react-leaflet-search

A React component for searching places or global coordinates on leaflet

Both react-leaflet v1 and v2 are supported.

With v1 you should import this component from "react-leaflet-search/lib/Search-v1";

import Search from "react-leaflet-search/lib/Search-v1";

default import is v2 supported (it uses withLeaflet wrapper internally)

import Search from "react-leaflet-search";

Install

npm install react-leaflet-search

css files can be found in "react-leaflet-search/css", there is no need to import when using this package as a module.

Usage

import Search from "react-leaflet-search";

import ReactLeafletSearch from "react-leaflet-search";

(default import so you can name it what ever you want.)

This component should be a child to react-leaflet's map component:

const searchComponent = (props) => <ReactLeafletSearch position="topleft" />;

Search providers

There are 2 search providers, but with scope for adding more. The default provider is OpenStreetMap. If you want to use BingMap as a provider, it can be done as follows:

const searchComponent = props => (
  <ReactLeafletSearch
            position="topleft"
            provider="BingMap"
            providerOptions={{providerKey:"{BINGMAP_KEY}"}} />
)

You can pass in provider-specific options using the providerOptions prop:

const searchComponent = (props) => <ReactLeafletSearch position="topleft" provider="OpenStreetMap" providerOptions={{ region: "gb" }} />;

to create a custom provider just create an Object

const customProvider = {
  search: async (inputValue: string) => {
    // do fetch or anything
    return {
      info: Array<{
                      bounds: boundingBox,
                      latitude: number,
                      longitude: number,
                      name: displayName
                  }> | string,
      raw: rawResponse
    }
  }
}

const component = <ReactLeafletSearch customProvider={customProvider} />

Search Result Marker

To change the marker icon, use the markerIcon prop:

const myIcon = L.icon({
    iconUrl: "marker-icon.png",
    iconRetinaUrl: "marker-icon-2x.png",
    shadowUrl: "marker-shadow.png",
    iconSize: [25, 41],
    iconAnchor: [12, 41],
    popupAnchor: [1, -34],
    tooltipAnchor: [16, -28],
    shadowSize: [41, 41]
});

<ReactLeafletSearch position="topleft" markerIcon={myIcon} />;

To change the Popup displayed by the marker, use the popUp prop:

myPopup(SearchInfo) {
  return(
    <Popup>
      <div>
        <p>I am a custom popUp</p>
        <p>latitude and longitude from search component: lat:{SearchInfo.latLng[0]} lng:{SearchInfo.latLng[1]}</p>
        <p>Info from search component: {SearchInfo.info}</p>
        <p>{JSON.stringify(SearchInfo.raw)}</p>
      </div>
    </Popup>
  );
}

<ReactLeafletSearch position="topleft" popUp={ myPopup }/>

Other props which can be set on the `ReactLeafletSearch` component

Other aspects can be customized as well:

<ReactLeafletSearch
    position="topleft"
    inputPlaceholder="The default text in the search bar"
    search={[]} // Setting this to [lat, lng] gives initial search input to the component and map flies to that coordinates, its like search from props not from user
    zoom={7} // Default value is 10
    showMarker={true}
    showPopup={false}
    openSearchOnLoad={false} // By default there's a search icon which opens the input when clicked. Setting this to true opens the search by default.
    closeResultsOnClick={false} // By default, the search results remain when you click on one, and the map flies to the location of the result. But you might want to save space on your map by closing the results when one is clicked. The results are shown again (without another search) when focus is returned to the search input.
    providerOptions={{searchBounds: []}} // The BingMap and OpenStreetMap providers both accept bounding coordinates in [se,nw] format. Note that in the case of OpenStreetMap, this only weights the results and doesn't exclude things out of bounds.
    customProvider={undefined | {search: (searchString)=> {}}} // see examples to usage details until docs are ready
/>

Styling Component

you can add custom style

<ReactLeafletSearch className="custom-style">

.custom-style {
  box-shadow: 0 1px 5px rgba(0,0,0,0.65);
  --icon-width: 26px;
  --icon-height: 26px;
  --active-height: 40px;
  --close-button-max-size: 12px;
  --icon-button-max-size: 18px;

  --background-color-candidate: #5a6673;
  --background-color-hover: #5a6673b3;
  --background-color-active: #50c3bd;
  --svg-stroke-width: 5px;
}

Info about search input

It has two modes:

Search for latitude,longitude as numbers
Search for a place with its name, city, country, street etc.

To search with global coordinates, the search input should start with the ':' character and should respect the following format: :{LATITUDE},{LONGITUDE}
