How on vue.js + webpack to load certain data later or on an event?

Question

webpack

There is a website with lots of photos and text.
The user may not even scroll to the end, so it makes no sense to load the data.
How to make sure that all the most necessary things are loaded first, and part of the data is loaded later.
Secondary data at the end is loaded at all when scrolling.
In general, the question is more about loading with webpack.
For example, on YouTube, I first see a tabular layout, and then a photo from the video, which speeds up the download.
