# `PhoenixMicro.Transport.RabbitMQ`
[🔗](https://github.com/iamkanishka/phoenix_micro/blob/v1.0.0/lib/phoenix_micro/transport/rabbitmq.ex#L1)

RabbitMQ transport adapter using the `amqp` Hex package.

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

    {:amqp, "~> 3.3"}

> #### rebar3 / Windows note {: .warning}
>
> The `amqp` package depends on `rabbit_common`, an Erlang library that builds
> with **rebar3**. On Windows this requires `escript.exe` (part of the Erlang/OTP
> installation) to be on your `PATH`. If you see a rebar3 compile error, either:
>
> - Ensure Erlang/OTP is installed and `escript.exe` is on PATH, or
> - Use **NATS** or **Redis Streams** instead — both are pure Elixir with no
>   rebar3 or native-code dependencies.

## Features

- Persistent channels with automatic reconnection (exponential backoff).
- Per-consumer `basic.qos` prefetch for backpressure control.
- Dead-letter exchange (DLX) routing on NACK.
- Topic exchange routing with `#` and `*` wildcards (AMQP convention).
- Publisher confirms for reliable publishing.

          prefetch_count: 10,
          reconnect_interval: 2_000
        ]
