Console logs

Console messages logged in the page can be brought into 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
