# Configuration

The extension is configured in the JMap Admin project configuration page: 

1. Open the NG Configuration tab. 
2. Drop the javascript code that will be executed when opening, then save.<br>

3. Once the javascript code is saved, activate the extension in the **Extensions** section of a project configuration page. Make sure the code is functional before activating the extension, otherwise errors may occur when opening JMap NG for current users of the project.<br>

The following code adds an Atari logo and a base map from Geogratis. It also zooms to coordinates 45.630701447925134, -73.54322795543986 :

```
JMap.Map.Attribution.addMultiple([{
    id: "custom-attribution-0",
    text: "? K2Geospatial",
    imageUrl: "https://upload.wikimedia.org/wikipedia/commons/thumb/3/3b/Atari_logo.svg/640px-Atari_logo.svg.png",
    href: "https://k2geospatial.com/jmap-en/"
}, {
    id: "custom-attribution-1",
    text: "? StackOverflow",
    href: "https://stackoverflow.com/"
}]);
JMap.Map.Basemap.removeById("canvec");
JMap.Map.Basemap.add({
    id: "canvec",
    label: "Geogratis-test",
    tileUrls: [
        "https://maps.geogratis.gc.ca/wms/canvec_en?&amp;version=1.3.0&amp;REQUEST=GetMap&amp;format=image/png&amp;transparent=true&amp;width=512&amp;height=512&amp;crs=EPSG:3857&amp;bbox={bbox-epsg-3857}&amp;layers=land,hydro,man_made,residentialarea_50k,transport,administrative"
    ]
}, true);
JMap.Map.panAndZoomTo({
    "x": -73.54322795543986,
    "y": 45.630701447925134
}, 10);
```

Example configuration to change the value of JMAP\_OPTIONS.reportsBaseUrl based on a given URL.

```
if (window.location.href.includes("myjmap.com"))  {
      JMAP_OPTIONS.reportsBaseUrl = "http:/reports.myjmap.com/diffuser/2.0/";
      console.log('NG Configuration: Reports home changed to ' + JMAP_OPTIONS.reportsBaseUrl);
}
```
