React Places Autocomplete

A React component to build a customized UI for Google Maps Places Autocomplete

Demo

Live demo: hibiken.github.io/react-places-autocomplete/

Features

1. Enable you to easily build a customized autocomplete dropdown powered by Google Maps Places Library
2. Utility functions to geocode and get latitude and longitude using Google Maps Geocoder API
3. Full control over rendering to integrate well with other libraries (e.g. Redux-Form)
4. Mobile friendly UX
5. WAI-ARIA compliant
6. Support Asynchronous Google script loading

Installation

To install the stable version

npm install --save react-places-autocomplete

React component is exported as a default export

import PlacesAutocomplete from 'react-places-autocomplete';

utility functions are named exports

import {
  geocodeByAddress,
  geocodeByPlaceId,
  getLatLng,
} from 'react-places-autocomplete';

Getting Started

To use this component, you are going to need to load Google Maps JavaScript API

Load the library in your project

Create your component

import React from 'react';
import PlacesAutocomplete, {
  geocodeByAddress,
  getLatLng,
} from 'react-places-autocomplete';

class LocationSearchInput extends React.Component {
  constructor(props) {
    super(props);
    this.state = { address: '' };
  }

  handleChange = address => {
    this.setState({ address });
  };

  handleSelect = address => {
    geocodeByAddress(address)
      .then(results => getLatLng(results[0]))
      .then(latLng => console.log('Success', latLng))
      .catch(error => console.error('Error', error));
  };

  render() {
    return (
      
        {({ getInputProps, suggestions, getSuggestionItemProps, loading }) => (
          <div>
            <input>
            <div>
              {loading &amp;&amp; <div>Loading...</div>}
              {suggestions.map(suggestion =&gt; {
                const className = suggestion.active
                  ? 'suggestion-item--active'
                  : 'suggestion-item';
                // inline style for demonstration purpose
                const style = suggestion.active
                  ? { backgroundColor: '#fafafa', cursor: 'pointer' }
                  : { backgroundColor: '#ffffff', cursor: 'pointer' };
                return (
                  <div>
                    <span>{suggestion.description}</span>
                  </div>
                );
              })}
            </div>
          </div>
        )}
      
    );
  }
}

Props

PlacesAutocomplete is a Controlled Component with a Render Prop. Therefore, you MUST pass at least value and onChange callback to the input element, and render function via children.

Prop	Type	Required	Description
value	string	✅	value for the input element
onChange	function	✅	onChange function for the input element
children	function	✅	Render function to specify the rendering
onSelect	function		Event handler to handle user's select event
onError	function		Error handler function that gets called when Google Maps API responds with an error
searchOptions	object		Options to Google Maps API (i.e. bounds, radius)
debounce	number		Number of milliseconds to delay before making a call to Google Maps API
highlightFirstSuggestion	boolean		If set to true, first list item in the dropdown will be automatically highlighted
shouldFetchSuggestions	boolean		Component will hit Google Maps API only if this flag is set true
googleCallbackName	string		You can provide a callback name to initialize PlacesAutocomplete after google script is loaded

value

Type: string, Required: true

onChange

Type: function, Required: true

Typically this event handler will update value state.

 this.setState({ value })}
>
  {/* custom render function */}

children

Type: function Required: true

This is where you render whatever you want to based on the state of PlacesAutocomplete. The function will take an object with the following keys.

• getInputProps : function
• getSuggestionItemProps : function
• loading : boolean
• suggestions : array

Simple example

const renderFunc = ({ getInputProps, getSuggestionItemProps, suggestions }) => (
  <div>
    <input>
    <div>
      {loading &amp;&amp; <div>Loading...</div>}
      {suggestions.map(suggestion =&gt; (
        <div>
          <span>{suggestion.description}</span>
        </div>
      ))}
    </div>
  </div>
);

// In render function

  {renderFunc}
;

getInputProps

This function will return the props that you can spread over the <input> element. You can optionally call the function with an object to pass other props to the input.

