README

Render map widgets using Leaflet.

• Support for multiple maps on the same page
• Built-in actions: CenterMapAction, ZoomAction, FullpageAction and , FullscreenAction
• Add Filament Actions directly on the as map control buttons
• Multiple layers support. A DarkModeTile layer is included.
• Marker clustering support

Note For Filament 2.x use 2.x branch

Installation

composer require webbingbrasil/filament-maps

Usage

Create a widget class and extend Webbingbrasil\FilamentMaps\Widgets\MapWidget:

use Webbingbrasil\FilamentMaps\Actions;
use Webbingbrasil\FilamentMaps\Marker;
use Webbingbrasil\FilamentMaps\Widgets\MapWidget;

class Map extends MapWidget
{
    protected int | string | array $columnSpan = 2;
    
    protected bool $hasBorder = false;

    public function getMarkers(): array
    {
        return [
            Marker::make('pos2')->lat(-15.7942)->lng(-47.8822)->popup('Hello Brasilia!'),
        ];
    }

    public function getActions(): array
    {
        return [
            Actions\ZoomAction::make(),
            Actions\CenterMapAction::make()->zoom(2),
        ];
    }
}

If you create a new widget using the make:filament-widget command, remember to remove the view created along with it otherwise the map will not be rendered.

Map Configuration

For some configuration its possible to use properties:

• $mapOptions: array with options available on Leaftlet. See Leaflet documentation for more details.
• $tileLayerUrl: string or array with tile layer url`s. Default to OpenStreetMap.
• $hasBorder: show a border around the map. Default is true.
• $rounded: show a rounded border around the map. Default is true.
• $height: height of the map. Default is 400px.
• $heading: set the heading of the map.
• $footer: set the footer of the map.
• $fullpage: show the map in fullpage mode. Default is false.

But you can also use the setUp method if you need more control:

public function setUp(): void
{
    $this
        ->tileLayerUrl(...)
        ->height(..)
        ->rounded(..)
        ->mapOptions(..)
        ->mapMarkers([
            ...
        ])
        ->fitBounds([
            [lat, lng],
            [lat, lng]
            ...
        ])
        ->actions([
            ..
        ]);
}

The setUp method is called on mount of the widget. See livewire lifecycle hooks for more information.

Global Configuration

If you want to set a default configuration for all instances of the map widget, you can use the configureUsing method in a service provider:

MyMap::configureUsing(function (ResellerMap $widget) {
    $widget->mapMarkers([
        Marker::make('id')
            ->lat(51.505)
            ->lng(-0.09)
            ->popup('I am a popup')
            ->tooltip('I am a tooltip'),
    ])
    ->tileLayerUrl('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png')
    ->tileLayerOptions([
        'attribution' => 'Map data © <a href="https://openstreetmap.org">OpenStreetMap</a> contributors',
    ])
});

Tile Layers

The map uses OpenStreetMap tiles by default, but you can change it to use any other provider using $tileLayerUrl property or tileLayerUrl method. It's recommended to also use the tileLayerOptions to set correct attributions.

Multiple Tile Layers

You can also use multiple tile layers:

protected string | array  $tileLayerUrl = [
    'OpenStreetMap' => 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
    'OpenTopoMap' => 'https://{s}.tile.opentopomap.org/{z}/{x}/{y}.png'
];

protected array $tileLayerOptions = [
    'OpenStreetMap' => [
        'attribution' => 'Map data © <a href="https://openstreetmap.org">OpenStreetMap</a> contributors',
    ],
    'OpenTopoMap' => [
        'attribution' => 'Map data © <a href="https://openstreetmap.org">OpenStreetMap</a> contributors, SRTM | Map style © <a href="https://opentopomap.org">OpenTopoMap</a> (<a href="https://creativecommons.org/licenses/by-sa/3.0/">CC-BY-SA</a>)',
    ],
];

And you can use a action to change the tile layer:

Actions\Action::make('mode')
                ->icon('filamentmapsicon-o-square-3-stack-3d')
                ->callback('setTileLayer(mode === "OpenStreetMap" ? "OpenTopoMap" : "OpenStreetMap")'),

Dark Mode

If you want to use a dark mode tile layer, you can use the HasDarkModeTiles trait. This trait will automatically set two tiles layers and listen Filament dark-mode-toggled event. You can change the default tile layers using the $lightModeTileLayerUrl and $darkModeTileLayerUrl properties.

Actions

You can add actions to the map widget. Actions are buttons that can be clicked to perform an action using a JS callback. You can create your own actions or use the ones provided by the package.

