Exploring the Wonders of Google Maps JavaScript API Places Library - A Journey Around the Eiffel Tower

Google Maps has long been a go-to solution for digital map users around the globe. Its JavaScript API, particularly the Places Library, offers an array of functions that can significantly enhance the user experience in web applications. Today, let’s embark on a digital tour around one of the world’s most iconic landmarks - the Eiffel Tower in Paris - and explore how the findPlaceFromQuery, nearbySearch, textSearch, and getDetails functions of the Places Library can be utilized.

1. Finding the Eiffel Tower with findPlaceFromQuery

The findPlaceFromQuery function is perfect for pinpointing a specific location on the map. It’s particularly useful when your users know the name of the place but not its exact location. Let’s see it in action:

let map;
let service;
let infowindow;

function initMap() {
  const paris = new window.google.maps.LatLng(48.8566, 2.3522);

  infowindow = new window.google.maps.InfoWindow();
  map = new window.google.maps.Map(
    document.getElementById('map'), {center: paris, zoom: 15});

  const request = {
    query: 'Eiffel Tower',
    fields: ['name', 'geometry']
  };

  service = new window.google.maps.places.PlacesService(map);
  service.findPlaceFromQuery(request, function(results, status) {
    if (status === window.google.maps.places.PlacesServiceStatus.OK) {
      for (let i = 0; i < results.length; i++) {
        createMarker(results[i]);
      }
      map.setCenter(results[0].geometry.location);
    }
  });
}

function createMarker(place) {
  const marker = new window.google.maps.Marker({
    map: map,
    position: place.geometry.location
  });

  window.google.maps.event.addListener(marker, 'click', function() {
    infowindow.setContent(place.name);
    infowindow.open(map, this);
  });
}

In this example, we’re searching for “Eiffel Tower” and the map zooms in on the location with a marker.

2. Discovering Nearby Attractions with nearbySearch

The nearbySearch function is fantastic for exploring what’s around a specific location. It’s ideal for finding attractions, restaurants, or hotels near the Eiffel Tower:

function findNearbyPlaces() {
  const eiffelTower = new window.google.maps.LatLng(48.8584, 2.2945);
  const request = {
    location: eiffelTower,
    radius: '500',
    type: ['restaurant']
  };

  service = new window.google.maps.places.PlacesService(map);
  service.nearbySearch(request, callback);
}

function callback(results, status) {
  if (status === window.google.maps.places.PlacesServiceStatus.OK) {
    for (let i = 0; i < results.length; i++) {
      createMarker(results[i]);
    }
  }
}

This code snippet will reveal restaurants within 500 meters of the Eiffel Tower, showcasing local dining options.

3. Broad Searches with textSearch

When your search is more open-ended, textSearch is the ideal function. It’s great for broader queries like “best viewing spots in Paris”:

function textSearchPlaces() {
  const request = {
    location: paris,
    radius: '1000',
    query: 'best viewing spots in Paris'
  };

  service = new window.google.maps.places.PlacesService(map);
  service.textSearch(request, callback);
}

This function returns a list of places based on the textual search query, providing users with a variety of options.

4. Getting In-Depth with getDetails

Finally, the getDetails function is perfect for when you need more information about a specific place. Here’s how you can use it to get detailed information about the Eiffel Tower:

function getPlaceDetails() {
  const request = {
    placeId: 'ChIJLU7jZClu5kcR4PcOOO6p3I0',
    fields: ['name', 'formatted_address', 'place_id', 'geometry']
  };

  service = new window.google.maps.places.PlacesService(map);
  service.getDetails(request, function(place, status) {
    if (status === window.google.maps.places.PlacesServiceStatus.OK) {
      createMarker(place);
      infowindow.setContent('<div><strong>' + place.name + '</strong><br>' +
        'Place ID: ' + place.place_id + '<br>' +
        place.formatted_address + '</div>');
      infowindow.open(map, marker);
    }
  });
}

With this function, you can offer users detailed information, such as the address and unique Place ID of the Eiffel Tower.
