Quick Start

Client & Server

See the web-transport repository for client and server examples.

For a real-world example of using web-transport with MoQ, see the rs/moq-native/examples/chat.rs example which demonstrates connection setup, publishing, and session management.

Features

• Streams - Bidirectional and unidirectional streams
• Datagrams - Unreliable, unordered data
• Session Management - Peer/local addresses, graceful close
• TLS - Self-signed certificates (dev), Let's Encrypt (production), certificate fingerprints
• WebSocket Polyfill - See web-transport-ws

Integration with MoQ

The moq-lite crate uses web-transport internally. See the moq-native examples for how connections are established.

Next Steps

• Check the GitHub repository
• Use moq-lite for MoQ protocol
• Deploy a relay server
