Overview of this book

By learning TypeScript, you can start writing cleaner, more readable code that’s easier to understand and less likely to contain bugs. What’s not to like? It’s certainly an appealing prospect, but learning a new language can be challenging, and it’s not always easy to know where to begin. This book is the perfect place to start. It provides the ideal platform for JavaScript programmers to practice writing eloquent, productive TypeScript code. Unlike many theory-heavy books, The TypeScript Workshop balances clear explanations with opportunities for hands-on practice. You’ll quickly be up and running building functional websites, without having to wade through pages and pages of history and dull, dry fluff. Guided exercises clearly demonstrate how key concepts are used in the real world, and each chapter is rounded off with an activity that challenges you to apply your new knowledge in the context of a realistic scenario. Whether you’re a hobbyist eager to get cracking on your next project, or a professional developer looking to unlock your next promotion, pick up a copy and make a start! Whatever your motivation, by the end of this book, you’ll have the confidence and understanding to make it happen with TypeScript.

Overview

This chapter introduces you to Dependency Injection (DI) in TypeScript. It demonstrates how to implement the DI design pattern. You will also see some common use cases for the DI pattern, including ones from libraries such as Angular and Nest.js. This chapter will teach you how to build a simple Angular application that uses DI. You will also learn some basics of InversifyJS and how to use it in your TypeScript applications. By the end of this chapter, you will be able to build a calculator application that utilizes DI using InversifyJS.
