### About
App & Flow is a Montreal-based React Native engineering and consulting studio. We partner with the world’s top companies and are recommended by [Expo](https://expo.dev/consultants). Need a hand? Let’s build together. [email protected]
## Installation
```sh
yarn add @appandflow/react-native-google-autocomplete
```
```sh
npm i @appandflow/react-native-google-autocomplete
```
## Usage
The `useGoogleAutocomplete` hook takes 2 arguments
| Arg | Description |
| ------ | ---------------------------------------------------------------------------------------------------------- |
| apiKey | [Your google places api key](https://developers.google.com/maps/documentation/places/web-service/overview) |
| config | optional config object |
# Config object
| Property | Description |
| ------------ | ------------------------------------------------------------------------------------------------------ |
| debounce | optional - default 300 |
| language | optional - default 'en' |
| queryTypes | optional - default address - https://developers.google.com/places/web-service/autocomplete#place_types |
| minLength | optional - default 2 - this is the min length of the term search before start |
| components | optional - A grouping of places to which you would like to restrict your results |
| radius | optional - The distance (in meters) within which to return place results |
| lat | optional - The latitude. If provided, lng is required |
| lng | optional - The longitude. If provided, lat is required |
| strictBounds | optional - Returns only places that are strictly within the region defined by location and radius. |
| proxyUrl | optional - This is required if you want to use the hook in a Web based platform. Since we dont use the Google SDK, the http call will fail because of issues related to CORS unless a proxyUrl is provided |
# Exposed properties
| Property | Description |
| --------------- | -------------------------------------------------------------------------- |
| clearSearch | Clears your current search |
| isSearching | Boolean that lets you know the search is underway |
| locationResults | The array of results of the search |
| searchDetails | Function that lets you get more details, good for when you select a result |
| searchError | Errors that could occur during search |
| term/setTerm | The term is the search term used, it's set using setTerm |
# Code example
This is a minimalistic functionnal snippet that returns 3 results for your search.
Clicking on a result logs the details of that result.
```ts
const { locationResults, setTerm, clearSearch, searchDetails, term } =
useGoogleAutocomplete(API_KEY, {
language: 'en',
debounce: 300,
});
return (
{locationResults.slice(0, 3).map((el, i) => (
{
const details = await searchDetails(el.place_id);
console.log(JSON.stringify(details, null, 2));
}}
>
{el.structured_formatting.main_text}
))}
);
```
## Results
`locationResults` returns the following. The maximum result set by Google is 5 locations by query.
```js
export interface GoogleLocationResult {
description: string;
id: string;
matched_substrings: Array<{
length: number;
offset: number;
}>;
place_id: string;
reference: string;
structured_formatting: {
main_text: string;
secondary_text: string;
main_text_matched_substrings: Array<{
length: number;
}>;
};
terms: Array<{
offset: number;
value: string;
}>;
types: string[];
}
```
When calling the searchDetails this is what you get
```js
export interface GoogleLocationDetailResult {
adr_address: string;
formatted_address: string;
icon: string;
id: string;
name: string;
place_id: string;
scope: string;
reference: string;
url: string;
utc_offset: number;
vicinity: string;
types: string[];
geometry: {
location: {
lat: number;
lng: number;
};
viewport: {
[type: string]: {
lat: number;
lng: number;
};
};
};
address_components: Array<{
long_name: string;
short_name: string;
types: string[];
}>;
}
```
## Typings
You can import both result typing if you need for flow or typescript.
```js
import {
GoogleLocationDetailResult,
GoogleLocationResult,
} from 'react-native-google-autocomplete';
```
## Restrict by country
If you want to restrict the search by country you can add this as a props `components="country:ca"`. This here would example restrict it to Canada only.
