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:

``json
{
"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.).

🚀 Strapi Configuration (required)

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

Instead of:

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

Write:

`js
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",
],
},
},
},
},
// ...
];
