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

@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 |

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

// 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,
  },
});

> State actions (`setState`, `pushState`, `removeState`) are built into the React schema and handled by `ActionProvider` automatically. No need to declare them.

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 }) => <div>{props.label}: {props.value}</div>,
  },
});

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
