A Node.js based app that is able to respond to emails sent to Gmail mailbox while we’re out on a vacation.

AutoResponder for Gmail

This Node.js application automatically responds to unreplied emails in your Gmail inbox while you're on vacation.

Introduction

This Node.js application uses the Gmail API to check for new emails in your Gmail inbox, identify unreplied emails, and automatically respond with a predefined message. It also adds a label to the email and moves it to the labeled category. The application repeats this process in random intervals, simulating a vacation auto-responder.

Prerequisites

Before using this application, ensure you have the following:

• Node.js installed on your machine
• A Gmail account
• Google Cloud Platform project with the Gmail API enabled
• API credentials in JSON format (Create credentials)

Installation

1. Clone this repository to your local machine:

     git clone https://github.com/himacharan128/gmailAutoResponder.git

2. Install dependencies:

     npm install

3. Configure Gmail API:

• Enable the Gmail API and download the credentials.json file from the Google Cloud Console.
• Save the credentials.json file in the project directory.

4. Create userSecret.json: Create a userSecret.json file in the project directory with the following structure:

     {
    "installed": {
      "client_id": "<YOUR_CLIENT_ID>",
      "client_secret": "<YOUR_CLIENT_SECRET>",
      "redirect_uris": ["urn:ietf:wg:oauth:2.0:oob", "http://localhost"]
      }
    }

  npm start

Visit http://localhost:8080 in your browser to authenticate and start the auto-responder.
