shadcnComponentDefinitions

Svelte implementations + catalog schemas

Usage Pattern

Pick the components you need from the standard definitions. Do not spread all definitions -- explicitly select what your app uses:

import { defineCatalog } from "@json-render/core";
import { schema } from "@json-render/svelte/schema";
import { shadcnComponentDefinitions } from "@json-render/shadcn-svelte/catalog";
import { defineRegistry } from "@json-render/svelte";
import { shadcnComponents } from "@json-render/shadcn-svelte";

// Catalog: pick definitions
const catalog = defineCatalog(schema, {
  components: {
    Card: shadcnComponentDefinitions.Card,
    Stack: shadcnComponentDefinitions.Stack,
    Heading: shadcnComponentDefinitions.Heading,
    Button: shadcnComponentDefinitions.Button,
    Input: shadcnComponentDefinitions.Input,
  },
  actions: {},
});

// Registry: pick matching implementations
const { registry } = defineRegistry(catalog, {
  components: {
    Card: shadcnComponents.Card,
    Stack: shadcnComponents.Stack,
    Heading: shadcnComponents.Heading,
    Button: shadcnComponents.Button,
    Input: shadcnComponents.Input,
  },
});

Then render in your Svelte component:

<script lang="ts">
  import { Renderer, JsonUIProvider } from "@json-render/svelte";

  export let spec;
  export let registry;
</script>

<JsonUIProvider initialState={spec?.state ?? {}}>
  <Renderer {spec} {registry} />
</JsonUIProvider>

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 Svelte dependency -- use it for server-side prompt generation
Components use Tailwind CSS classes -- your app must have Tailwind configured
Component implementations use bundled shadcn-svelte primitives (not your app's
```
$lib/components/ui/
```
)
All form inputs support
```
checks
```
for validation (type + message pairs) and
```

```
for timing
Events: inputs emit
