Strapi plugin `map-field`

The map-field Strapi plugin allows to add a Mapbox map custom field in your content-types.

You can use the seach box to pinpoint the location you are looking for. Alternatively, you can double-click anywhere on the map, which will put a marker on the closest geolocated point.

The address, longitude and latitude of the geolocated point are displayed in the readonly fields underneath the map.

The field will actually be stored as GeoJSON in a JSON field behing the scene.

This plugin was inspired by

It uses the following npm packages

Install the plugin

To install this plugin, you need to add an NPM dependency to your Strapi application:

# Using Yarn
yarn add strapi-plugin-map-field

# Or using NPM
npm install strapi-plugin-map-field

Configure the plugin

You need to enable the plugin in your Strapi plugins configuration.

Open config/plugins.js and add the following:

// config/plugins.js
module.exports = ({ env }) => ({

  ...

  "map-field": {
    enabled: true,
  },

  ...

});

Update the security middleware configuration

In order for the map to be displayed properly, you will need to update the strapi::security middleware configuration.

For that, open config/middlewares.js and add the directive 'worker-src': ['blob:'] to the contentSecurityPolicy directives under strapi::security. You also need to add api.mapbox.com in the script-src.

The whole file should look somewhat like this:

module.exports = ({
  env
}) => [
  'strapi::errors',
  {
    name: 'strapi::security',
    config: {
      contentSecurityPolicy: {
        useDefaults: true,
        directives: {
          'connect-src': ["'self'", 'https:'],
          'script-src': ["'self'", "'unsafe-inline'", 'cdn.jsdelivr.net', 'api.mapbox.com'],
          'img-src': ["'self'", 'data:', 'blob:' ],
          'media-src': ["'self'", 'data:', 'blob:'],
          'worker-src': ['blob:'],
          upgradeInsecureRequests: null,
        },
      }
    },
  },
  'strapi::cors',
  'strapi::poweredBy',
  'strapi::logger',
  'strapi::query',
  'strapi::body',
  'strapi::session',
  'strapi::favicon',
  'strapi::public',
];
