react-three-fiber

@json-render/react-three-fiber

React Three Fiber renderer for json-render. 19 built-in 3D components.

Two Entry Points

Entry Point	Exports	Use For
@json-render/react-three-fiber/catalog	threeComponentDefinitions	Catalog schemas (no R3F dependency, safe for server)
@json-render/react-three-fiber	threeComponents, ThreeRenderer, ThreeCanvas, schemas	R3F implementations and renderer

Usage Pattern

Pick the 3D components you need from the standard definitions:

import { defineCatalog } from "@json-render/core";
import { schema } from "@json-render/react/schema";
import { threeComponentDefinitions } from "@json-render/react-three-fiber/catalog";
import { defineRegistry } from "@json-render/react";
import { threeComponents, ThreeCanvas } from "@json-render/react-three-fiber";

// Catalog: pick definitions
const catalog = defineCatalog(schema, {
  components: {
    Box: threeComponentDefinitions.Box,
    Sphere: threeComponentDefinitions.Sphere,
    AmbientLight: threeComponentDefinitions.AmbientLight,
    DirectionalLight: threeComponentDefinitions.DirectionalLight,
    OrbitControls: threeComponentDefinitions.OrbitControls,
  },
  actions: {},
});

// Registry: pick matching implementations
const { registry } = defineRegistry(catalog, {
  components: {
    Box: threeComponents.Box,
    Sphere: threeComponents.Sphere,
    AmbientLight: threeComponents.AmbientLight,
    DirectionalLight: threeComponents.DirectionalLight,
    OrbitControls: threeComponents.OrbitControls,
  },
});

Rendering

ThreeCanvas (convenience wrapper)

<ThreeCanvas
  spec={spec}
  registry={registry}
  shadows
  camera={{ position: [5, 5, 5], fov: 50 }}
  style={{ width: "100%", height: "100vh" }}
/>

Manual Canvas setup

import { Canvas } from "@react-three/fiber";
import { ThreeRenderer } from "@json-render/react-three-fiber";

<Canvas shadows>
  <ThreeRenderer spec={spec} registry={registry}>
    {/* Additional R3F elements */}
  </ThreeRenderer>
</Canvas>
