If you know the basics of C#, you're ready to learn how to create web applications using Microsoft's powerful technology, ASP.NET Core MVC (Model-View-Controller). And there's no more practical way to do it than with this book. By the end of section 1...just 5 chapters...you'll be developing real-world web apps that follow the MVC pattern, using C# code for the model and controller classes...HTML, CSS, and Razor code for the user interface (the view)...and Bootstrap classes for responsive design so that your apps adapt well to all screen sizes. You'll also be able use the debugging tools in Visual Studio and your browser to test your apps thoroughly. In section 2, you'll build out that set of skills to create more complex controllers, work with Razor views, handle cookies and sessions, do model binding, validate data, and handle database data with EF (Entity Framework) Core. You'll also see how all these skills come together in a single application, with coverage of the "gotchas" that can occur and how to solve them. Finally, in section 3, you can pick up additional skills as you need them: use dependency injection to make your code easier to test; automate testing; create custom tag helpers and view components to reduce code duplication; control user access to a site with ASP.NET Core Identity; and use Visual Studio Code, an increasingly popular alternative to the Visual Studio IDE. All along the way, you'll get complete web apps that show you how each feature works in context (you can download these apps for free from the Murach website). You'll get chapter exercises that let you practice your new skills. And you'll get Murach's distinctive "paired-pages" format that presents each skill in a 2-page spread, full of examples, notes, and explanation...a format that developers praise because it saves training and reference time.

The topics here are not deep dive and the book is intended for busy .NET developers who have limited time and want a quick implementation of a clean architecture with popular libraries. You’ll start by setting up your web app’s backend, guided by clean architecture, command query responsibility segregation (CQRS), mediator pattern, and Entity Framework Core 5. The book then shows you how to build the frontend application using best practices, state management with Vuex, Vuetify UI component libraries, Vuelidate for input validations, lazy loading with Vue Router, and JWT authentication. Later, you’ll focus on testing and deployment. All the tutorials in this book support Windows 10, macOS, and Linux users. By the end of this book, you’ll be able to build an enterprise full-stack web app, use the most common npm packages for Vue.js and NuGet packages for ASP.NET Core, and deploy Vue.js and ASP.NET Core to Azure App Service using GitHub Actions.

Explore what React, Node, TypeScript, Webpack, and Docker have to offer individually, and how they all fit together in modern app development. React is one of the most popular web development tools available today, and Node.js is extremely popular for server-side development. The fact that both utilize JavaScript is a big selling point, but as developers use the language more, they begin to recognize the shortcomings, and that’s where TypeScript comes in and why it’s gaining in popularity quickly. Add Webpack and Docker to the mix, and you’ve got a potent full development stack on which to build applications. You’ll begin by building a solid foundation of knowledge and quickly expand it by constructing two different real-world apps. These aren’t just simple, contrived examples but real apps that you can choose to install on your servers and use for real. By the end, you will have a solid grasp of building apps with React, Node.js, and TypeScript and a good grasp on how Webpack can be used to optimize and organize your code for deployment. You’ll also understand how Docker can be used to run the apps you build in a clear and well-defined way, all of which will be able to springboard you into creating more advanced apps on your own. What You'll Learn Get a project started and logically structure it Construct a user interface with React and Material-UI Use WebSockets for real-time communication between client and server Build a REST API with Node and Express as another approach to client-server communication Package the app with Webpack for optimized delivery Take a completed app and wrap it up with Docker for easy distribution Review a host of other ancillary topics including NPM, Semantic versioning, Babel, NoSQL, and more Who This Book Is For Webdevelopers with basic knowledge of HTML, JavaScript, CSS, and CLI tools who are interested in and in all aspects of application development, and using TypeScript instead of straight JavaScript.