// In render function
<input>

getSuggestionItemProps

This function will return the props that you can spread over each suggestion item in your autocomplete dropdown. You MUST call it with suggestion object as an argument, and optionally pass an object to pass other props to the element.

// Simple example
<div>
  {suggestions.map(suggestion =&gt; (
    <div>
      {suggestion.description}
    </div>
  ))}
</div>

// Pass options as a second argument
<div>
  {suggestions.map(suggestion =&gt; {
    const className = suggestion.active ? 'suggestion-item--active' : 'suggestion-item';
    return (
      <div>
        {suggestion.description}
      </div>
    );
  })}
</div>

loading

This is a boolean flag indicating whether or not the request is pending, or has completed.

suggestions

This is an array of suggestion objects each containing all the data from Google Maps API and other metadata.

An example of a suggestion object.

{
  active: false,
  description: "San Francisco, CA, USA",
  formattedSuggestion: { mainText: "San Francisco", secondaryText: "CA, USA" },
  id: "1b9ea3c094d3ac23c9a3afa8cd4d8a41f05de50a",
  index: 0,
  matchedSubstrings: [ {length: 8, offset: 0} ],
  placeId: "ChIJIQBpAG2ahYAR_6128GcTUEo",
  terms: [
    { offset: 0, value: "San Francisco" },
    { offset: 15, value: "CA" },
    { offset: 19, value: "USA" }
  ],
  types: ["locality", "political", "geocode"]
}

onSelect

Type: function Required: false, Default: null

You can pass a function that gets called instead of onChange function when user hits the Enter key or clicks on a suggestion item.

The function takes three positional arguments. First argument is address, second is placeId and third is the entire suggestion object.

// NOTE: `placeId` and `suggestion` are null when user hits Enter key with no suggestion item selected.
const handleSelect = (address: string, placeId: ?string, suggestion: ?object) => {
  // Do something with address and placeId and suggestion
}

// Pass this function via onSelect prop.

  {/* Custom render function */}

onError

Type: function Required: false

You can pass onError prop to customize the behavior when google.maps.places.PlacesServiceStatus is not OK (e.g., no predictions are found)

Function takes status (string) and clearSuggestions (function) as parameters

// Log error status and clear dropdown when Google Maps API returns an error.
const onError = (status, clearSuggestions) => {
  console.log('Google Maps API returned error with status: ', status)
  clearSuggestions()
}


  {/* Custom render function */}

searchOptions

Type: Object Required: false Default: {}

You can fine-tune the settings passed to the AutocompleteService class with searchOptions prop. This prop accepts an object following the same format as google.maps.places.AutocompletionRequest (except for input, which comes from the value of the input field).

// these options will bias the autocomplete predictions toward Sydney, Australia with a radius of 2000 meters,
// and limit the results to addresses only
const searchOptions = {
  location: new google.maps.LatLng(-34, 151),
  radius: 2000,
  types: ['address']
}


  {/* Custom render function */}

debounce

Type: number Required: false Default: 200

The number of milliseconds to delay before making a call to Google Maps API.

highlightFirstSuggestion

Type: boolean Required: false Default: false

If set to true, first suggestion in the dropdown will be automatically set to be active.

shouldFetchSuggestions

Type: boolean Required: false Default: true

// Only fetch suggestions when the input text is longer than 3 characters.
 3}
>
  {/* custom render function */}

googleCallbackName

Type: string Required: false Default: undefined

If provided, component will initialize after the browser has finished downloading google script.

IMPORTANT: To enable this async mode, you need to provide the same callback name to google script via callback=[YOUR CALLBACK NAME].

Example:

Then, provide googleCallbackName prop to PlacesAutocomplete.

  {/* custom render function */}

NOTE: If there are more than one PlacesAutocomplete components rendered in the page, set up a callback function that calls a callback function for each component.

Example:

  {/* custom render function */}
