📓 How to document the Swagger UI endpoint API

/**
 * @typedef ResponseJSON
 * @property {string} username - user's username - eg: janet
 * @property {string} message - message - eg: This is a authenticated route!
 */
/**
 * Dashboard endpoint only allowed for authenticated users
 * @route GET /api/v1/auth/dashboard
 * @group Auth
 * @returns {ResponseJSON.model} 200
 * @produces application/json
 */
router.get('/dashboard', authenticationMiddleware(), (req, res) => {
    return res.json({
        username: req.session.passport.user.username,
        message: 'This is a authenticated route!'
    });
});

If you are running this boilerplate on you localhost you can see the Swagger UI documentation on: http://localhost:3005/api-docs/.

Note: Check if your port number is the same as your configuration.
