pyppeteer wait until all elements of page is loaded

I am using pyppeteer to trigger headless chrome and perform some actions. But first I want all the elements of the web page to load completely. The official documentation of pyppeteer suggests a waitUntil parameter which comes with more than 1 parameters.

My doubt is do i have to pass all the parameters or any one in particular is sufficient? Please suggest if following snippet helps in my case?

await page.goto(url, {'waitUntil' : ['load', 'domcontentloaded', 'networkidle0', 'networkidle2']})

No, you don't have to pass all possible options to 'waitUntil'. You can pick either of them, or more options at the same time if you like, but if you are:

  • not deailing with a single-page app,
  • not interested in all network connections (like 3rd party trackings for example)

then you are good to go with: 'domcontentloaded' to wait for all the elements to be rendered on the page.

await page.goto(url, {'waitUntil' : 'domcontentloaded'})

The options in details:

  • load: when load event is fired.

  • domcontentloaded: when the DOMContentLoaded event is fired.

  • networkidle0: when there are no more than 0 network connections for at least 500 ms.

  • networkidle2: when there are no more than 2 network connections for at least 500 ms.

Note: of course it is true for the NodeJs puppeteer library as well, they work the same way in terms of waitUntil.
