####Steps to develop this project:

1. Authentication (login & signup) with email & password + JWT token generation (expiry - 2 days):

   For authentication, I created a /login and /signup endpoint in your Node.js/Express.js application that accepts email and password as input and generates a JWT token on successful authentication.This implementation uses the bcrypt library to hash and compare passwords, and the jsonwebtoken library to generate JWT tokens. The POST /signup endpoint inserts a new user into the users table in the database with the hashed password. The POST /login endpoint queries the users table for the user with the specified email, compares the password with the hashed password, and generates a JWT token on successful authentication.

2. I have created a /students endpoint in your Node.js/Express.js application that accepts a CSV file upload and inserts unique rows into the students table in the database using csv-parser and fast-csv libraries.

3. This implementation queries the students table in the database for all the students and returns a JSON array of the students.

4. This implementation queries the students table in the database for all the students, converts them to a CSV file using the json2csv library, and returns the CSV file as a response. The Content-disposition header is set to force the browser to download the file instead of displaying it. The Content-Type header is set to text/csv.
