A React autosuggest for the Google Maps Places API.

Primary LanguageJavaScript

React Geosuggest Build Status

A React autosuggest for the Google Maps Places API. You can also define your own suggests as defaults. Works with Preact, too.

Demo

Live demo: ubilabs.github.io/react-geosuggest

Installation

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 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

Usage

The Geosuggest works out of the box by just including it. However, you can customize the behaviour with the properties noted below.

var Geosuggest = require('react-geosuggest');

<Geosuggest />

location

Restricts predictions to the specified country (ISO 3166-1 Alpha-2 country code, case insensitive). E.g., us, br, au.

types

Type: Array Default: null

Restricts the suggestions against the passed in types. If none are specified, all types are used. Consult the Google Docs for possible types.

fixtures

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.

googleMaps

Type: Object Default: google.maps

onFocus

Type: Function Default: function() {}

Gets triggered when the input field receives focus.

onBlur

Type: Function Default: function() {}

Gets triggered when input field loses focus.

onChange

Type: Function Default: function(value) {}

Gets triggered when input field changes the value

onSuggestSelect

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 – Type String – The label name
  • placeId – Type String – If it is a preset, equals the label. Else it is the Google Maps placeID
  • location – Type Object – The location containing lat and lng
  • gmaps – Type Object – 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.

onActivateSuggest

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 – Type String – The label name
  • placeId – Type String – If it is a preset, equals the label. Else it is the Google Maps placeID

getSuggestLabel

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.

skipSuggest

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)

autoActivateFirstSuggest

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.

Others

All standard input[type="text"] attributes are allowed. See the documentation for more information.

Exposed component functions

focus()

Call focus to focus on the element. The suggest list will be expanded with the current suggestions.

update(value)

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.

clear()

It is also possible to clear the value of the input contained within the GeoSuggest component by calling the clear function.

Example

var React = require('react'),
  Geosuggest = require('./src/Geosuggest.jsx');

var App = React.createClass({
  /**
   * Render the example app
   */
  render: function() {
    var fixtures = [
      {label: 'Old Elbe Tunnel, Hamburg', location: {lat: 53.5459, lng: 9.966576}},
      {label: 'Reeperbahn, Hamburg', location: {lat: 53.5495629, lng: 9.9625838}},
      {label: 'Alster, Hamburg', location: {lat: 53.5610398, lng: 10.0259135}}
    ];

    return (
      <div>
        <Geosuggest
          placeholder="Start typing!"
          initialValue="Hamburg"
          fixtures={fixtures}
          onSuggestSelect={this.onSuggestSelect}
          location={new google.maps.LatLng(53.558572, 9.9278215)}
          radius="20" />
      </div>
    )
  },

  /**
   * When a suggest got selected
   * @param  {Object} suggest The suggest
   */
  onSuggestSelect: function(suggest) {
    console.log(suggest);
  }
});

React.render(<App />, document.getElementById('app'));

Styling

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.
