wtf is demo-push-to-talk?

Colyseus's Push To Talk Example is a small proof-of-concept that shows how to build a walkie-talkie-style voice chat in a web browser. You press a button to record audio, and other people connected to the same server can hear it. It is designed as a starting point for developers who want to add real-time voice features to a web app. The project has two parts: a client (what runs in your browser) and a server (what runs on a backend machine to relay the audio). When you hold down the push-to-talk button, the client uses built-in browser tools to capture sound from your microphone and record it in small chunks. Those chunks are sent to the server, which forwards them to everyone else connected. Their browsers then play the audio back automatically. The README does not go into detail on the networking protocol or any advanced audio processing, but the core idea is straightforward: capture, send, relay, and play. This would be useful for a developer or small team prototyping a multiplayer game, a collaborative workspace, or any web app where users need quick, short voice messages rather than a full calling experience. Instead of dialing someone or joining a room, you just press a button and talk, similar to how a Discord voice channel or a two-way radio works. One notable limitation is that the demo does not currently work on Safari, because Apple's browser blocks audio from playing automatically without user interaction. This is a common hurdle for web audio projects. The code is written in TypeScript and is fairly minimal, making it easy to read and modify if you want to experiment with your own push-to-talk setup. It is an MIT-licensed starting point rather than a polished product.
