* fix: subdirectory redirects
* fix: use path-segment boundary check when stripping BASE_URL prefix
A bare `startsWith(BASE_URL)` matches on character prefix, not path
segments. With BASE_URL="/chat", a path like "/chatroom/c/abc" would
incorrectly strip to "room/c/abc" (no leading slash). Guard with an
exact-match-or-slash check: `p === BASE_URL || p.startsWith(BASE_URL + '/')`.
Also removes the dead `BASE_URL !== '/'` guard — module init already
converts '/' to ''.
* test: add path-segment boundary tests and clarify subdirectory coverage
- Add /chatroom, /chatbot, /app/chatroom regression tests to verify
BASE_URL stripping only matches on segment boundaries
- Clarify useAuthRedirect subdirectory test documents React Router
basename behavior (BASE_URL stripping tested in api-endpoints-subdir)
- Use `delete proc.browser` instead of undefined assignment for cleanup
- Add rationale to eslint-disable comment for isolateModules require
* fix: use relative path and correct instructions in subdirectory test script
- Replace hardcoded /home/danny/LibreChat/.env with repo-root-relative
path so the script works from any checkout location
- Update instructions to use production build (npm run build && npm run
backend) since nginx proxies to :3080 which only serves the SPA after
a full build, not during frontend:dev on :3090
* fix: skip pointless redirect_to=/ for root path and fix jsdom 26+ compat
buildLoginRedirectUrl now returns plain /login when the resolved path
is root — redirect_to=/ adds no value since / immediately redirects
to /c/new after login anyway.
Also rewrites api-endpoints.spec.ts to use window.history.replaceState
instead of Object.defineProperty(window, 'location', ...) which jsdom
26+ no longer allows.
* test: fix request-interceptor.spec.ts for jsdom 26+ compatibility
Switch from jsdom to happy-dom environment which allows
Object.defineProperty on window.location. jsdom 26+ made
location non-configurable, breaking all 8 tests in this file.
* chore: update browser property handling in api-endpoints-subdir test
Changed the handling of the `proc.browser` property from deletion to setting it to false, ensuring compatibility with the current testing environment.
* chore: update backend restart instructions in test subdirectory setup script
Changed the instruction for restarting the backend from "npm run backend:dev" to "npm run backend" to reflect the correct command for the current setup.
* refactor: ensure proper cleanup in loadModuleWithBase function
Wrapped the module loading logic in a try-finally block to guarantee that the `proc.browser` property is reset to false and the base element is removed, improving reliability in the testing environment.
* refactor: improve browser property handling in loadModuleWithBase function
Revised the management of the `proc.browser` property to store the original value before modification, ensuring it is restored correctly after module loading. This enhances the reliability of the testing environment.
