Frontend

Next.js 15 with App Router architecture
React Server Components for optimized data fetching
Dynamic Routes for wallpaper detail pages:
- /live/[slug] - Dynamic live wallpapers
- /static/[slug] - High-res static wallpapers
Next Image for optimized responsive images
Tailwind CSS with custom theming

Backend & Hosting

Vercel Edge Functions for dynamic routing
Incremental Static Regeneration (ISR) for wallpaper pages
Server-Side Generation (SSG) for core pages
Route Handlers for API endpoints

Media Handling


jsx
// Example video player component
"use client";
import React, { useState } from 'react';

export default function VideoPlayer({ src, poster }) {
  const [isPlaying, setIsPlaying] = useState(false);

  return (
    <div className="relative aspect-[9/16]">
      {!isPlaying ? (
        <div onClick={() => setIsPlaying(true)}>
          <Image src={poster} fill className="object-cover" />
        </div>
      ) : (
        <video autoPlay loop muted playsInline>
          <source src={src} type="video/mp4" />
        </video>
      )}
    </div>
  );
}
Data Management
JSON Data Files for wallpaper metadata
Dynamic Import for code-splitting
Cached Data Fetching with fetch() API
Performance Optimizations
Lazy Loading for below-the-fold content
Skeleton Loading states
Optimized CLS (Cumulative Layout Shift)
AVIF/WebP image formats support
Video Poster Previews for live wallpapers
SEO Implementation
Dynamic Sitemap Generation
jsx
// app/sitemap.js
export default async function sitemap() {
  const wallpapers = await getWallpaperSlugs();

  return [
    { url: 'https://sajaboys.live', lastModified: new Date() },
    ...wallpapers.map(wp => ({
      url: `https://sajaboys.live/${wp.type}/${wp.slug}`,
      lastModified: wp.updatedAt,
    }))
  ];
}
Structured Data for rich results
Dynamic OG Image Generation
Key Architectural Decisions

1. Hybrid Rendering Approach
Combined SSG for static content with ISR for frequently updated wallpaper listings

2. Smart Media Delivery
jsx
<Image
  src={wallpaper.image}
  alt={wallpaper.title}
  width={1080}
  height={1920}
  priority={isAboveFold}
  placeholder="blur"
  blurDataURL={base64Placeholder}
/>
3. Client-Side Interactivity
Download manager with native <a download> behavior
Smooth transitions between wallpaper types
4. Error Handling
jsx
export default function WallpaperPage({ params }) {
  const wallpaper = await getWallpaper(params.slug);

  if (!wallpaper) notFound();

  // Render component...
}
