Features

• Customizable Address Input — Easily embed address autocomplete fields anywhere in your web app. Attach them to any HTML container (e.g., a DIV) and style them freely.
• Powered by Geoapify APIs — Connects seamlessly to the Geoapify Address Autocomplete API for real-time, global address suggestions. Optionally, you can integrate or extend it with other geocoding APIs for hybrid use cases.
• Advanced Search Customization — Fine-tune autocomplete behavior with flexible filters and bias settings (country, circle, rectangle, proximity) for highly relevant and localized results.
• Structured Address Forms — Use the type parameter to build structured input fields (e.g., country, city, postcode, street, or amenity), perfect for checkout or registration forms.
• Category & POI Search — Enable category-based lookups such as restaurants, hotels, or gas stations. When active, category suggestions appear alongside address results for richer, context-aware searches.
• Built-in Places List — Display categorized places directly in your interface with data from the Geoapify Places API. The list includes name, address, and opening hours, plus lazy loading for more results.
• Place Details Integration — Optionally fetch additional information and geometries from the Geoapify Place Details API — ideal for showing boundaries, polygons, or rich place context.
• Fully Customizable Look & Feel — Choose from four built-in light/dark themes or override styles using provided CSS classes for seamless integration with your app design.
• Zero Dependencies — No external libraries required. Clean, lightweight, and framework-agnostic by design.

Quick Start

1. Install the library

You can install the Geoapify Geocoder Autocomplete package using your preferred package manager:

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

Alternatively, load it directly from a CDN:

<link rel="stylesheet" href="https://unpkg.com/@geoapify/geocoder-autocomplete/styles/minimal.css" />
<script src="https://unpkg.com/@geoapify/geocoder-autocomplete/dist/index.min.js"></script>

Here’s the improved section for step 2:

2. Get a Geoapify API Key

Visit Geoapify.com to sign up and get your free API key.

Geoapify offers a Free Plan that includes up to 3,000 address search requests per day, making it ideal for testing, prototyping, and small projects.

You can explore all available plans and usage limits on the Geoapify Pricing page.

3. Add the component to your project

Create an HTML container and initialize the autocomplete:

<!-- Container must have position: relative (or absolute) -->
<div id="autocomplete" style="position: relative;"></div>

import { GeocoderAutocomplete } from '@geoapify/geocoder-autocomplete';

const container = document.getElementById('autocomplete');

// When using CDN, access the control as `autocomplete.GeocoderAutocomplete`
const autocomplete = new GeocoderAutocomplete(container, 'YOUR_API_KEY', {
  placeholder: 'Enter address...',
  lang: 'en',
  limit: 5
});

This creates an interactive input that fetches address suggestions in real time. You can customize its behavior through the constructor and available options.

4. Listen for events

Subscribe to events to react to user selections or API updates:

autocomplete.on('select', (feature) => {
  console.log('Selected location:', feature);
});

autocomplete.on('suggestions', (suggestions) => {
    console.log('Address suggestions:', suggestions);
});

autocomplete.on('open', () => console.log('Dropdown opened'));
autocomplete.on('close', () => console.log('Dropdown closed'));

See the full list of available events in the Events Reference.

For critical use cases like shipping or delivery, always verify locations using map previews or reverse geocoding (e.g., the Geoapify Reverse Geocoding API).
