Family Chat

A private real-time chat for the whole family

What it is

Family Chat is our own private messaging app — real-time text plus voice — so the family has a space we control rather than a third-party service.

How it’s built

A Node.js / Express server pairs with a React (Vite) client. Socket.io carries real-time messages over WebSockets, message history lives in MySQL, and Twilio powers voice calling.

Design decisions

  • Socket.io abstracts away reconnection and transport fallback so messages feel instant and survive flaky connections.
  • MySQL-backed history means conversations persist and sync across devices.
  • Twilio voice adds calling without standing up our own telephony stack.

What I learned

Real-time state is deceptively hard — getting presence, ordering, and reconnection right took more care than the initial chat happy-path.
