3. Set up environment variables:

   Create a `.env` file in the root directory and add your environment variables. Refer to the `.env.example` file for required variables.

Usage

Generate Token

To generate a JWT token, use the `generateToken` method. Here's an example:

```typescript import { AuthService } from './auth/auth.service';

const authService = new AuthService(); const token = authService.generateToken({ userId: 123, username: 'exampleUser' }); console.log(token); ```

Verify Token

To verify the validity of a JWT token, use the `verifyToken` method. Here's an example:

```typescript import { AuthService } from './auth/auth.service';

const authService = new AuthService(); const isValid = authService.verifyToken(token); console.log(isValid); ```

Configuration

Configure your environment variables in the `.env` file. The following variables are required:

• `JWT_SECRET` - Secret key used for signing JWT tokens
• `JWT_EXPIRATION` - Token expiration time (e.g., '1h' for 1 hour)
