Angular Routing: Navigating to Different Routes According to User Roles

In today’s post, we'll delve into an important concept for developers creating role-based applications in Angular: routing based on user roles. If you are building an application that has distinct user types, such as admins and customers, it’s crucial to manage what each type of user sees after they log in.

The Problem

Imagine you're working on a mock e-commerce app where user experience is paramount. When a user navigates to the root path of your application (/), various things must happen based on their authentication status and role:

Logged Out Users: Redirect to a sign-in page.

Logged In Customers: Redirect to a customer dashboard.

Logged In Admins: Redirect to an admin dashboard.

Not being able to correctly handle these redirections can lead to confusion and a poor user experience. This is where Angular's routing capabilities and guards come into play.

Solution Overview

To handle user redirection efficiently, we can use Angular's routing and guards feature. Below, I’ll explain how to set this up step by step.

Step 1: Defining Your Routes

Start by defining your application’s routing configurations in the app-routing.module.ts file. Here's an outline of what that looks like:

Step 2: Implementing the Authorization Guard

Next, create an AuthorizationGuard that will determine what path a user should be redirected to based on their role. Below is an example of such a guard:

Step 3: Handling Authentication

In your authentication service (AuthService), ensure that you have a way to determine which user is logged in and their role. This service should have a method like getLoggedInUser() that returns the user object containing their role.

Step 4: Making It Work in the Login Logic

Finally, integrate this guard in your login logic. After successful authentication, redirect users to the appropriate path based on the result from AuthorizationGuard.

Example Workflow

Here’s a brief overview of what the login flow could look like:

User navigates to /:

If not logged in: Redirects to /auth.

If logged in as an admin: Redirects to /admin.

If logged in as a customer: Redirects to /customer.

Conclusion

By utilizing Angular's routing and guards, you can easily control the navigation flow based on the user’s authentication state and role. This not only enhances the security of your application but also improves user satisfaction by providing a tailored user experience.
