A lightweight wrapper around Google Places Autocomplete and Directions APIs.
npm install react-google-geocodingreact-google-hooks is a React library that makes it easy to work with Google Places and Geocoding APIs. It provides simple, ready-to-use hooks for fetching place predictions and geocoding information, helping developers quickly integrate these features into their applications. The library is also designed with future expansion in mind, with plans to add support for more Google services through additional hooks.
Install the library using npm:
``bash`
npm install react-google-hooks
Make sure you have an API key from Google Cloud Console with access to the Places API and Geocoding API.
Include the Google Maps API script in your index.html file:
`html`
async
defer
>
Replace YOUR_API_KEY with your actual API key.
The library currently supports the following hooks:
1. usePlacePredictions - Fetches place predictions based on a query.
2. useDirections - A service for computing directions between two or more places.
HookThe usePlacePredictions hook allows you to get autocomplete predictions based on user input.
It's ideal for enhancing forms or search inputs with location suggestions.
The hook accepts an object with the following properties:
| Parameter | Type | Required | Default | Description |
| ---------------------- | ------------------------------------------------------------------------------------------------------------- | -------- | ----------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| input | string | Yes | N/A | The text string on which to search for predictions. |inputOffset
| | number | No | N/A | A zero-based Unicode character offset of input indicating the cursor position. Defaults to the length of the input if not specified. |language
| | string | No | Browser's language preference | The language in which to return results. Results may be mixed if input language differs from specified language or translation isn't available. |includedPrimaryTypes
| | PlaceType[] | No | All Place types | An array of up to 5 primary place types (e.g., ['restaurant']). If no types are specified, all Place types are returned. |includedRegionCodes
| | RegionCode[] | No | N/A | An array of up to 15 CLDR two-character region codes to filter results. If combined with locationRestriction, results are within the intersection. |locationBias
| | google.maps.LatLng, google.maps.LatLngLiteral, google.maps.LatLngBounds, google.maps.Circle, string | No | IP-based | Bias results to a specific location. At most one of locationBias or locationRestriction should be set. |locationRestriction
| | google.maps.LatLngBounds, google.maps.LatLngBoundsLiteral | No | IP-based | Restrict results to a specific location. At most one of locationBias or locationRestriction should be set. |origin
| | google.maps.LatLng, google.maps.LatLngLiteral | No | N/A | The origin point for calculating geodesic distance to the destination. If omitted, geodesic distance will not be returned. |region
| | RegionCode | No | N/A | A CLDR two-character region code affecting address formatting, result ranking, and returned results. Does not restrict to the specified region. |sessionToken
| | google.maps.places.AutocompleteSessionToken | No | N/A | A token identifying an Autocomplete session for billing purposes. Must generate a new token for each session to avoid incorrect billing. |location
| | google.maps.LatLng | No | N/A | Location for prediction biasing. Predictions will be biased towards the given location and radius. Alternatively, bounds can be used. Deprecated as of May 2023. Use locationBias and locationRestriction instead. |radius
| | number | No | N/A | The radius of the area used for prediction biasing in meters. Must always be accompanied by a location property. Alternatively, bounds can be used. Deprecated as of May 2023. Use locationBias and locationRestriction instead. |bounds
| | google.maps.LatLngBounds, google.maps.LatLngBoundsLiteral | No | N/A | Bounds for prediction biasing. Predictions will be biased towards, but not restricted to, the given bounds. Both location and radius will be ignored if bounds is set. Deprecated as of May 2023. Use locationBias and locationRestriction instead. |
An object containing the following properties:
| Property | Type | Description |
| ------------- | --------- | --------------------------------------------------------------------------------------------------------------- |
| predictions | Array | An array of place prediction objects from the Google Places API. |isLoading
| | boolean | Indicates if the API request is in progress. |status
| | string | The status of the request, which is a key of google.maps.places.PlacesServiceStatus or null if unavailable. |
Below is a basic implementation example using the usePlacesPredictions hook:
`jsx
import React, { useState } from "react";
import { usePlacePredictions } from "react-google-hooks";
const PlacesAutocompleteExample = () => {
const [query, setQuery] = useState("");
const { predictions, isLoading, status } = usePlacePredictions({
input: "Shimla",
language: "en",
});
return (
Loading...
}export default PlacesAutocompleteExample;
``
- Ensure that the Google Maps JavaScript API is correctly loaded before using this hook.
- Make sure your API key has the necessary permissions for the Places and Geocoding APIs.
More hooks and features may be added in future versions. If you have any suggestions or encounter any issues,
feel free to open a GitHub issue.
