- Node.js: v18.x or v20.x+ recommended
- npm / yarn / pnpm / bun
- Word / PowerPoint / Excel / HTML to PDF need a conversion backend (planned: Gotenberg behind a Cloudflare Pages Function at
POST /api/convert). Until it is deployed, leaveNEXT_PUBLIC_CONVERT_ENABLEDunset and those tools show a "temporarily unavailable" state. See.env.exampleandsrc/lib/convertApi.ts.
