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.

$3

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

const GooglePlacesInput = () => {
return (
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

- [x] typescript types
- [x] 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.

If you need to include this component inside a ScrolView or FlatList, remember to apply the keyboardShouldPersistTaps attribute to all ancestors ScrollView or FlatList (see this issue comment).

A word about the Google Maps APIs

Google Provides a bunch of web APIs for finding an address or place, and getting it’s details.
There are the Google Places Web APIs (Place Search, Place Details, Place Photos, Place Autocomplete, Query Autocomplete) and the Google Geocode API .

The 5 Google Places Web APIs are:

- Place Autocomplete - automatically fills in the name and/or address of a place as users type.
- Place Details - returns more detailed information about a specific place (using a place_id that you get from Place Search, Place Autocomplete, or Query Autocomplete).
- Place Photos - provides access to the millions of place-related photos stored in Google's Place database (using a reference_id that you get from Place Search, Place Autocomplete, or Query Autocomplete).
- Place Search - returns a list of places based on a user's location or search string.
- Query Autocomplete - provides a query prediction service for text-based geographic searches, returning suggested queries as users type.

The Geocoding API allows you to convert an address into geographic coordinates (lat, long) and to "reverse geocode", which is the process of converting geographic coordinates into a human-readable address.

$3

Place Autocomplete API, Place Details API, Place Search API and the Geocoding API.

We use the Place Autocomplete API to get suggestions as you type. When you click on a suggestion, we use the Place Details API to get more information about the place.

We use the Geocoding API and the Place Search API to use your current location to get results.

Because the query parameters are different for each API, there are 4 different "query" props.

1. Autocomplete -> query (options)
2. Place Details -> GooglePlacesDetailsQuery (options)
3. Nearby Search -> GooglePlacesSearchQuery (options)
4. Geocode -> GoogleReverseGeocodingQuery (options)

Number 1 is used while getting autocomplete results.
Number 2 is used when you click on a result.
Number 3 is used when you select 'Current Location' to load nearby results.
Number 4 is used when nearbyPlacesAPI='GoogleReverseGeocoding'` is set and you select 'Current Location' to load nearby results.
