Google Calendar Integration with Express.js

This is a simple Express.js application that integrates with the Google Calendar API. It allows you to authenticate, retrieve events, create new events, and fix meetings within a specified time range.

Prerequisites

Before running the application, make sure you have the following:

Node.js and npm installed
Google API credentials (Client ID, Client Secret, and API Key)
Redirect URL configured in the Google Cloud Console for OAuth2 authentication

Getting Started

Clone the repository:

git clone https://github.com/ankitrekha01/google-calendar.git

Install dependencies:
```
npm install
```

Configure your environment variables:

Create a .env file in the project root and add the following:

CLIENT_ID=your-client-id
CLIENT_SECRET=your-client-secret
API_KEY=your-api-key
REDIRECT_URL=your-redirect-url
PORT=5000

Run the application:
```
npm start
```
Visit http://localhost:5000/google in your browser to authenticate with Google Calendar.

Endpoints

/google: Initiates the Google OAuth2 authentication flow.
/google/redirect: Handles the OAuth2 callback and sets the access token.
/allevent: Retrieves all events from the authenticated user's Google Calendar.
/create-event: Creates a new event within a specified time range, avoiding conflicts with existing events.
/fix-meeting: Inserts a new event into the Google Calendar using the /create-event endpoint.

Usage

Visit http://localhost:5000/google to authenticate with Google Calendar.
Use the provided endpoints to interact with the Google Calendar API.
Customize the application logic in meetings.js and endpoints in app.js as needed.

Important Notes

Ensure that your Google API credentials are correctly configured.
The application uses an in-memory storage for the access token. In a production environment, consider using a secure token storage mechanism.
