@json-render/shadcn

Pre-built shadcn/ui component definitions and implementations for json-render. Provides 36 components built on Radix UI + Tailwind CSS.

shadcnComponents

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

• 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

• "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
