Flight Auth Service

Overview

The Flight Auth Service is a microservice in the Airline Management system responsible for user registration and role-based authentication. It supports roles such as 'user' and 'admin.' Admins have special privileges, including create, update, and delete functionalities. The service utilizes PostgreSQL as the database, Sequelize as the ORM, bcrypt for password encryption, and jsonwebtoken for generating JWT tokens. The authentication mechanism is based on local storage, and only registered users have access to communicate with other microservices.

Features

• User Registration: Allows users to register for access to the Airline Management system.
• Role-Based Authentication: Implements role-based authentication with 'user' and 'admin' roles.
• Admin Privileges: Admins have access to create, update, and delete functionalities.
• Password Encryption with bcrypt: Secures user passwords by encrypting them before storage in the database.
• JWT Token Generation with jsonwebtoken: Generates JWT tokens for authenticated users.
• Local Storage Authentication: Only registered users with valid JWT tokens have access to communicate with other microservices.

Technologies Used

• Node.js: JavaScript runtime for server-side development.
• Express: Web application framework for Node.js.
• PostgreSQL: Relational database for data storage.
• Sequelize: Promise-based ORM for Node.js and PostgreSQL.
• Sequelize CLI: Command-line interface for Sequelize.
• bcrypt: Library for password hashing and encryption.
• jsonwebtoken: Library for generating JSON Web Tokens (JWT).

     PORT=your_preferred_port
     SYNC_DB=true

4. Run Sequelize Init

   npx sequelize init

5. Inside the config/config.json file make sure to add your local DB username and Password and appropriate DB name.

6. Run Sequelize Create
