    Getting Started

    This guide will walk you through setting up and using MapLayr in your React Native application.

    Install the MapLayr SDK using npm or yarn:

    npm install @maplayr/react-native
    # or
    yarn add @maplayr/react-native

    Create a file called attractions.io.config.json in the root directory of your React Native project:

    {
        "apiKey": "your_api_key",
        "mapLayr": {
            "maps": {
                "map_name_1": "map_id_1",
                "map_name_2": "map_id_2"
            },
            "android": {
                "github": {
                    "username": "github_username",
                    "personalAccessToken": "github_personal_access_token"
                }
            }
        }
    }

    Maps can be bundled into your app at build time so they are available immediately to users. These are specified in the mapLayr.maps block. Each key/value pair specifies a friendly map name against the map ID:

    "mapLayr": {
        "maps": {
            "attractionsIoResort": "df98bfa3-156c-49cb-9f94-1b9ec52a08c4"
        }
    }

    The friendly map name keys are currently not used in the React Native framework.

    GitHub package registry requires authentication credentials to fetch the native Android SDK. Create a personal access token by navigating to: https://github.com/settings/tokens/new

    Enable the following scope:

    • read:packages

    Update your Podfile (located at ios/Podfile) to include use_frameworks! and add the MapLayr dependency:

    target 'YourAppName' do
  use_frameworks!
  
  # MapLayr iOS SDK dependency (required)
  pod 'MapLayr', :git => 'https://github.com/attractions-io/maplayr-ios.git', :commit => 'c0af108cf44915e986cc9e775f6045952d79510a'
  
  # ... rest of your configuration
end

    Note: The MapLayr iOS SDK is not available on the CocoaPods public registry, so you must specify the git source directly in your Podfile.

    After making these changes, run:

    cd ios && pod install
    1. In Xcode, open your project and select your target
    2. Go to Build Phases
    3. Click the + button and select New Run Script Phase
    4. Drag the new phase to appear after Copy Bundle Resources
    5. Name it "MapLayr Configuration"
    6. Uncheck "Based on dependency analysis"
    7. Add the following script:
    xcrun --sdk macosx swift "${PODS_ROOT}/../../node_modules/@maplayr/react-native/scripts/maplayr_configuration.swift"
    1. In the Input Files section, add:
    ${BUILT_PRODUCTS_DIR}/${INFOPLIST_PATH}

    Here's a basic example of how to load and display a map:

    import React from 'react';
    import { ActivityIndicator, StyleSheet, View, Text } from 'react-native';
    import { MapView, useMap } from '@maplayr/react-native';

    export default function App() {
      const mapId = "your-map-id";
      const mapLoadResult = useMap(mapId);

      switch (mapLoadResult.status) {
        case "pending":
          return (
            <View style={styles.container}>
              <ActivityIndicator size="large" />
            </View>
          );
        
        case "success":
          return (
            <View style={styles.container}>
              <MapView style={styles.map} map={mapLoadResult.map} />
            </View>
          );
        
        case "error":
          return (
            <View style={styles.container}>
              <Text>Failed to load map: {mapLoadResult.error.message}</Text>
            </View>
          );
      }
    }

    const styles = StyleSheet.create({
      container: {
        flex: 1,
      },
      map: {
        flex: 1,
      },
    });

    The useMap hook loads the map and returns a result object with three possible states:

    • pending: The map is still loading
    • success: The map loaded successfully and is available via mapLoadResult.map
    • error: The map failed to load, with error details in mapLoadResult.error

    Now that you have a basic map displayed, you can explore additional features:
