⚠️ Maintainers Wanted Maintainers Wanted

We are in need of more people or companies willing to help. If you have enough time and knowledge, and want to become a maintainer, please open a new issue.

Preview

Installation

Step 1.

npm install react-native-google-places-autocomplete --save

or

yarn add react-native-google-places-autocomplete

Step 2.

Get your Google Places API keys and enable "Google Places API Web Service" (NOT Android or iOS) in the console. Billing must be enabled on the account.

Step 3.

Enable "Google Maps Geocoding API" if you want to use GoogleReverseGeocoding for Current Location

Basic Example

Basic Address Search

import React from 'react';
import { GooglePlacesAutocomplete } from 'react-native-google-places-autocomplete';

const GooglePlacesInput = () => {
  return (
    <GooglePlacesAutocomplete
      placeholder='Search'
      onPress={(data, details = null) => {
        // 'details' is provided when fetchDetails = true
        console.log(data, details);
      }}
      query={{
        key: 'YOUR API KEY',
        language: 'en',
      }}
    />
  );
};

export default GooglePlacesInput;

More Examples

Get Current Location

Click to expand

Extra step required!

If you are targeting React Native 0.60.0+ you must install either @react-native-community/geolocation (link) or react-native-geolocation-service(link).

Please make sure you follow the installation instructions there and add navigator.geolocation = require(GEOLOCATION_PACKAGE) somewhere in you application before <GooglePlacesAutocomplete />.

import React from 'react';
import { GooglePlacesAutocomplete } from 'react-native-google-places-autocomplete';

// navigator.geolocation = require('@react-native-community/geolocation');
// navigator.geolocation = require('react-native-geolocation-service');

const GooglePlacesInput = () => {
  return (
    <GooglePlacesAutocomplete
      placeholder='Search'
      onPress={(data, details = null) => {
        // 'details' is provided when fetchDetails = true
        console.log(data, details);
      }}
      query={{
        key: 'YOUR API KEY',
        language: 'en',
      }}
      currentLocation={true}
      currentLocationLabel='Current location'
    />
  );
};

export default GooglePlacesInput;

Search with predefined option

Click to expand 
import React from 'react';
import { GooglePlacesAutocomplete } from 'react-native-google-places-autocomplete';

const homePlace = {
  description: 'Home',
  geometry: { location: { lat: 48.8152937, lng: 2.4597668 } },
};
const workPlace = {
  description: 'Work',
  geometry: { location: { lat: 48.8496818, lng: 2.2940881 } },
};

const GooglePlacesInput = () => {
  return (
    <GooglePlacesAutocomplete
      placeholder='Search'
      onPress={(data, details = null) => {
        // 'details' is provided when fetchDetails = true
        console.log(data, details);
      }}
      query={{
        key: 'YOUR API KEY',
        language: 'en',
      }}
      predefinedPlaces={[homePlace, workPlace]}
    />
  );
};

export default GooglePlacesInput;

Limit results to one country

Click to expand 
import React from 'react';
import { GooglePlacesAutocomplete } from 'react-native-google-places-autocomplete';

const GooglePlacesInput = () => {
  return (
    <GooglePlacesAutocomplete
      placeholder='Search'
      onPress={(data, details = null) => {
        // 'details' is provided when fetchDetails = true
        console.log(data, details);
      }}
      query={{
        key: 'YOUR API KEY',
        language: 'en',
        components: 'country:us',
      }}
    />
  );
};

export default GooglePlacesInput;

Use a custom Text Input Component

Click to expand

This is an example using the Text Input from react-native-elements.

import React from 'react';
import { Text, View, Image } from 'react-native';
import { GooglePlacesAutocomplete } from 'react-native-google-places-autocomplete';
import { Input } from 'react-native-elements';

const GOOGLE_PLACES_API_KEY = 'YOUR_GOOGLE_API_KEY';

const GooglePlacesInput = () => {
  return (
    <GooglePlacesAutocomplete
      query={{
        key: GOOGLE_PLACES_API_KEY,
        language: 'en', // language of the results
      }}
      onPress={(data, details) => console.log(data, details)}
      textInputProps={{
        InputComp: Input,
        leftIcon: { type: 'font-awesome', name: 'chevron-left' },
        errorStyle: { color: 'red' },
      }}
    />
  );
};

export default GooglePlacesInput;

Methods

method name type description
getAddressText () => string return the value of TextInput
setAddressText (value: string) => void set the value of TextInput
focus void makes the TextInput focus
blur void makes the TextInput lose focus
clear void removes all text from the TextInput

getCurrentLocation () => void makes a query to find nearby places based on current location

You can access these methods using a ref.

Example

import React, { useEffect, useRef } from 'react';
import { GooglePlacesAutocomplete } from 'react-native-google-places-autocomplete';

const GooglePlacesInput = () => {
  const ref = useRef();

  useEffect(() => {
    ref.current?.setAddressText('Some Text');
  }, []);

  return (
    <GooglePlacesAutocomplete
      ref={ref}
      placeholder='Search'
      onPress={(data, details = null) => {
        // 'details' is provided when fetchDetails = true
        console.log(data, details);
      }}
      query={{
        key: 'YOUR API KEY',
        language: 'en',
      }}
    />
  );
};

export default GooglePlacesInput;

Web Support

Web support can be enabled via the requestUrl prop, by passing in a URL that you can use to proxy your requests. CORS implemented by the Google Places API prevent using this library directly on the web. You will need to use a proxy server. Please be mindful of this limitation when opening an issue.

The requestUrl prop takes an object with two required properties: useOnPlatform and url, and an optional headers property.

The url property is used to set the url that requests will be made to. If you are using the regular google maps API, you need to make sure you are ultimately hitting https://maps.googleapis.com/maps/api.

useOnPlatform configures when the proxy url is used. It can be set to either web- will be used only when the device platform is detected as web (but not iOS or Android, or all - will always be used.

You can optionally specify headers to apply to your request in the headers object.

Example:

import React from 'react';
import { GooglePlacesAutocomplete } from 'react-native-google-places-autocomplete';

const GooglePlacesInput = () => {
  return (
    <GooglePlacesAutocomplete
      placeholder='Search'
      onPress={(data, details = null) => {
        // 'details' is provided when fetchDetails = true
        console.log(data, details);
      }}
      query={{
        key: 'YOUR API KEY',
        language: 'en',
      }}
      requestUrl={{
        useOnPlatform: 'web', // or "all"
        url:
          'https://cors-anywhere.herokuapp.com/https://maps.googleapis.com/maps/api', // or any proxy server that hits https://maps.googleapis.com/maps/api
        headers: {
          Authorization: `an auth token`, // if required for your proxy
        },
      }}
    />
  );
};

export default GooglePlacesInput;

Note: The library expects the same response that the Google Maps API would return.

Features

  • Places autocompletion
  • iOS and Android compatibility
  • Places details fetching + ActivityIndicatorIOS/ProgressBarAndroid loaders
  • Customizable using the styles parameter
  • XHR cancellations when typing fast
  • Google Places terms compliant
  • Predefined places
  • typescript types
  • Current location

Compatibility

This library does not use the iOS, Android or JS SDKs from Google. This comes with some Pros and Cons.

Pros:

  • smaller app size
  • better privacy for your users (although Google still tracks server calls)
  • no need to keep up with sdk updates

Cons:

  • the library is not compatible with a Application key restrictions
  • doesn't work directly on the web without a proxy server
  • any Google API change can be a breaking change for the library.
