[CI-1] React+THREE.js Project Scaffold With TypeScript Configuration

Mar 12, 2025 by ADMIN 69 views

Technical Objective

Establish a minimal viable scaffold for THREE.js integration with React that validates our core rendering pipeline without unnecessary abstractions. Focus on precise TypeScript typings that enforce architectural boundaries while enabling rapid component iteration.

Implementation Requirements

Configure Vite Build Pipeline with Optimized THREE.js Tree-Shaking

To ensure efficient rendering, we need to configure the Vite build pipeline to optimize THREE.js tree-shaking. This involves targeting specific r165 imports only, which will significantly reduce the bundle size and improve performance.

// vite.config.js
import { defineConfig } from 'vite';
import { resolve } from 'path';

export default defineConfig({
  // ... other configurations ...
  build: {
    lib: {
      entry: resolve(__dirname, 'src/index.ts'),
      name: 'my-lib',
      fileName: 'my-lib',
      formats: ['es', 'umd'],
      // Target specific r165 imports only
      rollupOptions: {
        external: ['three@^0.165'],
      },
    },
  },
});

Implement Strict TypeScript Configuration

To ensure strict type checking and prevent implicit any types, we need to configure TypeScript with the following settings:

noImplicitAny: true
strictNullChecks: true
exactOptionalPropertyTypes: true
noUncheckedIndexedAccess: true

// tsconfig.json
{
  "compilerOptions": {
    // ... other configurations ...
    "noImplicitAny": true,
    "strictNullChecks": true,
    "exactOptionalPropertyTypes": true,
    "noUncheckedIndexedAccess": true,
  },
}

Establish Module Boundary Pattern with Proper Path Aliasing

To maintain a clean and organized codebase, we need to establish a module boundary pattern with proper path aliasing. This can be achieved by creating a tsconfig.paths.json file that defines the path aliases.

// tsconfig.paths.json
{
  "compilerOptions": {
    // ... other configurations ...
    "paths": {
      "@components/*": ["src/components/*"],
      "@utils/*": ["src/utils/*"],
    },
  },
}

Implement WebGL Context Initialization with Progressive Capability Detection

To ensure smooth rendering, we need to implement WebGL context initialization with progressive capability detection. This involves checking for WebGL 1.0 support and falling back to a different rendering path if necessary.

// src/webgl-context.ts
import { WebGLRenderer } from 'three';

const initWebGLContext = (canvas: HTMLCanvasElement): WebGLRenderer => {
  const renderer = new WebGLRenderer({
    canvas,
    antialias: true,
  });

  // Check for WebGL 1.0 support
  if (!renderer.capabilities.isWebGL2) {
    // Fall back to WebGL 1.0 rendering
    renderer.setPixelRatio(1);
  }

  return renderer;
};

Configure React-Three-Fiber with Explicit Typing of Extension Objects and Custom Fiber Elements

To ensure proper typing and avoid implicit any types, we need to configure React-Three-Fiber with explicit typing of extension objects and custom fiber elements.

// src/react-three-fiber.ts
import { Canvas } from 'react-three-fiber';

interface CustomFiberElement {
  // Define custom fiber element properties
}

const CustomFiberElement: React.FC<CustomFiberElement> = ({ children }) => {
  // Render custom fiber element
  return <canvas>{children}</canvas>;
};

const CanvasWithCustomFiberElement = () => {
  return (
    <Canvas>
      <CustomFiberElement />
    </Canvas>
  );
};

Implement Camera Control Hook with OrbitControls Integration and Proper Disposal Pattern

To ensure smooth camera control, we need to implement a camera control hook with OrbitControls integration and proper disposal pattern.

// src/use-camera-controls.ts
import { useEffect, useRef } from 'react';
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls';

const useCameraControls = (
  cameraRef: React.RefObject<THREE.PerspectiveCamera>,
  domElement: HTMLElement | null
): void => {
  useEffect(() => {
    if (!cameraRef.current || !domElement) return;

    const controls = new OrbitControls(cameraRef.current, domElement);
    controls.enableDamping = true;
    controls.dampingFactor = 0.25;
    controls.enableZoom = true;
    controls.minDistance = 20;
    controls.maxDistance = 500;

    return () => {
      controls.dispose();
    };
  }, [cameraRef, domElement]);
};

Validation Vectors

Build Process Completes with Zero TypeScript Errors

To ensure a successful build process, we need to verify that there are no TypeScript errors.

# Run TypeScript build command
tsc --noEmit

Initial Load Time < 2s on Reference Hardware

To ensure a smooth user experience, we need to verify that the initial load time is less than 2 seconds on reference hardware.

# Run performance benchmarking command
web-vitals --benchmark

WebGL Context Initialization < 100ms

To ensure smooth rendering, we need to verify that the WebGL context initialization time is less than 100 milliseconds.

# Run performance benchmarking command
web-vitals --benchmark

Memory Baseline < 50MB at Initialization

To ensure efficient memory usage, we need to verify that the memory baseline is less than 50 megabytes at initialization.

# Run memory profiling command
node --prof --heap-prof

Framerates > 90fps with Empty Scene (60fps Minimum)

To ensure smooth rendering, we need to verify that the framerates are greater than 90 frames per second with an empty scene (60 frames per second minimum).

# Run performance benchmarking command
web-vitals --benchmark

Camera Control Operates with Proper Event Disposal on Unmount

To ensure proper camera control, we need to verify that the camera control operates with proper event disposal on unmount.

// src/use-camera-controls.ts
import { useEffect, useRef } from 'react';
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls';

const useCameraControls = (
  cameraRef: React.RefObject<THREE.PerspectiveCamera>,
  domElement: HTMLElement | null
): void => {
  useEffect(() => {
    if (!cameraRef.current || !domElement) return;

    const controls = new OrbitControls(cameraRef.current, domElement);
    controls.enableDamping = true;
    controls.dampingFactor = 0.25;
    controls.enableZoom = true;
    controls.minDistance = 20;
    controls.maxDistance = 500;

    return () => {
      controls.dispose();
    };
  }, [cameraRef, domElement]);
};

Architectural Notes

Strict Separation between Rendering Layer, State Management Layer, and Procedural Generation Layer

To ensure a maintainable and scalable architecture, we need to enforce strict separation between the rendering layer, state management layer, and procedural generation layer.

// src/index.ts
import { Canvas } from 'react-three-fiber';
import { useCameraControls } from './use-camera-controls';
import { useStore } from './use-store';
import { useTerrainGenerator } from './use-terrain-generator';

const App = () => {
  const cameraRef = useRef<THREE.PerspectiveCamera>(null);
  const domElement = useRef<HTMLElement>(null);
  const store = useStore();
  const terrainGenerator = useTerrainGenerator();

  useCameraControls(cameraRef, domElement);

  return (
    <Canvas>
      <Camera ref={cameraRef} />
      <TerrainGenerator store={store} terrainGenerator={terrainGenerator} />
    </Canvas>
  );
};

Historical Context

Roman Urban Planning Principles within a THREE.js Context

To accurately represent Roman urban planning principles within a THREE.js context, we need to establish a robust architectural pattern that enforces strict separation between the rendering layer, state management layer, and procedural generation layer.

// src/terrain-generator.ts
import { TerrainGenerator } from 'three/examples/jsm/terrain/TerrainGenerator';

const terrainGenerator = new TerrainGenerator();

terrainGenerator.generateTerrain({
  width: 100,
  height: 100,
  depth: 100,
  resolution: 10,
  noiseScale: 0.1,
  noiseOctaves: 6,
