Installation

Migrate from Leaflet.PM

npm uninstall leaflet.pm  
npm i @geoman-io/leaflet-geoman-free  

That's it.

Install via npm

npm i @geoman-io/leaflet-geoman-free  

Install Manually

Download
leaflet-geoman.css and
leaflet-geoman.min.js
and include them in your project.

Include via CDN

JS

<script src="https://unpkg.com/@geoman-io/[email protected]/dist/leaflet-geoman.min.js"></script>  

Include as ES6 Module

import '@geoman-io/leaflet-geoman-free';  
import '@geoman-io/leaflet-geoman-free/dist/leaflet-geoman.css';  

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.options.pmIgnore = false;
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);  

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);  

leaflet-geoman Toolbar

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:

Method Returns Description
addControls(options) - Adds the Toolbar to the map. The options are optional.
removeControls() - Removes the Toolbar from the map.
toggleControls() - Toggle the visiblity of the Toolbar.
controlsVisible() Boolean Returns true if the Toolbar is visible on the map.

See the available options in the table below.

Option Default Description
position 'topleft' toolbar position, possible values are 'topleft', 'topright', 'bottomleft', 'bottomright'
positions Object the position of each block (draw, edit, custom, options⭐) can be customized. If not set, the value from position is taken. Default: {draw: '', edit: '', options: '', custom: ''} Block Position
drawMarker true adds button to draw Markers
drawCircleMarker true adds button to draw CircleMarkers
drawPolyline true adds button to draw Line
drawRectangle true adds button to draw Rectangle
drawPolygon true adds button to draw Polygon
drawCircle true adds button to draw Circle

drawControls true shows all draw buttons / buttons in the draw block
editControls true shows all edit buttons / buttons in the edit block
customControls true shows all buttons in the custom block
optionsControls true shows all options buttons / buttons in the option block ⭐
pinningOption true adds a button to toggle the Pinning Option ⭐
snappingOption true adds a button to toggle the Snapping Option ⭐

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', {  
  snappable: true,  
  snapDistance: 20,  
});  
  
// disable draw mode  
map.pm.disableDraw();

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 drawing mode is enabled. Payload includes the shape type and working layer shape, workingLayer
pm:drawend e Called when drawing 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
pm:vertexadded e Called when a new vertex is added. Payload includes the new vertex, it's marker, index, working layer and shape type shape, workingLayer, marker, latlng
pm:snapdrag e Fired during a marker move/drag. Payload includes info about involved layers and snapping calculation. shape, distance, layer = workingLayer, marker, layerInteractedWith, segment, snapLatLng

pm:centerplaced e Called when the center of a circle is placed/moved. shape, workingLayer, latlng

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
});

Edit Mode

You can enable Edit Mode for all layers on a map like this:

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 programatically.

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.

Snapping Options

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 ⭐

Pinning Option

Measurement ⭐

Calculates the measurement of a layer while drawing and editing. Exclusive for Leaflet-Geoman Pro ⭐

map.pm.setGlobalOptions({ measurements: { measurement: true, displayFormat: 'metric', ... } })

See the available options in the table below.

Option Default Description
measurement true Enable measurement calculation
showTooltip true Shows the tooltip during draw and edit
showTooltipOnHover true Shows the tooltip when hovering a finished layer

Customize

Customize Language

Change the language of user-facing copy in leaflet-geoman

map.pm.setLang('de');  

Currently available languages are da, de, el, en, es, fa, fr, hu, id, it, nl, no, pl, pt_br, ro, ru, sv, tr, ua, zh and zh_tw.
To add translations to the plugin, you can add a translation file via Pull Request.

You can also provide your own custom translations.

const customTranslation = {  
  tooltips: {  
    placeMarker: 'Custom Marker Translation',  
  }
};  
  
map.pm.setLang('customName', customTranslation, 'en');  

The 3rd parameter is the fallback language in case you only want to override a few Strings.
See the english translation file for all available strings.

