Slidev

Slidev - Presentation Slides for Developers

Web-based slides maker built on Vite, Vue, and Markdown.

When to Use

• Technical presentations or slidedecks with live code examples
• Syntax-highlighted code snippets with animations
• Interactive demos (Monaco editor, runnable code)
• Mathematical equations (LaTeX) or diagrams (Mermaid, PlantUML)
• Record presentations with presenter notes
• Export to PDF, PPTX, or host as SPA
• Code walkthroughs for developer talks or workshops

Quick Start

pnpm create slidev    # Create project
pnpm run dev          # Start dev server (opens http://localhost:3030)
pnpm run build        # Build static SPA
pnpm run export       # Export to PDF (requires playwright-chromium)

Verify: After pnpm run dev, confirm slides load at http://localhost:3030. After pnpm run export, check the output PDF exists in the project root.
