A React autosuggest for the Google Maps Places API. You can also define your own suggests as defaults. Works with Preact, too.
Live demo: ubilabs.github.io/react-geosuggest
As this component uses the Google Maps Places API to get suggests, you must include the Google Maps Places API in the <head>
of your HTML:
<!DOCTYPE html>
<html>
<head>
…
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY_HERE&libraries=places"></script>
</head>
<body>
…
</body>
</html>
Visit the Google Developer Console to generate your API key. The API's that you have to enable in your Google API Manager Dashboard are Google Maps Geocoding API, Google Places API Web Service and [Google Maps Javascript API] (https://developers.google.com/maps/documentation/javascript/).
The easiest way to use geosuggest is to install it from NPM and include it in your own React build process (using Browserify, Webpack, etc).
You can also use the standalone build by including dist/react-geosuggest.js
in your page. If you use this, make sure you have already included React, and it is available as a global variable.
npm install react-geosuggest --save
The Geosuggest works out of the box by just including it. However, you can customize the behaviour with the properties noted below.
import Geosuggest from 'react-geosuggest';
<Geosuggest />
var Geosuggest = require('react-geosuggest').default;
<Geosuggest />
Type: String
Default: Search places
The input field will get this placeholder text.
Type: String
Default: ''
An initial value for the input, when you want to prefill the suggest.
Type: String
Default: ''
Add an additional class to the geosuggest container.
Type: Object
Default: { 'input': {}, 'suggests': {}, 'suggestItem': {} }
Add an additional style to Geosuggest
.
This would support overriding/adding styles to the input suggestList and suggestItem.
Type: String
Default: ''
Add an additional class to the input.
Type: Boolean
Default: false
Defines whether the input is disabled.
Type: google.maps.LatLng
Default: null
To get localized suggestions, define a location to bias the suggests.
Type: Number
Default: 0
The radius defines the area around the location to use for biasing the suggests. It must be accompanied by a location
parameter.
Type: LatLngBounds
Default: null
The bounds to use for biasing the suggests. If this is set, location
and radius
are ignored.
Type: String
Default: null
Restricts predictions to the specified country (ISO 3166-1 Alpha-2 country code, case insensitive). E.g., us, br, au.
Type: Array
Default: null
The types of predictions to be returned. Four types are supported: establishment
for businesses, geocode
for addresses, (regions)
for administrative regions and (cities)
for localities. If nothing is specified, all types are returned. Consult the Google Docs for up to date types.
Type: Array
Default: []
An array with fixtures (defaults). Each fixture has to be an object with a label
key in it. Optionally provide a location
, but the Geosuggest will geocode the label if no location is provided.
You can also add a className
key to a fixture. This class will be applied to the fixture item.
Type: Object
Default: google.maps
In case you want to provide your own Google Maps object, pass it in as googleMaps. The default is the global google maps object.
Type: Boolean
Default: false
When the tab key is pressed, the onSelect
handler is invoked. Set to true to not invoke onSelect
on tab press.
Type: Number
Default: 250
Sets the delay in milliseconds after typing before a request will be sent to find suggestions.
Specify 0
if you wish to fetch suggestions after every keystroke.
Type: Function
Default: function() {}
Gets triggered when the input field receives focus.
Type: Function
Default: function(value) {}
Gets triggered when input field loses focus.
Type: Function
Default: function(value) {}
Gets triggered when input field changes the value.
Type: Function
Default: function(event) {}
Gets triggered when input field gets key press.
Type: Function
Default: function(suggest) {}
Gets triggered when a suggest got selected. Only parameter is an object with data of the selected suggest. This data is available:
label
– TypeString
– The label nameplaceId
– TypeString
– If it is a preset, equals thelabel
. Else it is the Google MapsplaceID
location
– TypeObject
– The location containinglat
andlng
gmaps
– TypeObject
– Optional! The complete response when there was a Google Maps geocode necessary (e.g. no location provided for presets). Check the Google Maps Reference for more information on it’s structure.
Type: Function
Default: function(suggest) {}
Gets triggered when a suggest is activated in the list. Only parameter is an object with data of the selected suggest. This data is available:
label
– TypeString
– The label nameplaceId
– TypeString
– If it is a preset, equals thelabel
. Else it is the Google MapsplaceID
Type: Function
Default: function(userInput) {}
Gets triggered when there are no suggest results found
Type: Function
Default: function(suggest) { return suggest.description; }
Used to generate a custom label for a suggest. Only parameter is a suggest (google.maps.places.AutocompletePrediction). Check the Google Maps Reference for more information on it’s structure.
Type: Function
Default: function(suggest) {}
If the function returns true then the suggest will not be included in the displayed results. Only parameter is an object with data of the selected suggest. (See above)
Type: Boolean
Default: false
Automatically activate the first suggestion as you type. If false, the exact term(s) in the input will be used when searching and may return a result not in the list of suggestions.
Type: String
Default: null
If the label

element.
suggestsHiddenClassName
Type: String
Default: null
Additional className

Type: String
,
Default: null
Additional className
to add when a suggestion item is active.
All allowed attributes for input[type="text"]
All DOM clipboard events.
All DOM mouse events except for drag & drop.
These functions are accessible by setting "ref" on the component (see example below)
Call focus
to focus on the element. The suggest list will be expanded with the current suggestions.
Call blur
to blur (unfocus) the element. The suggest list will be closed.
It is possible to update the value of the input contained within the GeoSuggest component by calling the update
function with a new desired value
of the type String.
It is also possible to clear the value of the input contained within the GeoSuggest component by calling the clear
function.

This component uses BEM for namespacing the CSS classes. So styling should be easy and without conflicts. See the geosuggest.css for an example styling.
The geosuggest__suggests--hidden
class is added to hide the suggestion list. You should copy the style below into your CSS file.
.geosuggest__suggests--hidden {
max-height: 0;
overflow: hidden;
border-width: 0;
}
The above class is added whenever the suggestion list needs to be hidden. This occurs when the user selects an item from the list or when the user triggers the blur
event on the input.
Similarly, you need to have the class geosuggest__item--active
similar to this:
.geosuggest__item--active {
background: #267dc0;
color: #fff;
}
to see what item is selected, f.ex. when using the arrow keys to navigate the suggestion list.
