ConsoleMessage

ConsoleMessage objects are dispatched by page via the page.on('console') event. For each console messages 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 [msg] = await Promise.all([
  page.waitForEvent('console'),
  // Issue console.log inside the page
  page.evaluate(() => {
    console.log('hello', 42, { foo: 'bar' });
  }),
]);

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