STOMP – Simple/Streaming Text Oriented Messaging Protocol

What is Stomp?

STOMP provides an interoperable wire format so that STOMP clients can communicate with any supported message broker to provide easy and widespread messaging interoperability among many languages, platforms and brokers.

It is the only one of these three protocols to be text-based, making it more analogous to HTTP in terms of how it looks under the covers. Like AMQP, STOMP provides a message (or frame) header with properties, and a frame body. The design principles here were to create something simple, and widely-interoperable. For example, it’s possible to connect to a STOMP broker using something as simple as a telnet client.

It does not, however, deal in queues and topics—it uses a SEND semantic with a “destination” string. The broker must map onto something that it understands internally such as a topic, queue, or exchange. Consumers then SUBSCRIBE to those destinations. Since those destinations are not mandated in the specification, different brokers may support different flavours of destination. So, it’s not always straightforward to port code between brokers.

However, It is simple and lightweight (although somewhat verbose on the wire), with a wide range of language bindings. It also provides some transactional semantics. One of the most interesting examples is with RabbitMQ Web Stomp which allows you to expose messaging in a browser through websockets. This opens up some interesting possibilities—like updating a browser, mobile app, or machine in real-time with all types of information.

Simple Design

It is a very simple and easy to implement protocol, coming from the HTTP school of design; the server side may be hard to implement well, but it is very easy to write a client to get yourself connected. For example you can use Telnet to login to any STOMP broker and interact with it!

Many developers have told us that they have managed to write a STOMPclient in a couple of hours to in their particular language, runtime or platform into the STOMPnetwork. So if your favored language/runtime of choice does not offer a good enough Simple/Streaming Text Oriented Messaging Protocol client don’t be afraid to write one.

The protocol is broadly similar to HTTP, and works over TCP using the following commands:

  • SEND
  • ACK
  • NACK

Communication between client and server is through a “frame” consisting of a number of lines. The first line contains the command, followed by headers in the form <key>: <value> (one per line), followed by a blank line and then the body content, ending in a null character. Communication between server and client is through a MESSAGE, RECEIPT or ERROR frame with a similar format of headers and body content.
