Two Svelte 5 Viewers · Minimal Props or Typed Snippets
at a glance.
Compare @zerodevx/svelte-json-view with Svelte JSON View Lite: Svelte 5 runes, typed snippets, keyboard navigation, depth controls, and vanilla-JS support.
side-by-side.
Every surface that matters, compared without spin.
| feature | @humanspeak/svelte-json-view-lite | @zerodevx/svelte-json-view |
|---|---|---|
| Svelte 5 Native | yes | yes |
| Read-only Tree View | yes | yes |
| Zero Runtime Dependencies | yes | yes |
| Theme Customization | yes | yes |
| CSS Variable Overrides | --sjv-* variables + style maps | Ten --json* variables |
| Expansion Policy Both expand all nodes by default. In zerodevx, depth={0} leaves the root expanded and collapses nested containers. | shouldExpandNode(level, value, field) | Numeric depth prop |
| Expansion Veto Callback | beforeExpandChange | no |
| Snippet Overrides The zerodevx public API exposes json and depth, with no custom-renderer prop. | 9 typed value and label snippets | no |
| Keyboard Navigation Both support keyboard interaction; their navigation models differ. | Arrow keys, roving tabindex, Enter/Space | Tab to brackets; Enter/Space to toggle |
| ARIA Tree Semantics The inspected zerodevx 2.0.0 component has no tree roles or aria-expanded. This comparison is not an accessibility certification. | Tree roles and expansion state | Lists and bracket buttons |
| TypeScript Support | yes | yes |
| Standalone Vanilla-JS Bundle zerodevx also documents CDN usage; our package is a Svelte component. | no | createJsonView, update, destroy |
| JSON Editing | no | no |
| Virtualization | no | no |
where each shines.
- +Typed snippets for primitive values and field labels
- +Tree roles, expansion state, and arrow-key navigation with roving tabindex
- +Expansion policies can inspect level, value, and field name
- +beforeExpandChange can veto a toggle
- +Familiar react-json-view-lite API and built-in light/dark style maps
- +Small public API: json and depth
- +Svelte 5 runes-native implementation
- +Standalone JavaScript bundle with update and destroy methods
- +CSS-variable theming and zero runtime dependencies
- +Svelte 4 and earlier users can stay on the v1 release line
where each falls short.
- −No standalone vanilla-JS or CDN widget API
- −Requires Svelte 5; no Svelte 4 compatibility
- −More configuration choices than a two-prop viewer
- −No editing or virtualization
- −No public snippet or custom-renderer API
- −No field-aware expansion policy or expansion veto callback
- −No arrow-key tree navigation, tree roles, or aria-expanded in 2.0.0
- −No editing or virtualization
the honest call.
Choose @zerodevx/svelte-json-view for a minimal json/depth interface or a standalone vanilla-JS widget. Choose Svelte JSON View Lite when typed snippets, tree keyboard navigation, expansion callbacks, or react-json-view-lite API familiarity matter. Both use Svelte 5 runes and have zero runtime dependencies; no speed or bundle-size advantage is claimed here. To migrate basic usage, change the import and rename json to data. Map depth={d} to shouldExpandNode={(level) => level <= d} for the initial expansion threshold, then adapt CSS variable names and verify dynamic expansion behavior.
