# `Mojentic.Realtime.Transport`
[🔗](https://github.com/svetzal/mojentic-ex/blob/v1.5.0/lib/mojentic/realtime/transport.ex#L1)

Transport behaviour for the realtime subsystem.

The gateway owns I/O against this contract so unit tests can replace
the live WebSocket with a scripted, deterministic transport.
Production implementation: `Mojentic.Realtime.MintTransport`.
