Setting Up Google Cloud Project

• Create a Project: Go to the Google Cloud Console, create a new project, or select an existing one.
• Enable Google Calendar API: Navigate to the API & Services dashboard, click on Enable APIs and Services, and enable the Google Calendar API.
• Create OAuth Credentials: Go to the Credentials tab and create OAuth 2.0 credentials. You will need to specify the authorized redirect URIs. Download the credentials.json file, which contains your client ID and client secret.

While developing a project with numerous functionalities, the work of a developer will be much easier by making use of APIs for minor tasks and actually focusing on the purpose of the application. Instead of coding your own logic for storing calendar attributes, user permissions, and event management details, we can use Google Calendar API which comes with integrated security and calendar modules. We will be saved from the hassle of coordinating overlapping events, sending reminders, notifications, etc.

This article covers the integration of Google Calendar API in the NodeJS application and creating new events with service account authentication. Our aim is to integrate Google Calendar services in the NodeJS application. We need to test whether calendar methods are functioning in our backend NodeJS app with proper error handling mechanisms in case of wrong credentials or lack of permissions given to the user. The 2 functions of the calendar which are integrated into this project are event view and add events.

Integrating Google Calendar into a Node.js application allows you to create, modify, and manage calendar events programmatically. This can be useful for various applications, such as scheduling software, personal organizers, or any app that needs to manage events. In this article, we will walk through the steps required to integrate Google Calendar in a Node.js application.

Prerequisites:

• Node.js
• Google Cloud
• OAuth 2.0 Credentials
