You can use the same session for multiple tasks like crawling multiple URLs. But if you want to do things in parallel, you just create new concurrent sessions. It's like running a Browser and doing the tasks or Multiple Browsers at the same time and performing multiple task in each one at the same time. Hope I was clear enough

Yep, I think I understand.

And I think it means that it's not going to have the worker-level scalability that I hoped it would. At least not without costing a fortune. Thanks for the information!

Does this API work in dev? I'm not seeing any indication that it shouldn't but when calling a method that works in prod I'm getting

Could not start browser instance. Error: TypeError: Cannot read properties of undefined (reading 'fetch')

Hey! You can use DOs, regardless of using one session or multiple concurrent sessions. Basically, using DOs allows you to reuse the same session by keeping it open longer, thus if you don't have the need to crawl or execute commands in parallel, one session should be enough. If you have the need to execute commands in parallel, then you can open new "concurrent" sessions

I just got access to the browser rendering API and I can't seem to get it to work. The response from puppeteer.launch(...) is null and I see a "Unabled to create new browser: code: 429: message: Too many browsers already running". I am running just this one instance for testing, is the system currently overloaded?

Wang•2/27/24, 2:16 AM

When I use local Node.js Puppeteer to access the website https://help.openai.com/en/articles/7102672-how-can-i-access-gpt-4, all content can be fully loaded. However, when using Cloudflare Browser Render to access it, not all content can be loaded, only some JavaScript scripts. What could be the reason for this?

W

Wang•2/27/24, 2:17 AM

This the local Node.js Puppeteer code:

const browser = await puppeteer.launch({headless: false});
const page = await browser.newPage();
const url = "https://help.openai.com/en/articles/7102672-how-can-i-access-gpt-4";
await page.goto(url, { waitUntil: 'networkidle0' }); // Ensure page is fully loaded

const content = await page.content();
console.log(content);

await browser.close();

const browser = await puppeteer.launch({headless: false});
const page = await browser.newPage();
const url = "https://help.openai.com/en/articles/7102672-how-can-i-access-gpt-4";
await page.goto(url, { waitUntil: 'networkidle0' }); // Ensure page is fully loaded

const content = await page.content();
console.log(content);

await browser.close();

const browser = await puppeteer.launch({headless: false});
const page = await browser.newPage();
const url = "https://help.openai.com/en/articles/7102672-how-can-i-access-gpt-4";
await page.goto(url, { waitUntil: 'networkidle0' }); // Ensure page is fully loaded

const content = await page.content();
console.log(content);

await browser.close();

const browser = await puppeteer.launch({headless: false});
const page = await browser.newPage();
const url = "https://help.openai.com/en/articles/7102672-how-can-i-access-gpt-4";
await page.goto(url, { waitUntil: 'networkidle0' }); // Ensure page is fully loaded

const content = await page.content();
console.log(content);

await browser.close();

Wang•2/27/24, 2:19 AM

This the worker code

const browser = await puppeteer.launch(env.MYBROWSER);
const page = await browser.newPage();
await page.goto(url, { waitUntil: 'networkidle0' }); // Ensure page is fully loaded

const content = await page.content();
console.log(content);
await browser.close();

const browser = await puppeteer.launch(env.MYBROWSER);
const page = await browser.newPage();
await page.goto(url, { waitUntil: 'networkidle0' }); // Ensure page is fully loaded

const content = await page.content();
console.log(content);
await browser.close();

const browser = await puppeteer.launch(env.MYBROWSER);
const page = await browser.newPage();
await page.goto(url, { waitUntil: 'networkidle0' }); // Ensure page is fully loaded

const content = await page.content();
console.log(content);
await browser.close();

const browser = await puppeteer.launch(env.MYBROWSER);

It's unlikely that you are going to be able to, or at least find support here for how to. You have to convince reCaptcha, that you aren't a bot... but since you are, you might have a hard time doing that.

jasonOP•3/5/24, 4:02 PM

Once you start a session, the browser remains in that location until it's closed. Your cannot move the browser to different locations. I'd imagine that the browser is opened in a location close to the request that it was opened; though I don't know that for sure.

hey did you ever make some progress on this? i'm doing the same thing for my app.... using 3JS to render some 3D and was even considering setting up my own GPU servers around the US to do my own "edge" rendering.... but would prefer to use cloudflare instead. but, in my research so far the WebGPU support and the browser rendering both don't really have a "real-time 3D rendering" feature as far as i can tell.....
