Sharing & Presenting

Sharing Options

DexCode provides multiple ways to share your slides with others.

Cloudflare Tunnel

The fastest way to share a live deck. DexCode includes cloudflared as a dependency and has built-in tunnel management. Ask your AI agent:

> Expose this deck via Cloudflare Tunnel and share the URL

Or start a tunnel manually:

npx cloudflared tunnel --url http://localhost:3000

This generates a public URL (e.g., https://abc123.trycloudflare.com) that anyone can access. The viewer sees your slides in real time — any updates you make are reflected immediately.

PDF Export

Export your deck to a high-quality PDF via Playwright. Each slide is rendered at full resolution and combined into a single PDF file for sharing or printing.

PPTX Export

Export to PowerPoint format. Each slide is rendered as a high-resolution image and inserted into a PPTX file using pptxgenjs.

Presenter Mode

Use the presenter mode button in the toolbar to open a two-window presentation setup:

• Presenter window: Shows current slide, next slide preview, speaker notes, and timer
• Audience window: Shows the current slide fullscreen (ideal for projector output)

Both windows stay synchronized via BroadcastChannel API — no server needed.

Keyboard Shortcuts

Embedding

Since DexCode decks are standard web pages, you can embed them in other sites using an iframe:

<iframe
  src="https://your-tunnel-url.trycloudflare.com"
  width="100%"
  height="600"
  style="border: none; border-radius: 8px;"
></iframe>
