Building Reality with Next.js

The Matrix isn't just a movie—it's a blueprint. And with modern web technologies, we can construct our own simulated realities, immersive experiences that blur the line between user and participant.

The Foundation: Next.js 15

Next.js provides the infrastructure for our digital reality. Its features align perfectly with building complex, performant web experiences:

App Router Architecture

typescript
// app/layout.tsx - The root of reality
export default function RootLayout({
  children,
}: {
  children: React.ReactNode;
}) {
  return (
    <html lang="en" className="dark">
      <body className="bg-void-black text-matrix-green font-mono">
        <MatrixRainBackground />
        <Navigation />
        {children}
        <Footer />
      </body>
    </html>
  );
}

Server Components by Default

Server Components allow us to:

  • Fetch data at the speed of light (on the server)
  • Reduce client-side JavaScript
  • Improve initial page load
  • Stream content as it becomes available
tsx
// app/posts/[slug]/page.tsx
async function BlogPost({ params }: { params: { slug: string } }) {
  const post = await getPostBySlug(params.slug);

  if (!post) {
    notFound();
  }

  return (
    <article className="prose prose-invert max-w-4xl mx-auto">
      <h1>{post.frontmatter.title}</h1>
      <MDXContent source={post.content} />
    </article>
  );
}

The Canvas: MDX for Content

MDX bridges the gap between content and code. It's not just markdown—it's programmable content:

mdx
---
title: "Interactive Demo"
---

import { InteractiveCodeBlock } from '@/components/InteractiveCodeBlock';

# Try It Yourself

<InteractiveCodeBlock
  initialCode="console.log('Hello Matrix');"
  language="javascript"
/>

This isn't just reading about code—it's *experiencing* it.

MDX Configuration

The key is in the plugins:

javascript
// next.config.js
const withMDX = createMDX({
  options: {
    remarkPlugins: [
      remarkGfm,           // GitHub Flavored Markdown
      remarkMath,          // Mathematical expressions
    ],
    rehypePlugins: [
      rehypeSlug,          // Auto-generate heading IDs
      rehypeAutolinkHeadings,  // Add anchor links
      rehypePrettyCode,    // Syntax highlighting
    ],
  },
});

The Effects: Animation & Interaction

Cyberpunk aesthetics demand motion. Here's how to implement the digital rain:

typescript
// components/MatrixRain.tsx
'use client';

import { useEffect, useRef } from 'react';

export function MatrixRain() {
  const canvasRef = useRef<HTMLCanvasElement>(null);

  useEffect(() => {
    const canvas = canvasRef.current;
    if (!canvas) return;

    const ctx = canvas.getContext('2d');
    if (!ctx) return;

    // Set canvas size
    canvas.width = window.innerWidth;
    canvas.height = window.innerHeight;

    // Matrix characters
    const chars = 'ハミヒーウシナモニサワツオリアホテマケメエカキムユラセネスタヌヘ01234567890';
    const fontSize = 16;
    const columns = canvas.width / fontSize;

    // Array to track drop position for each column
    const drops: number[] = Array(Math.floor(columns)).fill(1);

    function draw() {
      if (!ctx || !canvas) return;

      // Fade effect
      ctx.fillStyle = 'rgba(10, 14, 39, 0.05)';
      ctx.fillRect(0, 0, canvas.width, canvas.height);

      ctx.fillStyle = '#00ff41';
      ctx.font = `${fontSize}px monospace`;

      for (let i = 0; i < drops.length; i++) {
        const char = chars[Math.floor(Math.random() * chars.length)];
        const x = i * fontSize;
        const y = drops[i] * fontSize;

        ctx.fillText(char, x, y);

        // Reset drop randomly
        if (y > canvas.height && Math.random() > 0.975) {
          drops[i] = 0;
        }

        drops[i]++;
      }
    }

    const interval = setInterval(draw, 33);

    return () => clearInterval(interval);
  }, []);

  return (
    <canvas
      ref={canvasRef}
      className="fixed inset-0 -z-10 opacity-20"
    />
  );
}

The Data Layer: Content Management

Organizing and querying blog content efficiently:

typescript
// lib/mdx.ts
import fs from 'fs';
import path from 'path';
import matter from 'gray-matter';
import { cache } from 'react';

// Use React's cache to deduplicate requests
export const getAllPosts = cache(() => {
  const postsDirectory = path.join(process.cwd(), 'content/posts');
  const filenames = fs.readdirSync(postsDirectory);

  return filenames
    .filter(filename => filename.endsWith('.mdx'))
    .map(filename => {
      const slug = filename.replace(/\.mdx$/, '');
      return getPostBySlug(slug);
    })
    .filter(Boolean)
    .sort((a, b) => {
      return new Date(b.date).getTime() - new Date(a.date).getTime();
    });
});

Performance Optimization

In the Matrix, every millisecond counts:

Image Optimization

tsx
import Image from 'next/image';

<Image
  src="/images/neon-city.jpg"
  alt="Neon cityscape"
  width={1200}
  height={630}
  priority={featured}
  placeholder="blur"
  blurDataURL="data:image/jpeg;base64,..."
/>

Code Splitting

tsx
// Lazy load heavy components
const CodeEditor = dynamic(() => import('@/components/CodeEditor'), {
  loading: () => <div>Loading editor...</div>,
  ssr: false,
});

Font Optimization

tsx
// app/layout.tsx
import { JetBrains_Mono } from 'next/font/google';

const jetbrainsMono = JetBrains_Mono({
  subsets: ['latin'],
  display: 'swap',
  variable: '--font-mono',
});

The User Experience

Great cyberpunk interfaces feel responsive and alive:

tsx
// components/GlitchText.tsx
'use client';

export function GlitchText({ children }: { children: string }) {
  const [glitched, setGlitched] = useState(children);

  useEffect(() => {
    const interval = setInterval(() => {
      if (Math.random() > 0.95) {
        // Temporarily scramble text
        const scrambled = children
          .split('')
          .map(char => Math.random() > 0.5 ? char : '█')
          .join('');
        setGlitched(scrambled);

        // Restore after 50ms
        setTimeout(() => setGlitched(children), 50);
      }
    }, 100);

    return () => clearInterval(interval);
  }, [children]);

  return <span className="glitch-text">{glitched}</span>;
}

Conclusion

Building immersive web experiences with Next.js is about more than just code—it's about crafting realities. Every component, every animation, every interaction contributes to the illusion.

The tools are here. The knowledge is available. The only question is: what reality will you build?

Free your mind.
