React 18/19 Original → API-Parity Svelte 5 Port
at a glance.
react-json-view-lite for Svelte 5: keep its familiar props, themes, and keyboard navigation in a runes-native port with typed snippets and SSR-safe IDs.
side-by-side.
Every surface that matters, compared without spin.
| feature | @humanspeak/svelte-json-view-lite | react-json-view-lite |
|---|---|---|
| Framework Runtime Separate native implementations; the Svelte port does not ship React. | Svelte 5 | React 18/19 |
| JsonView API data, style, shouldExpandNode, clickToExpandNode, compactTopLevel, and beforeExpandChange retain their names and purpose. | Same component + core props | Original API |
| Theme API The built-in theme exports and StyleProps surface port directly. | Same style-map shape | defaultStyles + darkStyles |
| Expand Strategies Existing expansion logic can move across without a new mental model. | Same helpers | allExpanded + collapseAllNested |
| Keyboard Navigation Both support arrow-key navigation through expandable nodes. | WAI-ARIA treeview | WAI-ARIA treeview |
| TypeScript Support | yes | yes |
| Per-type Rendering The Svelte port adds overrides for labels and every primitive value type. | 9 typed Svelte snippets | no |
| SSR-safe ARIA IDs Each implementation uses its framework-native stable-id primitive. | Svelte $props.id() | React useId |
| CSS Variable Overrides The Svelte port layers --sjv-* custom properties onto the familiar style map. | yes | no |
| Zero Runtime Dependencies | yes | yes |
| JSON Editing | no | no |
where each shines.
- +Same JsonView component name and core prop names
- +Same defaultStyles, darkStyles, allExpanded, and collapseAllNested exports
- +Svelte 5 runes-native implementation with no React compatibility layer
- +Typed Svelte snippet overrides for primitive values and labels
- +SSR-safe ids through $props.id()
- +WAI-ARIA tree semantics with keyboard navigation
- +Light and dark themes with CSS-variable overrides
- +Zero runtime dependencies
- +Original project and source of the shared API
- +Established package for React applications
- +React 18/19-native implementation
- +Accessible tree navigation with zero runtime dependencies
where each falls short.
- −Focused on viewing, not editing
- −No virtualization for very large JSON documents
- −Smaller ecosystem than older React JSON viewers
- −Requires React 18 or 19
- −Cannot render as a native Svelte component
- −No typed Svelte snippet overrides
- −No --sjv-* CSS-variable override layer
the honest call.
Stay with react-json-view-lite in a React 18 or 19 application. When moving to Svelte 5, switch the package import and component syntax, keep the familiar props, theme maps, and expansion helpers, then opt into typed snippets where useful. The migration is mechanical because this port deliberately preserves the upstream API shape.
