Summary

Fix custom map icon sizing and compatibility for previously cached map markers.

Changes

  • Updated getMapDataAndMarkers to always request fullSizeIcons=true, ensuring uploaded icons are returned at their full size.
  • Added the fullSizeIcons query parameter to the mapping endpoint definition and pending Swagger contract.
  • Scaled uploaded 128 px icons to the standard 32 px map pin size while keeping status and bundled icons at their existing scale.
  • Added per-pin icon scale metadata to MapLibre symbol features.
  • Versioned persisted map marker data to version 1.
  • Added migration handling for version 0 cached markers:
    • Removes previously persisted uploaded IconUrl values that referenced undersized 32 px renditions.
    • Preserves marker locations, map center, zoom, fetch timestamps, and status pin information.
    • Handles empty or partial legacy storage safely.
  • Added tests covering the API query, icon scaling behavior, persistence versioning, and legacy storage migration.

Walkthrough

The mapping endpoint now requests full-size icons. Pin features carry an icon scale, and MapPins applies that scale to the configured icon size.

Changes: Map pin icon sizing

Layer / File(s) Summary
Request full-size icons and define scale metadata
packages/api/src/endpoints/mapping/mapping.ts, packages/maps/src/lib/pin-features.ts
The endpoint sends fullSizeIcons: true. Uploaded icons use a scale of 32/128; styled remote and bundled icons use a scale of 1.
Propagate and apply pin icon scale
packages/maps/src/lib/pin-features.ts, packages/maps/src/components/map-pins.tsx
Pin feature properties carry the resolved icon scale, defaulting to 1 when no icon is available. MapPins multiplies the configured icon size by that scale.

Estimated code review effort: 2 (Simple) | ~10 minutes

Suggested reviewers: github-actions

Merge Risk: Low · up to 416bf

After upgrading, previously cached map markers may show tiny uploaded icons until the next successful data fetch. The impact is cosmetic and recovers on refresh, so the change is mergeable with a small follow-up to migrate the stored markers.

Explanation

The title "RO-T101 Custom Map Icon Fixes" names the work item and the area changed. The changeset adjusts custom (uploaded) map icon sizing: uploaded icons get a scale of 32/128, pin icons multiply iconScale by iconSize, and the mapping endpoint sends fullSizeIcons as true. The title is specific to the main change, though it does not say what was fixed (sizing).

Full details: Description check

Explanation

The description follows the template's Summary section with a clear, specific list of changes: the fullSizeIcons query parameter, icon scaling from 128 px to 32 px, per-pin iconScale metadata, persisted marker versioning, and the version 0 migration. It also states the tests added. However, the template's other sections are missing: 'Apps affected' is not ticked, 'Platforms affected' is not ticked, 'How it was tested' does not name the suites, devices, or what was not tested, and the Checklist is absent (lint, type-check, test, i18n, and other items are not confirmed). The linked issue is also not referenced, although the objectives mention RO-T101.

Resolution

Complete the remaining template sections: (1) tick the affected apps and platforms; (2) in 'How it was tested', list the Jest suites run (including the new API query, icon scaling, persistence versioning, and legacy migration tests), the devices or browsers used, and anything not tested; (3) add the checklist status, confirming pnpm lint, pnpm type-check, and pnpm test pass; state whether i18n text changed; and confirm that no app identity or persisted store name changed without a migration. Also reference the issue (for example RO-T101 or 'Fixes #123') in the Summary.

Minor · Functional Correctness · Quick win

Restored markers from earlier builds can render their uploaded icons at 8 px.

Markers persisted by earlier builds can hold 32 px IconUrl values, because those builds fetched without fullSizeIcons. The store persists markers with no version bump or migrate (map-markers-store.ts:70-73). After upgrade, rehydration restores these markers, and resolvePinIcon still applies the 0.25 upload scale. The pin then draws at about 8 px. This persists offline until a successful fetch replaces markers.

Bump the store version and drop IconUrl from markers saved before the change. Those markers then fall back to PinIconUrl at scale 1.

Suggested fix

     dataPersistOptions<MapMarkersState, Omit<MapMarkersData, 'loading' | 'errors'>>({
       name: 'omni-map-markers-storage',
       partialize: (state) => ({ markers: state.markers, centerLatitude: state.centerLatitude, centerLongitude: state.centerLongitude, zoomLevel: state.zoomLevel, fetchedAt: state.fetchedAt }),
+      version: 1,
+      migrate: (persisted, version) => {
+        // SAFETY: Version 0 data has the same shape as the partialized state; only the marker IconUrl values need changing.
+        const state = persisted as Omit<MapMarkersData, 'loading' | 'errors'>;
+        if (version >= 1) return state;
+        return { ...state, markers: state.markers.map((marker) => ({ ...marker, IconUrl: null })) };
+      },
