With pi-pilgrim

DrivineAssembly is a pi-pilgrim assembly holding the registry and the managers, for your own assembly to use. It needs pip install "drivine[pilgrim]":

from pipilgrim import AssemblyHolder, PilgrimAssembly
from drivine.drivine_assembly import DrivineAssembly      # drivine.sync.drivine_assembly for the sync API


class AppAssembly(PilgrimAssembly):
    def __init__(self):
        self.drivine = AssemblyHolder.shared(DrivineAssembly)
        super().__init__()

    def route_repository(self) -> RouteRepository:
        return self.shared(lambda: RouteRepository(self.drivine.persistence_manager()))

    def report_repository(self) -> ReportRepository:
        return self.shared(lambda: ReportRepository(self.drivine.persistence_manager("analytics")))

• It registers the database the environment describes. To register yours in code, subclass it and override register_databases(registry).
• Assembled injects a manager into a class something else makes: pm: PersistenceManager = Assembled(assembly=DrivineAssembly).
• Call await assembly.drivine.close() when the application stops, in FastAPI’s lifespan, say.

Nothing else needs pi-pilgrim: import drivine doesn’t load it, and the managers are plain classes.
