# Transports A transport is a message queue that's able to receive messages. By default **@node-ts/bus** runs with an in memory queue transport, which is only really useful for development environments. When running in production, choose from one of the following officially supported transports: * [Amazon Simple Queue Service (SQS)](/guide/transports/amazon-sqs.md) * [Particular RabbitMQ](/guide/transports/rabbitmq.md) * [Redis](/guide/transports/redis.md) These transports are interchangeable and you write your message and handler definitions agnostic of the underlying transport. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://bus.node-ts.com/guide/transports.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
