Chrome opens with a new default account
Hi,
Great project! I think it might be used by many people, hope you will continue working on it!
First when I ran node index.js <groupid> | tee permalinks.csv I got Error: Cannot find module 'chrome-launcher', so I installed chrome-launcher with npm install chrome-launcher.
Now what happens is that Chrome opens with a new default account, so I'm not logged in in FB anymore, so I can't scrape. Do you know how to fix it?
P.S.
While Graph API is a useful thing, you can only use it if you have the group token, which is often not the case...
Switch to Graph API
What this script does with puppeteer can be easily achieved way more easily using the facebook Graph API.

MutationObserver rocks
const target = document.querySelector('[aria-label="News Feed"]');
const observer = new MutationObserver((records) => console.log(records));
observer.observe(target, {childList: true});await page.evaluate(() => {
const observer = new MutationObserver(
function() {
// communicate with node through console.log method
console.log('__mutation')
}
)
const config = {
attributes: true,
childList: true,
characterData: true,
subtree: true
}
observer.observe(target, config)
})page.on('console', async (msg) => {
if (msg.text === '__mutation') {
// do something...
}
})Run fail in window10
