Usage

• minimal and round-borders - for webpages with light background color
• minimal-dark and round-borders-dark for webpages with dark background color.

2. Add Geoapify context and provide an apiKey there
3. Add Geoapify Geocoder Autocomplete component

import React, { useState } from 'react'
import { GeoapifyGeocoderAutocomplete, GeoapifyContext } from '@geoapify/react-geocoder-autocomplete'
import '@geoapify/geocoder-autocomplete/styles/minimal.css'

const App = () => {
  ...

  function onPlaceSelect(value) {
    console.log(value);
  }

  function onSuggectionChange(value) {
    console.log(value);
  }

  function preprocessHook(value) {
    return `${value}, Munich, Germany`
  }

  function postprocessHook(feature) {
    return feature.properties.street;
  }

  function suggestionsFilter(suggestions) {
    const processedStreets = [];

    const filtered = suggestions.filter(value => {
      if (!value.properties.street || processedStreets.indexOf(value.properties.street) >= 0) {
        return false;
      } else {
        processedStreets.push(value.properties.street);
        return true;
      }
    })

    return filtered;
  }

  return <GeoapifyContext apiKey="YOUR_API_KEY_HERE">

        placeSelect={onPlaceSelect}
        suggestionsChange={onSuggectionChange}

suggestionsChange	Fired on new suggestions	GeoJSON.Feature[]
onUserInput	Fired on user input	string

Hooks and filters

Name	Description
preprocessingHook	Modify the text to search. For example, if you expect that the user enters a street name you can add a city or postcode to search streets in the city.
postprocessingHook	Modify the text that will be displayed in the input field and suggestions list. For example, you can show only a street name.
suggestionsFilter	Filtering some suggestions. It lets to avoid duplicated results when you modify the address with a post-process hook. For example, suggestions may contain several addresses with the same street name, they will be duplicated when not the whole address but only the street name is shown.
