• 4. Encoding any given image into WebP using Web Assembly (implemented in C++)
• Real time bandwidth measurement for users
• Experimenting with experiences for users spread across different network throughput. Potentially based on Client Hints for measuring bandwidth on the server.

• 2. “Fire and forget” pipeline - Running in background on the Service Worker thread, heavily relying on “background sync” and upcoming “background fetch”. E.g. Web Chat, KYC upload flow
• 3. RUM tool for measuring various real time metrics like network, bundle size, UI interactions, UI Jank, Service Worker boot time (and navigation preload) etc.
• 4. Puppeteer - Automation of pre-production system code like bundle size, business metrics etc.
• Performance - UI performance, like load, scroll, UX and animations. Flipkart Lite implements Preloading (of critical resources) and runtime prefetching for resources based on user funnel.
