@json-render/shadcn

Pre-built shadcn/ui component definitions and implementations for json-render. Provides 36 components built on Radix UI + Tailwind CSS.

Two Entry Points

Entry Point Exports Use For @json-render/shadcn/catalog shadcnComponentDefinitions Catalog schemas (no React dependency, safe for server) @json-render/shadcn shadcnComponents React implementations

Extending with Custom Components

Add custom components alongside standard ones:

const catalog = defineCatalog(schema, {
 components: {
 // Standard
 Card: shadcnComponentDefinitions.Card,
 Stack: shadcnComponentDefinitions.Stack,

 // Custom
 Metric: {
 props: z.object({
 label: z.string(),
 value: z.string(),
 trend: z.enum(["up", "down", "neutral"]).nullable(),
 }),
 description: "KPI metric display",
 },
 },
 actions: {},
});

const { registry } = defineRegistry(catalog, {
 components: {
 Card: shadcnComponents.Card,
 Stack: shadcnComponents.Stack,
 Metric: ({ props }) => {props.label}: {props.value}
,
 },
});

Built-in Actions (from @json-render/react)

These are built into the React schema and handled by ActionProvider automatically. They appear in prompts without needing to be declared in the catalog.

• setState - Set a value at a state path ({ statePath, value })

• pushState - Push a value onto an array ({ statePath, value, clearStatePath? })

• removeState - Remove an array item by index ({ statePath, index })

• validateForm - Validate all fields, write { valid, errors } to state ({ statePath? })

Validation Timing (validateOn)

All form components support validateOn to control when validation runs:

• "change" — validate on every input change (default for Select, Checkbox, Radio, Switch)

• "blur" — validate when field loses focus (default for Input, Textarea)

• "submit" — validate only on form submission

Important Notes

• The /catalog entry point has no React dependency -- use it for server-side prompt generation

• Components use Tailwind CSS classes -- your app must have Tailwind configured

• Component implementations use bundled shadcn/ui primitives (not your app's components/ui/)

• All form inputs support checks for validation (type + message pairs) and validateOn for timing

• Events: inputs emit change/submit/focus/blur; buttons emit press; selects emit change/select
