Stadia Maps MapLibre Search Box
This MapLibre GL JS plugin adds support for the Stadia Maps Search Autocomplete APIs to any MapLibre GL JS map.
Based on the Stadia Maps TS SDK, it automatically handles best-practice functionality for search, including debouncing of requests, caching of previous results, and zooming the map when a result is selected.
Getting Started
Adding the search box to a map is straightforward:
- Add the TS/JS and CSS dependencies.
- Instantiate the control (optionally customize the settings).
- Add the control to the map.
Create a Stadia Maps account
You can try everything out locally in a web browser without any special setup! To deploy to an internet server though, you'll need a Stadia Maps account. Learn more about how we authenticate requests in our documentation, and sign up for a free account (no credit card required) using our client dashboard.
Using build tooling
First, add @stadiamaps/maplibre-search-box
as a dependency of your project using your favorite package manager
like npm
or yarn
.
$ npm install --save @stadiamaps/maplibre-search-box
Import and use the package along with the map. (Be sure to add the control to the map!)
import { MapLibreSearchControl } from "@stadiamaps/maplibre-search-box";
import "@stadiamaps/maplibre-search-box/dist/style.css";
const control = new MapLibreSearchControl();
const map = new maplibregl.Map({
container: "map",
style: "https://tiles.stadiamaps.com/styles/alidade_smooth.json", // stylesheet location
center: [-74.5, 40], // starting position [lng, lat]
zoom: 2, // starting zoom
});
map.addControl(control, "top-left");
Using Unpkg
Add this to your <head>
:
<script
src="https://unpkg.com/browse/@stadiamaps/maplibre-search-box/dist/maplibre-search-box.umd.js"
type="application/javascript"
></script>
<link
href="https://unpkg.com/browse/@stadiamaps/maplibre-search-box/dist/style.css"
rel="stylesheet"
/>
Add this to your <body>
:
<div id="map" style="height: 100vh; width: 100vw"></div>
<script type="application/javascript">
var control = new maplibreSearchBox.MapLibreSearchControl({
useMapFocusPoint: true,
});
var map = new maplibregl.Map({
container: "map",
style: "https://tiles.stadiamaps.com/styles/alidade_smooth.json", // stylesheet location
center: [-74.5, 40], // starting position [lng, lat]
zoom: 2, // starting zoom
});
map.addControl(control, "top-left");
</script>
Options
The MapLibreSearchControl
constructor takes a set of options (as an object):
Options Overview
export class MapLibreSearchControlOptions {
useMapFocusPoint = true;
mapFocusPointMinZoom = 5;
fixedFocusPoint: [number, number] = null;
searchOnEnter = false;
maxResults = 5;
minInputLength = 3;
minWaitPeriodMs = 100;
layers: PeliasLayer[] = null;
onResultSelected?: (feature: PeliasGeoJSONFeature) => void;
baseUrl: string | null = null;
}
Options Detail
useMapFocusPoint
If set, the map center point is used to influence the search for better contextual results.
mapFocusPointMinZoom
On low zooms, the focus point is often unuseful for contextual results (e.g., on zoom 0, the whole world is visible, so the center is not valuable). This controls at what zoom the center is used to influence results.
fixedFocusPoint
A single point used to influence results (doesn't follow the map viewport).
searchOnEnter
For address-based forward geocoding applications, it often makes sense to use the forward geocoding (/search
) endpoint
rather than autocomplete search, once you know that the user has completed their input. The full forward geocoding
endpoint is able to interpolate addresses, and may provide better results with complete input than the autocomplete
endpoint. Opting in to this behavior will send a final forward geocoding request if the user presses enter.
Note: the /search
endpoint is not available to all plans, so check if your plan supports /search
before enabling
this. You can find the full feature comparison on our pricing page.
maxResults
Maximum number of results to return.
minInputLength
Minimum number of characters to wait for before making the first search.
minWaitPeriodMs
The minimum time to wait between searches. Higher values decrease the number of API requests made, but increase the received latency of the input.
layers
Which layers to use in the search. Defaults to all layers. See the Layers documentation for more details.
Note: if you want the fastest possible search, but don't mind excluding addresses or Point of Interest (venue
)
results, use ['coarse']
for the best performance.
onResultSelected
A callback to be invoked whenever a result is selected by the user. This is invoked with a single argument, the
PeliasFeature
for the result. This allows you take an action (such as autofilling your own form).
baseUrl
An optional override to the base API URL. This defaults to the primary Stadia Maps API endpoint. If you want
to use our EU endpoints to ensure traffic is handled by EU servers,
set the baseUrl
to https://api-eu.stadiamaps.com
.
