takp_puppeteer_express.js

const express   = require('express');
const puppeteer = require('puppeteer');

const app = express();

app.get('/:id', async (req, res) => {
  const itemId  = req.params.id;
  console.log('Request itemId: ' + itemId);

  const browser = await puppeteer.launch({args:['--no-sandbox']});
  const page    = await browser.newPage();

  await page.goto(
    'https://www.takproject.net/allaclone/item.php?id=' + itemId
  );

  const itemElement = await page.$('div.item-wrapper');

  if (!itemElement) {
    await browser.close();
    return res.send('error');
  }

  const bytes = await itemElement.screenshot();

  await browser.close();

  res.set('Content-Type', 'image/png');
  res.set('Content-Length', bytes.length);
  res.send(bytes);
});

app.get('/', (req, res) => { res.send('Hello') });

app.listen(3000, () => console.log('Listening on port 3000...'));
