Render’s build environment is temporary. Chrome installed by Puppeteer gets deleted after build unless manually packaged.

This script:

Installs Puppeteer.

Downloads Chromium via Puppeteer.

Copies the browser binary into your project folder (./puppeteer_chrome), ensuring it’s available at runtime.

Usage at Runtime:
When launching Puppeteer, point to your packaged Chrome:


const browser = await puppeteer.launch({
  executablePath: './puppeteer_chrome/chrome/linux-138.0.7204.94/chrome-linux64/chrome',
  headless: true,
  args: ['--no-sandbox', '--disable-setuid-sandbox'],
});
