Blazor Login Page Example

Web Development Software

Blazor is a fantastic framework for building web applications using C# and .NET. It allows developers to create interactive user interfaces with the power of C# and a familiar component-based approach. One common requirement for most web applications is the need for a login page. In this article, I will walk you through an example of how to create a login page using Blazor.

Setting up the Blazor App

Before we dive into creating the login page, let’s first set up a new Blazor application. Open up your favorite code editor and run the following command in the terminal:

dotnet new blazorserver -n MyLoginApp

This will create a new Blazor Server App named “MyLoginApp”. Once the command finishes running, navigate into the newly created project folder:

cd MyLoginApp

Next, let’s run the application using the following command:

dotnet run

Now, open your favorite web browser and navigate to https://localhost:5001. You should see the default Blazor app running successfully.

Adding a Login Page

Now that we have our Blazor app set up, let’s go ahead and add a login page. In Blazor, we can create a new Razor component for our login page. Create a new file called LoginPage.razor under the Pages folder in your project:

Pages/LoginPage.razor

Open the LoginPage.razor file and replace the existing code with the following:


@page "/login"
@inject NavigationManager NavigationManager

Login

Welcome to the login page! Please enter your credentials:



@code {
private void Login()
{
// Add your login logic here
NavigationManager.NavigateTo("/dashboard");
}
}

In this code snippet, we define a new Blazor component for our login page. The @page directive specifies the URL at which this page will be accessible, in this case, “/login”. The @inject NavigationManager directive allows us to easily navigate to other pages within our application.

The HTML markup consists of a simple login form with fields for username and password, and a login button. The @onclick="Login" attribute triggers the Login method when the button is clicked. In this example, the Login method simply navigates to the “/dashboard” page, but you can replace this with your own login logic.

To test the login page, navigate to https://localhost:5001/login in your web browser. You should see the login form rendered.

Conclusion

Creating a login page using Blazor is straightforward and powerful. Blazor allows us to build interactive and dynamic web applications using C#, and with its component-based approach, we can easily create reusable UI components.

In this article, we walked through an example of creating a login page in a Blazor Server App. We set up the app, created a new Razor component for the login page, and added basic login form functionality.

Blazor is an exciting technology that is continuously evolving, and it offers a lot of possibilities for building modern web applications. I encourage you to explore further and experiment with Blazor to see how it can benefit your development workflow.
