I am executing the command await browser.pages() in Pyppeteer and each time it runs, the browser windows resize to a very small dimension. Is there a solution to prevent this from happening? I need to assess each browser URL every second, and the tiny window size makes the browser unworkable. Interestingly, if I reposition the browser window, it restores to its full size. My implementation uses pyppeteer.connect.
async def main_function():
browser_instance = await pyppeteer.connect(browserURL='http://127.0.0.1:9222')
open_tabs = browser_instance.pages()
print(open_tabs)
index = 0
print(len(open_tabs))
while index < len(open_tabs):
print(await open_tabs[index].evaluate("() => window.location.href"))
index += 1
Additionally, are there simpler methods to retrieve all active URLs in my browser? Thank you!
To prevent the resizing issue, try setting a specific viewport size right after connecting to the browser. You should also await browser.pages() to work with the list of pages.
async def main_function():
browser_instance = await pyppeteer.connect(browserURL='http://127.0.0.1:9222')
open_tabs = await browser_instance.pages()
for page in open_tabs:
await page.setViewport({'width': 1366, 'height': 768})
print(await page.evaluate("() => window.location.href"))
This should keep the browser windows at your set dimensions. For retrieving URLs, the code snippet above is simple and direct. Hope this helps!
When dealing with Puppeteer, specifically using pyppeteer, ensuring the window maintains its intended dimensions is vital for usability, especially with minimizing issues like you have described. As ClimbingLion mentioned, setting the viewport, which determines the visible area of the browser content, helps manage this.
Expanding on this, if you find the resizing issue persists even after setting the viewport, consider these additional approaches:
- Disable Headless Mode: While headless mode is efficient, if you don't require it for your application, disabling it could resolve resizing challenges.
browser_instance = await pyppeteer.connect(
browserURL='http://127.0.0.1:9222',
headless=False
)
- Manual Resizing: While not ideal in production, if the dimensions must be changed dynamically, you can always programmatically resize the window:
await open_tab[index].setViewport({'width': window_width, 'height': window_height})
As for retrieving all active URLs and managing tabs efficiently, the script you’re using is quite straightforward and effectively lists the URLs of opened pages. If you are frequently performing this task, consider optimizing the retrieval frequency to manage resource usage effectively.
Experiment with these methods considering your actual application's context, and it should improve your workflow.
To address the window resizing issue in Pyppeteer, using browser.pages(), you should set the viewport size immediately after connecting to the browser. Await the pages() function to ensure you work with the complete list of pages. This can prevent undesired resizing:
async def main_function():
browser_instance = await pyppeteer.connect(browserURL='http://127.0.0.1:9222')
open_tabs = await browser_instance.pages()
for page in open_tabs:
await page.setViewport({'width': 1366, 'height': 768})
print(await page.evaluate("() => window.location.href"))
Additionally, if the issue persists, consider these optimizations:
- Disable Headless Mode: If visual verification isn't required, running in non-headless mode might prevent size issues:
browser_instance = await pyppeteer.connect(
browserURL='http://127.0.0.1:9222',
headless=False
)
- Programmatic Adjustment: Dynamically adjust the viewport if resizing occurs:
await page.setViewport({'width': desired_width, 'height': desired_height})
For frequent URL retrieval, your current approach is practical and allows for easy adjustment of how often URLs are checked, optimizing resource use.
Implementing these suggestions should enhance your workflow and maintain window size consistently. Good luck!
To stop the Pyppeteer browser window resizing, set the viewport size post connection:
async def main_function():
browser_instance = await pyppeteer.connect(browserURL='http://127.0.0.1:9222')
open_tabs = await browser_instance.pages()
for page in open_tabs:
await page.setViewport({'width': 1366, 'height': 768})
print(await page.evaluate("() => window.location.href"))
If resizing persists, disable headless mode:
browser_instance = await pyppeteer.connect(
browserURL='http://127.0.0.1:9222',
headless=False
)
Your current method for retrieving URLs is effective. Cheers!
If you're encountering persistent issues with the browser window resizing in Pyppeteer even after setting the viewport, there might be a few unconventional strategies worth considering to stabilize your configuration:
Another facet to explore could be incorporating session-specific viewport settings. Depending on your use case, managing sessions with predefined configurations might ease the complexity in maintaining uniformity across different windows.
For URL retrieval, consider implementing cached fetching mechanisms if real-time data is not critical. This will help in reducing the load on the browser, and concurrent timing issues might improve the reliability of window dimensions and performance.
Adopting these alternate approaches may provide a robust solution to the viewport challenges you're facing with Pyppeteer.
