As everyone knows, there is a lot of code behind every great website. So, websites and coding are inseparable. When the number of codes on a website or application increases, the website speed will slow down. However, there is a powerful link between the website/application speed and visitors’ satisfaction level. That’s why you need to overcome such a problem. You may wonder, ‘How?’ This is where Blazor comes in. Today, we are going to answer ‘What is it?’ and introduce you to its features, hosting models, and prerequisites to use this framework. So, if you feel ready to learn this topic, let’s dive in!
What Exactly Is Blazor?
Blazor contains all the necessary features to work perfectly in modern browsers. Well, let’s take a quick look at its seven major features.
- You can run it on two different sides: on the server or in the browser (WebAssembly)
- It enables you to create an interactive and rich web application with C#.
- Since it is a part of ASP.NET Core, it can fastly and safely integrate with your existing applications.
- It was designed to work perfectly in all modern browsers, so you do not need a plugin.
- You build websites that drive more traffic to your web application.
- It helps you develop a lot of common development tasks, such as rendering HTML.
- Blazor has two major hosting models to run a web application. These are; Blazor Server and Blazor WebAssembly
Blazor Server (Server-side)
As its very name signifies, Blazor Server runs a web application on the Server. So, all the changes made on the client-side occur on the server-side through the SignalR connection. Then, the Server will handle the changes and update the client-side if needed.
Of course, Blazor Server has some advantages and disadvantages. Let’s take a look at the advantages, first.
- Blazor Server does not restrict old browser versions, so it allows you to adapt the application with non-new browsers.
- Since server-side applications pre-render the HTML content; they will load faster.
- Unlike WebAssembly, Blazor Server will not send your application code to the client, which will be more secure.
However, some disadvantages are inevitable while using Blazor Server.
- You need an ASP.NET Core server; otherwise, you will not be able to host your application.
- You need an active and consistent internet. However, if there is a problem with your internet connection, the application will not work. This is because it will continuously send data to the Server and from the Server.
- Blazor Server may cause a higher latency because of the continuous connection between the Server and the client if you get high traffic.
Blazor WebAssembly (Client-side)
WebAssembly, or also known as WASM, on the other hand, runs a web application completely in the browser. When a user opens a web application, all the code related to the client-side will be compiled, downloaded, and executed by the user’s browser.
There are several advantages to the Blazor WebAssembly hosting model. Let’s look at them quickly.
- Once the user downloads everything, there will no longer be a connection with the Server to generate new data.
- Using ASP.NET Core Web server to host your application is unnecessary. In other words, you can use any Web server.
- WebAssembly allows you to run an application offline on the client-server without a connection to the Server.
- If you want to reduce the load on the Server, WebAssembly helps you do it.
Since Blazor is open source; you can share your libraries and code between the server and the client whenever you wish.t
Despite many advantages, WebAssembly has some disadvantages as well.
- Your application will be limited to the capabilities of the browser.
- The application’s initial download may be time-consuming because it runs completely in the user’s browser.
- Since WebAssmebly only works on the latest browsers; you may face some compatibility issues.
- C# Knowledge: It is very important to learn about C# at an intermediate level when building your own application.
- ASP.NET Core Knowledge: Depending on the Blazor hosting model you will use, you need to learn about ASP.NET Core for web application development.
- Visual Studio: Since you may have difficulty setting up Blazor yourself, you can use Visual Studio. It will help you with both Blazor Server and Blazor WebAssembly applications.
