Launch new tab instead of launch new browser

[vincent178]

Hi,

Thanks for the nice repo, it is very helpful. Just one issue:

app.all('*', async (request, response, next) => {
  response.locals.browser = await puppeteer.launch({
    dumpio: true,
    // headless: false,
    // executablePath: 'google-chrome',
    args: ['--no-sandbox', '--disable-setuid-sandbox'], // , '--disable-dev-shm-usage']
  });

  next(); // pass control on to routes.
});

This code shows that we create a new browser every time for a new request, this requires more memory and more load time than create a new tab for the same browser.

I wonder what's the thought behind this?

Thanks, Vincent

Generally it keeps things more ephemeral starting a new instance. Others have found the same: https://docs.browserless.io/blog/2018/06/04/puppeteer-best-practices.html

Puppeteer just introduce browser contexts for cases like this. The feature basically open Chrome in incognito tab but you can use the same browser instance to span across multiple contexts, yet keep cookie stores and session data separate.
