Usage

This component extends the Angular 2 Leaflet component by adding directives for activating and configuring the Filter plugin for Leaflet.

Use the leaflet-filter attribute directive in conjunction with the leaflet attribute directive to activate a map and enable the filter control.

<div leaflet style="height: 400px;"
     leafletFilter
     [leafletOptions]="options"
     [leafletFilterOptions]="filterOptions"
     [(leafletFilterState)]="filterState"
     (leafletFilterStateChange)="eventHandler('filterChanged', $event)">

API

leafletFilter

Attribute directive that activates the Leaflet filter plugin.

leafletFilterOptions

Input binding for Filter control options.

The Filter Control options extend the standard control options.

Example:

var filterOptions = {
    position: 'topright',
    filter: {
        rectangle: {},
        polygon: {},
        circle: {},
    },
    featureGroup: featureGroup
};

featureGroup

You may choose to provide your own featureGroup layer to the plugin. This is the layer in which the plugin will place all drawn filter shapes. If you specify the featureGroup, it's your job to make sure it's added to the map. If you don't specify a featureGroup, the component will create one for you.

var featureGroup = L.featureGroup();
featureGroup.addTo(map);

var options = {
    featureGroup: featureGroup
};

position

Determines the position on the map where the control will be placed.

Possible values: 'topright' | 'topleft' | 'bottomleft' | 'bottomright'

filter

Used to configure the various filter types.

Possible properties: circle | rectangle | polygon

If you omit the filter object entirely, all filter types will be enabled by default.

// All filter types enabled
var filterOptions = {
    position: 'topright'
};

Alternatively, if you only specify a subset of the filter types, only those specified will be enabled.

// Only circle and rectangle are enabled
var filterOptions = {
    position: 'topright',
    filter: {
        circle: {},
        rectangle: {}
    }
};

leafletFilterState

Binds the current filter state. Can be one of a circle, rectangle, polygon, or null if there is no active filter.
