NATS transport adapter using Gnat.

phoenix_micro lists no gnat dependency — add it to YOUR app's mix.exs:

{:gnat, "~> 1.7"}

Gnat is pure Elixir — no rebar3, no C compiler, works on all platforms.

Features

• Core NATS pub/sub with native wildcard support (*, >).
• Queue groups for load-balanced consumer groups.
• Request/reply for RPC patterns.
• Automatic reconnect with exponential backoff on connection loss.
• Task.Supervisor-based dispatch (crashes don't kill the transport).
• Full telemetry coverage.
