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.

Sync

# Listen for all console logs
page.on("console", lambda msg: print(msg.text))

# Listen for all console events and handle errors
page.on("console", lambda msg: print(f"error: {msg.text}") if msg.type == "error" else None)

# Get the next console log
with page.expect_console_message() as msg_info:
    # Issue console.log inside the page
    page.evaluate("console.log('hello', 42, { foo: 'bar' })")
msg = msg_info.value

# Deconstruct print arguments
msg.args[0].json_value() # hello
msg.args[1].json_value() # 42
