@json-render/shadcn-svelte

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

Installation

npm install @json-render/shadcn-svelte @json-render/core @json-render/svelte zod

Quick Start

1. Create a Catalog

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

const catalog = schema.createCatalog({
  components: {
    Card: shadcnComponentDefinitions.Card,
    Stack: shadcnComponentDefinitions.Stack,
    Heading: shadcnComponentDefinitions.Heading,
    Button: shadcnComponentDefinitions.Button,
    Input: shadcnComponentDefinitions.Input,
  },
  actions: {},
});

2. Create a Registry

import { defineRegistry } from "@json-render/svelte";
import { shadcnComponents } from "@json-render/shadcn-svelte";

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

3. Render

<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>

Exports

Entry Point	Exports
@json-render/shadcn-svelte	shadcnComponents, shadcnComponentDefinitions
@json-render/shadcn-svelte/catalog	shadcnComponentDefinitions

The /catalog entrypoint contains only Zod schemas (no renderer dependency), so it can be used in server-side code for prompt generation.
