Puppeteer log inside page.evaluate

Question

How can I console.log something inside the page.evaluate, passing it to node and using it during the evaluation of the page?

I actually want to log

Answer 1

I am trying to share my workaround if it helps anybody in future.

1. Print all the console outputs to stdout including warning, error, log:

   page = await browser.newPage();
   page.on("console", (consoleObj) => console.log(consoleObj.text()));
   

2. Print everything except warning:

   page.on('console', consoleObj => {
       if (consoleObj.type() !== 'warning') {
           console.log(consoleObj.text());
       }
   })
   

3. Print only logs (Ex: console.logs).

   page.on('console', consoleObj => {
       if (consoleObj.type() === 'log') {
           console.log(consoleObj.text());
       }
   })
   

The last one helped me more to debug efficiently.
