How do I handle scraping pages with endless AJAX requests?
Watching network requests in the browser’s dev tools usually reveals AJAX endpoints. Directly calling these endpoints is often more efficient.

I use Playwright or Puppeteer to handle cases where AJAX loads new data as I scroll, simulating user interaction and loading all data at once.

Scrapy’s Splash library renders JavaScript, making it easier to handle pages that rely heavily on AJAX for content.
-
Setting up intervals to wait between requests prevents missing data, especially when data loads incrementally.

I identify the JSON or XML responses of AJAX calls to pull out data directly, avoiding the need to render the entire page.

Tools like Selenium can trigger AJAX requests by interacting with the page, like clicking “load more” buttons, to display additional data.

Inspecting the URL structure of AJAX requests often reveals pagination parameters, which I can modify to control data retrieval directly.

Sometimes, lowering the scroll speed allows AJAX calls to complete and avoids missing dynamically loaded content.
