Tech Stack

• React + TypeScript + Vite — Modern, fast frontend
• Tailwind CSS — Utility-first styling
• pdf-lib — Client-side PDF manipulation (merge, split, rotate, metadata, etc.)
• PDF.js — PDF page rendering for thumbnails
• nginx — Production serving (Docker)

Self-Hosting

LocalPDF is designed for self-hosting. The Docker image is a minimal nginx container serving static files.

docker build -t localpdf .
docker run -p 8080:80 localpdf

The nginx configuration includes:

• Security headers (CSP, X-Frame-Options, X-Content-Type-Options)
• Gzip compression
• Static asset caching
• SPA fallback routing

Development

npm install    # Install dependencies
npm run dev    # Start dev server (http://localhost:5173)
npm run build  # Production build
npm run lint   # Run ESLint
npx tsc -b     # Type check
