ConsoleMessage class overview
ConsoleMessage objects are dispatched by page via the event: Page.console event. For each console message logged in the page there will be a corresponding event in the Playwright context. ConsoleMessage has been available since v1.8.
ConsoleMessage example - listen for console logs in JavaScript
page.on('console', msg => console.log(msg.text()));
ConsoleMessage example - listen for console events and handle errors in JavaScript
page.on('console', msg => { if (msg.type() === 'error') console.log(`Error text: "${msg.text()}"`) });
ConsoleMessage example - get next console log and deconstruct arguments in JavaScript
const msgPromise = page.waitForEvent('console'); await page.evaluate(() => { console.log('hello', 42, { foo: 'bar' }); }); const msg = await msgPromise; await msg.args()[0].jsonValue(); // hello await msg.args()[1].jsonValue(); // 42
ConsoleMessage example - listen for console messages in Python
page.on("console", lambda msg: print(msg.text))
ConsoleMessage example - handle errors in Python
page.on("console", lambda msg: print(f"error: {msg.text}") if msg.type == "error" else None)
ConsoleMessage example - get next console log in Python async
async with page.expect_console_message() as msg_info: await page.evaluate("console.log('hello', 42, { foo: 'bar' })") msg = await msg_info.value await msg.args[0].json_value() # hello await msg.args[1].json_value() # 42

ConsoleMessage example - get next console message and deconstruct arguments in Java

ConsoleMessage example - get next console message and deconstruct arguments in C#
var waitForMessageTask = page.WaitForConsoleMessageAsync(); await page.EvaluateAsync("console.log('hello', 42, { foo: 'bar' });"); var message = await waitForMessageTask; await message.Args.ElementAt(0).JsonValueAsync<string>(); // hello await message.Args.ElementAt(1).JsonValueAsync<int>(); // 42
