Middleware

There are some useful middleware included that you can use as described below.

DatabaseMiddleware

Because we use sessions in starlette-core, by default Sessions are defined globally. This means when you do a Session.commit() or Session.rollback() this can bleed accross active requests.

This middleware provides a scopefunc to the Session that isolates the session to a single request. See docs.

Using the DatabaseMiddleware

If you are using the database functionality provided by this package it is important to use this middleware. See docs.

Enable the middleware:

from starlette_core.middleware import DatabaseMiddleware

app.add_middleware(DatabaseMiddleware)

CurrentRequestMiddleware

This middleware provides a useful function to get the current request object. This enables modules to access the things like the current logged in user outside of the view/endpoint.

Enable the middleware:

from starlette_core.middleware import CurrentRequestMiddleware

app.add_middleware(CurrentRequestMiddleware)

Access the request object:

from starlette_core.middleware import get_request

request = get_request()
if request:
    user = request.get("user")
