README

A basic wrapper for Map Integrations using DataMaps.

Background

Every now and then, we need to implement some sort of map functionality that cannot be achieved using Google maps. DataMaps provides a powerfull, highly customizable framework for any kind of map functionalities. The purpous of this module is to provide a basic wrapper to easily integrate DataMaps into web projects.

Usage

The modul provides a Drupal library containing all necessary assets:

iq_datamaps/datamaps_base

It can be attached like any other drupal library. Besided the DataMaps distribution it contains very basic map and tooltip styling and a JS class to interact with DataMaps JS: iqDataMapsWrapper.

The iqDataMapsWrapper Class

Create a new JS object from the iqDataMapsWrapper class:

let mapObject = new iqDataMapsWrapper(element);

element: DOM Container element that will hold the map.

The iqDataMapsWrapper provides a set of base settings for DataMaps to print a basic world map and the following methods:

clearSettings()

Removes all base settings. DataMap's defaults are now applied.

Kind: public function

clearSettings()

Kind: public function

setScope(scope)

Kind: public function

Kind: public function

initMap(scope) ⇒ DataMaps Object

Uses initMap() to print a responsive map with a given set of custom settings.

Kind: public function

Use-cases / examples

Print a (responsive) world map:

let element = document.getElementById('map-wrapper');
let dataMap = new  iqDataMapsWrapper(element);
dataMap.initResponsiveMap();

Highlight countries on world map:

let element = document.getElementById('map-wrapper');
let dataMap = new  iqDataMapsWrapper(element);
let highlights = {
  'CHE': {fillKey:  'active'},
}
dataMap.initResponsiveMap({data:  highlights});

Print a swiss map

let element = document.getElementById('map-wrapper');
let dataMap = new  iqDataMapsWrapper(element);
dataMap.setScope('che');
dataMap.initResponsiveMap({
  setProjection:  function (element) {
    let  scaleFactor = element.offsetWidth * 12.5;
    var  projection = d3.geo.mercator()
      .center([8.2, 46.8182])
      .scale(scaleFactor)
      .translate([element.offsetWidth / 2, element.offsetHeight / 2]);
    var  path = d3.geo.path().projection(projection);
    return { path:  path, projection:  projection };
  }
});

Print a swiss map with markers

let element = document.getElementById('map-wrapper');
let dataMap = new  iqDataMapsWrapper(element);
let mapMarkers = [
  {
    'radius': 5,
    'latitude': 46.9376,
    'longitude': 7.3950,
    'tooltip_content':  "<strong>Oh, hi Marc!</strong>",
    'fillKey': 'active'
  }
];
dataMap.setScope('che');
dataMap.initResponsiveMap({
  setProjection:  function (element) {
    let  scaleFactor = element.offsetWidth * 12.5;
    var  projection = d3.geo.mercator()
      .center([8.2, 46.8182])
      .scale(scaleFactor)
      .translate([element.offsetWidth / 2, element.offsetHeight / 2]);
    var  path = d3.geo.path().projection(projection);
    return { path:  path, projection:  projection };
  }
}).bubbles(mapMarkers, {
  popupTemplate:  function (geo, data) {
    return  '<div class="map-tooltip">' + data.tooltip_content + '</div>';
  },
  highlightFillColor:  'var(--map-color-active)',
  highlightBorderColor:  'var(--map-color-active)',
});
