Express / Node.js

import express from 'express';
import { PdfEngine, Page, Text, h } from 'nebula-pdf-engine';
import fs from 'fs';

const app = express();
const engine = new PdfEngine({
  fonts: [{ name: 'Inter', data: fs.readFileSync('./fonts/Inter-Regular.ttf'), weight: 400 }],
});

app.get('/invoice.pdf', async (_req, res) => {
  const pdf = await engine.generate(
    h(Page, { size: 'A4', padding: 40 }, h(Text, { style: { fontSize: 20 } }, 'Invoice')),
  );

  res.setHeader('Content-Type', 'application/pdf');
  res.setHeader('Content-Disposition', 'attachment; filename="invoice.pdf"');
  res.send(pdf);
});

app.listen(3000);

generate() returns a Node Buffer. Use res.send(buffer) or res.end(buffer) — there is no streaming API yet.
