A few words on diversity in tech

I need to take some of your time. I can't believe we let shit like the Kathy Sierra incident or what happened to Brianna Wu happen over and over again. I can't believe we, the open source community, let sexist, misogynous shit happen over and over again.

I strongly believe that it is my — and your — duty to make the open source community, as well as the tech community at large, a community where everyone feel welcome and is accepted. At the very minimum, that means making sure the community and its forums both are safe, and are perceived as safe. It means being friendly and inclusive, even when you disagree with people. It means not shrugging off discussions about sexism and inclusiveness with handwaving about censorship and free speech. For a more elaborate document on what that means, the NPM Code of Conduct is a good start, Geek Feminism's resources for allies contains much more.

While I can't force anyone to do anything, if you happen to disagree with this, I ask of you not to use any of the open source I have published. Nor am I interested in contributions from people who can't accept or act respectfully towards other humans regardless of gender identity, sexual orientation, disability, ethnicity, religion, age, physical appearance, body size, race, or similar personal characteristics. If you think feminism, anti-racism or the LGBT movement is somehow wrong, disturbing or irrelevant, I ask you to go elsewhere to find software.

Leaflet Control Geocoder

A simple geocoder for Leaflet that by default uses OSM/Nominatim.

The plugin supports many different data providers:

The plugin can easily be extended to support other providers. Current extensions:

DAWA Geocoder - support for Danish Address Web API by Niels Kjøller Hansen

See the Leaflet Control Geocoder Demo.

Usage

Download latest release, or obtain the latest release via unpkg.com:

<link rel="stylesheet" href="https://unpkg.com/leaflet-control-geocoder/dist/Control.Geocoder.css" />
<script src="https://unpkg.com/leaflet-control-geocoder/dist/Control.Geocoder.js"></script>

Add the control to a map instance:

var map = L.map('map').setView([0, 0], 2);
L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);
L.Control.geocoder().addTo(map);

Customizing

By default, when a geocoding result is found, the control will center the map on it and place a marker at its location. This can be customized by listening to the control's markgeocode event. To remove the control's default handler for marking a result, set the option defaultMarkGeocode to false.

For example:

var geocoder = L.Control.geocoder({
        defaultMarkGeocode: false
    })
    .on('markgeocode', function(e) {
        var bbox = e.geocode.bbox;
        var poly = L.polygon([
             bbox.getSouthEast(),
             bbox.getNorthEast(),
             bbox.getNorthWest(),
             bbox.getSouthWest()
        ]).addTo(map);
        map.fitBounds(poly.getBounds());
    })
    .addTo(map);

This will add a polygon representing the result's boundingbox when a result is selected.

API

L.Control.Geocoder

This is the geocoder control. It works like any other Leaflet control, and is added to the map.

Constructor

This plugin supports the standard JavaScript constructor (to be invoked using new) as well as the class factory methods known from Leaflet:

new L.Control.Geocoder(options)
// or
L.Control.geocoder(options)

Options

Option	Type	Default	Description
`collapsed`	Boolean	`true`	Collapse control unless hovered/clicked
`expand`	String	`"touch"`	How to expand a collapsed control: `touch` or `click` or `hover`
`position`	String	`"topright"`	Control position
`placeholder`	String	`"Search..."`	Placeholder text for text input
`errorMessage`	String	`"Nothing found."`	Message when no result found / geocoding error occurs
`geocoder`	IGeocoder	`new L.Control.Geocoder.Nominatim()`	Object to perform the actual geocoding queries
`showResultIcons`	Boolean	`false`	Show icons for geocoding results (if available); supported by Nominatim

Methods

Method	Returns	Description
`markGeocode(<GeocodingResult> result)`	`this`	Marks a geocoding result on the map

L.Control.Geocoder.Nominatim

Uses Nominatim to respond to geocoding queries. This is the default geocoding service used by the control, unless otherwise specified in the options. Implements IGeocoder.

Unless using your own Nominatim installation, please refer to the Nominatim usage policy.

Constructor

new L.Control.Geocoder.Nominatim(options)
// or
L.Control.Geocoder.nominatim(options)

Options

Option	Type	Default	Description
`serviceUrl`	String	`"https://nominatim.openstreetmap.org/"`	URL of the service
`geocodingQueryParams`	Object	`{}`	Additional URL parameters (strings) that will be added to geocoding requests; can be used to restrict results to a specific country for example, by providing the `countrycodes` parameter to Nominatim
`reverseQueryParams`	Object	`{}`	Additional URL parameters (strings) that will be added to reverse geocoding requests
`htmlTemplate`	function	special	A function that takes an GeocodingResult as argument and returns an HTML formatted string that represents the result. Default function breaks up address in parts from most to least specific, in attempt to increase readability compared to Nominatim's naming

L.Control.Geocoder.Bing

Uses Bing Locations API to respond to geocoding queries. Implements IGeocoder.

Note that you need an API key to use this service.

Constructor

new L.Control.Geocoder.Bing(<String> key)
// or
L.Control.Geocoder.bing(<String> key)

IGeocoder

An interface implemented to respond to geocoding queries.

Methods

Method	Returns	Description
`geocode(<String> query, callback, context)`	`GeocodingResult[]`	Performs a geocoding query and returns the results to the callback in the provided context
`reverse(<L.LatLng> location, <Number> scale, callback, context)`	`GeocodingResult[]`	Performs a reverse geocoding query and returns the results to the callback in the provided context

GeocodingResult

An object that represents a result from a geocoding query.

Properties

Property	Type	Description
`name`	String	Name of found location
`bbox`	L.LatLngBounds	The bounds of the location
`center`	L.LatLng	The center coordinate of the location
`icon`	String	URL for icon representing result; optional
`html`	String	(optional) HTML formatted representation of the name
