest issue with the current pricing. For it to be at all competitive, you need to manage it state fully, which is so opposed to the rest of the product stack

Bram•11/15/23, 6:49 AM

How so? I thought a session can live a maximum of 60 seconds as a limit?

Bram•11/15/23, 6:50 AM

Ah wait, you have to keep it warm

They get killed after 60 seconds of inactivity

Bram•11/15/23, 6:50 AM

A browser instance gets killed if it does not get any command for 60 seconds, freeing one instance.

Maybe, or maybe not it seems. It depends if the DO gets reset or runs out of memory. That question is really what we've been asking since the pricing was announced. So, maybe, but probably not in real world production (at least not for months).

Which imo is weird for a cloud product, it should be cost optimised behind the scenes and have competitive per usage pricing imo, if you have a special use case that needs full control over the browser instance lifetimes, they could expose an additional API for lower level control?

Hi, let's say I want to set the html programitcally with

setContent and that html runs some javascript that wants to access a large local json file, can puppeteer somehow access the local filestystem of the worker? Or how would this work?

Bram•11/16/23, 10:30 AM

I ended up just embedding the large json directly into a script tag, not sure if it is the most efficient way, but it works

Ssc You can't access the local file system. You could save the file in R2 (they can ...

B

Bram•11/16/23, 11:23 AM

yea, in fact the json blob is inside r2 already, but it has to stay private, was thinking about using a signed url to generate temporary access, but was wondering if there was a better way. For now directly embedding it into the html (like so:

<script> const json = JSON.parse(${rawJson};  ...

<script> const json = JSON.parse(${rawJson}; ...

<script> const json = JSON.parse(${rawJson};  ...

<script> const json = JSON.parse(${rawJson}; ...) and then use

page.setContents

page.setContents

page.setContents

page.setContents works, but not sure if this is a performant way to do it.

It seems like the @\cloudflare/puppeteer npm package is not working entirely as intended as the regular puppeteer does - for example, taking a screenshot of a youtube page, 1st image is using puppeteer on my pc (same result when using a vps I have), and the 2nd image is puppeteer hosted using the browser rendering api on cloudflare using @\cloudflare/puppeteer npm package

For reference, I did use almost exactly the same code, the puppeteer one:

    const browser = await pup.launch({
        headless: `new`,
        defaultViewport: { width: 1920, height: 1080 },
    })

    const getPageSnapshot = (url, fullPage) => new Promise(async (resolve, reject) => { // this returns a promise resolving to a buffer
        const page = await browser.newPage().catch(reject)
        await page.goto(url).catch(reject)

        resolve(await page.screenshot({
            fullPage
        }).then(async (r) => { await page.close(); return r }).catch(reject))
    })

    const browser = await pup.launch({
        headless: `new`,
        defaultViewport: { width: 1920, height: 1080 },
    })

    const getPageSnapshot = (url, fullPage) => new Promise(async (resolve, reject) => { // this returns a promise resolving to a buffer
        const page = await browser.newPage().catch(reject)
        await page.goto(url).catch(reject)

        resolve(await page.screenshot({
            fullPage
        }).then(async (r) => { await page.close(); return r }).catch(reject))
    })

    const browser = await pup.launch({
        headless: `new`,
        defaultViewport: { width: 1920, height: 1080 },
    })

    const getPageSnapshot = (url, fullPage) => new Promise(async (resolve, reject) => { // this returns a promise resolving to a buffer
        const page = await browser.newPage().catch(reject)
        await page.goto(url).catch(reject)

        resolve(await page.screenshot({
            fullPage
        }).then(async (r) => { await page.close(); return r }).catch(reject))
    })

    const browser = await pup.launch({
        headless: `new`,
        defaultViewport: { width: 1920, height: 1080 },
    })

    const getPageSnapshot = (url, fullPage) => new Promise(async (resolve, reject) => { // this returns a promise resolving to a buffer
        const page = await browser.newPage().catch(reject)
        await page.goto(url).catch(reject)

        resolve(await page.screenshot({
            fullPage
        }).then(async (r) => { await page.close(); return r }).catch(reject))
    })

And the cloudflare one:
