Maplibre GL
This module provides integration with MapLibre GL JS, an open-source fork of Mapbox GL JS. It allows developers to create interactive maps using API calls, specifying map styles, data sources, and visual controls. Maps can display geographic data, including GeoJSON and vector tiles, and can be configured to show layer properties in popups or separate content areas.
Due to the changes of mapbox terms of use. This is a fork of module https://www.drupal.org/project/mapbox_gl/ to use maplibre instead of mapbox , more to read in https://www.maptiler.com/news/2021/01/maplibre-mapbox-gl-open-source-fork/ and https://maplibre.org/maplibre-gl-js/docs/
Initial code for integration with Maplibre GL JS.
This is an API only module. There is no UI. Maps can be generated using hook_maplibre_gl_info() and calling the render method.
popup should either be "popup" to display the layer properties in a popup, or the ID of a separate element in which to display the information. e.g. "my-properties-div".
"My Locations" in the example below is a tile set created within Mapbox Studio (or uploaded). The URL includes the "Map ID" found on the Tileset's page.
e.g.
function hook_maplibre_gl_map_info() {
// For options, see: https://maplibre.org/maplibre-gl-js/docs/API/

}
To display the map:
use Drupal\maplibre_gl\Controller\MaplibreGlController;
$map = MaplibreGlController::renderMap('Streets');
Drupal Content as Source Data
To use Drupal content as source data for a layer, create a path with Maplibre compatible output. For example, create a View with GeoJSON output.
