WalkieTalkie is a real-time communication application built with MongoDB, Fastify and React with TypeScript. It provides instant voice communication similar to traditional walkie-talkies, delivered entirely over the browser.
What it does
- Push-to-talk voice channels over a persistent real-time connection
- Fastify backend, chosen for low per-request overhead on high-frequency traffic
- MongoDB for users, channels and session state
- TypeScript end to end
