Use `wait_until='networkidle'` in the `page.goto()` method to ensure all network requests have finished before proceeding.
Set `wait_until='domcontentloaded'` to wait only for the HTML document to be fully loaded and parsed, which is faster when you don't need to wait for stylesheets, images, and subframes to finish loading.
Opt for `wait_until='load'` when you need to ensure that the whole page, including all dependent resources, is fully loaded.
Regularly update Playwright to leverage improvements and new features in handling page load strategies.
from playwright.sync_api import sync_playwright # Initialize Playwright and start a browser with sync_playwright() as p: browser = p.chromium.launch() page = browser.new_page() # Navigate to the URL and wait until network is idle page.goto('https://sandbox.oxylabs.io/products', wait_until='networkidle') # Alternative: wait until DOM is fully loaded page.goto('https://sandbox.oxylabs.io/products', wait_until='domcontentloaded') # Another method: wait until everything is loaded page.goto('https://sandbox.oxylabs.io/products', wait_until='load') # Perform actions or extract data # Example: print the page title print(page.title()) # Close the browser browser.close()
Ensure that your network conditions are stable and fast enough to avoid timeouts during page loads in Playwright.
Increase the default timeout in `page.goto()` if your application consistently takes longer to load, to prevent premature termination.
Utilize `page.wait_for_selector(selector)` to wait for specific elements to appear on the page, ensuring that dynamic content is fully loaded.
Check for any JavaScript errors in the console after page load that might indicate issues with complete page rendering.
