Getting Started

Init Leaflet-Geoman

Just include leaflet-geoman.min.js right after Leaflet. It initializes itself. If
you want certain layers to be ignored by Leaflet-Geoman, pass pmIgnore: true to
their options when creating them. Example:

L.marker([51.50915, -0.096112], { pmIgnore: true }).addTo(map);  

Enable Leaflet-Geoman on an ignored layer:

layer.setStyle({pmIgnore: false});
// layer.options.pmIgnore = false; // If the layer is a LayerGroup / FeatureGroup / GeoJSON this line is needed too
L.PM.reInitLayer(layer);  

If Opt-In (look below) is true, a layers pmIgnore property has to be set to false to get initiated.

Opt-In

If you want to use Leaflet-Geoman as opt-in, call the following function right after importing:

L.PM.setOptIn(true);

And to disable it:

L.PM.setOptIn(false);

If you have enabled opt-in before you init the map, you need to specify pmIgnore: false in the map options:

const map = L.map('map', { pmIgnore: false });

All layers will be ignored by Leaflet-Geoman, unless you specify pmIgnore: false on a layer:

L.marker([51.50915, -0.096112], { pmIgnore: false }).addTo(map);

Newly drawn layers will be ignored as well.

To prevent this you can add the following event handler:

map.on('pm:create', (e) => {
  e.layer.setStyle({ pmIgnore: false });
  L.PM.reInitLayer(e.layer);
});

Leaflet-Geoman Toolbar

You can add a toolbar to the map to use Leaflet-Geoman features via a user interface.

// add Leaflet-Geoman controls with some options to the map  
map.pm.addControls({  
  position: 'topleft',  
  drawCircle: false,  
});  

The following methods are available on map.pm:

To pass options to the buttons you have two ways:

// make polygon not snappable during draw  
map.pm.enableDraw('Polygon',{ snappable: false }); 
map.pm.disableDraw();

// make all layers not snappable during draw  
map.pm.setGlobalOptions({ snappable: false }); 

The options will persist, even when the mode is enabled/disabled via the toolbar.

All available options for drawing and editing are specified in the sections below.

Draw Mode

Use Draw Mode on a map like this:

// enable polygon Draw Mode
map.pm.enableDraw('Polygon', {

You can listen to map events to hook into the drawing procedure like this:

map.on('pm:drawstart', (e) => {
  console.log(e);
});

Here's a list of map events you can listen to:

Event	Params	Description	Output
pm:globaldrawmodetoggled	e	Fired when Drawing Mode is toggled.	enabled, shape, map
pm:drawstart	e	Called when Draw Mode is enabled. Payload includes the shape type and working layer.	shape, workingLayer
pm:drawend	e	Called when Draw Mode is disabled. Payload includes the shape type.	shape
pm:create	e	Called when a shape is drawn/finished. Payload includes shape type and the drawn layer.	shape, layer

There are also several events for layers during draw. Register an event like this:

// listen to vertexes being added to currently drawn layer (called workingLayer)
map.on('pm:drawstart', ({ workingLayer }) => {
  workingLayer.on('pm:vertexadded', (e) => {
    console.log(e);
  });
});

Here's a list of layer events you can listen to:

Event	Params	Description	Output

For making the snapping to other layers selective, you can add the "snapIgnore" option to your layers to disable the snapping to them during drawing.

//This layer will be ignored by the snapping engine during drawing
L.geoJSON(data, {
  snapIgnore: true,
});

Options

You have many options available when drawing and editing your layers (described above).
You can set the options per layer as described above, or you can set them globally for all layers. This is especially useful when you use the toolbar and can't change the options programmatically.

Examples:

layer.pm.enable({ pinning: true, snappable: false });

map.pm.setGlobalOptions({ pinning: true, snappable: false });

The following options are additionally to the Draw and Edit Mode options.

Option	Default	Description
snappingOrder	Array	Prioritize the order of snapping. Default: ['Marker','CircleMarker','Circle','Line','Polygon','Rectangle'].
layerGroup	map	add the created layers to a layergroup instead to the map.
panes	Object	Defines in which panes the layers and helper vertices are created. Default: { vertexPane: 'markerPane', layerPane: 'overlayPane', markerPane: 'markerPane' }.

Some details about a few more powerful options:

Snapping

Snap the dragged marker/vertex to other layers for precision drawing.
Snapping can be disabled for layers with the layer option snapIgnore: true. With snapIgnore: false it will be always snappable, also if pmIgnore is set. Can also be disabled by holding the ALT key.

Pinning ⭐

When dragging a vertex/marker, you can pin all other Markers/Vertices that have the same latlng to the dragged marker. Exclusive for Leaflet-Geoman Pro ⭐
