description: Pre-built shadcn-svelte components for json-render Svelte apps. Use when working with @json-render/shadcn-svelte, adding standard UI components to a Svelte catalog, or building Svelte web UIs with shadcn-svelte + Tailwind CSS components.

@json-render/shadcn-svelte

Pre-built shadcn-svelte component definitions and implementations for json-render. Provides 36 components built on Svelte 5 + Tailwind CSS.

Two Entry Points

| Entry Point | Exports | Use For | |-------------|---------|---------| | `@json-render/shadcn-svelte/catalog` | `shadcnComponentDefinitions` | Catalog schemas (no Svelte dependency, safe for server) | | `@json-render/shadcn-svelte` | `shadcnComponents`, `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 `validateOn` for timing
• Events: inputs emit `change`/`submit`/`focus`/`blur`; buttons emit `press`; selects emit `change`/`select`
