Blazor WebAssembly by Example

Chapter 2: Building Your First Blazor WebAssembly Application

Razor components are the building blocks of Blazor WebAssembly applications. A Razor component is a chunk of user interface that can be shared, nested, and reused. Razor components are ordinary C# classes and can be placed anywhere in a project.

In this chapter, we will learn about Razor components. We will learn how to use them, how to apply parameters, and about their life cycle and their structure. We will learn how to use the @page directive to define routing. We will also learn how to use Razor syntax to combine C# code with HTML markup.

The Blazor WebAssembly project in this chapter will be created by using the Blazor WebAssembly App project template provided by Microsoft. After we create the project, we will examine it to further familiarize ourselves with Razor components. We will learn how to use components, how to add parameters, how to apply routing, how to use Razor syntax, and how to separate the Razor markup and code into separate files. Finally, we will configure our own custom project template that creates an empty Blazor WebAssembly project.

In this chapter, we will cover the following topics:

  • Razor components
  • Routing
  • Razor syntax
  • Using the Blazor App project template
  • Creating an empty Blazor WebAssembly project template

Key benefits

  • Explore complete, easy-to-follow web projects using Blazor
  • Build projects such as a weather app, expense tracker, and Kanban board with real-world applications
  • Understand and work with Blazor WebAssembly effectively without spending too much time focusing on the theory

Description

Blazor WebAssembly makes it possible to run C# code on the browser instead of having to use JavaScript, and does not rely on plugins or add-ons. The only technical requirement for using Blazor WebAssembly is a browser that supports WebAssembly, which, as of today, all modern browsers do. Blazor WebAssembly by Example is a project-based guide for learning how to build single-page web applications using the Blazor WebAssembly framework. This book emphasizes the practical over the theoretical by providing detailed step-by-step instructions for each project. You'll start by building simple standalone web applications and progress to developing more advanced hosted web applications with SQL Server backends. Each project covers a different aspect of the Blazor WebAssembly ecosystem, such as Razor components, JavaScript interop, event handling, application state, and dependency injection. The book is designed in such a way that you can complete the projects in any order. By the end of this book, you will have experience building a wide variety of single-page web applications with .NET, Blazor WebAssembly, and C#.

Who is this book for?

This book is for .NET web developers who are tired of constantly learning new JavaScript frameworks and wish to write web applications using Blazor WebAssembly, leveraging the power of .NET and C#. The book assumes beginner-level knowledge of the C# language, .NET framework, Microsoft Visual Studio, and web development concepts.

What you will learn

  • Discover the power of the C# language for both server-side and client-side web development
  • Use the Blazor WebAssembly App project template to build your first Blazor WebAssembly application
  • Use templated components and the Razor class library to build and share a modal dialog box
  • Understand how to use JavaScript with Blazor WebAssembly
  • Build a progressive web app (PWA) to enable native app-like performance and speed
  • Understand dependency injection (DI) in .NET to build a shopping cart app
  • Get to grips with .NET Web APIs by building a task manager app

Packt never fails to impress with their content. Blazor WASM is an awesome new tool and this teaches you everything you need to know to make a well designed application. Like all Packt books, it is easy to pick up in different chapters depending on what you want to learn. I was specifically looking more into how to make a PWA with Blazor and this was a fantastic guide!

I appreciate the author’s “no fluff” approach to covering all the basics Blazor developers need to know. As someone who has developed a few Blazor applications already, this meant that I was able to finish the content in just a few sessions. Being somewhat experienced, I certainly did pick up some new information, but I think beginner-to-intermediate developers will get the most out of this book.Personally, I thought the use of project templates was very appropriate and I wish more Visual Studio developers made use of this gem of an IDE feature. The sections on RenderFragment, EventCallback, CSS isolation, attribute splatting, and JS Interop were explained nicely. Content on Progressive Web Apps contained details, like the service worker life cycle, that were good to learn more about.I was impressed at the author’s ability to present straightforward examples, each of which demonstrated a Blazor capability with minimal code. Sticking close to just what is needed made it easy to understand what was happening.Overall, I liked this book, which is clearly designed to be a quick overview of each topic. After covering the basics, the author provides “further reading” sections at the conclusion of each chapter to make it easy to go deeper, if desired. There are also sample questions along the way that help you gauge your knowledge or think about what could be next if you want to experiment with extending the project samples.

Blazor WebAssembly is the Microsoft's single-page application (SPA) framework for building web applications on .NET Framework. It is another option that front-end developers should have in mind. One of the main difference with their main competitors (Vue, React, Angular) is that it enables developers to run C# code on the client. It means, you can develop an entire SPA application without using JavaScript.Toi (the author of this book) teaches us how to use Blazor WebAssembly in a practical way. She provides a set of projects and examples which are very useful and which teaches us the fundamental elements of Blazor WebAssembly. For example, (i) you will implement a simple modal dialog application, which focuses on razor elements, components, and RenderFragments. (ii) You will implement a simple data storage application, which explains how to use JS Interop to execute some JavaScript commands from a Blazor WebAssembly application (there are some cases in which using JavaScript makes sense). (iii) You will implement a Weather App which uses service workers, APIs, and implementation of PWA applications. And (iv) even, it takes you to develop a complete front-end and back-end application (task manager) with the use of an ASP.NET Web API. Other topics and projects include: application state, events, edit forms, and dependency injection.All those projects (and many others) present proper explanations, with excellent examples. The code of the projects is easy to follow, simple, and properly detailed. Therefore, you can use some of those projects as a base to develop your own applications.This is a totally recommended book if you want to learn Blazor WebAssembly in a practical way, with very useful examples, and short explanations. Congratulations to the author.

I love reading through example-focused books, and Blazor by Example is no exception! As the title states, this is a project-based guide to building web apps with .NET, Blazor WebAssembly, and C#.On your journey through learning Blazor by Example, you'll create several applications that scale up in complexity by chapter. Everything from creating your first Blazor application and making a weather app PWA to handling application state in a shopping cart experience gets covered throughout the projects in the book.I highly recommend this book to anyone interested in Blazor. It's a great learning resource and reference for Blazor WebAssembly projects.Here are a few of my chapter/topic highlights:- JS Interop- Building a Progressive Web App (PWA)- Using Application State- Building a Kanban Board using Events- Building a Task Manager using ASP.NET Web API
