Task Management System with Spring Boot Angular | Create Storage Service & Role Base Navigation |#13

In this tutorial, we'll explore how to implement user authentication and role-based navigation in an Angular application. Here's what you'll learn:

1. User Authentication with Storage Service: We'll start by creating a Storage Service to handle the storage and retrieval of user details and tokens in the local storage of the browser. You'll learn how to securely manage user authentication data and maintain user sessions across multiple pages.

2. Role-Based Navigation: We'll implement functionality to navigate users to different components based on their roles. Using Angular's routing capabilities and user role information stored in local storage, we'll ensure that users are directed to the appropriate dashboard component for the admin and employee modules.

3. Handling Unauthorized Access: We'll implement error handling mechanisms to manage unauthorized access attempts and redirect users to the login page or display appropriate error messages.

By the end of this tutorial, you'll have a comprehensive understanding of implementing user authentication and role-based navigation in Angular applications. Whether you're building a project or enhancing an existing one with user authentication features, this tutorial will equip you with the knowledge and skills to create secure and role-aware applications. Let's dive in and elevate the security and user experience of your Angular application!
