ngx-json-viewer

Angular component for displaying JSON data in a collapsible, tree-like view. Current stable version is 3.2.1, released periodically. Key differentiators: fully Angular-native (no jQuery), supports theming via CSS variables, configurable depth and initial expansion, works with Angular 2+. Older versions (v1 for Angular 2, v2 for Angular 4-7) have different APIs and are in maintenance mode.
