Hands-On TypeScript for C# and .NET Core Developers: Transition from C# to TypeScript 3.1 and build applications with ASP.NET Core 2

Discover how TypeScript allows you to build modern client-rich applications, thanks to its object-oriented capabilities and third-party tools like Angular and Web APIs

Key Features

• Make a seamless transition to using TypeScript 3.1 in your development stack
• Work with TypeScript 3.1 in your ASP.NET Core projects to build rich applications that are easy to maintain
• Build, test, and integrate your own TypeScript library in real-world projects

Book Description

Writing clean, object-oriented code in JavaScript gets trickier and complex as the size of the project grows. This is where Typescript comes into the picture; it lets you write pure object-oriented code with ease, giving it the upper hand over JavaScript. This book introduces you to basic TypeScript concepts by gradually modifying standard JavaScript code, which makes learning TypeScript easy for C# ASP.NET developers.

As you progress through the chapters, you'll cover object programming concepts, such as classes, interfaces, and generics, and understand how they are related to, and similar in, both ES6 and C#. You will also learn how to use bundlers like WebPack to package your code and other resources. The book explains all concepts using practical examples of ASP.NET Core projects, and reusable TypeScript libraries. Finally, you'll explore the features that TypeScript inherits from either ES6 or C#, or both of them, such as Symbols, Iterables, Promises, and Decorators.

By the end of the book, you'll be able to apply all TypeScript concepts to understand the Angular framework better, and you'll have become comfortable with the way in which modules, components, and services are defined and used in Angular. You'll also have gained a good understanding of all the features included in the Angular/ASP.NET Core Visual Studio project template.

What you will learn

• Organize, test, and package large TypeScript code base
• Add TypeScript to projects using TypeScript declaration files
• Perform DOM manipulation with TypeScript
• Develop Angular projects with the Visual Studio Angular project template
• Define and use inheritance, abstract classes, and methods
• Leverage TypeScript-type compatibility rules
• Use WebPack to bundle JavaScript and other resources such as CSS to improve performance
• Build custom directives and attributes, and learn about animations