Zoom Action

The ZoomAction action will add a button to the map that will zoom in or out the map. You can set the zoom level using the zoom() method:

use Webbingbrasil\FilamentMaps\Actions;
Actions\ZoomAction::make()->zoom(2), // Zoom in/out 2 levels

Center Map Action

This action will center the map on a specific position.

use Webbingbrasil\FilamentMaps\Actions;

public function getActions(): array
{
    return [
        Actions\CenterMapAction::make()->centerTo([51.505, -0.09])->zoom(13),
    ];
}

You can also center the map on user position:

Actions\CenterMapAction::make()->centerOnUserPosition()->zoom(13)

Note: The center on user position feature will only work if the user browser supports Navigator.geolocation. Also, the user must be on a secure context (HTTPS) and needs to allow access to the location.

Fit Bounds

You can use fitBounds() to adjusts the zoom level and center of the map to show a given geographical area

Actions\CenterMapAction::make()->fitBounds([
   [lat, lng],
   [lat, lng],
])

You can pass multiple points to be used in fitBounds or use the initial bounderies configured in setUp()

public function setUp(): void
{
    $this->fitBounds([
        [lat, lng],
        [lat, lng],
        ...
    ]);
}

public function getActions(): array
{
    return [
        CenterMapAction::make()->fitBounds($this->getFitBounds()),
    ];
}

Full Page or Full Screen Action

You can add a button to the map to show it in full page or full screen mode.:

use Webbingbrasil\FilamentMaps\Actions;
Actions\FullpageAction::make()
Actions\FullscreenAction::make()

Custom Action

You can create your own actions using Webbingbrasil\FilamentMaps\Actions\Action.

For example, a action to add new markers:

use Webbingbrasil\FilamentMaps\Actions;

Actions\Action::make('form')
        ->icon('filamentmapsicon-o-arrows-pointing-in')
        ->form([
            Forms\Components\TextInput::make('name')
                ->label('Name')
                ->required(),
            Forms\Components\TextInput::make('lat')
                ->label('Latitude')
                ->required(),
            Forms\Components\TextInput::make('lng')
                ->label('Longitude')
                ->required(),
        ])
        ->action(function (array $data, self $livewire) {
            $livewire
                ->addMarker(
                    Marker::make(Str::camel($data['name']))
                        ->lat($data['lat'])
                        ->lng($data['lng'])
                        ->popup($data['name'])
                )
                ->centerTo(location: [$data['lat'], $data['lng']], zoom: 13)
        })

In this example we use addMarker() method to add a new marker dynamically and centerTo() to set new map center and zoom level.

You can manipulate markers data using:

$liveWire->mapMarkers(array $markers); // update the markers
$livewire->addMarker(Marker $marker); // add a new marker
$livewire->removeMarker(string $id); // remove a marker
$livewire->updateMarker(string $id, Marker $marker); // update a marker

Note: Markers need to have a unique name. If you try to add a marker with the same name as an existing one, the existing one will be replaced.

Using JS

This approach is useful if you want to use a custom javascript to manipulate the map without using Livewire.

Actions\Action::make('center')
    ->alpineClickHandler(<<<JS
        map.setView([0,0], 2)
    JS)

Use map property to access the Leaflet instance on your action handler.

Action Position

You can set the position of the action using position() method:

$this
    ->actions([
        Actions\CenterMapAction::make()->position('topright'),
    ])
}

Action Icon

You can set the icon of the action using icon() method:

Actions\Action::make()->icon('heroicon-o-home')

Markers

You can add markers to the map widget. Markers are points on the map that can be clicked to open a info popup or execute a JS callback.

use Webbingbrasil\FilamentMaps\Marker;

$this
    ->mapMarkers([
        Marker::make('id')
            ->lat(51.505)
            ->lng(-0.09)
            ->popup('I am a popup'),
        Marker::make('id')
            ->lat(51.505)
            ->lng(-0.09)
            ->tooltip('I am a tooltip')
            ->callback(<<<JS
                alert('Hello World!');
            JS),
    ])
}

The callback method is called during the rendering of the marker and must return a JS that will be executed on event click. Use map to access the Leaflet instance in your callback.

Marker Cluster

You can use the MarkerCluster class to group markers in clusters. This is useful if you have a lot of markers on the map.

use Webbingbrasil\FilamentMaps\MarkerCluster;

$this
    ->mapMarkers([
        MarkerCluster::make([
            Marker::make('id')
                ->lat(51.505)
                ->lng(-0.09)
                ->popup('I am a popup'),
            Marker::make('id')
                ->lat(51.505)
                ->lng(-0.09)
                ->tooltip('I am a tooltip')
                ->callback(<<<JS
                    alert('Hello World!');
                JS),
        ]),
    ])
}

Marker Icon Color

You can set the color of the marker icon using color() method:

Marker::make('id')
    ->color(Marker::COLOR_RED)

See the Marker::COLOR_* constants for all available colors. Default color is Marker::COLOR_BLUE.

