* feat: add custom directives API and @json-render/directives package
Add a `defineDirective` API that lets users register custom `$`-prefixed
dynamic values with schemas, resolvers, and prompt instructions — extending
the spec language without forking core.
* fixes
* perf(core): optimize findDirective to iterate registry instead of object keys
Flip the loop from O(object-keys) to O(registry-size) by iterating
the directive registry and checking `key in value` rather than scanning
all object keys with Object.keys() and startsWith("$").
* fix(core): reject directive names that conflict with built-in keys
defineDirective now throws at registration time if the name collides
with a built-in prop expression key ($state, $cond, etc.), making the
precedence contract explicit rather than relying on check ordering in
resolvePropValue.
* fix(directives): handle future dates in $format and warn on $math NaN coercion
$format relative dates now support future timestamps ("2h from now")
and return "just now" for zero diff. $math emits a console.warn in
dev mode when a non-numeric value is silently coerced to 0.
* fix(directives): remove process.env check that breaks DTS build
The directives package doesn't include @types/node, so referencing
process.env fails during tsup's DTS generation. The console.warn is
unconditional now — it only fires on actual misuse (non-numeric input)
so the cost is negligible.
* feat(directives): rename prompt to description, auto-describe schemas in prompt, add docs
- Rename `prompt` to `description` on DirectiveDefinition — a short
behavioral label rather than the full AI prompt blob
- Auto-generate directive schema signatures in the system prompt using
formatZodType, so the AI always sees every field, type, and optionality
- Add docs: guide page, API reference page, nav/title entries, docs-chat
* feat(directives): add standardDirectives export and composition hint
Export a pre-assembled standardDirectives array (all 7 non-factory
directives) for convenience. Add a composition hint to the generated
AI prompt so agents know directives can nest inside each other.
* docs: add directives skill, README entry, and docs-chat listing
- Add skills/directives/SKILL.md with full directive API reference
- Add @json-render/directives row to root README packages table
- Add "directives" to the Available skills list in docs-chat prompt
* perf(core): skip Zod parse in directive hot path
Resolvers are already defensive (coercion, fallbacks, switch defaults),
so runtime validation on every render adds overhead without safety.
The schema remains used for prompt generation and TypeScript inference.
* feat: add @json-render/gsplat package
Standalone Gaussian Splatting renderer using Hugging Face's gsplat.js.
Provides GaussianSplat and GaussianSplatViewer components with progress
indicator, orbit controls, and Zod-based catalog definitions — no
Three.js dependency required.

* feat: add GaussianSplat component to react-three-fiber
Adds GaussianSplat to the R3F renderer using drei's Splat loader,
bringing the component count to 20. Splats are composable with all
existing R3F components (lights, controls, post-processing, etc.).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add standalone gsplat example
Demo app showcasing @json-render/gsplat with 5 scenes (bonsai, garden,
bicycle, kitchen, stump) loaded from Hugging Face datasets. Includes
scene selector, live JSON spec viewer, and progress indicator.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add react-three-fiber gsplat example
Demo app showcasing GaussianSplat in R3F with 5 scenes: splat showroom,
splat with primitives, multi-splat, post-processing effects (bloom +
vignette), and animated floating splat with sparkles.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: add gsplat API reference and update navigation
Adds API documentation for @json-render/gsplat, updates the R3F docs
to reflect 20 components, and registers both example apps in the
docs navigation, examples list, and page titles.

* chore: add changeset and update lockfile for gsplat
Adds @json-render/gsplat to the fixed version group and creates a
changeset for the minor release of gsplat and react-three-fiber.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: wire up GaussianSplatViewer props to gsplat.js API
The catalog declared controls, autoRotate, autoRotateSpeed,
cameraPosition, cameraTarget, and fov props but the component
silently ignored them. Now:
- cameraPosition sets camera.position via SPLAT.Vector3
- cameraTarget calls controls.setCameraTarget()
- fov converts to focal length via camera.data.fx/fy
- controls=false skips OrbitControls creation
- autoRotate rotates the camera around Y in the render loop
- Updated gsplat.d.ts with full Camera/OrbitControls type surface
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(gsplat): address review issues — transforms, progress bar, themeable colors
- Apply per-splat position/rotation/scale after LoadAsync (splats were
rendering at origin regardless of config)
- Add eulerToQuaternion helper to convert Vec3 degrees to Quaternion
- Expose Splat class and correct LoadAsync return type (Promise<Splat>)
in gsplat.d.ts so transforms can be applied imperatively
- Forward visible prop through GaussianSplatHandle and SplatEntry
- Fix progress bar regression: use Math.max so bar never jumps backwards
- Make ProgressIndicator colors themeable via progressBarColor,
progressTrackColor, progressTextColor, progressBackgroundColor props
on GaussianSplatViewer
- Remove quality/alphaHash/toneMapped from standalone gsplat catalog —
these gsplat.js renderer has no equivalent API for them (they remain
in @json-render/react-three-fiber where drei's Splat supports them)
- Fix pre-existing TS2769/TS2322 Vec3 type errors in GaussianSplat.tsx
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(gsplat): pass required progress color props in example
The new themeable progress indicator props are nullable (required keys
that accept null) in the catalog schema. The example was missing them,
causing TS2739 in CI.

