Update for puppeteer 12, adapted from the current documentation:
page.on('console', async (msg) => {
const msgArgs = msg.args();
for (let i = 0; i < msgArgs.length; ++i) {
console.log(await msgArgs[i].jsonValue());
}
});
await page.evaluate(() => console.log('hello', 5));
await page.evaluate(() => console.log({ foo: 'bar' }));
await page.evaluate(() => console.log([1, 2, 3, 4, 5]));
Shows the following results:
hello
5
{ foo: 'bar' }
[ 1, 2, 3, 4, 5 ]
