🚀 Usage

🔑 Setup JwtService

final jwtService = JwtService(
  accessTokenSecret: 'my-secret',
  refreshTokenSecret: 'my-refresh-secret',
  issuer: 'dartapi',
  audience: 'api-clients',
);

🧪 Generate Tokens

final accessToken = jwtService.generateAccessToken(claims: {
  'sub': 'user-123',
  'username': 'akash',
});

final refreshToken = jwtService.generateRefreshToken(accessToken: accessToken);

🔍 Verify Tokens

final accessPayload = jwtService.verifyAccessToken(accessToken);
final refreshPayload = jwtService.verifyRefreshToken(refreshToken);

🔒 Use Middleware to Protect Routes

Import middleware

import 'package:dartapi_auth/dartapi_auth.dart';

Apply per-route:

ApiRoute<void, List<UserDTO>>(
  method: ApiMethod.get,
  path: '/users',
  typedHandler: getUsers,
  middlewares: [authMiddleware(jwtService)],
);

📄 Example Use in dartapi CLI Project

bin/main.dart

final jwtService = JwtService(...);
final app = DartAPI();

app.addControllers([
  UserController(jwtService),
  AuthController(jwtService),
]);

UserController

ApiRoute<void, List<UserDTO>>(
  method: ApiMethod.get,
  path: '/users',
  typedHandler: getAllUsers,
  middlewares: [authMiddleware(jwtService)],
);
