Replace the ad-hoc "workspace" abstraction with a focused, URL-driven
"sidebar view" registry that implements the modern Vercel / Cloudflare
drill-in pattern: clicking a top-level entry (e.g. System Settings)
swaps the sidebar to a contextual workspace, with a `← Back to
Dashboard` affordance, instead of stacking sub-navigation in the root.
Architecture
------------
- types.ts
+ SidebarView — declarative nested view config
(id, pathPattern, parent, getNavGroups)
+ SidebarViewParent — back-navigation descriptor
+ ResolvedSidebarView — { key, view, navGroups } returned by hook
+ SidebarData — slimmed to { navGroups } only
- Workspace — removed (logo/plan never rendered)
- lib/sidebar-view-registry.ts (new, replaces workspace-registry.ts)
+ SIDEBAR_VIEWS array — single source of truth for nested views
+ resolveSidebarView(pathname)
+ getNavGroupsForPath(pathname, t) — back-compat helper for the
command palette
- config/system-settings.config.ts
Refactored to export a single SYSTEM_SETTINGS_VIEW (SidebarView)
with parent `/dashboard/overview` + label `Back to Dashboard`.
- components/sidebar-view-header.tsx (new)
Renders only the back affordance (chevron + label). Uses the
default SidebarMenuButton size so its typography matches the
nav items below; collapses gracefully into icon mode via the
existing tooltip behavior. The redundant "title + icon" row was
removed — workspace context is already carried by the nav groups.
- hooks/use-sidebar-view.ts (new)
Encapsulates view resolution and root-nav filtering:
· matched view → returns its nav groups verbatim (route-level
beforeLoad guards already enforce access);
· no match → returns root nav groups, narrowed by user
role (admin gate) and useSidebarConfig
(admin × user sidebar_modules overlay).
- components/app-sidebar.tsx
Now a thin presentation layer: reads { key, view, navGroups }
from useSidebarView() and orchestrates the view transition via
AnimatePresence + MOTION_VARIANTS.sidebarSlide (respects
prefers-reduced-motion). No logic, no role checks, no path
matching — those live in the hook.
- components/command-menu.tsx
Switched to the new getNavGroupsForPath() API; behavior preserved.
Cleanup
-------
- Deleted layout/context/workspace-context.tsx (zero consumers).
- Deleted layout/lib/workspace-registry.ts and its
workspace-registry.example.ts companion (over-abstracted: name/id
metadata, isInWorkspace / getAllWorkspaces / WORKSPACE_IDS were
registered but never read).
- Removed `workspaces` field from useSidebarData (never consumed
after the top-switcher was dropped).
- Dropped WorkspaceProvider from authenticated-layout.tsx.
- Trimmed dead `Manage and configure` translation key from all six
locale files and from static-keys.ts.
i18n
----
Added the `Back to Dashboard` key to en, zh, fr, ja, ru, vi, and
registered it in static-keys.ts under "Sidebar views".
Verification
------------
- bun run typecheck: passes
- Lint: no new warnings/errors on the touched files
- Adding a new drill-in workspace now only requires registering a
SidebarView in SIDEBAR_VIEWS — no changes to AppSidebar required.
