Vue2Leaflet

Vue2Leaflet is a JavaScript library for the Vue framework that wraps Leaflet making it easy to create reactive maps.

Documentation

Go here to check out live examples and docs.

If you want to hack around, here is a JS Fiddle to get started

:warning: Breaking changes from v0.x.x to v1.x.x :warning:

A new major release v1.x.x is available and come with some breaking changes.

:exclamation: Components names

As some component where conflicting with reserved name like Circle with SVG Circle, from v1.x.x all components are prefixed with L.

For example Marker component became LMarker (l-marker in template).

:exclamation: Events names

Event handling have been simplified and are now mapped directly to Leaflet event.

For example Marker move event was 'l-move' and became simply 'move'.

:sparkles: Leaflet Controls

v1.0.0 introduces Leaflet Controls you can now use them using LControlAttribution, LControlLayers, LControlScale and LControlZoom.

When adding LControlAttribution or LControlZoom to your template, remember to desactivate the default one by using LMap options:

{
  zoomControl: false,
  attributionControl: false
}

Otherwise you will end up with two zoom/attribution control.

Leaflet Plugins

Leaflet plugins can easily work with Vue2Leaflet, if you want to use one I would recommand to look at the awesome work made by the community in the list below.

Vue2Leafet plugins:

• vue2-leaflet-markercluster wrapper for MarkerCluster
• vue2-leaflet-polylinedecorator wrapper for PolylineDecorator
• vue2-leaflet-googlemutant wrapper for GoogleMutant
• vue2-leaflet-tracksymbol wrapper for TrackSymbol
• vue-choropleth to display a choropleth map given a certain GeoJSON
• vue2-leaflet-geosearch wrapper for GeoSearch
• vue2-leaflet-vectorgrid wrapper for VectorGrid to display gridded vector data
• vue2-leaflet-rotatedmarker wrapper for RotatedMarker
• vue2-leaflet-editablecirclemarker wrapper for leaflet-editablecirclemarker
• vue2-leaflet-hotline wrapper for hotline

If you have created a plugin and want it to be listed here, let me know :-).

Vue2Leaflet is only a wrapper for Leaflet. I want to keep it as simple as possible so I don't want to add any plugin support into this repo.

FAQ

My map and/or markers don't fully render. What gives?

Depending on your project setup, you may have to try different solutions.

To fix map rendering issues, it may help to import the Leaflet stylesheet within the script section of your Vue component.

In most cases, though, it is Webpack messing with Leaflet marker icons' paths, resulting in warnings or even errors. You can alleviate that by either unsetting/replacing the default paths (alternate solution) or using Webpack aliases.

How can I access the Leaflet map object?

First add a ref to the map

  <l-map ref="map" :zoom=13 :center="[47.413220, -1.219482]">
    ...
  </l-map>

Then in you JavaScript you can use mapObject which is Leaflet map instance :

this.$refs.map.mapObject;

Note: mapObject is not available directly in vue's mounted hook. You need to wrap the call to this.$refs.map in a nextTick call:

data: () => ({map: null}),
mounted () {
  // DON'T
  this.map = this.$refs.map.mapObject // doesn't work, this.map is null

  // DO
  this.$nextTick(() => {
    this.map = this.$refs.map.mapObject // work as expected
  })
},

This also work for any other component (Marker, Polyline, etc...)

How can I bind events of Vue2Leaflet components?

All event binding can be done to event with the same name as in leaflet documentation.

For example if you want to listen to Vue2Leaflet.LMarker move event.

<l-marker :lat-lng="[47.413220, -1.219482]" @move="doSomething"></l-marker>
