get the console results (objects ) with Puppeteer

Question

I'm having a problem getting the data from a site already exist on the console log on the devoloper tool. I'm new to Puppeteer so I'm trying to get all these console logs results but all of them have a string type. can you guys help me to find a way to get the real object or a way to parse it and use it, thanks

Please add more information about what you need to get, with examples, please. It's not clear currently what you mean. Do you want to get data that sites send to `console.log`? Do you want to get some global window objects that exist on the page and you can `console.log` and see them? — Vaviloff, Oct 26 '20 at 07:38

We use this to capture console events and log in node:

    page.on('console', async msg => {
      const args = msg.args();
      const vals = [];
      for (let i = 0; i < args.length; i++) {
        vals.push(await args[i].jsonValue());
      }
      console.log(vals.map(v => typeof v === 'object' ? JSON.stringify(v, null, 2) : v).join('\t'));
    });

It checks the type of message being logged and runs JSON.stringify if it is an object.
