# @lynkedup/map-sdk

A small TypeScript wrapper around `react-native-maps` to provide a consistent API and typed components.

## Usage

Install peer deps in your app:

```
npm install react-native react-native-maps
# and add this package via workspace or npm/yarn
```

Basic usage:

```ts
import React from 'react';
import { MapView, Marker, useLocationTracking, Polyline } from '@lynkedup/map-sdk';

export default function App() {
  const { isTracking, path, startTracking, stopTracking, clear } = useLocationTracking(/* opts?: TrackingOptions, geolocation?: GeolocationAPI */);

  return (
    <MapView style={{ flex: 1 }} initialRegion={{ latitude: 37.78825, longitude: -122.4324, latitudeDelta: 0.0922, longitudeDelta: 0.0421 }}>
      <Marker coordinate={{ latitude: 37.78825, longitude: -122.4324 }} />
      {path.length > 1 && <Polyline coordinates={path} strokeWidth={4} strokeColor="#007AFF" />}
    </MapView>
  );
}

> Tip: `useLocationTracking()` accepts an optional `TrackingOptions` object and an optional `GeolocationAPI` (handy for testing with a mocked geolocation provider). Ensure you request platform location permissions before starting tracking.
```

Tracking notes:
- `useLocationTracking()` uses the platform geolocation API (`navigator.geolocation.watchPosition`). Request permissions on iOS/Android as usual before starting tracking.
- It returns `{ isTracking, path, current, startTracking, stopTracking, clear }` so you can display the polyline and follow the user.

## Camera Controls 🔧

This package exposes a small imperative `MapHandle` API via `ref` on `MapView`. Use it to animate the camera or fit bounds.

Example:

```ts
const mapRef = useRef<MapHandle | null>(null);
mapRef.current?.flyTo({ latitude: 37.78825, longitude: -122.4324 });
mapRef.current?.fitBounds({ latitude: 37.809, longitude: -122.410 }, { latitude: 37.779, longitude: -122.450 });
```

Available methods:

- `animateToRegion(region, duration?)` — animate to a region.
- `animateCamera(camera, options?)` — animate using camera properties.
- `flyTo(coordinate, duration?)` — quick helper that animates to a small region around `coordinate`.
- `fitBounds(northEast, southWest, options?)` — fit the two coordinates with optional `edgePadding`.

### Camera presets

For convenience, `CameraPresets` provides common camera configurations you can pass into `animateCamera`.

Example:

```ts
import { CameraPresets } from '@lynkedup/map-sdk';
mapRef.current?.animateCamera(CameraPresets.viewOverlook({ latitude: 37.78825, longitude: -122.4324 }), { duration: 1000 });
```

Provided presets:

- `viewOverlook(center)` — tilt and rotate to create an overview with pitch ~65° and heading ~45°.
- `streetLevel(center)` — street-level view (pitch 0, zoom high).
- `overview(center)` — wide overview of the area.

## PropertyMap (high-level SDK component) ✅

`PropertyMap` is a ready-made map screen for property searches — it includes a search bar, clustering support, polygon rendering and a bottom property card. It's ideal to embed in apps that want a turn-key property map.

Install the extra peer deps in your app:

```bash
npm install react-native-map-clustering @react-native-community/geolocation
# and make sure react-native-maps is installed and configured
```

Basic usage:

```tsx
import React from 'react';
import { PropertyMap } from '@lynkedup/map-sdk';

export default function PropertiesScreen() {
  return (
    <PropertyMap
      apiUrl="https://your-api/property-search"
      initialRegion={{ latitude: 25.48, longitude: 81.85, latitudeDelta: 0.02, longitudeDelta: 0.02 }}
      showSearch
      radius={500}
      onSelectProperty={(item) => console.log('selected', item)}
    />
  );
}
```

Props summary:

| Prop | Type | Default | Description |
| ---- | ---- | ------- | ----------- |
| `apiUrl` | `string` | demo host | POST endpoint used for property searches. Should accept `{ location, radius }` and return `{ success, properties, location }`.
| `initialRegion` | `Region` | `DEFAULT_REGION` | Starting region for the map.
| `radius` | `number` | `500` | Search radius in meters.
| `showSearch` | `boolean` | `true` | Show or hide the built-in search bar.
| `onSelectProperty` | `(item: PropertyItem) => void` | — | Callback invoked when a property is selected.
| `mapProps` | `Partial<RNMapViewProps>` | — | Props forwarded to the underlying `react-native-maps` view (e.g., `mapType`, `showsMyLocationButton`).

## Notes
- This package delegates to `react-native-maps` for platform implementations. Follow `react-native-maps` docs for iOS/Android setup (Google Maps API key, pods, manifest permissions).
