Leaflet 1.0.0 ready

Leaflet + LocationIQ Autocomplete geocoding plugin

A plugin that adds the ability to search (geocode) a Leaflet-powered map using LocationIQ.


See it in action!


Requires the Leaflet mapping library. Supports Leaflet v0.7.3 (and higher) and v1.0.0. (Previous Leaflet versions may work, but are not actively tested or supported.)

Browser support is IE8+ (more details below).

To use the LocationIQ service, you need a LocationIQ API key. Get one from here. It's free!

Basic usage

Step 1: In HTML, import the required Leaflet JavaScript and CSS files. Start quickly with hosted libraries!

<!-- Load Leaflet from CDN -->
<link rel="stylesheet" href="">
<script src=""></script>

<!-- Load geocoding plugin after Leaflet -->
<link rel="stylesheet" href="">
<script src=""></script>

<!-- For the invisible map -->
<div id="map"></div>
<!-- For the search box -->
<div id="search-box"></div>
<!-- To display the result -->
<div id="result"></div>

Step 2: In JavaScript, initialize your Leaflet map.

// This is an example of Leaflet usage; you should modify this for your needs.
var map ='map').setView([40.7259, -73.9805], 12);

Step 3: In JavaScript, add your geocoder with your LocationIQ API key.


Step 4: Rejoice!

Advanced usage: Autocomplete without a map


See it in action!

Step 1: In HTML, import the required Leaflet JavaScript and CSS files. Start quickly with hosted libraries!

<!-- Load Leaflet from CDN -->
<link rel="stylesheet" href="">
<script src=""></script>

<!-- Load geocoding plugin after Leaflet -->
<link rel="stylesheet" href="">
<script src=""></script>

<!-- For the invisible map -->
<div id="map"></div>
<!-- For the search box -->
<div id="search-box"></div>
<!-- To display the result -->
<div id="result"></div>

Step 2: In JavaScript, initialize your Leaflet map.

// Initialize an empty map without layers (invisible map)
var map ='map', {
    center: [40.7259, -73.9805], // Map loads with this location as center
    zoom: 12,
    scrollWheelZoom: true,
    zoomControl: false,
    attributionControl: false,

Step 3: In JavaScript, add your geocoder including the options with your LocationIQ API key.

//Geocoder options
var geocoderControlOptions = {
    bounds: false,          //To not send viewbox
    markers: false,         //To not add markers when we geocoder
    attribution: null,      //No need of attribution since we are not using maps
    expanded: true,         //The geocoder search box will be initialized in expanded mode
    panToPoint: false       //Since no maps, no need to pan the map to the geocoded-selected location

//Initialize the geocoder
var geocoderControl = new L.control.geocoder('<your-api-key>', geocoderControlOptions).addTo(map).on('select', function (e) {
    displayLatLon(e.feature.feature.display_name,, e.latlng.lng);

Step 4: Add the following CSS

<style type="text/css">
  body {
      margin: 0;
  #map {
      width: 0;
      height: 0;
      display: none;
  #search-box {
      padding-left: 20px;
      padding-top: 20px;
      width: 800px;
      height: 100px;
  #result {
      padding-left: 20px;
      padding-top: 20px;
      width: 800px;
      height: 100px;
      padding-top: 45px;

Customizing the plugin

You can optionally specify additional settings to the plugin by passing in an object as a second argument to the geocoder() method, like so:

var options = {
  bounds: true,
  position: 'topright',
  expanded: true

L.control.geocoder('<your-api-key>', options).addTo(map);

Here are a list all the settings and their default values.

Query behavior

Some options affect the LocationIQ query itself.

option description default value
url String. Host API endpoint for LocationIQ. ''
focus Leaflet LatLng object or Boolean. If true, search and autocomplete prioritizes results near the center of the current view. You may also provide a custom LatLng value (in any of the accepted Leaflet formats) to act as the center bias. true
params Object. An object of key-value pairs which will be serialized into query parameters that will be passed to the API. This allows custom queries that are not already supported by the convenience options listed above. For a full list of supported parameters, please read the LocationIQ Autocomplete API documentation. In the event that other options conflict with parameters passed passed through params, the params option takes precedence. null


// Searching nearby [50.5, 30.5]
L.control.geocoder('<your-api-key>', {
  focus: [50.5, 30.5], // this can also written as {lat: 50.5, lon: 30.5} or L.latLng(50.5, 30.5)
  placeholder: 'Search nearby [50.5, 30.5]'

