Fetch Node

This section assumes you've already set up a unified Node model as described in Modeling Node — the fetch pattern below relies on being able to check whether NodeFields is already populated.

Cache pattern

To avoid fetching the entire node every time it is opened:

1. Check if NodeFields is already present (not null) in your local model.
2. If it is missing, trigger a fetch for the NodeDetailView.
3. If it is already present, safely reuse your cached data.

Concrete example

• Node tree — fetch light NodeView objects. You don't need the heavy NodeFields to build a tree.
• Opening a node — if NodeFields is absent, fetch the NodeDetailView; otherwise, display from cache.
