Why should I use Blazor for Web Development

Introduction:

Benefits of Using Blazor:

Single Language for Frontend and Backend:

Blazor Server:

Shared Language

Code Reusability

// Shared C# method in a service class
public class SharedService
{
   public string GetGreeting()
   {
       return "Hello, World!";
   }
}

@inject SharedService sharedService

<h1>@sharedService.GetGreeting()</h1>

Managing Data Consistency

// C# data model
public class User
{
   public int Id { get; set; }
   public string Name { get; set; }
   // Other properties...
}

@code {
   private User currentUser = new User { Id = 1, Name = "John Doe" };
}

<h2>Welcome, @currentUser.Name!</h2>

Blazor Web Assembly:

Shared Language

Code Reusability

public static class SharedUtility
{
   public static string GetMessage()
   {
       return "Hello, World! From WebAssembly";
   }
}

@code {
   private string message = SharedUtility.GetMessage();
}

<h1>@message</h1>

Managing Data Consistency

// Shared C# data model
public class Product
{
   public int Id { get; set; }
   public string Name { get; set; }

   // Other properties...

@code {
   private Product currentProduct = new Product { Id = 1, Name = "Blazor Awesome" };
}

<h2>Current Product: @currentProduct.Name</h2>

Full Stack .NET Development:

Blazor Server:

Unified Ecosystem

@using System.Net.Http // Importing a .NET namespace

@code {
   private string serverResponse;

   private async Task FetchData()
   {
       using var client = new HttpClient();
       serverResponse = await client.GetStringAsync("https://api.example.com/data");
   }
}

<button @onclick="FetchData">Fetch Data</button>
<p>@serverResponse</p>

Database Integration

// Example of a Blazor Server service using Entity Framework Core

public class DataService
{
   private readonly ApplicationDbContext _context;

   public DataService(ApplicationDbContext context)
   {
       _context = context;
   }

   public async Task<List<Item>> GetItems()
   {
       return await _context.Items.ToListAsync();
   }
}

Blazor Web Assembly:

Unified .NET Ecosystem

@code {
   private string serializedData;
   private void SerializeObject()
   {
       var data = new { Name = "John", Age = 30 };
       serializedData = System.Text.Json.JsonSerializer.Serialize(data);
   }
}
<button @onclick="SerializeObject">Serialize Data</button>

<p>@serializedData</p>

Database Integration

@inject HttpClient httpClient

@code {

   private string serverResponse;

   private async Task FetchData()
   {
       serverResponse = await httpClient.GetStringAsync("https://api.example.com/data");
   }
}
<button @onclick="FetchData">Fetch Data</button>

<p>@serverResponse</p>

Component-Based Architecture:

Blazor Server:

Component-Based Structure

<!-- Example of a Blazor Server component -->
<h3>GreetingsComponent</h3>

<p>@Message</p>

@code {
   [Parameter]
   public string Message { get; set; }
}

<GreetingsComponent Message="Hello, World!" />

Component Composition

<!-- Example of a composed Blazor Server component -->
<h2>WelcomeComponent</h2>

<div>
   <GreetingsComponent Message="Hello, Blazor!" />
</div>

Here, the WelcomeComponent includes the GreetingsComponent within it, showcasing how smaller components can be composed to create more complex and reusable structures.

Blazor Web Assembly:

Component-Based Structure

<!-- Example of a Blazor WebAssembly component -->

<button @onclick="OnClick">@ButtonText</button>

@code {

   [Parameter]

   public string ButtonText { get; set; }

   [Parameter]

   public EventCallback OnClick { get; set; }

}

<ButtonComponent ButtonText="Click me!" OnClick="@HandleClick" />

@code {

   private async Task HandleClick()
   {
       // Handle click logic
   }
}

Component Composition

<!-- Example of composed Blazor WebAssembly component -->
<LayoutComponent>

   <HeaderComponent />

   <MainContentComponent />

   <FooterComponent />

</LayoutComponent>

High Performance:

Blazor Server:

Efficient Rendering

Real-time Updates

Example:

@code {
   private List<Item> items;

   protected override async Task OnInitializedAsync()
   {
       items = await ItemService.GetItemsAsync(); // Fetch items from the server
   }
}

Blazor Web Assembly:

Near-Native Performance

Offline Capabilities

@code {

   private List<Item> items;
​
   protected override async Task OnInitializedAsync()
   {
       var response = await httpClient.GetAsync("https://api.example.com/items");

       if (response.IsSuccessStatusCode)
       {
           items = await response.Content.ReadFromJsonAsync<List<Item>>();
       }
   }
}

Security and Type-Safety:

Blazor Server:

Server-Side Execution

Type-Safety

@code {

   private int count;

   private void IncrementCount()
   {
       count++; // Type-safe operation, ensuring count remains an integer
   }
}

Blazor Web Assembly:

Client-Side Sandboxing

Type-Safety

@code {

   private int count;

   private void IncrementCount()
   {
       count++; // Type-safe operation, preserving the integrity of count as an integer
   }
}
