NestJS Authentication with JWT

This repository demonstrates how to implement user authentication in a NestJS application using JWT (JSON Web Tokens). The project is designed to provide a clean and modular structure for authentication and authorization processes.

Features

• User Authentication: Secure user login with JWT.
• Registration System: Allows users to create accounts.
• Role-Based Authorization: Define and manage user roles.
• Validation: Ensures proper input data for registration and login.
• Environment Configuration: .env file for managing sensitive configurations.
• Scalable Structure: Modular and extensible for adding more features.

Tech Stack

• NestJS: Framework for building scalable server-side applications.
• JWT: Secure token-based authentication.
• TypeScript: Strongly typed programming language for better development experience.

Getting Started

Prerequisites

Ensure you have the following installed on your system:

• Node.js (v16 or later)
• npm or Yarn
• A compatible database (e.g., PostgreSQL)

Installation

1. Clone the repository:

   git clone https://github.com/ismetcanbyk/NestJs-Auth-Jwt.git
   cd NestJs-Auth-Jwt

2. Install dependencies:

   npm install

3. Set up environment variables:

   Create a .env file in the project root and configure the following variables:

   DATABASE_URL=<your_database_url>
   JWT_SECRET=<your_jwt_secret>
   PORT=8082

Running the Application

1. Start the development server:

   npm run start:dev

2. Access the API at http://localhost:8082.

Testing

Run the test suite:

npm run test

API Endpoints

• POST /auth/register: Register a new user.
• POST /auth/login: Authenticate a user and return a JWT.
• GET /profile: Access the authenticated user's profile (requires valid JWT).

Folder Structure

• src/auth: Contains authentication logic, guards, and strategies.
• src/users: User entity and service for user management.
• src/common: Shared modules, pipes, and filters.
