??Firebase Auth in .NET MAUI Blazor: User Management Made Easy ??

In this blog, we will explore how to implement user management in your .NET MAUI Blazor hybrid app using Firebase Auth. This guide will provide you with insights on creating, updating, and assigning roles to users, making your application robust and secure. Let’s dive into the details of using Firebase Auth in .NET MAUI Blazor!

Getting Started with User Management ??

Before we jump into the implementation, let's take a look at the overall structure of our application. We will create a user management system that works seamlessly across different platforms including desktop, web, and mobile applications. This system will allow admin users to manage other users effectively.

User Management Interface ??

When you run the application, you will see a user management list displaying users along with their roles. This interface is consistent across all platforms, ensuring a uniform experience for users whether they are on desktop, web, or mobile. Here’s how the interface looks:

User roles are displayed next to each user.

Admin users can edit roles and delete users as necessary.

Updating User Roles ??

To update a user's role, simply click the edit button next to the user. This will populate a form with the user's current information, including their roles. You can remove or add roles as needed and update the user's information. The updated data will reflect across all platforms instantly.

Example of Updating a User

For example, if a user currently has the role of 'admin', you can remove that role and assign a new one like 'HR'. Once you make the changes and click update, the information will be refreshed, and you will see the updated roles.

Cross-Platform Synchronization ??

One of the key features of this user management system is its ability to synchronize data across platforms. For instance, if you update a user’s phone number on the desktop application, the change will be visible on the web and mobile applications as well. This ensures that all users have access to the latest information, no matter which platform they use.

Firebase Setup ??

Before implementing user management, you need to set up Firebase in your application. Here’s a brief overview of how to do that:

Go to the Firebase console and create a new project.

Navigate to the Authentication section and enable Email/Password sign-in method.

Generate a service account key for your project. This key will be used to authenticate requests from your application.

Implementing User Management System ???

Now that Firebase is set up, let’s implement the user management system in our .NET MAUI Blazor app. We will use the Firebase Admin SDK to interact with Firebase Authentication.

Creating User Management Component

We'll start by creating a new Razor component for managing users. This component will handle displaying the user list, updating user details, and assigning roles.

Loading User Data ??

To load user data from Firebase, we will create a method that retrieves the list of users. This can be done using the Firebase Admin SDK with the following code snippet:

var users = await FirebaseAuth.DefaultInstance.ListUsersAsync();        

This method will return a list of user records that you can then bind to your UI.

Adding New Users ?

In addition to updating existing users, you can also add new users to your Firebase project. This can be achieved with a simple form where you can input the user’s email, password, and roles. On submission, the user will be created in Firebase Authentication.

Example Code for Adding Users

await FirebaseAuth.DefaultInstance.CreateUserAsync(new CreateUserRequest
{   

 Email = "[email protected]",

    Password = "securePassword"

});        

Deleting Users ?

To delete a user, you will implement a delete function that can be triggered by an admin. This function will call the Firebase Admin SDK to remove the user based on their unique user ID.

Example Code for Deleting Users

await FirebaseAuth.DefaultInstance.DeleteUserAsync(userId);        

Once the user is deleted, the change will be reflected across all platforms.

Role-Based Access Control (RBAC) ??

Implementing role-based access control is crucial for managing user permissions. You can assign roles such as 'Admin', 'User', and 'HR' to users, which will dictate their access levels within your application.

Assigning Roles

When creating or updating a user, you will assign roles based on the user's responsibilities. This will help ensure that users only have access to the functionalities they need.

Conclusion ??

In this blog, we've covered how to implement user management using Firebase Auth in .NET MAUI Blazor. From creating and updating users to managing roles and ensuring cross-platform synchronization, you now have the knowledge to build a robust user management system.

With Firebase Auth in .NET MAUI Blazor, managing users has never been easier. Start implementing these features in your applications today!