* refactor(gsplat): drop standalone @json-render/gsplat package
Per discussion in #259, the standalone gsplat viewer is better positioned
as an experimental example than as a published package — there's no real
spec tree to compose, and the R3F GaussianSplat component already covers
the productized use case.
- Remove packages/gsplat (was @json-render/gsplat)
- Inline the viewer component into examples/gsplat as an experimental demo
- Drop @json-render/{core,react,gsplat} deps from the example
- Remove gsplat from changeset config and feat-gsplat.md
- Remove docs/api/gsplat page and its navigation entries
- Update README to drop the standalone install/snippet
* fix(gsplat): address review issues, add ExtrudedText component, improve a11y
- Fix GridHelper prop names (color1/color2 → color/secondaryColor) in all R3F scene files
- Fix Text3D prop mismatch in splat-with-primitives (size → fontSize, remove unsupported bevel/font props)
- Fix autoRotate to orbit around camera target instead of world origin
- Add ExtrudedText component to @json-render/react-three-fiber (geometry-based 3D text with depth, bevel, and custom font support)
- Add multi-offset scene to gsplat example to demonstrate off-center orbit
- Redesign splat-with-primitives scene (triangle logo + extruded label, remove floor plane)
- Improve gsplat example accessibility (ARIA labels, keyboard nav, semantic HTML, focus management)
- Debounce resize handler and use consistent 100dvh in gsplat viewer

* feat: add @json-render/ink terminal renderer and ink-chat example
Adds a new `@json-render/ink` package that brings json-render specs to
terminal UIs via Ink (React for CLIs). Includes 24 standard components
(layout, text, inputs, markdown, etc.), context providers for state,
validation, visibility, actions, focus, and repeat scopes, plus a
streaming JSONL hook for progressive spec rendering.
Also adds an `ink-chat` example app demonstrating an AI chat interface
in the terminal with streaming responses, tool calls, and interactive
wizard flows.
Includes 76 tests (24 unit + 52 e2e), docs page, and web app integration.
* feat: show live spec preview during streaming
Render the spec progressively as JSONL patches arrive instead of only
showing a spinner. The preview disappears when streaming completes and
the finalized message replaces it in history.
* feat: clip streaming preview to 6 lines
* refactor: move spinner into input box, show full streaming preview
* fix: skip spacer during streaming to prevent clipping tall previews
* fix: strip invisible colors on dark terminal backgrounds
Drop foreground colors like "black" and "#000000" from AI-generated
specs so text remains readable on dark terminals. Removed hardcoded
color="black" from Badge and added safeColor() guard to all components
that accept user-specified color props.
* fix: always show spacer to keep input pinned to bottom
* fix: show dash placeholder for empty values in Table and KeyValue
Empty or null values in Table cells and KeyValue now render as "—"
instead of blank space. Also removed dimColor from ListItem subtitle
and trailing for better readability on dark terminals.
* fix: division by zero in Sparkline sampling when maxWidth is 1

- `@json-render/react` barrel-imports React contexts that call `createContext`, which crashes in Next.js App Router API routes (RSC runtime strips `createContext`)
- Updated all docs, READMEs, examples, and skills to import `schema` from `@json-render/react/schema` instead of `@json-render/react`
- For combined imports, split into separate `schema` (subpath) and client API (main entry) lines
Fixes#123
* external store adapter for state management
Introduces a `StateStore` interface that lets users plug in their own state management (Redux, Zustand, XState, etc.) instead of being locked into the internal `useState`-based store.
- Added `StateStore` interface and `createStateStore()` factory to `@json-render/core`
- `StateProvider`, `JSONUIProvider`, and `createRenderer` now accept an optional `store` prop for controlled mode
- When `store` is provided, it becomes the single source of truth (`initialState`/`onStateChange` are ignored)
- When `store` is omitted, everything works exactly as before (fully backward compatible)
- Applied across all platform packages: react, react-native, react-pdf

* generated prompt
* Add tests for catalog validation and prompt generation
- Test generateSystemPrompt with components, actions, custom rules
- Test new defineCatalog API from schema system
- Test catalog.prompt() method with custom rules
- Test catalog.validate() for valid and invalid specs
- Test catalog.zodSchema() for custom validation
- Test catalog.jsonSchema() for structured outputs
- Add tests for nested specs with children
- Add tests for rejecting invalid component types
* Fix lint: pass children as nested elements in renderer
Change from children={...} prop to nested children pattern
to satisfy react/no-children-prop rule.
* Fix lint errors in dashboard and web apps
- Disable react/prop-types in both eslint configs (TypeScript handles this)
- Allow styled-jsx 'jsx' property in dashboard
- Add DATABASE_URL to turbo env allowlist
- Remove unused drizzle-orm imports (and, sql)
- Suppress unused variable warnings where intentional
* Add server entry point for @json-render/remotion
The main package entry includes React components that require
client-side context (React.createContext). This causes build
failures when importing in server-side API routes.
Added `@json-render/remotion/server` entry point that exports
only schema and catalog definitions without React dependencies:
- schema, RemotionSchema, RemotionSpec
- standardComponentDefinitions, standardTransitionDefinitions
- standardEffectDefinitions
- Type exports for catalogs
Updated remotion example to import from /server in catalog.ts
* Make dashboard database connection lazy-initialized
The database connection threw an error at module load time if
DATABASE_URL was not set, causing builds to fail in CI where
the database is not available.
Changed to lazy initialization using a Proxy so the error only
occurs when the database is actually used at runtime, not at
build time.
* Fix previousSpec property name and lazy rate limiting
- Fix property name mismatch: playground now passes previousSpec
instead of previousTree to match what useUIStream hook expects
- Make rate limiting lazy-initialized to avoid runtime errors when
Redis env vars (KV_REST_API_URL, KV_REST_API_TOKEN) are not set
- Rate limiting gracefully becomes a no-op when Redis is unavailable
