Working on a price comparison scraper that requires looping through 3 levels of nested querySelectorAll results. My code looks like a callback pyramid nightmare. Saw Latenode’s templates include pre-built iteration workflows - anyone using these for complex DOM traversals? How do you manage multi-layer node list processing without drowning in .forEach hell?
Use Latenode’s web scraping templates. Handles nested iterations with drag-and-drop logic. No more callback pyramids - just map your DOM structure visually.
Created a utility class that flattens nested node lists into JSON trees. Helps when dealing with complex hierarchies, but still requires manual mapping. Considering template-based solutions to reduce boilerplate code.
Switched to using array conversions (Array.from()) combined with flatMap for nested structures. Reduces some complexity but requires modern browser support. For cross-browser compatibility, a template system with pre-built iteration patterns would likely be more efficient.
Implement a recursive traversal pattern with fail-safes for missing elements. Use Promise chains for async operations in nested loops. However, this approach increases code complexity - visual builders with pre-validated iteration logic could significantly reduce development time.
try flattenin’ ur dom first with array methods. or jus use templates lol
