Automated Vacation Email Sender Project

Description

This project automates sending out email notifications to your contacts while you're on vacation. Leveraging Node.js and the Google Gmail API, it offers the following features:

Features:

1. Automatic email sending: Based on pre-defined vacation dates, the project automatically sends notifications to your mailing list.
2. Personalized communication: Customize email content with a personalized message and vacation details.
3. Label handling: Define specific labels in Gmail to identify applicable emails and only respond to those while out of office.
4. Reply logic (optional): Implement replying to certain emails with pre-composed responses, further automating communication.

Components:

1. Node.js application: Built using Express for creating server-side APIs and integrating with the Google Gmail API.
2. Google Gmail API: Provides access to manage your Gmail account and send emails programmatically.
3. .env file: Stores sensitive information like API keys and email credentials securely.
4. Scheduler (optional): Utilizes node-schedule to automatically trigger email sending on chosen vacation dates.

Benefits:

• Efficiency: Saves time and effort by automatically sending notifications instead of manually composing and sending emails before and after your vacation.
• Professionalism: Provides a professional, organized way to inform your contacts about your absence.
• Peace of mind: Ensures everyone who needs to know is informed while you're away.

Optional Enhancements that can be tried:

• Integrate with calendar: Automatically populate vacation dates from your calendar for a smoother workflow.
• Dynamic content: Customize content based on sender or email content for more personalized responses.
• Tracking and metrics: Implement email delivery tracking and analytics for insights into communication effectiveness.

Other possible improvements Enhanced logging :

• Provide more detailed error messages, including specific thread IDs or message IDs for easier debugging. Informative error messages:
• Include user-friendly error messages when replying fails, potentially suggesting troubleshooting steps. Retries or fallbacks:
• Implement retry mechanisms for transient errors or consider alternative actions (e.g., logging errors to a file for later review).

Features and Customization:

• Flexible trigger conditions: Allow users to customize the criteria for sending automated replies (e.g., based on keywords, senders, content, or other parameters).
• Personalized email content: Enable dynamic generation of reply content based on user input or data from external sources.
• User-friendly configuration: Provide an intuitive interface for users to configure reply settings, triggers, and content.

Code Structure:

• Modularization: Refactor code into smaller, focused functions for better readability and maintainability.
• Asynchronous operations: Use promises or async/await syntax for smoother handling of asynchronous tasks.
• Environment variables: Consider using environment variables for configuration settings (e.g., label names, subject lines) to enhance flexibility and avoid hardcoding values.

Setup Instructions

Prerequisites:

Node.js and npm (or yarn) installed on your system.

1. Clone the repository:

git clone https://github.com/himanshupatel457/Gmail-auto-replier.git

2. Navigate to the project directory:

   cd Gmail-auto-replier

3. Install the required dependencies:

   npm install

Configuration

1. In your project's root directory, locate the keys.env file.

2. Create a copy of this file and name it keys.env. This new file will hold your sensitive information.

3. Open the .env file in a text editor and replace the placeholder values with your actual credentials and details:

   PORT = 3000 // Replace with your desired port number
   GOOGLE_CLIENT_ID = YOUR_GOOGLE_CLIENT_ID
   GOOGLE_CLIENT_SECRET = YOUR_GOOGLE_CLIENT_SECRET
   REDIRECT_URI = https://developers.google.com/oauthplayground // Or your specific redirect URI
   REFRESH_TOKEN = YOUR_REFRESH_TOKEN
   LABELNAME = Vacation // Replace with the label you want to monitor
   SUBJECT = I'm currently on vacation // Replace with your desired email subject

   Explanation of variables:

   • PORT: The port number where your Node.js application will listen for incoming requests.
   • GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET: Credentials obtained from the Google Cloud Platform to access the Gmail API.
   • REDIRECT_URI: The URI that users will be redirected to after authorization with Google.
   • REFRESH_TOKEN: A long-lived token used to authenticate with the Gmail API without requiring user interaction each time.
   • LABELNAME: The name of the Gmail label that you want to filter emails for.
   • SUBJECT: The subject line to be used for the automated vacation emails.
