JSON Tree Viewer Architecture & DOM Virtualization

Visualizing deeply nested JSON payloads requires an intuitive, collapsible tree diagram capable of rendering thousands of nodes without browser lag.

1. Hierarchical Node Classification

Every node in the tree is labeled by its structural data type:

• Object: Collapsible container displaying total key count (e.g. object [5 keys]).
• Array: Collapsible list displaying element count (e.g. array [100 items]).
• Primitives: Color-coded string, number, boolean, and null badges.

2. Real-Time Tree Search & Filtering

The search engine traverses node keys and primitive values, automatically expanding parent paths containing query matches while dimming non-matching siblings.
