# React Geocoder Autocomplete

[![Docs](https://img.shields.io/badge/View%20Full%20Documentation-0078D4)](https://geoapify.github.io/react-geocoder-autocomplete/)

The **React Geocoder Autocomplete** component integrates the core [@geoapify/geocoder-autocomplete](https://www.npmjs.com/package/@geoapify/geocoder-autocomplete) library into React.
It provides an easy-to-use React wrapper for the [Geoapify Geocoding Autocomplete API](https://www.geoapify.com/address-autocomplete/), allowing developers to add advanced, localized, and flexible address search functionality to their applications.

## Features

* Simple React integration with a ready-to-use component.
* Fast, responsive incremental search with built-in debounce.
* Localized suggestions with support for multiple languages and country filters.
* Flexible configuration: biasing, filtering, and bounding boxes.
* Customizable design: easily style or theme your component.
* Accessible with keyboard navigation and ARIA support.
* Rich results including coordinates, structured address, and metadata.
* Compatible with React 18–19.

## Quick Start

You'll need a **Geoapify API key** to use the component.

1. Register for a free account at [myprojects.geoapify.com](https://myprojects.geoapify.com/).
2. Create a project to obtain your API key.
3. You can start for free — Geoapify offers a generous [Freemium plan](https://www.geoapify.com/pricing/).

### 1. Install

```bash
npm install @geoapify/geocoder-autocomplete @geoapify/react-geocoder-autocomplete
# or
yarn add @geoapify/geocoder-autocomplete @geoapify/react-geocoder-autocomplete
```

Get a Geoapify API key: [https://myprojects.geoapify.com](https://myprojects.geoapify.com)

### 2. Import styles and components

Import the CSS style file from `@geoapify/geocoder-autocomplete` and the React components from `@geoapify/react-geocoder-autocomplete`:

```tsx
import '@geoapify/geocoder-autocomplete/styles/minimal.css';
import {
  GeoapifyContext,
  GeoapifyGeocoderAutocomplete
} from '@geoapify/react-geocoder-autocomplete';
```

Themes: minimal, round-borders, minimal-dark, round-borders-dark.

### 3. Add GeoapifyContext

Wrap your component with the `GeoapifyContext` and provide your API key:

```tsx
<GeoapifyContext apiKey="YOUR_GEOAPIFY_API_KEY">
  {/* Your components go here */}
</GeoapifyContext>
```

Tip: Store your API key in an environment variable and reference it as `process.env.REACT_APP_GEOAPIFY_KEY` for better maintainability.

### 4. Use the component

Basic:

```tsx
<GeoapifyGeocoderAutocomplete />
```

With events and common options:

```tsx
<GeoapifyGeocoderAutocomplete
  placeholder="Search for an address"
  lang="en"
  limit={8}
  addDetails={true}
  placeSelect={onPlaceSelected}
  suggestionsChange={onSuggestionsChange}
/>
```

```tsx
const onPlaceSelected = (feature) => {
  console.log('Selected:', feature?.properties?.formatted);
};

const onSuggestionsChange = (list) => {
  console.log('Suggestions:', list);
};
```

## Examples

### 1. Basic Address Search

```tsx
<GeoapifyContext apiKey="YOUR_API_KEY">
  <GeoapifyGeocoderAutocomplete
    placeholder="Search for an address"
    placeSelect={onPlaceSelected}
  />
</GeoapifyContext>
```

```tsx

### 2. Restrict Results to Specific Country

```tsx
<GeoapifyContext apiKey="YOUR_API_KEY">
  <GeoapifyGeocoderAutocomplete
    filterByCountryCode={['us']}
    placeSelect={onPlaceSelected}
  />
</GeoapifyContext>
```

Restricts suggestions to a list of countries using ISO country codes.

**Used properties:**
`filterByCountryCode`, `placeSelect`

### 3. Limit Search to Area (Berlin Example)

```tsx
<GeoapifyContext apiKey="YOUR_API_KEY">
  <GeoapifyGeocoderAutocomplete
    filterByRect={{ lon1: 13.0884, lat1: 52.3383, lon2: 13.7611, lat2: 52.6755 }}
    placeSelect={onPlaceSelected}
  />
</GeoapifyContext>
```

This configuration restricts search results to the Berlin area.

**Used properties:**
`filterByRect`, `placeSelect`

### 4. Bias Results by User Location

```tsx
import { useState, useEffect } from 'react';

const [userLocation, setUserLocation] = useState(null);

useEffect(() => {
  navigator.geolocation.getCurrentPosition((pos) => {
    setUserLocation({
      lon: pos.coords.longitude,
      lat: pos.coords.latitude
    });
  });
}, []);
```

```tsx
<GeoapifyContext apiKey="YOUR_API_KEY">
  <GeoapifyGeocoderAutocomplete

    placeSelect={onPlaceSelected}
  />
</GeoapifyContext>
```

};
```

  console.log('Selected POI:', place.properties.name, 'at index', index);
};
```

Enables category-based search for nearby Points of Interest (POIs) below the input field, filtered by category.

**Used properties:**
`addCategorySearch`, `showPlacesByCategoryList`, `placesByCategoryFilter`, `onPlaceByCategorySelect`

### 8. Show Loading Indicator While Searching

```tsx
import { useState } from 'react';

const [loading, setLoading] = useState(false);

<div className="autocomplete-wrapper">
   <GeoapifyContext apiKey="YOUR_API_KEY">
    <GeoapifyGeocoderAutocomplete
      onRequestStart={() => setLoading(true)}
      onRequestEnd={() => setLoading(false)}
      placeSelect={onPlaceSelected}
    />

    addDetails={true}
    placeSelect={onPlaceSelected}
  />

**Used properties:**
`filterByCountryCode`, `biasByProximity`, `addDetails`, `placeSelect`
