This project is a Node application that sends an automated reply to new #UNREAD and #PERSONAL tagged emails. It is built using NodeJS, Express, Google OAUTH, Nodemon.

The following packages were used during the development of the Node App

1. express
2. @google-cloud/local-auth (Authentication purpose)
3. googleapis (Authentication purpose)
4. nodemon (Running the server continously).

The main methodology that has been used can be divided into 2 parts :-

1. Authentication - First of all we need to authenticate the user and get access to the users email to proceed.
2. Reading User emails - To get all the emails that the authenticated user has recieved in the previous 1 Hour.
3. Checking for new emails - We need to check if the email is off type no-reply then we dont need to send any reply.
4. Checking if the user has already replied - We need to check if the user has already replied if they have we dont need to send the reply to the same email again.
5. Constructing the message and sending - We need to construct the message that we want to send and then proceed to send the email and then return.

I think there are a lot of improvements that could have been made some of them are:-

1. The app doesn't has a solid way to diffrentiate between different kinds of do not send reply.
2. The app can only reply to emails that were sent with PERSONAL tag this is because we don't have a way of diffrentiating between do not send reply and professional emails cause there may be a lot of emails which are professional but at the same time of do not send reply.
