Reference Documentation

The googlemaps/google-maps-services-js API provides a comprehensive set of functions and methods that can be used in Node.js development. This API helps users incorporate Google Maps directly into their applications, including geocoding, directions, and distance matrixes.

One of the functions available is the Geocoding API, which is used to convert street addresses into geographical coordinates, and vice versa. This API can be helpful in several applications, such as determining the location of a business or finding the closest store to a user’s location.

Another function provided by this API is the Directions API, which allows developers to request directions between two or more points, using various modes of transportation. This API can be used in various applications, such as building a ride-sharing app or planning a road trip.

The Distance Matrix API is another function available, which calculates travel distance and time between multiple points. This API can be used in various applications, such as determining the nearest store location from a user’s current location.

All of these functions and methods provided by the googlemaps/google-maps-services-js API are easily integrated into Node.js development, making it a useful tool for developers looking to incorporate Google Maps into their applications.

Developing with googlemaps/google-maps-services-js

Google Maps API Web Services can be directly integrated into your Node.js application using googlemaps/google-maps-services-js library. Here are some best practices and tips to keep in mind while developing with googlemaps/google-maps-services-js:

API key: It is necessary to have a valid API key to access the Google Maps API. Ensure that you have generated an API key for your application and pass it to the googlemaps object while initializing the client.
Rate Limits: Plan your application’s request load and avoid exceeding the API usage limits as per Google Maps API terms of service. Use client-side strategies like caching server responses and minimizing the number of requests to the API.
Error Handling: The API can return errors while processing a request. Design your application logic to handle response errors and retry the request after a period of time.
Localization: The Google Maps API supports multiple languages and regions. Identify your application’s target audience and set the appropriate localization parameters in your requests.
Testing: Use testing frameworks like Mocha and Chai to automate Unit and Integration testing of your code. Build necessary tests to validate the requests and responses to the API.

Here is an example code snippet illustrating the use of the googlemaps library in a Node.js application:

const googleMapsClient = require('@google/maps').createClient({
  key: 'YOUR_API_KEY',
  Promise: Promise
});

googleMapsClient.directions({
  origin: 'Sydney',
  destination: 'Perth',
  mode: 'driving'
})
.then((response) => {
  console.log(response.json.routes[0].legs[0]);
})
.catch((err) => {
  console.log(err);
});

Migration: from @google/maps to @googlemaps/google-maps-services-js

Old (@google/maps):

If you are using @google/maps, it is time to switch to @googlemaps/google-maps-services-js as the former has been deprecated. The primary difference between the two is that @googlemaps/google-maps-services-js brings Google Maps API Web Services to your Node.js application.
To migrate, first, remove “@google/maps” from your package.json file and replace it with “@googlemaps/google-maps-services-js.” Next, install the library using npm. Finally, update your code to use the new library.
Ensure that your API key has permissions for the specific APIs you are using with the new library.
After the migration, ensure that all existing functionalities work as intended.

New (@googlemaps/google-maps-services-js):

The new @googlemaps/google-maps-services-js library brings more features and functionalities to your Node.js development. In addition to geocoding and directions, the library now supports distance matrix, timezone, elevation, and roads API.
The library is also now structured to follow the same organization as official Google Maps API documentation. This can make learning and utilizing the library easier for developers.
The aforementioned new features help to make development with the library more efficient and convenient.

Premium Plan Authentication

The Google Maps API offers various authentication methods, including the Premium Plan Authentication, which requires an API key with a Premium Plan license. This authentication method provides additional benefits such as higher usage quotas, advanced analytics and support, and enhanced security features. To set up Premium Plan Authentication for googlemaps/google-maps-services-js, follow these steps:

1. Obtain a Premium Plan license and a valid API key from the Google Cloud Console.

2. Install googlemaps/google-maps-services-js package in your Node.js application using npm.

3. Include the API key in your requests by adding the premium_plan query parameter, like this:

const googleMapsClient = require('@google/maps').createClient({
  key: 'YOUR_API_KEY',
  premium_plan: true
});

4. Use the Google Maps API web services for geocoding, directions, and other features as needed in your application.

Note: Ensure that you keep your API key secure, as it can be used to access your billing account and other sensitive information.
