Project Status: Marco

Last Updated: Sat Jan 24 2026

Project Context

We are building Marco, a decentralized maps application using Ember.js (Octane/Polaris edition with GJS/GLIMMER), Vite, and OpenLayers. The core feature is storing place bookmarks in RemoteStorage.js, using a custom module structure.

What We Have Done

1. Map Integration

  • Set up OpenLayers in app/components/map.gjs (class-based component).
  • Switched tiles to OpenFreeMap Liberty style (supports vector POIs).
  • Implemented a hybrid click handler:
    • Detects clicks on visual vector tiles.
    • Falls back to fetching authoritative data from an Overpass API service.
    • Uses a heuristic (distance + type matching) to link visual clicks to API results (handling data desynchronization).
    • Logic Upgrade: Map intelligently detects if any sidebar/pane is open and handles outside clicks to close them instead of initiating new searches.
  • Optimization: Added 10px hit tolerance for easier tapping on mobile devices.
  • Visuals: Increased bookmark marker size (Radius 9px) and added a subtle drop shadow.
  • Feedback: Implemented a "pulse" animation (via OpenLayers Overlay) at the click location to visualize the search radius (30m/50m).
  • Mobile UX:
    • Disabled browser tap highlights (-webkit-tap-highlight-color: transparent) to prevent blue flashing on Android.
    • Disabled "pull-to-refresh" (overscroll-behavior: none) on the body to prevent accidental reloads while keeping the sidebar scrollable (contain).
    • Auto-Pan: On mobile screens, if a selected pin is obscured by the bottom sheet, the map automatically pans to center the pin in the visible top half of the screen.
  • Geolocation ("Locate Me"):
    • Implemented a "Locate Me" button with robust tracking logic.
    • Dynamic Zoom: Automatically zooms to a level where the accuracy circle covers ~10% of the map (fallback logic handles missing accuracy data).
    • Smart Pulse: Displays a pulsing blue circle during the search phase.
    • Auto-Stop: Pulse and tracking automatically stop when high accuracy (≤20m) is achieved or after a 10s timeout.
  • Persistence: Saves and restores map center and zoom level using localStorage (key: marco:map-view).
  • Controls: Enabled standard OpenLayers Rotate control (re-north) and custom Locate control.
  • Pin Animation: Selected pins are highlighted with a custom Red Pin overlay that drops in with an animation. The center dot is styled as a solid dark red circle (#b31412).

2. RemoteStorage Module (@remotestorage/module-places)

  • Created a custom TypeScript module in vendor/remotestorage-module-places/.
  • Schema: place object containing id (ULID), title, lat, lon, geohash, osmId, url, etc.
  • Storage Path: Nested <2-char>/<2-char>/<id> (based on geohash) for scalability.
  • API:
    • getPlaces(prefixes?): efficient partial loading of specific sectors (or full recursive scan if no prefixes provided).
    • Uses getListing for directory traversal and getAll for object retrieval.
    • configured with maxAge: false to ensure data freshness.
  • Dependencies: Uses ulid and latlon-geohash internally.

3. App Infrastructure

  • Services:
    • storage.js: Initializes RemoteStorage, claims access, enables caching, and sets up the widget. Consumes the new getPlaces API.
      • Optimization: Implemented Debounced Reload (200ms) for bookmark updates to handle rapid change events efficiently.
      • Optimization: Correctly handles deletion/updates by clearing stale data for reloaded geohash sectors.
    • osm.js: Fetches nearby POIs from Overpass API.
      • Configurable: Now supports dynamic API endpoints via SettingsService.
      • Reliability: Implemented fetchWithRetry to handle HTTP 504/502/503 timeouts and 429 rate limits, in addition to network errors.
    • settings.js: Manages user preferences (currently Overpass API provider) persisted to localStorage.
  • UI Components:
    • places-sidebar.gjs: Displays a list of nearby POIs.
      • Layout: Responsive design that transforms into a Bottom Sheet (50% height) on mobile screens (<=768px) with rounded corners and upward shadow.
    • place-details.gjs: Dedicated component for displaying rich place information.
      • Features: Icons (via feather-icons), Address, Phone, Website, Opening Hours, Cuisine, Wikipedia.
      • Layout: Polished UI with distinct sections for Actions and Meta info.
    • app-header.gjs: Transparent header with "Menu" button (Settings) and User Avatar (Login).
    • settings-pane.gjs: Sidebar component for app info ("About" section) and settings.
      • Features: Dropdown to select Overpass API provider (bke.ro, overpass-api.de, private.coffee).
      • Mobile: Renders as a 2/3 height bottom sheet on mobile.
      • Z-Index: Configured to overlay the Places sidebar correctly (z-index: 3200).
  • Geo Utils:
    • app/utils/geo.js: Haversine distance calculations.
    • app/utils/geohash-coverage.js: Logic to calculate required 4-char geohash prefixes for a given bounding box.

4. Routing & Data Optimization

  • Explicit URLs: Implemented routing support for specific OSM entities via /place/osm:node:<id> and /place/osm:way:<id>, distinguishing them from local bookmarks (ULIDs).
  • Smart Linking: The showPlaces action intercepts search results and automatically resolves them to existing Bookmarks if a match is found (via storage.findPlaceById). This ensures the app navigates to the persistent Bookmark URL (ULID) and correctly reflects the "Saved" status in the UI instead of treating it as a new generic OSM place.
  • Data Normalization: Refactored OsmService to return normalized objects (osmTags, osmType) for all queries. This ensures consistent data structures between fresh Overpass results and saved bookmarks throughout the app.
  • Performance: Optimized navigation to prevent redundant network requests. Clicking a map pin passes the existing data object to the route, skipping the model hook (no re-fetch) while maintaining correct deep-linkable URLs via a custom serialize hook in PlaceRoute.

Current State

  • Repo: The app runs via pnpm start.
  • Workflow:
    1. User pans map -> moveend triggers storage.loadPlacesInBounds.
    2. User clicks map -> "Pulse" animation -> hybrid hit detection (Visual Tile vs Overpass).
    3. Navigation: Selected place is checked against bookmarks; if found, it uses the Bookmark object. Otherwise, it uses the OSM object.
    4. Sidebar displays details via <PlaceDetails> component (Bottom sheet on mobile).
    5. User clicks "Save Bookmark" -> Stores JSON in RemoteStorage.
    6. RemoteStorage change event -> Debounced reload updates the map reactive-ly.
    7. Editing: User can edit the Title and Description of saved bookmarks via an "Edit" button in the details view.
    8. Settings: User can change the Overpass API provider via the new Settings menu.

Files Currently in Focus

  • app/templates/application.gjs: Core layout and "Outside Click" logic.
  • app/components/settings-pane.gjs: Settings UI.
  • app/services/settings.js: Settings persistence.

Next Steps & Pending Tasks

  1. Collections/Lists: Implement ability to organize bookmarks into lists/collections.
  2. Linting & Code Quality: Fix remaining CSS errors, remove inline styles in map.gjs, and address unused variables/runloop usage.
  3. Performance: Monitor performance with large datasets (thousands of bookmarks).
  4. Testing: Add automated tests for the geohash coverage, retry logic, and new editing features.

Technical Constraints

  • Template Style: Strict Mode GJS (<template>).
  • Package Manager: pnpm for the main app, npm for the vendor module.
  • Visuals: No Tailwind/Bootstrap; using custom CSS in app/styles/app.css.
