STOMP

STOMP, which stands for Simple Text Oriented Messaging Protocol, is a simple, text-based protocol designed for working with message-oriented middleware. It provides an interoperable wire format that allows clients to communicate with almost any message broker if it supports STOMP. This simplicity and versatility make STOMP popular for building messaging applications across various languages and platforms.

Unlike other messaging protocols that use a binary format, STOMP uses a text-based protocol. This makes it easy to implement and debug. STOMP's design is aimed at providing an easy-to-implement messaging protocol that can be used to interact with a wide range of message brokers, ensuring broad interoperability.

The protocol defines a handful of commands (like CONNECT, SEND, SUBSCRIBE, UNSUBSCRIBE, BEGIN, COMMIT, ACK, NACK, and DISCONNECT), making it straightforward to use. Messages in STOMP are organized in frames, which are similar to HTTP messages. Each frame consists of a command, optional headers, and an optional body.

Due to its simplicity, there are STOMP clients available in many programming languages, making it a good choice for cross-language messaging. STOMP is suitable for scenarios where you need to connect different systems with a message broker but don't require the advanced features of more complex protocols like AMQP or MQTT.

Routing in STOMP is usually done using message headers, which makes it flexible to route messages based on various criteria. Many popular message brokers like Apache ActiveMQ, RabbitMQ, and others support STOMP, making it a versatile choice for different environments.

STOMP supports transactions, allowing a series of SEND, ACK, and NACK commands to be treated as a single atomic operation. STOMP can be used over WebSockets, which makes it an excellent choice for web applications requiring real-time messaging.
