fastapi-healthcheck-sqlalchemy 0.1.0

A service to check the health of your applications SQLAlchemy connection.

fastapi-healthcheck-sqlalchemy

A module built on top of fastapi_healthcheck to check the status of your SQLAlchemy connection. This requires a Table given to the health check so it can run a count of rows against it. As long as it returns a value, the connection is alive.

from fastapi_sqlalchemy import DBSessionMiddleware
from fastapi_healthcheck import HealthCheckFactory, healthCheckRoute
from fastapi_healthcheck_sqlalchemy import HealthCheckSQLAlchemy


app = FastAPI()

# Bring SQLAlchemy online first.
app.add_middleware(DBSessionMiddleware, db_url=cs.value)

_healthChecks = HealthCheckFactory()
_healthChecks.add(
    HealthCheckSQLAlchemy(
        # The name of the object for your reference
        alias='postgres db',  

        # The Table that we will run a count method against.
        table=SmtpContactsSqlModel, 

        tags=('postgres', 'db', 'sql01')
    )
)

app.add_api_route('/health', endpoint=healthCheckRoute(factory=_healthChecks))
