@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

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

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
