Implementing OIDC with Sveltekit never has been easier:

In your hooks.server.ts

import { sequence } from '@sveltejs/kit/hooks';

export const OIDC = await makeOIDC({
    oidcAuthority: PUBLIC_OIDC_AUTHORITY,
    oidcClientId: PUBLIC_OIDC_CLIENT_ID,
    secret: OIDC_CLIENT_SECRET,
    authenticatedRoutes: ['/app'],
    async userLoggedInSuccessfully(user) {
        upsertUserAtDatabase();
    }
});

export const handle: Handle = sequence(OIDC.handle, otherHandler);

Now the user is available via the locals on your server.