The following events are available on a map instance:

Event Params Description Output
pm:langchange e Fired when language is changed activeLang, oldLang, fallback, translations

Customize Style

To customize the style of the drawn layer with leaflet options, you can either
pass the options to enableDraw or set the options generally:

map.pm.setPathOptions({  
  color: 'orange',  
  fillColor: 'green',  
  fillOpacity: 0.4,  
});  

If you want to exclude shapes from receiving these path options, use the second parameter like this:

map.pm.setPathOptions({color: 'orange'}, {
  ignoreShapes: ['Circle', 'Rectangle']  
});  

Toolbar

The following methods are available on map.pm.Toolbar:

Method Returns Description
changeControlOrder(order) - Pass an array of button names to reorder the buttons in the Toolbar
getControlOrder() Array Current order of the buttons in the Toolbar
setBlockPosition(block,position) - The position of a block (draw, edit, custom, options⭐) in the Toolbar can be changed. If not set, the value from position of the Toolbar is taken. Details
getBlockPositions() Object Returns a Object with the positions for all blocks
createCustomControl(options) - To add a custom Control to the Toolbar. Details
copyDrawControl(instance, options) Object Creates a copy of a draw Control. Returns the drawInstance and the control.
changeActionsOfControl(name, actions) - Change the actions of an existing button.

Customize Controls

There are 4 control blocks in the Toolbar: draw, edit, custom and options
You can disable / enable entire blocks. To display the Toolbar as one block instead of 4, use oneBlock: true.

map.pm.addControls({  
 drawControls: true, 
 editControls: false, 
 optionsControls: true, 
 customControls: true, 
 oneBlock: false 
})

Reorder the buttons with

map.pm.Toolbar.changeControlOrder(['drawCircle', 'drawRectangle', 'removalMode', 'editMode']);  

Receive the current order with

map.pm.Toolbar.getControlOrder();  

Toolbar Block Position

You can set different positions per block draw, edit, options⭐, custom:

Possible values are 'topleft', 'topright', 'bottomleft', 'bottomright'

map.pm.addControls({  
  positions: {  
    draw: 'topright',  
    edit: 'topleft',  
  }
});  
map.pm.Toolbar.setBlockPosition('draw','topright');  
map.pm.Toolbar.getBlockPositions();  

Adding New/Custom Controls

// add a new custom control  
map.pm.Toolbar.createCustomControl(options)  
Option Default Description
name Required Name of the control
block '' block of the control. draw, edit, custom, options
title '' Text showing when you hover the control
className '' CSS class with the Icon
onClick - Function fired when clicking the control
afterClick - Function fired after clicking the control
actions [ ] Action that appears as tooltip. Look under Actions for more information
toggle true Control can be toggled
disabled false Control is disabled

Inherit from an Existing Control

This effectively copies an existing control that you can customize.

// copy a rectangle and customize its name, block, title and actions  
map.pm.Toolbar.copyDrawControl('Rectangle',{  
  name:'RectangleCopy',  
  block: 'custom',  
  title: 'Display text on hover button',  
  actions: actions  
});  

Actions

You can add your own actions to existing or custom buttons.

Here, we configure 3 separate actions in an array.

// creates new actions  
const actions = [ 
  // uses the default 'cancel' action 
  'cancel',    
  // creates a new action that has text, no click event  
  { text: 'Custom text, no click' },  
  // creates a new action with text and a click event 
  { text: 'click me', onClick: () => { alert('🙋‍♂️') }  
}]  

Default actions available are: cancel, removeLastVertex, finish, finishMode.

Change actions of an existing button:

map.pm.Toolbar.changeActionsOfControl('Rectangle', actions)  

Pass actions to your custom buttons through the actions property mentioned under Inherit from an Existing Control

The following events are available on a map instance:

Event Params Description Output

Credit

As I never built a leaflet plugin before, I looked heavily into the code of
leaflet.draw to find out how to do stuff. So don't be surprised to see some
familiar code.

I also took a hard look at the great
L.GeometryUtil for some
of my helper functions.
