Hey React devs,

I've been working on an open-source web chat app called Pulse Chat. My goal was to make a React web app feel indistinguishable from a premium native iOS app.

The hardest frontend challenge I faced was building the custom TransferManager. When users send media (images/videos), I couldn't just block the UI waiting for the server. I had to build a custom transfer state machine that handles pending, uploading, downloading, and paused states completely asynchronously.

It hooks directly into the browser's Service Worker (vite-plugin-pwa) to dynamically cache media blobs. If the user drops their connection, the PWA handles the offline state gracefully, and my custom WebSocket client immediately re-syncs the missing history chunks the moment they reconnect.

I also completely bypassed React's useState rendering cycle for the Lightbox pinch-to-zoom. I bound the gesture data directly to a ref to update the DOM imperatively, which easily hits a buttery smooth 60FPS on old mobile devices.

Would absolutely love feedback on my React component architecture and how I'm handling the media caching under the hood!

Hi everyone,

My sister is planning to join the Next IAS 1-year GS Pre-cum-Mains foundation offline in Delhi. She has already covered her basic NCERTs from 6th to 12th on her own and is ready to start full-time.

I was told that outgoing students get a student discount coupon that helps bring down the admission fee (usually by 10k to 20k). If any senior here has recently finished their batch and has a spare coupon they aren't planning to use, could you please DM me?

It would be a massive help in bringing the total fee down for her.

Thanks in advance, and all the best with your prep!
