👀 / Overview

Since the creation of this library, many features have been added. At this point in time the following features are present and usable:

1. Display a (interactive) map in your webapp
2. Add (custom styled) markers, lines, circles, etc. to the map
3. Calculate and show routes between different coordinates
4. Calculate and show isochrone views by duration, distance or fuel consumption
5. Use GeoCoding to find locations or reverse search coordinates

📝 / Docs

Usage of the map requires atleast the HPlatform and HMap components. All other components are optional.

  • The HPlatform has to be the parent of the HMap.
  • The HMap has to be the parent of all other components.
  • All other components have to be a direct child of the HMap
// Simplified representation

import React from 'react';
import { HPlatform, HMap, ...} from 'react-here-map';

function Map() {
  return (
    <HPlatform>
      <HMap>

Usage in details

HPlatform

A container for all of the components in this library. Generates a platform that gets injected into all of its direct children.

// HPlatform with all possible props

import React from 'react';
import { HPlatform } from 'react-here-map';

function Map() {
  return (
    <HPlatform
      app_id='YOUR_APP_ID'

      mapType='normal.map'
      interactive
      includeUI
      useLocation
      includePlaces
      useHTTPS
    >
      // All children go in here 🧒
    </HPlatform>
  );
}

export default Map;
Prop name Description Type Default value
app_id HERE Application ID String Required
app_code HERE Application Code String Required
apikey HERE API key for usage with version 3.1 String -
version HERE map API version String 'v3/3.0'
language Language of the map and the UI (if included) - Options String 'EN' (English)

Language options

'EN' //English
'GER' //German
'SPA' //Spanish
'FIN' //Finish
'ITA' //Italian
'DUT' //Dutch
'POL' //Polish
'POR' //Portugese
'RUS' //Russian
'TUR' //Turkish
'CHI' //Chinese

Map types

// normal.traffic, normal.base, etc.
normal: ["map", "traffic", "base", "xbase", "panorama", "labels", "transit"],

// satellite.xbase, satellite.label, etc.
satellite: ["map", "traffic", "base", "xbase", "panorama", "labels"],

// terrain.map, terrain.panorama, etc.
terrain: ["map", "traffic", "base", "xbase", "panorama", "labels"],

All direct children of the HPlatform component receive:

  • platform A reference to H.service.platform Docs
  • options A reference to the options used to bootstrap the scripts: See here

HMap

Displays the HERE Map

import React from 'react';
import { HPlatform, HMap } from 'react-here-map';

function Map() {
  const style = { width: '800px', height: '500px' };
  const mapOptions = { center: { lat: 52.092876, lng: 5.10448 }, zoom: 7 };

  return (
    <HPlatform
      app_id='YOUR_APP_ID'
      app_code='YOUR_APP_CODE'
      apikey='YOUR_API_KEY'
      interactive
      includeUI
    >
      <HMap style={style} mapOptions={mapOptions}></HMap>
    </HPlatform>
  );
}

export default Map;
Prop name Description Type Default value
style Set style options for the map, like width and height object { width: '100%', height: '100%' }
mapEvents Options (Official Docs) object -
mapOptions Options (Official Docs) object { center: { lat: 0, lng: 0 }, zoom: 2 }

All direct children of the HMap component receive:

  • map A reference to the map object used to create the visual map. Docs
  • platform A reference to H.service.platform Docs
  • ui A reference to the ui object that does inclusion of ui elements. Docs
  • __options A reference to the options merged with writable defaults used in bootstrapping the map and its items

if you wish to render a supported component of this library outside the context of the map, make sure to render it in a place where the above props can be passed explicitly to avoid nasty, unfriendly errors.

In some cases, as we will soon see, there is an option for passing a custom component with more enhancements (defined by the programmer), these props are received as first class directly from the containing parent and not from HMap, but still holds the same object references

Event Handling

This section demonstrates how to use an event with either HMap component or a map object.

HMap Event Handling

No additional prop is required aside from those requiredby HMap. Below is a working code for a pointerup event:

To use an event, you have to pass interactive to the HPlatform and pass in useEvents and mapEvents props to the HMap like this:

import { HPlatform, HMap, HMapPolyline } from 'react-here-map';

<HPlatform
  app_id='YOUR_APP_ID'
  app_code='YOUR_APP_CODE'
  apikey={'YOUR_API_KEY_FOR_V3.1'}
  useCIT
  useHTTPS
  interactive // Required for events
  includeUI
  includePlaces
>
  <HMap
    style={{
      height: '400px',
      width: '800px'
    }}
    mapOptions={{ center: { lat: 52.5321472, lng: 13.3935785 } }}
    useEvents // Required for events
    mapEvents={{ pointerdown: (e) => console.log('Map Pointer Down', e) }} // event handlers
  />
</HPlatform>;

Map Object event handling

All map object handles events the same way. Since all map objects are direct children of HMap and receives HPlatform information, useEvents props in the HMap tells the map objects to initialize events. So, a single useEvents props is sufficient for all the children. In case that only a map object is expected to handle events, useEvents can be passed to the object which will initialize events defined for that object and not on the rest of the other sibling objects of the same HMap parent.

Usage
import HPlatform, {
  HMap,
  HMapCircle,
  HMapMarker,
  HMapPolygon,
  HMapPolyline,
  HMapRectangle
} from 'react-here-map';

const rectanglePoints = [51.5072, 0, 48.8567, 2.3508];
const rectangleOptions = {
  style: {
    fillColor: '#FFFFCC',
    strokeColor: '#E8FA75',
    lineWidth: 8
  }
};
const circleCoords = { lat: 52.3667, lng: 4.9 };
const circleOptions = {
  style: {
    strokeColor: 'rgba(55, 85, 170, 0.6)', // Color of the perimeter
    lineWidth: 2,
    fillColor: 'rgba(0, 128, 0, 0.7)' // Color of the circle
  }
};

const polyLinePoints = [
  { lat: 52.5167, lng: 13.3833 },
  { lat: 50.0833, lng: 14.4167 },
  { lat: 52.2333, lng: 21.0167 }

const polygonPoints = [45.4667, 9.1833, 0, 48.1333, 11.566, 0, 50.08, 8.24, 0];
const polygonOptions = {
  style: {
    fillColor: '#FFFFCC',
    strokeColor: '#829',
    lineWidth: 8
  }
};

const markerCoords = { lat: 48.2, lng: 16.3667 };

HMapRoute

This uses React Hooks. Ensure that your react installation supports Hooks API

Displaying route on the Map Using normal line

Shows path to between two points based on params

Props
  • routeParams: PropTypes.object - Officially documented route params
  • lineOptions: PropTypes.object - Officially supported poly line options
  • icon: PropTypes.any - Icon to be used for the marker
  • markerOptions: PropTypes.object - Officially supported marker Options
  • children: PropTypes.element - React element that receives map, platform, ui, route, key, routeShape as props
  • renderDefaultLine: PropTypes.bool - Should use default renderer instead of a custom renderer as children
  • isoLine: PropTypes.bool - Use IsoLine instead of a Polyline
Usages
Using the default renderer
import React from 'react';
