pigeon-client 2.0.1

A STOMP client with message definitions via Pydantic

Pigeon

Pigeon is a combination of a STOMP client, and a message definition system using Pydantic models.

Message Definitions

Messages are defined by writing a Pydantic model for each topic. These messages can be registered at runtime, or placed in a Python package and automatically loaded when Pigeon is imported using an entrypoint.

Logging

When a Pigeon client is instantiated, a logger is created. If desired, logs can also be sent to Grafana Loki by setting environment variables.
