// .scss
@import '~mapbox-gl/dist/mapbox-gl.css';
@import '~@lmc-eu/lmc-maps/dist/lmc-maps.css';

Import LmcMaps module and create new map:

// .js

(() => {
    new LmcMaps({
        container: 'lmcMapId',
        zoom: 7,
        center: [15.520, 49.760],
        coords: [[15.524, 49.766], [15.481, 49.758]],
        hasMarker: true,
        hasInteractivePois: true,
        lang: 'cs',
        // Tileserver running on default publicUrl require use of authToken. For demonstration and development purposes only, you can however override default publicUrl to use our "demo tileserver":
        publicUrl: 'https://tileserver.lmc.cz/demo' // DO NOT USE demo tileserver on production! (It has low rate limit.)
        // authToken is not needed for "demo tileserver" but must be defined for production use:
        // authToken: 'YOUR_TOKEN' // DO NOT FORGET to define auth token for production use
    });
})();

Tileserver publicUrl and authToken

Default tileserver publicUrl is set to https://tileserver.lmc.cz, but this tilserver can only be used with your own authToken.

If you don't have authToken yet (for example during development), you can use demo tileserver by setting publicUrl to https://tileserver.lmc.cz/demo. This tileserver does not need authToken, but it has low rate limit for tiles requests and thus must not be used on production.

For production use you need to set authToken and use production tileserver (for example https://tileserver.lmc.cz - which is also default, so you can omit defining publicUrl entirely).

If you run your own tileserver, you can set tileserver path in publicUrl option, e.g. http://localhost:8080 for your local tileserver.
