Bevy Replicon Matchbox

This crate integrates matchbox as a backend for bevy_replicon, enabling peer-to-peer networking via WebRTC, STUN, and ICE.

Matchbox provides convenient NAT traversal support out of the box — no need to manually manage signaling, host discovery, or ICE negotiation.

⚠️ Note: This is an early implementation and may still contain bugs or limitations.

Running an Example

To run one of the examples from the examples directory:

cargo run --example <example_name> server

in another terminal

cargo run --example <example_name> client

Each example starts a host peer that also acts as the listen server.

For production setups, it’s recommended to use a dedicated matchbox signaling server.

Known Limitations

• Empty message workaround
  WebRTC can silently drop empty messages. To prevent this, each message is currently prefixed with a single byte to ensure delivery.

• WASM support not verified (yet)
  This backend has not been tested in WebAssembly environments. Compatibility is currently unverified.
