What is headless mode in puppeteer?

React along with other framework like angular and vue. js are traditional client side framework ,they run in browser but there are technology to run this framework on server side, and next.

To use Puppeteer with a different version of Chrome or Chromium, pass in the executable’s path when creating a Browser instance: const browser = await puppeteer. launch({ executablePath: ‘/path/to/Chrome’ }); You can also use Puppeteer with Firefox Nightly (experimental support).

js application runs on the client-side (in the browser). Puppeteer cannot run inside that environment as you cannot start a full browser inside the browser.6 Mar 2019
