# Interface: RabbitMqTransportConfiguration

Defined in: [packages/bus-rabbitmq/src/rabbitmq-transport-configuration.ts:4](https://github.com/node-ts/bus/blob/2e6cf65c27833b707ae31ee623cfb6343770f434/packages/bus-rabbitmq/src/rabbitmq-transport-configuration.ts#L4)

A common set of transport configuration options. This should be extended
by a provider-specific configuration that augments it with further options.

## Extends

* [`TransportConfiguration`](../../bus-core/interfaces/TransportConfiguration.md)

## Properties

| Property | Type | Description | Inherited from | Defined in |
| ------ | ------ | ------ | ------ | ------ |
| <a id="property-connectionrecovery"></a> `connectionRecovery?` | [`RabbitMqConnectionRecoveryConfiguration`](RabbitMqConnectionRecoveryConfiguration.md) | How to reconnect when the connection or channel to RabbitMQ is lost. After reconnecting, the transport re-declares its exchanges, queues and bindings and resumes consuming. The initial connection in `connect()` isn't retried and fails straight away if the broker can't be reached. **Default** `{ enabled: true, initialDelay: 100, maxDelay: 30000, factor: 2, jitter: 0.2, maxRetries: Infinity }` | - | [packages/bus-rabbitmq/src/rabbitmq-transport-configuration.ts:29](https://github.com/node-ts/bus/blob/2e6cf65c27833b707ae31ee623cfb6343770f434/packages/bus-rabbitmq/src/rabbitmq-transport-configuration.ts#L29) |
| <a id="property-connectionstring"></a> `connectionString` | `string` | The amqp connection string to use to connect to the rabbit mq instance **Example** `amqp://guest:guest@localhost` | - | [packages/bus-rabbitmq/src/rabbitmq-transport-configuration.ts:9](https://github.com/node-ts/bus/blob/2e6cf65c27833b707ae31ee623cfb6343770f434/packages/bus-rabbitmq/src/rabbitmq-transport-configuration.ts#L9) |
| <a id="property-deadletterqueuename"></a> `deadLetterQueueName?` | `string` | An optional name of the dead letter queue to fail messages to **Default** `dead-letter` **Example** `order-booking-service-dlq` | [`TransportConfiguration`](../../bus-core/interfaces/TransportConfiguration.md).[`deadLetterQueueName`](../../bus-core/interfaces/TransportConfiguration.md#property-deadletterqueuename) | packages/bus-core/dist/transport/transport-configuration.d.ts:16 |
| <a id="property-maxretries"></a> `maxRetries?` | `number` | The maximum number of attempts to retry a failed message before routing it to the dead letter queue. The delay between attempts comes from the bus's retry strategy (`withRetryStrategy`). **Default** `10` | - | [packages/bus-rabbitmq/src/rabbitmq-transport-configuration.ts:16](https://github.com/node-ts/bus/blob/2e6cf65c27833b707ae31ee623cfb6343770f434/packages/bus-rabbitmq/src/rabbitmq-transport-configuration.ts#L16) |
| <a id="property-persistentmessages"></a> `persistentMessages?` | `boolean` | Whether the messages in RabbitMQ are persistent or not (survive a broker restart). By default, false. | - | [packages/bus-rabbitmq/src/rabbitmq-transport-configuration.ts:21](https://github.com/node-ts/bus/blob/2e6cf65c27833b707ae31ee623cfb6343770f434/packages/bus-rabbitmq/src/rabbitmq-transport-configuration.ts#L21) |
| <a id="property-queuename"></a> `queueName` | `string` | The name of the queue that receives incoming messages **Example** `order-booking-service` | [`TransportConfiguration`](../../bus-core/interfaces/TransportConfiguration.md).[`queueName`](../../bus-core/interfaces/TransportConfiguration.md#property-queuename) | packages/bus-core/dist/transport/transport-configuration.d.ts:10 |
