Documentation

Visit our reference document site to get an overview of what the MapsIndoors SDK offers.

Getting started

$ npm install @mapsindoors/react-native-maps-indoors-google-maps

iOS

The MapsIndoors SDK requires iOS 14, so make sure that your podfile is configured for iOS 14

platform :ios, '14.0

Providing API key

1. Navigate to iOS/MyApp/AppDelegate.m.
2. Import #import "GoogleMaps/GoogleMaps.h" on the class.
3. Add this code as the first line inside the application function: [GMSServices provideAPIKey:@"YOUR GOOGLE MAPS API KEY HERE"];

Adding MapsIndoors script specific to Google Maps, to Podfile

Note from version 2.1.1 this is no longer necessary, and should be removed from the podfile if upgrading to 2.1.1

After this you should navigate into the iOS folder of your react native project and add this script to the applications Podfile: MapsIndoors podfile Post install

Android

Android Gooogle Maps Setup

​ To get the underlying Google Map to function, you need to perform the following steps: ​

1. Navigate to android/app/src/main/res/value.
2. Create a file in this folder called google_maps_api_key.xml.
3. Copy and paste the below code snippet and replace YOUR_KEY_HERE with your Google Maps API key.
4. Add the key to your application metadata in the manifest, located at android/app/src/main/AndroidManifest.xml ​

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="google_maps_key">YOUR_KEY_HERE</string>
</resources>

<application>
    ...
    <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="@string/google_maps_key" />
    ...
</application>

MapsIndoors Gradle Setup

​ The plugin Gradle project has trouble resolving the MapsIndoors dependency, so to ensure that it is resolved correctly, do the following: ​

1. Navigate to the app's project level build.gradle.
2. add maven { url 'https://maven.mapsindoors.com/' } to allprojects/repositories after mavenCentral() ​

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://maven.mapsindoors.com/' }
    }
}

Expo

This library includes an expo plugin to support native integration. To enable it, you need to add the configuration in your expo configuration.

// app.json

{
  "expo": {
    // ... your configuration
    "plugins": [
      [
        "expo-build-properties",
        {
          "ios": {
            "deploymentTarget": "14.0"
          }
        }
      ],
      [
        "@mapsindoors/react-native-maps-indoors-google-maps/app.plugin.js",
        {
          "apiKeyAndroid": "GMAPS_ANDROID_API_KEY",
          "apiKeyIOS": "GMAPS_IOS_API_KEY"
        }
      ]
    ]
  }
}

Usage

Showing your map

This snippet shows you how to set up MapsIndoors in a React Native application.

import MapsIndoors, { MapControl, MapView } from 'react-native-maps-indoors';
...
//Function to initialize mapsindoors and mapcontrol. To load a solution and show data onto the map.
const loadMapsIndoors = () => {
    //Load solution data with your api key
    MapsIndoors.load('API_KEY').then(async () => {
        //Create the MapControl. Which will be using the MapView of the component.
        const mc = await MapControl.create(new MPMapConfig({useDefaultMapsIndoorsStyle: true}), NativeEventEmitter);
        //Get a venue and move the camera to it.
        let venue: MPVenue = (await MapsIndoors.getVenues()).getAll()[0];
        mapControl.goTo(venue);
    }
}

...
render() {
  return (
    <MapView
        style={{
            width: Dimensions.get('window').width,
            height: Dimensions.get('window').height,
        }}
    />
  );
}
...

Showing a route

  const showRoute = async () => {
    let point = new MPPoint(57.0580431, 9.9505475);
    let point2 = new MPPoint(57.0581638, 9.9507732, 10);
    var directionsService = await MPDirectionsService.create();

    //Optional query parameters for the route.
    directionsService.setIsDeparture(true);
    directionsService.setTime(Date.now());
    directionsService.setTravelMode('bicycling');

    var route = await directionsService.getRoute(point, point2);
    directionsRenderer = new MPDirectionsRenderer(NativeEventEmitter);
    directionsRenderer.setRoute(route);
  };

Searching locations

This code snippet shows a function called searchForParking that takes a single argument of type MPPoint. The function uses MapsIndoors to search for locations matching the query string "parking" near the point specified, and uses the filter to only get the first 10 matches. ​ It mathces in the locations' descriptions, names, and external IDs to the query string. Once the search is complete, it is possible to update/get information from the locations (not specified in the code snippet).

const searchForParking = async (point: MPPoint) => {
    let query = MPQuery.create({query: "parking",
                                near: point,
                                queryProperties: [MPLocationPropertyNames.description, MPLocationPropertyNames.name, MPLocationPropertyNames.externalId]});
    let filter = MPFilter.create({take: 10});
    let parkingLotsNearPoint = await MapsIndoors.getLocationsAsync(query, filter);
}

Changing the look with DisplayRules

​ This code snippet shows three ways to manipulate display rules in the MapsIndoors SDK. ​ The hideLocationsByDefault method hides all markers that are not explicitly visible by setting the main display rule to not visible. ​ The showLocationsByDefault method ensures all markers are shown by setting the main display rule to visible. ​ The changeTypePolygonColor(String type, String color) method changes the fill color for all polygons belonging to a specific type. It gets the display rule for the specified type using getDisplayRuleByName, and sets the fill color using setPolygonFillColor. ​ These methods can all be used to customize the display of markers and polygons on the map. ​

// This method changes the main display rule to hide all markers,
// This will cause all locations/types that are not explicitly visible to be hidden.
const hideLocationsByDefault = async () => {
    let mainDisplayRule = await MapsIndoors.getMainDisplayRule();
    mainDisplayRule?.setVisible(false);
}
​
// This method changes the main display rule to show all markers,
// This will cause all locations/types that are not explicitly visible to be shown.
const showLocationsByDefault = async () => {
    let mainDisplayRule = await MapsIndoors.getMainDisplayRule();
    mainDisplayRule?.setVisible(true);
}
​
// This method changes the fill color for all polygons belonging to a specific [type]
// the color MUST be a valid hex color string.
const changeTypePolygonColor = async (type: string, color: string) => {
    let typeDisplayRule = await MapsIndoors.getDisplayRuleByName(type);
    typeDisplayRule?.setPolygonFillColor(color);
}
