ConsoleMessage

ConsoleMessage objects are dispatched by page via the Page.Console event. For each console message logged in the page there will be corresponding event in the Playwright context.

// Listen for all console messages and print them to the standard output.
page.Console += (_, msg) => Console.WriteLine(msg.Text);

// Listen for all console messages and print errors to the standard output.
page.Console += (_, msg) =>
{
    if ("error".Equals(msg.Type))
        Console.WriteLine("Error text: " + msg.Text);
};

// Get the next console message
var waitForMessageTask = page.WaitForConsoleMessageAsync();
await page.EvaluateAsync("console.log('hello', 42, { foo: 'bar' });");
var message = await waitForMessageTask;
// Deconstruct console.log arguments
await message.Args.ElementAt(0).JsonValueAsync<string>(); // hello
await message.Args.ElementAt(1).JsonValueAsync<int>(); // 42