// Taking just the center of the map (lat/lon) into account
L.control.geocoder('<your-api-key>', {
  focus: true,
  placeholder: 'Search nearby'

// Custom filtering parameters
// For a full list of params, read the [documentation](
L.control.geocoder('<your-api-key>', {
  params: {
    bounded: 1,
    countrycodes: 'IN,US'
  placeholder: 'Results via Who’s on First in Australia'

Interaction behavior

These options affect the plugin's appearance and interaction behavior.

option description default value
position String. Corner in which to place the geocoder control. Values correspond to Leaflet control positions. 'topleft'
attribution String. Attribution text that will be appended to Leaflet’s attribution control. Set to a blank string or null to disable adding the plugin’s default attribution. 'Geocoding by <a href="">LocationIQ</a>'
textStrings Object. An object of string values that replace text strings in the geocoder control, so you can provide your own custom messages or localization. See “Custom text strings” section below.
placeholder String. Placeholder text to display in the search input box. This is an alias for textStrings.INPUT_PLACEHOLDER. Set to a blank string or null to disable. 'Search'
title Deprecated. Please use `textStrings.INPUT_TITLE_ATTRIBUTE instead.
panToPoint Boolean. If true, highlighting a search result pans the map to that location. true
markers Leaflet Marker options object or Boolean. If true, search results drops Leaflet's default blue markers onto the map. You may customize this marker's appearance and behavior using Leaflet marker options. true
overrideBbox Boolean. Some search results will zoom to a bounding box if it is available, instead of dropping a point marker. If true, selecting a result will always drop a point marker regardless of whether bounding box data is present. false
fullWidth Integer or Boolean. If true, the input box will expand to take up the full width of the map container. If an integer breakpoint is provided, the full width applies only if the map container width is below this breakpoint. 650
expanded Boolean. If true, the search input is always expanded. It does not collapse into a button-only state. false
autocomplete Boolean. If true, suggested results are fetched on each keystroke. If false, this is disabled and users must obtain results by pressing the Enter key after typing in their query. true


// Different position
L.control.geocoder('<your-api-key>', {
  position: 'topright'

// Disable zoom/pan to a point while browsing the results (up/down arrows)
L.control.geocoder('<your-api-key>', {
  panToPoint: false

// Set the geocoder to always be the full width of the map
// By default, the geocoder is only full width when the screen is less than 650 pixels wide
L.control.geocoder('<your-api-key>', {
  fullWidth: true

// Disable markers for search results
L.control.geocoder('<your-api-key>', {
  markers: false

// Force the geocoder to always be in the expanded state
L.control.geocoder('<your-api-key>', {
  expanded: true

// Changing attribution
// By default, adds "Geocoding by LocationIQ" text with a link
// You can remove this if you like, or change the text.
L.control.geocoder('<your-api-key>', {
  attribution: null

Custom text strings

These are the text strings that are used by the geocoder control. You can override these strings by passing in a textStrings options object containing the names of the string(s) you want to customize. You can use this method to localize the controls for a different language, for instance.

UI text

string name default value
NO_RESULTS 'No results were found.'

HTTP status code errors

Learn more about possible error messages in LocationIQ documentation. ERROR_DEFAULT is a catch-all error that displays when a request returns an error with an unexpected HTTP status code (or none at all) — one example where this can happen is when a browser is prevented from making a request due to a security concern, such as the lack of CORS headers on the search endpoint.

string name default value
ERROR_403 'A valid API key is needed for this search feature.'
ERROR_404 'The search service cannot be found. :-('
ERROR_408 'The search service took too long to respond. Try again in a second.'
ERROR_429 'There were too many requests. Try again in a second.'
ERROR_500 'The search service is not working right now. Please try again later.'
ERROR_502 'Connection lost. Please try again later.'
ERROR_DEFAULT 'The search service is having problems :-('


