Built using Node.js, Express, and Sequelize, this system supports functionalities for both regular users and administrators, ensuring efficient handling of train schedules, seat availability, and user bookings.

• User Authentication: Secure login and registration functionality for users.
• Train Management: Administrators can add trains and update seating capacities.
• Seat Booking: Users can check seat availability and book seats on trains.

To run this project locally, you will need Node.js and PostgreSQL installed on your machine. Optionally, you can use Docker for running PostgreSQL.

git clone https://github.com/mayank2808sharma/IRCTC-backend
cd IRCTC-backend

2. Install Dependencies

npm i

3. Set Up Environment Variables

Create a .env file in the root directory and update it with your database and authentication configurations as follows:

PORT= 3000
DB_HOST = hostname 
DB_USER = username for the database
DB_PASSWORD = password for the database
DB_NAME = name of the database
JWT_SECRET = secret key used to sign and verify JSON Web Tokens

4. Database Setup

Make sure your PostgreSQL database is running and the credentials in .env match your database info. Run the following command to set up your database tables:

npm run setdb

5. Start the Server

npm start

This will start the server on http:https://localhost:3000.
