Run bun install to apply patches.

next.config.mjs

Use the Pages Router with static export:

/** @type {import('next').NextConfig} */
const nextConfig = {
  reactStrictMode: true,
  reactCompiler: true,
  output: 'export',
}

export default nextConfig

Pages go in pages/ directory. Each file becomes a route. 'use client' directives should not be used since we are in the Pages router.

global.css

Tailwind 4 uses CSS-based configuration with @import. No tailwind.config.js needed.

@import 'tailwindcss';

body {
  background-color: #111;
  color: #eee;
}

html,
body,
#__next,
canvas {
  height: 100%;
  width: 100%;
}

.oxfmtrc.json

{
  "$schema": "./node_modules/oxfmt/configuration_schema.json",
  "printWidth": 120,
  "tabWidth": 2,
  "useTabs": false,
  "semi": false,

  "arrowParens": "avoid",
  "bracketSpacing": true,
  "sortTailwindcss": true,
  "ignorePatterns": ["node_modules", "dist", "out", ".next"]
}

tsconfig.json

No src/ folder - files live at the root. Use @/ for absolute imports.

No need to create tsconfig.json manually. Run bun run build and Next.js will create it. Add the @/ paths to the generated file:

{
  "compilerOptions": {
    "target": "ES2017",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,

    "paths": { "@/*": ["./*"] }
  },
  "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx"],
  "exclude": ["node_modules"]

Folder Structure

Create these folders and files:

  entities.tsx (empty)
models/
systems/
stores/
  core-store.ts
  ui-store.ts
  local-store.ts
lib/
  ecs.ts
  hooks.ts
  math.ts
components/
  ModelContainer.tsx

Boilerplate: r3f.d.ts
