📝 WalkthroughWalkthroughThe documentation adds Node.js and Python session-middleware paths for login, callbacks, protected routes, refresh, and logout. It updates the Quickstart, session-management guide, OAuth journey pages, and planning records while retaining manual Go and Java flows. ChangesSaaSKit session middleware guidance
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR teaches session middleware through new first-run documentation, but the Python examples currently disable the Secure cookie flag, include a logout import that raises ImportError, and conflict with the shared redirect URI. The insecure cookie guidance creates a concrete security risk for copied production setups, so these examples should be corrected before merge.

✨ Finishing Touches
Warning Linked repositories: Your configuration references 5 linked repositories, but your current plan allows 1. Analyzed Comment |
Keep first-run steps self-contained. Node and Python tabs now show the callback, protect-route, and logout snippets on the page instead of sending the reader to another guide.
Keep first-run steps on the task. Method lists stay in the existing See also list, not between the prose and the snippet.

documentation so the session-middleware case appears before the general
statement that an endpoint is required. Remove the redundant “already” from the
middleware sentence while preserving the existing `/callback` registration
guidance.
In `@src/content/docs/authenticate/fsa/logout.mdx`:
- Around line 48-95: Standardize the TabItem.value identifiers across the FSA
documentation pages: add explicit values to the tab items in logout.mdx and use
the same Python value as quickstart.mdx instead of py in manage-session.mdx.
Keep the existing rendered labels and tab synchronization structure unchanged.
- Around line 194-206: Update the Flask example’s LogoutUrlOptions import to use
scalekit.common.scalekit instead of the top-level scalekit package, leaving the
logout flow unchanged.

- Around line 104-105: Align the redirect URI examples in the shared environment
block and the Go and Java quickstart tabs: make the callback paths consistent,

REDIRECT_URI example and the corresponding Go and Java callback references
without changing unrelated authentication configuration.

Put the condition before the general claim.
Line 34 tells every reader that the app still needs a callback endpoint. Line 36 then tells Node and Python readers that they do not write it. Order the two sentences so the middleware case comes first, and drop the duplicate "already".

Standardize TabItem.value across the FSA pages. The current mismatch does not affect synchronization because tabs match by rendered label, but logout.mdx omits values and manage-session.mdx uses py while quickstart.mdx uses python.

Fix the Flask LogoutUrlOptions import in both Python logout examples. Import it from scalekit.common.scalekit; the top-level scalekit package does not export it, so the examples currently fail with ImportError as written.

Align the callback path across tabs.
REDIRECT_URI is http://localhost:3000/callback, but the Go tab (Line 287) and the Java tab (Line 313) hard-code http://localhost:3000/auth/callback. A reader who follows the Go or Java tab registers a different redirect URI than the shared .env block declares. Use one path, or state that Go and Java use /auth/callback.

Open with what a session is and why you store tokens. Leave language split and Django out of the first screen.
Open each page with the original session and login story. Keep helper code in the tabs. Do not split languages in the opening.
