How to Route Components Dynamically Based on User Access in Angular

Building web applications often requires providing different views or functionalities based on user roles. In Angular, this can be achieved seamlessly by conditionally rendering components based on the user's access level. This guide explores a common scenario: displaying either a user or an admin component when accessing the same route path.

The Problem: Dual Access on the Same Route

You may have a home route utilized by both regular users and admin users. The challenge arises when you want to display the UserComponent to standard users and AdminComponent to admin users, all while maintaining a clean and efficient routing structure.

Here’s an example of what you might currently have in your routing setup:

However, you may feel uncertain about how best to toggle between UserComponent and AdminComponent based on the user’s role. Let's explore a solution to achieve this dynamic routing based on access.

The Solution: Dynamic Component Rendering

To solve this, we'll utilize Angular’s structural directives and dependency injection to dynamically determine which component to render based on the user’s role. In this case, you will manage the HTML structure within your HomeComponent. Here’s how to implement it step-by-step:

1. Update HomeComponent HTML

You will leverage Angular’s *ngIf directive to conditionally render the components. Here’s how your HTML can look:

In this snippet:

The *ngIf directive checks the value of isAdmin.

If isAdmin is true, the AdminComponent will be rendered.

If not, Angular renders the content inside the <ng-template> marked by # userHome, showing the UserComponent instead.

2. Update HomeComponent TypeScript

Next, you'll need to manage the role-checking logic within your TypeScript file. Here’s an example of how to set this up:

In this part:

We import UserService, which contains the logic for determining whether the logged-in user is an admin.

The isAdmin property is set in the component constructor based on the data fetched from UserService. This boolean value then decides which component gets rendered.

3. Conclusion

This approach allows you to manage user access elegantly and efficiently, enhancing the user experience while keeping your routing logic intact. By implementing this dynamic component rendering based on user roles, you ensure that users see the content they’re authorized to access without compromising the application’s structure.

Now you're all set to provide a tailored experience for users and admins alike in your Angular application!

With these techniques at your disposal, you're empowered to create more versatile applications that respect user permissions and contribute to a better overall user experience.