Marker Custom Icon

You can set a custom icon for the marker using icon() method:

Marker::make('id')
    ->icon(
        string $iconUrl,
        string $shadowUrl,
        array $iconSize,
        array $iconAnchor,
        array $popupAnchor,
        array $shadowSize
    )

You can get extra icons and reledate config from leaflet-color-markers

Display Marker Details

At the time, markers do not have the same functionality as Actions but using livewire events you can do something similar, for example:

Add a callback to yout marker:

Marker::make('place')->callback('Livewire.emit("updateFooter", ' . $placeId . ')');

Register event listener in map widget:

protected $listeners = ['updateFooter' => 'showMarkerData'];

public function showMarkerData($placeId)
{
    $place = Place::find($placeId);
    $this->footer = view('marker-details', $place);
}

Polylines

You can add polylines to the map widget. Polylines are lines on the map drawn on the map between two lat/lng points. If your have multiple polylines, each polyline must have an unique name.

public function getPolylines(): array
{
    return [
        Polyline::make('polyline')
        ->latlngs([
            [45.51, -122.68],
            [37.77, -122.43],
            [34.04, -118.2]
        ])->options(['color' => 'blue', 'weight' => 5])
        ->tooltip('I am a tooltip')
        ->popup('I am a popup'),
    ];
}

You can use options listed at Leaflet Polyline options

Polylines actions

You can use actions as described above to manipulate polylines:

Actions\Action::make('add line')
    ->tooltip('Add line')
    ->icon('filamentmapsicon-o-map-pin')
    ->form([
        Forms\Components\TextInput::make('name')
            ->label('Name')
            ->required(),
        Forms\Components\Section::make('Start')
            ->schema([
                Forms\Components\TextInput::make('lat1')
                    ->label('Latitude')
                    ->required(),
                Forms\Components\TextInput::make('lng1')
                    ->label('Longitude')
                    ->required(),
            ]),
        Forms\Components\Section::make('End')
            ->schema([
                Forms\Components\TextInput::make('lat2')
                    ->label('Latitude')
                    ->required(),
                Forms\Components\TextInput::make('lng2')
                    ->label('Longitude')
                    ->required(),
            ]),
    ])
    ->action(function (array $data, self $livewire) {
        $livewire
            ->addPolyline(
                Polyline::make(Str::camel($data['name']))
                    ->latlngs([
                        [$data['lat1'], $data['lng1']],
                        [$data['lat2'], $data['lng2']]
                    ])
            );
    })

In this example we use addPolyline() method to add a new polyline dynamically. You can also use removePolyline() and updatePolyline() methods.

$livewire->addPolyline(Polyline::make('polyline-name')->latlngs([...])->options([..]));
$livewire->removePolyline('polyline-name');
$livewire->updatePolyline(Polyline::make('polyline-name')->latlngs([...])->options([...]));

Polygones

You can add polygones to the map widget. Polygones are lines on the map drawn on the map between two lat/lng points. If your have multiple polygones, each polygone must have an unique name.

public function getPolylgones(): array
{
    return [
        Polygone::make('polygone')
        ->latlngs([
            [45.51, -122.68],
            [37.77, -122.43],
            [34.04, -118.2]
        ])->options(['color' => 'blue', 'weight' => 5])
        ->tooltip('I am a tooltip')
        ->popup('I am a popup'),
    ];
}

You can use options listed at Leaflet Polygone options

Polygones actions

$livewire->addPolygone(Polygone::make('polygone-name')->latlngs([...])->options([..]));
$livewire->removePolygone('polygone-name');
$livewire->updatePolygone(Polygone::make('polygone-name')->latlngs([...])->options([...]));

Rectangles

You can add rectangles to the map widget. If your have multiple rectangles, each rectangle must have an unique name.

public function getRectangles(): array
{
    return [
            Rectangle::make('rectangle')
                ->bounds([
                    [54.559322, -5.767822],
                    [56.1210604, -3.021240]
                ])->tooltip('rectangle')
                ->options(['color' => 'red'])
    ];
}

You can use options listed at Leaflet Rectangle options

Rectangles actions

$livewire->addRectangle(Polygone::make('rectangle-name')->bounds([...])->options([..]));
$livewire->removeRectangle('rectangle-name');
$livewire->updateRectangle(Polygone::make('rectangle-name')->bounds([...])->options([...]));

Circles

You can add circles to the map widget. If your have multiple circles, each circle must have an unique name.

public function getCircles(): array
{
    return [
            Circle::make('circle')
                ->lat(-15.7942)
                ->lng(-47.8822)
                ->options(['radius' => 200000])
                ->popup('Hello Brasilia!')
                ->tooltip('test2'),
    ];
}

You can use options listed at Leaflet Circle options

Rectangles actions

$livewire->addCircle(Circle::make('circle-name')->lat(...)->lng(...)->options([..]));
$livewire->removeCircle('circle-name');
$livewire->updateCircle(Circle::make('circle-name')->lat(...)->lng(...)->options([...]));
