hmm what exactly are you trying to do? I don't believe you can use the browser rendering binding in pages at all/not supported

V

villainyOP•4/18/24, 8:42 PM

Function that scrapes a website and use the data together with my api

V

villainyOP•4/18/24, 9:30 PM

what alternative do i have if it dosent work with pages?
create a dedicated worker api project , and then fetch it from my nextjs app?

J

James•4/18/24, 9:33 PM

browser rendering should work fine with

nodejs_compat

nodejs_compat

nodejs_compat

nodejs_compat if you do a bit of monkey patching

J

James•4/18/24, 9:33 PM

I have this in a worker:

import { Buffer } from 'node:buffer';
globalThis.Buffer = Buffer;

import puppeteer from '@cloudflare/puppeteer';

import { Buffer } from 'node:buffer';
globalThis.Buffer = Buffer;

import puppeteer from '@cloudflare/puppeteer';

import { Buffer } from 'node:buffer';
globalThis.Buffer = Buffer;

import puppeteer from '@cloudflare/puppeteer';

import { Buffer } from 'node:buffer';
globalThis.Buffer = Buffer;

import puppeteer from '@cloudflare/puppeteer';

J

James•4/18/24, 9:33 PM

with

compatibility_flags = [ "nodejs_compat" ]

compatibility_flags = [ "nodejs_compat" ]

compatibility_flags = [ "nodejs_compat" ]

compatibility_flags = [ "nodejs_compat" ]

J

James•4/18/24, 9:34 PM

and it does work, so in theory it should work in Pages too

J

James•4/18/24, 9:36 PM

you won't be able to test locally though

J

James•4/18/24, 9:36 PM

browser rendering doesn't work for local testing at all. And Pages doesn't have remote dev. So your only real way of testing would be to just deploy and see.

J

James•4/18/24, 9:36 PM

I think at this point I'd agree with your conclusion, and making a dedicated Worker API project and then just fetch that from app. That'll be much easier and give you so much better DX.

Its not private. If you have workers paid you can use it.

Hey all! Trying to use the "browser-rendering" feature to get the text of a page - the docs demo it at https://developers.cloudflare.com/browser-rendering/get-started/reuse-sessions/

but when I call
```
response.text
```
response.text
```
response.text
```
response.text
myself (copy/pasting the code from the docs), I get an error saying
```
Buffer is not defined
```
Buffer is not defined
```
Buffer is not defined
```
Buffer is not defined
- deep inside the CF Pupeteer package:

`

      at null.<anonymous>
  (file:///Users/josiahbryan/devel/rubber/cfworkers/browser-worker/node_modules/@cloudflare/puppeteer/src/common/HTTPResponse.ts:206:11)

Any suggestions on what I'm doing wrong...? Does

response.text()` just NOT work?

Usage is like:

const response = await page.goto(url, { waitUntil: 'networkidle2' });
// ...
const text = await response.text(); // <~--- "Buffer is not defined" error thrown here

const response = await page.goto(url, { waitUntil: 'networkidle2' });
// ...
const text = await response.text(); // <~--- "Buffer is not defined" error thrown here

const response = await page.goto(url, { waitUntil: 'networkidle2' });
// ...
const text = await response.text(); // <~--- "Buffer is not defined" error thrown here

const response = await page.goto(url, { waitUntil: 'networkidle2' });

globalThis.buffer as done above? Like:

globalThis.Buffer = Buffer;

Unsmart•4/24/24, 1:49 AM

Not really sure never used browser rendering, not having the compat flag seemed like the obvious culprit from the error message

J

Josiah Bryan•4/24/24, 2:31 AM

Yep - seems obvious, but the RENDERING works fine! Screenshot is gucci and nice. it's the ".text()" thing that is the problem
