Key Features

• Leverage the power of TypeScript for developing large-scale Angular apps;
• Take advantage of the cutting edge features of TypeScript 2.x for building high performing, maintainable applications;
• Explore TypeScript implementation of modules, classes, and annotations with Angular components

Book Description

TypeScript is the default language for building Angular applications from Google. TypeScript 2.0 adds optional static types, classes, and modules to JavaScript, to enable great tooling and better structuring of large JavaScript applications.

This book will teach you how to leverage the exciting features of TypeScript while working on Angular projects to build scalable, data intensive web applications. You will begin with setting up and installing Typescript followed by compiling it with JavaScript. You will then learn to write simple JavaScript expressions with Typescript. You will then go through some built in TypeScript types and accessors. Further you will build web components using TypeScript Interfaces and Decorators. You will go through the Angular form module which will enable you to write predicatable typed forms with Typescript and learn to use typed DOM events. You will also build a single page application using the Router Module. Lastly, you will go through the final building block by consuming API data with Angular's HTTP Module and handle responses with RxJS Observables. At the end of the book, you will go through different testing and debugging techniques.

What you will learn

• Move from loose types to predictable strict types
• Write self-documented API methods and data structures
• Understand Custom Generic Types for complex data structures
• Implement Contract with Interfaces
• Enhance Dependency Injection in Angular via Class Constructors
• Explore TypeScript Advanced Types
• Build Interactive Web Apps with Angular & TypeScript
