Entry Points

Aspire uses Python’s entry point system to allow for extensibility and integration with external libraries. This mechanism enables users to register custom components that can be seamlessly integrated into the Aspire framework.

Custom Flows

Aspire supports custom flow implementations via the aspire.flows entry point group. To register a new flow backend, define an entry point in your pyproject.toml like so:

[project.entry-points."aspire.flows"]
myflow = "my_module:MyFlowClass"

The specified class must inherit from aspire.flows.base.Flow (or one of the existing flow wrappers), implement the required methods and define the xp attribute which specifies the array namespace. You can then select your custom flow by setting flow_backend="myflow" when initializing Aspire.

For an example see GWFlow in aspire-gw (mj-will/aspire-gw).
