Angular 15 Authentication

Authentication is a crucial aspect of any web application, and Angular provides powerful tools to implement it. In this article, we will explore how to create registration and login functionality with role-based access using Angular 15 and a JSON server REST API.

Setup

Before we delve into the implementation details, let’s set up our development environment. Make sure you have Angular 15 and a JSON server REST API installed.

Registration

To implement registration, we need a registration form where users can enter their details. In Angular, we can create a registration component to handle this functionality. The component should have input fields for name, email, password, and role. Upon submission, the component will send a POST request to the server API to create a new user.

Login

For the login functionality, we can create a separate login component. The component should have input fields for email and password. Upon submission, the component will send a POST request to the server API to authenticate the user. If the login is successful, the server will return a JSON Web Token (JWT) that can be stored in the browser’s local storage for future authentication.

Role-based Access

Role-based access control (RBAC) allows us to define different levels of authorization for different user roles. In our JSON server REST API, we can add a “role” field to each user’s data object. In the Angular application, we can create an auth service that handles checking the user’s role and controlling access to different components or routes based on that role.

Conclusion

Implementing registration, login, and role-based access in an Angular 15 application can greatly enhance its security and user experience. With the help of a JSON server REST API, we can easily handle user data storage and authentication. By following the steps outlined in this article, you can create a robust authentication system for your Angular 15 application.
