Overview of this book

Google Cloud Platform is one of the three major cloud providers in the industry, exhibiting great leadership in application modernization and data management. This book provides a comprehensive introduction for those who are new to cloud development and shows you how to use the tools to create cloud-native applications by integrating the technologies used by Google. The book starts by taking you through the basic programming concepts and security fundamentals necessary for developing in Google Cloud. You'll then discover best practices for developing and deploying applications in the cloud using different components offered by Google Cloud Platform such as Cloud Functions, Google App Engine, Cloud Run, and other GCP technologies. As you advance, you'll learn the basics of cloud storage and choosing the best options for storing different kinds of data as well as understand what site reliability engineers do.

Creating, updating, and showing data in your frontend application

In this section, we will review in detail how to interact with the Firestore database to create, update, obtain, and delete documents within our collections, from the installation of dependencies to the implementation of sample code to cover each of the operations.

Firestore dependencies

In this section, we will use the Firebase Admin library and the Node.js programming language for various examples of integration with Firestore.

To install the Firestore library in a Node.js project, we can use the following command:

npm install --save @google-cloud/firestore

In addition, it is necessary to assign the roles/datastore.owner role to the service account that will be used to run the sample code.

If you need to use another programming language, go to the official Firebase documentation at https://firebase.google.com/docs/firestore.
