Blazor WebAssembly by Example

By: Toi B. Wright

Overview of this book

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#.

Technical requirements

To complete this project, you need to have Visual Studio 2019 installed on your PC. For instructions on how to install the free Community Edition of Visual Studio 2019, refer to Chapter 1, Introduction to Blazor WebAssembly. You will also need the Empty Blazor WebAssembly App project template that we created in Chapter 2, Building Your First Blazor WebAssembly Application.

We will be using an external weather API to access the weather forecast data for our project. The API that we will be using is the OpenWeather One Call API for getting current, forecasted, and historical weather data. This is a free API that is provided by OpenWeather (https://openweathermap.org). In order to get started with this API, you need to create an account and obtain an API key. If you do not want to create an account, you can use the weather.json file that we have provided in the GitHub repository for this chapter.
