attach to previously opened puppeteer driver

问题

Is it possible to reattach to an existing puppeteer ?

1. open puppeteer chrome browser.
2. node script ends without closing browser.
3. new script attaches and continue with the same browser.

For those who stumble upon this, here's an example of how I've got it working:

const puppeteer = require('puppeteer');

puppeteer.connect({"browserWSEndpoint" : "ws://some_string"}).then(async browser => {
    console.log("bla bla");
    ...
});

The browser.wsEndpoint you can find from the previous session:

const endpoint = browser.wsEndpoint();

Browser websocket endpoint which can be used as an argument to puppeteer.connect.
