Choosing a Backend for Signaling
Evaluate different backend technologies (e.g., Node.js with WebSockets, Python with FastAPI) suitable for building a signaling server.
Signaling Server Backends
Welcome! In WebRTC, a signaling server is crucial. It helps peers find each other and exchange vital connection information before a direct peer-to-peer link can form.
But what powers this server? We need a backend technology that can handle real-time communication efficiently.
Why a Dedicated Backend?
WebRTC itself doesn't provide a signaling mechanism. It's up to you to implement it. This is where a dedicated backend server comes in.
- Coordinate Peers: Helps peers discover each other.
- Exchange Metadata: Shares crucial data like SDP offers/answers and ICE candidates.
- Manage Sessions: Keeps track of active connections.
