Use Radar’s autocomplete component to add address autocomplete to your websites and apps with just a few lines of code. You can check out the autocomplete explorer in the dashboard, or check out a full-page maps demo and store locator demo with an autocomplete component.

​
How it works

To use the autocomplete component, simply initialize the Radar SDK with your publishable key and specify the container to render the input into.

​
Configuration

When creating the autocomplete component, you can provide options to customize the autocomplete behavior, as well as the size and style of the input. Available options include:
NameDefaultPossible valuesDescriptionSDK availability
containerautocompletestring | HTMLElementThe container to render the autocomplete into. You can specify an id of an HTML element or a DOM element. If an <input> is provided as a container, the style of the input will not be modified.Web

maxHeightnullnumber | stringThe max height of the results list, a number (in pixels) or any valid CSS height.Web
nearnullstring | LocationThe location to search near, in the format "latitude,longitude" or { latitude, longitude }. If not specified, the search will automatically be biased based on the client’s IP geolocation.Web, React Native

      Radar.initialize('prj_live_pk_...');

      Radar.ui.autocomplete({
        container: 'autocomplete',
        width: '600px',
        onSelection: (address) => {
          // do something with selected address
        },
      });
    </script>

React

import React, { useEffect, useRef } from 'react';
import Radar from 'radar-sdk-js';
import 'radar-sdk-js/dist/radar.css';

const RadarAutocomplete = () => {
  const autocompleteRef = useRef(null);

  useEffect(() => {
      Radar.initialize('prj_live_pk_...');

      autocompleteRef.current = Radar.ui.autocomplete({
        container: 'autocomplete',
        width: '600px',
        onSelection: (address) => {

    };
  }, []);

  return (
    <div id="autocomplete" />
  );
};

export default RadarAutocomplete;

​
React Native

import { View } from 'react-native';
import { useState, useEffect } from 'react';
import Radar, { Autocomplete } from 'react-native-radar';

Radar.initialize('prj_live_pk_...');

export const App = () => (
  <View>
    <Autocomplete options={
      onSelection: (address) => {
        // do something with selected address
      },
    } />

Use Autocomplete with Radar Maps in React

Below is an example of how you can use Radar Maps with Radar Autocomplete in React. 
import React, { useEffect, useRef } from 'react';
import Radar from 'radar-sdk-js';
import 'radar-sdk-js/dist/radar.css';

const RadarMap = () => {
  const radarInitialized = useRef(false);
  const mapRef = useRef(null);
  const markerRef = useRef(null);
  const autocompleteRef = useRef(null);

  useEffect(() => {
    Radar.initialize('prj_live_pk_...');

    // Create a map
    const map = Radar.ui.map({
      container: 'map',
      style: 'radar-default-v1',
      center: [-73.9911, 40.7342], // NYC
      zoom: 14,
    });
    mapRef.current = map;

    // Add a marker to the map
    const marker = Radar.ui.marker({ text: 'Radar HQ' })
      .setLngLat([-73.9910078, 40.7342465]) // default example.
      .addTo(map);
    markerRef.current = marker;

    // Initialize Radar autocomplete
    autocompleteRef.current = Radar.ui.autocomplete({
      container: 'autocomplete',
      width: '400px',
      onSelection: (address) => {
        const { latitude, longitude } = address;
        console.log('Selected address:', address);

        // Update marker position
        markerRef.current.setLngLat([longitude, latitude]);

        // Center the map on the selected address
        mapRef.current.flyTo({ center: [longitude, latitude], zoom: 14 });
      },
    });
    return () => {
        autocompleteRef.current?.remove();
    };
  }, []);

  return (
    <div style={{ display: 'flex', height: '100vh' }}>
      <div id="autocomplete" style={{ width: '400px', padding: '10px' }} />
      <div id="map" style={{ flex: 1 }} />
    </div>
  );
};

export default RadarMap;
