# Svelte JSON View Lite vs @zerodevx/svelte-json-view Two Svelte 5 Viewers · Minimal Props or Typed Snippets ## Overview Compare @zerodevx/svelte-json-view with Svelte JSON View Lite: Svelte 5 runes, typed snippets, keyboard navigation, depth controls, and vanilla-JS support. - **Svelte JSON View Lite site:** https://jsonview.svelte.page - **Svelte JSON View Lite npm:** https://www.npmjs.com/package/%40humanspeak%2Fsvelte-json-view-lite - **Svelte JSON View Lite slug:** svelte-json-view-lite - **Category:** Direct Svelte alternative - **Approach:** Svelte 5 read-only viewer with an optional standalone JavaScript bundle - **Website:** https://github.com/zerodevx/svelte-json-view - **GitHub:** https://github.com/zerodevx/svelte-json-view - **npm:** https://www.npmjs.com/package/%40zerodevx%2Fsvelte-json-view ## Feature comparison | Feature | @humanspeak/svelte-json-view-lite | @zerodevx/svelte-json-view | Notes | | --- | --- | --- | --- | | 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 | shouldExpandNode(level, value, field) | Numeric depth prop | Both expand all nodes by default. In zerodevx, depth={0} leaves the root expanded and collapses nested containers. | | Expansion Veto Callback | beforeExpandChange | No | | | Snippet Overrides | 9 typed value and label snippets | No | The zerodevx public API exposes json and depth, with no custom-renderer prop. | | Keyboard Navigation | Arrow keys, roving tabindex, Enter/Space | Tab to brackets; Enter/Space to toggle | Both support keyboard interaction; their navigation models differ. | | ARIA Tree Semantics | Tree roles and expansion state | Lists and bracket buttons | The inspected zerodevx 2.0.0 component has no tree roles or aria-expanded. This comparison is not an accessibility certification. | | TypeScript Support | Yes | Yes | | | Standalone Vanilla-JS Bundle | No | createJsonView, update, destroy | zerodevx also documents CDN usage; our package is a Svelte component. | | JSON Editing | No | No | | | Virtualization | No | No | | ## Svelte JSON View Lite strengths - 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 ## @zerodevx/svelte-json-view strengths - 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 ## Svelte JSON View Lite limitations - 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 ## @zerodevx/svelte-json-view limitations - 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 ## Verdict 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. ## Keywords @zerodevx/svelte-json-view, zerodevx json view, zerodevx svelte-json-view alternative, svelte json viewer comparison
