react-here-map

React components for rendering and working with Here Maps.

It simplifies the use of the Here Map JavaScript API with the help React components.

The components can be imported and easily rendered. It also comes with seamless configuration and modifications.

Installation

Using NPM:

npm i --save react-here-map

Using Yarn:

yarn add react-here-map

General Usage

import React from "react";
import ReactDOM from "react-dom";
import HPlatform, { HMap, HMapPolyLine } from "react-here-map";

const points = [
  { lat: 52.5309825, lng: 13.3845921 },
  { lat: 52.5311923, lng: 13.3853495 },
  { lat: 52.5313532, lng: 13.3861756 },
  { lat: 52.5315142, lng: 13.3872163 },
  { lat: 52.5316215, lng: 13.3885574 },
  { lat: 52.5320399, lng: 13.3925807 },
  { lat: 52.5321472, lng: 13.3935785 },
];

ReactDOM.render(
  <HPlatform
    app_id="YOUR_APP_ID"
    app_code="YOUR_APP_CODE"
    apikey={"YOUR_API_KEY_FOR_V3.1"}
    useCIT
    useHTTPS
    includeUI
    includePlaces
  >
    <HMap
      style={{
        height: "400px",
        width: "800px",
      }}
      mapOptions={{ center: { lat: 52.5321472, lng: 13.3935785 }, zoom: 10 }}
    >
      <HMapPolyLine points={points} />
    </HMap>
  </HPlatform>,
  document.getElementById("app")
);

Docs

The default export from this library instantiates the Here Maps platform, which is required before initialization of other libraries of the Here Map Javascript SDK.

The platform is expected to be a direct parent of all other supported components.

Interesting components are also exported, they can be customized using supported props.

Components

HPlatform - Platform initializer. All major components should be its direct child.
HMap - Default export from this module, should be used as a parent for other components
HMapPolyLine - Draws a polyline on the map. A direct child of the map
HMapPolygon - Draws a polygon on the map. A direct child of the map
HMapMarker - Puts a marker on the map. A direct child of the map
HMapCircle - Draws a circle on the map. A direct child of the map
HMapRectangle - Draws a rectangle on the map. A direct child of the map
Event Handling - Handling of user evens with HMap and it objects child of the map
HMapGeoCode - Turns a physical address to a point on the map
HMapRoute - Defines a route to locate two points. A direct child of the map
HMapLayer - Adds additional informational layer on the map. A direct child of the map

Usage in details

HPlatform

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

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
  includeUI
  includePlaces
>
  {/*Children come in here*/}
</HPlatform>;

All direct children of HPlatform component receives:

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

props

Props were determined by the options required for initializing a platform.

version PropTypes.string - One of the supported version. Defaults to 'v3/3.0'
app_id PropTypes.string.isRequired - Application ID from account dashboard
app_code PropTypes.string.isRequired - Application Code from account dashboard
app_code PropTypes.string.isRequired - API KEY for usage with version 3.1Code from account dashboard
mapType PropTypes.string - One of the above types accessed as a dot prop. Default 'normal.map'
interactive PropTypes.bool - Makes the map react to events. Needed for event handling
includeUI PropTypes.bool - Add the UI controls
includePlaces PropTypes.bool - Add the module for working with places
useCIT PropTypes.boolean - Default to true
useHTTPS PropTypes.boolean - Load the library using HTTPS. Default to true

HMap

Displays a Map for the types passed as props or default normal.map

Map types

{
  normal: ["map", "traffic", "panorama", "transit", "base", "xbase", "labels"],
  satellite: ["xbase", "base", "map", "traffic", "panorama", "labels"],
  terrain: ["xbase", "base", "map", "traffic", "panorama", "labels"],
  incidents: true
}

All direct children of HMap component receives:

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 bootsrapping the map and its items

In any case you wish to render a supported component of this library outside the context of the map, make sure to render 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 same object's reference

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 };

const markerIcon =
  '<svg width="24" height="24" ' +
