Summary

Loaders are mechanisms for data loading. There are some tips on how to optimize their usage. Here are some tips:
  1. When the loader is reused in different sections or pages, it is recommended to use a saved loader (reusable)
  2. Sections that load data and are not displayed on the initial screen (above the fold) can be deferred

Reusing Loaders

The system’s sections can have data loaded via loaders. These loaders can be defined within the section itself or loaded from saved entities. These saved entities can be created from loader blocks. Creating a loader When saving a loader, it is guaranteed to be reusable in different sections. In addition to allowing props to be changed and reflected in all places where this loader is used, using this saved loader allows for optimizing the system’s usage. During a page like the Product Description Page (PDP), it is necessary to load information about the product twice: once for SEO details loading and once for displaying the product itself. By using the same loader, Deco optimizes it so that the loader is executed only once during the page rendering cycle. image
