How to Redirect to a Specific Path in Angular After Login

Navigating through web applications seamlessly is crucial for providing users with a great experience. One common scenario in applications is requiring users to log in first before accessing specific routes. This guide will walk you through how to implement a redirection in Angular after a successful login, allowing users to return to their intended path seamlessly.

Understanding the Problem

In a typical Angular application, you might encounter a situation where users are trying to access protected routes without being authenticated. For instance, if a user tries to access the URL http://localhost:4200/office/profile, they should first be redirected to the login page. After successfully logging in, they should be sent back to their initial destination.

This can be accomplished through Angular's routing mechanism by using a service called an AuthGuard. In this post, we will look into how to implement this functionality effectively.

Setting Up the AuthGuard

Step 1: Create the AuthGuard Service

First, you need to set up an AuthGuard service to handle the routing logic. Here's how to create the service:

Step 2: Implement the CanActivate Method

Next, we need to implement the logic to check if the user is authenticated. If not, we will redirect them to the appropriate login page. The modified code looks like this:

How It Works

Authentication Checks: The canActivate method checks if the user is authenticated by invoking isAuthenticateManagement() and isAuthenticate() methods from the AuthService.

Redirection: If the user is not authenticated, they are redirected to either a management login page (/auth/mp_access) or a general login page (/auth/sign_in).

Query Params: The original route they tried to access is passed as a query parameter (redirectURL). This allows the application to redirect the user back to that route after successful authentication.

Conclusion

By implementing the AuthGuard service and utilizing Angular's routing capabilities, you can effectively manage user access and improve the user experience. This method ensures that users can return to the path they intended to visit after logging in, maintaining the integrity of your application’s navigation.

With the above implementation, you will not only restrict access to unauthorized users but also guide your authenticated users back to their desired routes, enhancing usability and satisfaction.

Happy coding!
