markdown-to-pdf-kit

Nx + Next.js + TypeScript starter for exporting Markdown content to PDF without writing custom Markdown parsing logic.

Stack

• Nx workspace
• Next.js (App Router)
• TypeScript
• md-to-pdf for Markdown → PDF rendering

How it works

• UI page: apps/web/src/app/page.tsx
  • Paste Markdown
  • Click Export PDF
• API route: apps/web/src/app/api/export-pdf/route.ts
  • Accepts { markdown: string }
  • Generates PDF using md-to-pdf
  • Returns downloadable PDF bytes

Run locally

npm install
npx nx serve web

Open: http://localhost:4200

Export API

POST /api/export-pdf

Request body:

{
  "markdown": "# Hello\n\nThis will become a PDF."
}

Response:

• 200 application/pdf on success
• JSON error on failure

Notes

• The API route runs with runtime = 'nodejs'.
• Puppeteer launch flags include --no-sandbox for server compatibility.
• If deployment platform blocks Chromium, use a platform-supported browser runtime.
