User request: $ARGUMENTS
Custom objective: If the user's instruction is something other than a full migration plan (e.g. "which primitive should I use for this filter?", "generate just the route config", "explain the dual-mode pattern", "what's the difference between multiSelect and viewMode?", "how do I feed data bounds?"), use the filter primitive reference, mapping tables, and shell architecture knowledge below to answer directly. You are not bound to the 6-phase migration workflow.
Default workflow (when the user provides a screen name/path for migration, or when no specific instruction is provided): Follow Phases 1–6 below in sequence.
Read the migration guide first:
features/shell/new-ui-migration/FEATURE.md -- full architecture, filter reference, data-feeding lifecycle, design tokensThen read the shell implementation files for current filter types:
klair-client/src/shells/DesktopShell/FiltersContext.tsx -- all filter types, interfaces, settersklair-client/src/shells/DesktopShell/ConfigSidebar.tsx -- desktop filter renderingklair-client/src/shells/MobileShell/FilterSheet.tsx -- mobile filter renderingThe renewals screen is the gold standard. If you need to understand how a shell-integrated screen works end-to-end, read:
klair-client/src/shells/DesktopShell/routes.tsx (search for renewals)klair-client/src/screens/RenewalsShell/RenewalsShell.tsxScreens must work at both routes simultaneously. After migration:
/new-ui/...) and the legacy route (/...)useFiltersOptional() to detect which mode:
/new-ui/...)null when at the legacy route (no FiltersProvider wrapping it)useFiltersOptional() returns context): hide the inline filter component, read all filter values from appliedValues.* via the shell sidebaruseFiltersOptional() returns null): show the inline filter component as-is, read filter values from URL params / local state as beforeFilterBar.tsx) — it still renders on legacy routesApp.tsx — do NOT delete ituseMemo that normalizes from either sourceThe key pattern:
const shellFilters = useFiltersOptional();
const isShellMode = !!shellFilters;
Then conditionally render the inline FilterBar only when !isShellMode.
Read the target screen component thoroughly. For each piece of filter UI found:
| Filter | Current UI | Data Source | Behaviour |
|---|---|---|---|
| (name) | (dropdown / toggle / etc.) | (static / API / derived from data) | (multi-select / single / range / etc.) |
For each catalogued filter, map to the closest shell primitive:
Four generic primitives (prefer these):
| Shell Type | Use For |
|---|---|
dateRange | Any date range picker, time period selector, predefined period chips |
range | Any numeric min/max slider or range input |
viewMode | Any tab/toggle that changes the data perspective or display mode (2+ states) |
multiSelect | Any dropdown, checkbox group, or list selection -- configure N instances by key |
Legacy types have generic equivalents (don't use legacy for new screens):
| Legacy Type | Replace With |
|---|---|
period | multiSelect with singleSelect: true for year + quarter |
periodMonth | multiSelect with singleSelect: true for year + month |
timeRange | dateRange with dateRangeShowQuickPresets: true |
entityType | multiSelect |
businessUnit | multiSelect with { key: 'businessUnits' } |
classes | multiSelect with { key: 'classes' } |
businessUnitSingle | multiSelect with singleSelect: true |
classSingle | multiSelect with singleSelect: true |
multiSelect configuration properties:
| Property | Type | Description |
|---|---|---|
key | string | Unique ID, used in multiSelectValues[key] |
label | string | Sidebar display label |
singleSelect | boolean | Radio behavior (one value only) |
hideSearch | boolean | Hide search for short option lists |
hideAllToggle | boolean | Hide "All" checkbox |
showForViewMode | string or string[] | Conditional visibility based on viewMode |
tooltip | string | Help text on hover |
singleSelect guidance:
multiSelect (multi-select). Users benefit from filtering by multiple values (e.g., "High + Medium" impact, "Triage + Assigned" status).singleSelect: true when explicitly instructed, or when selecting multiple values is genuinely nonsensical (e.g., a time period like "Q1 2025", a view mode toggle, or a mutually exclusive grouping dimension).Produce a mapping table:
| Legacy Filter | Shell Primitive | Config Key | Notes |
|---|---|---|---|
| (name) | (dateRange / range / viewMode / multiSelect) | (config detail) | (any nuance) |
For each filter that does NOT cleanly map to an existing primitive:
Conservative enhancement principle:
maxOptions prop to multiSelect), suggest it as a targeted enhancementCustomFilterComponent as a fallback insteadOutput either:
CustomFilterComponent (genuinely complex cases only)Write the complete route config entry for routes.tsx:
const MyScreen = lazy(() => import('@/features/my-feature-v2/screens/MyScreen'));
// In newUIRoutes array:
{
path: 'my-screen',
title: 'My Screen',
element: <LazyScreen component={MyScreen} />,
filters: ['dateRange', 'viewMode', 'multiSelect'], // only types actually needed
filterDefaults: {
// dateRange config...
// viewMode config...
// multiSelect instances...
},
permissionPath: 'legacy-route-path', // maps to existing permission
}
Describe the changes needed to the screen component:
useFiltersOptional() import and const isShellMode = !!shellFilters at the top of the component<FilterBar>) in {!isShellMode && <FilterBar ... />}. Do NOT delete FilterBar.tsx — it still serves the legacy route.useMemo that normalizes filters from either source into a single object:
shellFilters.appliedValues.multiSelectValues[key], shellFilters.appliedValues.search, etc.isShellMode, call setMultiSelectOptions(), setRangeDataBounds(), setDateRangeDataBounds() after data loads. Guard these calls behind if (shellFilters).boundsOnly=true to preserve user selectionsisShellMode:
h-full overflow-y-autovar(--klair-*) tokensappliedValues not values for API callsApp.tsx. Do NOT delete the inline filter component file.Verify both shells will work correctly:
