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.