// Uses custom text strings to localise the geocoder control.
L.control.geocoder('<your-api-key>', {
  textStrings: {
    INPUT_PLACEHOLDER: '도시, 지명 등을 검색해보세요.',
    INPUT_TITLE_ATTRIBUTE: '도시, 지명 등을 검색해보세요.',
    NO_RESULTS: '해당 결과가 없습니다.',
    ERROR_403: '해당 서비스를 사용하기 위해서는 API KEY가 필요합니다.',
    ERROR_404: '검색 서비스를 찾을 수 없습니다. :-(',
    ERROR_408: '검색에 예상보다 긴 시간이 소요되고 있습니다. 조금 있다가 다시 시도해보는 건 어떨까요?',
    ERROR_429: '지나치게 많은 리퀘스트가 발생했습니다. 조금 있다가 다시 시도해보는 건 어떨까요?',
    ERROR_500: '검색 서비스가 현재 작동하지 않고있습니다. 조금 있다가 다시 시도해보는 건 어떨까요?',
    ERROR_502: '네트워크 상태가 불안정합니다. 조금 있다가 다시 시도해보는 건 어떨까요?',
    ERROR_DEFAULT: '검색 서비스에 문제가 있는 것으로 보입니다. :-('

Alternate syntax

You can instantiate a geocoder with the new keyword. Notice that the class names are capitalized. This is what actually happens under the hood of L.control.geocoder(), so this syntax does not do anything different, but you may prefer it for clarity or stylistic reasons.

new L.Control.Geocoder('<your-api-key>').addTo(map);

Scripting with the plugin

When instantiating a geocoder, you may assign it to a variable. This will allow you to use its methods later on.

var geocoder = L.control.geocoder('<your-api-key>');

// or with `new` keyword
var geocoder = new L.Control.Geocoder('<your-api-key>');

// later

The plugin extends Leaflet's Control class, so you may use any of those methods to modify plugin behavior in your script.

// examples
var element = geocoder.getContainer();
geocoder.removeFrom(map); // or geocoder.remove() in Leaflet v1


You can retrieve the current version of the geocoder.



There are additional methods on the geocoder that you can use.

// Expand the geocoder.
// Fires the `expand` event.

// Collapse the geocoder.
// This works even if the option `expanded` is set to true!
// Fires the `collapse` event.

// Focus on the geocoder input.
// This will also expand the geocoder if it's collapsed.

// Removes focus from the geocoder input.
// This also clears results and collapses the geocoder (if enabled).

// Clears inputs and results from the geocoder control.
// This does not affect collapse or expanded state, and does not remove focus.
// Fires the `reset` event.


The geocoder includes all of Leaflet's events methods and adds additional events that you can subscribe to, so that you can customize what happens when users interact with the geocoder. When you instantiate a new geocoder, assign it to variable, as above, and then you can use the event methods to listen for the events that it's firing. For example:

geocoder.on('select', function (e) {
  console.log('You’ve selected',;

All of Leaflet's event methods are available, such as on, off, once, and so on. The exact syntax and how it behaves are inherited from the version of Leaflet you are plugging into, so there are slight differences between the 0.7.x version line and the 1.0.0 version line.

The following events are fired:

event description
results Fired when search results are obtained.
error Fired if there was an error with a search request.
select Fired when a result is actively selected from the results list (not just highlighted.)
highlight Fired when a result is highlighted by the up/down arrow keys.
expand Fired when the geocoder is expanded.
collapse Fired when the geocoder is collapsed.
reset Fired when the geocoder is reset ("x" button is clicked).
focus Fired when the geocoder is focused on the input.
blur Fired when the geocoder loses focus on the input.

Getting data

Certain events will pass data as the first argument to the event listener's callback function.

on results or error

In addition to the base event object from Leaflet, the event object will contain these other useful properties:

property description
endpoint A string of the LocationIQ API endpoint that was called.
requestType A string, either autocomplete, search, or place, depending on the request made.
params An object containing the parameters that have been passed to the LocationIQ request.
results The original response object returned from LocationIQ, including all feature geometries and properties.

If there was an error with the request, the event object will contain the additional properties:

property description
errorCode The HTTP status code received. More information.
errorMessage The error message string that the geocoder will display.

on select and highlight

property description
originalEvent The original event object (MouseEvent or KeyboardEvent) reported by the browser.
latlng A Leaflet LatLng object representing the coordinates of the result.
feature The JSON object returned by LocationIQ

on focus and blur

property description
originalEvent The original FocusEvent event object reported by the browser.

Browser support

This plugin supports all Leaflet-supported browsers except for Internet Explorer 7. It makes a cross-domain request in Javascript to obtain search results, which is not supported in IE7 without JSONP.
