Installation
npm install hslayers-ng-appCreate empty html page and include <hslayers-app></hslayers-app> Where you want the map to appear.
Include hslayers-ng styles in page <head>:
<link rel="stylesheet" href="node_modules/hslayers-ng-app/styles.css">Include hslayers-ng-app bundle scripts:
<script src="node_modules/hslayers-ng-app/runtime.js"></script>
<script src="node_modules/hslayers-ng-app/polyfills-es5.js"></script>
<script src="node_modules/hslayers-ng-app/polyfills.js"></script>
<script src="node_modules/hslayers-ng-app/vendor.js"></script><!-- Must be included since 4.x -->
<script src="node_modules/hslayers-ng-app/main.js"></script>Configuration
A global hslayersNgConfig function, which returns a configuration object, NEEDS TO BE CREATED BEFORE loading the main.js script (insert it before the bundle script in the html). It returns a JSON object that describes the application's looks, behavior and data to display. See Configuration options for the list of available config options. HSLayers-ng exposes OpenLayers as global 'ol' variable, which is used in defining layers and configuration.
<script>
function hslayersNgConfig(ol) {
return {
assetsPath: 'node_modules/hslayers-ng-app/assets/',
default_layers: [
new ol.layer.Tile({
source: new ol.source.OSM(),
title: "OpenStreetMap",
base: true,
visible: true,
removable: false
})
],
default_view: new ol.View({
center: ol.proj.fromLonLat([17.474129, 52.574000]),
zoom: 4,
})
}
}
</script>Multiple apps setup
Built-in option for bootstrapping multiple app instances can be utilized by simply creating (and styling) desired number of hslayers-app elements including with ids
<html>
...
<hslayers-app id="app-a"></hslayers-app>
<hslayers-app id="app-b"></hslayers-app>
...
</html>and creating hslayersNgConfig function which name would include corresponding id string such as
<script>
function hslayersNgConfigapp-a(ol) {
...
}
</script>In case no exact match between app id and config name is found, the app tries to call default function i.e. hslayersNgConfig
