Puppeteer can automate that!
summary
Puppeteer pairs with the Chrome DevTools Protocol and serverless functions to automate real tasks: over a dozen live demos show screenshots/PDF generation, device emulation, WhatsApp morning scheduler running in Google Cloud using a stored user data dir (family doesn’t notice), accessibility checks via injected axe script, code coverage reported with puppeteer-to-istanbul, TensorFlow object detection in-browser, FPS and heap monitoring, and a CLI PWA image generator that actually produces all Apple splash screens. Options include puppeteer-core + chrome-launcher to avoid bundling Chromium, and remote websocket control via performance.getMetrics.
