I have a collection of webpage addresses that I need to scrape for data. I organized these addresses into an array and attempted to process them as shown below:
const linkSet = ['siteA', 'siteB', 'siteC'];
(async function processLinks() {
for (const address of linkSet) {
await contextPage.navigateTo(address);
await contextPage.waitForSelector('body', { timeout: 7000 });
}
})();
The current implementation seems to navigate through each address too quickly, without ensuring that the page has fully loaded. I have tried different waiting methods, but the delay remains insufficient. Could I be missing a key detail in my approach, or is using such a looping mechanism with Puppeteer not recommended?
In practical experience, issues with page load timings using Puppeteer can often be traced to the specifics of how the page signals its readiness. Instead of simply waiting for the body element, I have found that leveraging Puppeteer’s network idle options such as waitForNavigation with the networkidle2 event can provide a more robust solution. This approach generally makes navigation less prone to timing issues, especially on pages with asynchronous elements. It is also important to implement additional handling for cases where unexpected delays occur, ensuring better resilience in scraping operations.
i ran into similar issues. try using page.goto(url, {waitUntil:‘networkidle2’}) instead. it gave more reliable results for me. sometimes a bit extra timeout on heavy js sites helps too. good luck!
Based on my experience, switching from a basic loop with waitForSelector to a more nuanced approach helped a lot. I encountered similar issues where pages with heavy JavaScript required more than just a single element check. I modified my code to use page.goto with a precise set of wait options and also inserted a slight manual delay using waitForTimeout to allow any asynchronous scripts to complete. Furthermore, breaking the process into smaller functions and wrapping navigation calls in try-catch blocks made my workflow more resilient by handling unexpected delays and failures gracefully.
