Strapi-Leaflet-Geoman

A Strapi plugin allowing you to implement a Leaflet-Geoman custom field into your content-types, which can be used to pick and retrieve locations.

✨ Usage

The API response of a Strapi content-type implementing this leaflet-geoman custom field could look as follows:

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": {
        "type": "Point | Polygon | MultiLineString | LineString",
          "coordinates": [-104.99404, 39.75621]
      },
      "properties": {
      	"style": {
          "color": "#059669",
          "weight": 8
        },
      }
    }
  ]
}

You can configure globally this plugin inside your Strapi dashboard's settings tab (e.g. to enter leaflet tile url, attribution etc.).

Also plugin can be configured per collection entity.

Now you can use Strapi Leaflet Geoman as a custom field.

🚀 Strapi Configuration (required)

Allow all Google Maps assets to be loaded correctly by customizing the strapi::security middleware inside ./config/middlewares.js.

Instead of:

export default [
  // ...
  'strapi::security',
  // ...
];

Write:

export default [
  // ...
  {
    name: 'strapi::security',
    config: {
      contentSecurityPolicy: {
        useDefaults: true,
        directives: {
          "connect-src": ["'self'", "https:"],
          "script-src": [
            "'self'",
            "unsafe-inline",
            "https://*.basemaps.cartocdn.com",
          ],
          "media-src": [
            "'self'",
            "blob:",
            "data:",
            "https://*.basemaps.cartocdn.com",
            "https://tile.openstreetmap.org",
          ],
          "img-src": [
            "'self'",
            "blob:",
            "data:",
            "https://*.basemaps.cartocdn.com",
            "market-assets.strapi.io",
            "https://tile.openstreetmap.org",
