Key Patterns

Vietnamese Font Registration

import { Font } from '@react-pdf/renderer'

Font.register({
  family: 'BeVietnamPro',
  fonts: [
    { src: 'https://fonts.gstatic.com/s/bevietnampro/v12/...400.ttf' },
    { src: 'https://fonts.gstatic.com/s/bevietnampro/v12/...700.ttf', fontWeight: 700 },
  ]
})

Font.registerHyphenationCallback((word) => [word])  // Prevent Vietnamese splitting

Export API Route

// app/api/export/[id]/route.ts
import { renderToBuffer } from '@react-pdf/renderer'

export async function GET(req, { params }) {
  const { id } = await params
  const buffer = await renderToBuffer(<CVTemplate data={cvData} /> as any)
  return new Response(new Uint8Array(buffer), {
    headers: { 'Content-Type': 'application/pdf' }
  })
}

Client Preview (Dynamic Import)

const PDFViewer = dynamic(
  () => import("@react-pdf/renderer").then((mod) => mod.PDFViewer),
  { ssr: false }
)
