One Blazor Template to Rule Them All in .NET 8

In .NET 8 there is a new project in town that unifies the developing experience between Blazor Server and Blazor Web Assembly application models. In this video we will go over the new template and how we can get started using it! 

Once created, these custom elements -- a custom counter, for example -- can also be used in other single-page application (SPA) web frameworks such as React and Angular. A sample project, aptly titled Blazor Custom Elements, shows how to do just that, providing examples about how to work with those frameworks and the client-side Blazor WebAssembly component as well as Blazor Server.  

This books shows all the steps necessary for the development of SPA (Single Page Application) applications with the Aurelia. With this book you will learn:

• How to create a project in Aurelia
• How to create Aurelia plugin
• Understand how the SystemJS imports works
• Using HTTP to connect to a server
• HttpClient
• FetchClient
• How to use Firebase
• Offline the app data
• Working with loopback
• ...
