ConsoleMessage | Playwright

ConsoleMessage objects are dispatched by page via the page.on(‘console’) event. For each console message logged in the page there will be corresponding event in the Playwright context.

    // Listen for all console logs
    page.on('console', msg => console.log(msg.text()));

    // Listen for all console events and handle errors
    page.on('console', msg => {
      if (msg.type() === 'error')
        console.log(`Error text: "${msg.text()}"`);
    });

    // Get the next console log
    const msgPromise = page.waitForEvent('console');
    await page.evaluate(() => {
      console.log('hello', 42, { foo: 'bar' });  // Issue console.log inside the page
    });
    const msg = await msgPromise;

    // Deconstruct console log arguments
    await msg.args()[0].jsonValue(); // hello
    await msg.args()[1].jsonValue(); // 42
