Blazor Tutorial – How to Create Web Applications Using the Blazor Framework


If you want to learn how to create web applications using the Blazor framework, you’ve come to the right place. This tutorial will introduce you to the framework, describe Razor components, and explain how to use server-side prerendering and gRPC. By the end of this article, you’ll know how to create a working Blazor application in a day.

Introduces the Blazor framework

In this article, I’ll introduce the Blazor framework, a new web framework inspired by React, Vue, Angular, and Razor Pages. Blazor is a modular framework that uses components to build web applications. These components can be C# classes or Razor markup pages.

The Blazor framework uses Razor for creating dynamic HTML. Razor components are self-contained units of markup, which can be nested and reused across projects. Using Blazor, you can easily inject and use these components in your projects. The framework also includes built-in and custom services.

While Blazor has some advantages over JavaScript, it’s not a substitute. The separation of the app/component model and renderer allows it to create native mobile and web technology UIs. If you’re building a web application with Blazor, you can use either the Blazor Server hosting model or the Blazor WebAssembly security model to secure it.

Introduces Razor components

This article introduces Razor components and discusses their use in MVC and Razor Pages. Razor Components are built with a unique architecture that allows the user interface to run out-of-process in a remote browser. This will enable developers to write web applications without relying on JavaScript.

Components in the DOM can take values passed to them by callers. The Pager component, for instance, allows callers to pass the current page number, the total number of records, and the number of records per page. It also supports 2-way binding and UI Events. The two-way binding feature allows you to control data flow in and out of a component’s child components.

Razor components are designed to make front-end web development more straightforward. They combine the power of C# and HTML in an easy-to-use, modular way. They are also testable, shareable, and reusable. Razor components can be built with Microsoft’s Visual Studio, one of the most popular and powerful IDEs.

Explains server-side prerendering

This Blazor tutorial will help you understand how to use server-side prerendering. Prerendering is an effective way to speed up your web app. However, this method requires you to maintain App dependencies in client and server projects. In addition, this solution prevents your Blazor WASM Apps from being served by a CDN.

Prerendering is useful when you need to display data that frequently changes, such as a Twitter or Facebook feed. However, this can cause problems for some applications. Typically, the problem is in the configuration of the server-side application. For example, if the server-side app has a different HttpClient, it may not be able to prerender properly. This will cause the UI not to be responsive.

Server-side prerendering in Blazor uses an asynchronous process to execute code that will eventually run on the client side. First, the Blazor runtime checks the DOM for routable components, and if the counter component matches the link, it creates it and executes its lifecycle methods. This process also determines how many changes are needed to update the DOM. Once this is completed, the JavaScript runtime applies the changes to the physical DOM. The UI then updates as the user navigates the Counter page.

Explains gRPC

gRPC is a protocol for server-to-server communications. It’s used extensively in server-to-server applications but is now also supported in browser-to-server communications. It’s a widely used protocol and is available on GitHub. This Blazor tutorial will walk you through gRPC’s basics and show how you can use it in your application.

To use gRPC in your app, first, you need to create an Entity Framework Core project in Visual Studio 2019. After you’ve completed the project, create a new project called Blazor_Client. This project will have a Pages folder that contains default components and a Shared folder containing razor files.

gRPC aims to improve the performance of web applications by reducing network traffic. It uses a binary format that enables data to be transmitted in a compressed form. This significantly improves performance.

Shows how to build a simple quiz application with Blazor

The Blazor framework is a browser-based programming language that lets you create a full-stack web application with a C# back end. For example, you can build a quiz application that shows multiple answers and assigns scores based on the responses entered. This course teaches you how to make a quiz application using the Blazor Server hosting model. You can also secure your application using Blazor WebAssembly.

You can use Visual Studio to create your Blazor project. Alternatively, you can make the application by using the command line. You can view the source code in the GitHub repository regardless of your chosen method.
