Overview of this book

TypeScript is a superset of the JavaScript programming language, giving developers a tool to help them write faster, cleaner JavaScript. With the help of its powerful static type system and other powerful tools and techniques it allows developers to write modern JavaScript applications. This book is a practical guide to learn the TypeScript programming language. It covers from the very basics to the more advanced concepts, while explaining many design patterns, techniques, frameworks, libraries and tools along the way. You will also learn a ton about modern web frameworks like Angular, Vue.js and React, and you will build cool web applications using those. This book also covers modern front-end development tooling such as Node.js, npm, yarn, Webpack, Parcel, Jest, and many others. Throughout the book, you will also discover and make use of the most recent additions of the language introduced by TypeScript 3 such as new types enforcing explicit checks, flexible and scalable ways of project structuring, and many more breaking changes. By the end of this book, you will be ready to use TypeScript in your own projects and will also have a concrete view of the current frontend software development landscape.

Bonus – creating a new project using the Vue CLI

We've used the Vue CLI to create an example application with TypeScript support enabled. You can find it in the code samples for this book, under Chapter09/04-vue-cli/01-empty.

When you use the Vue CLI to create an application, it asks a series of questions that let you customize the project creation process.

Here's how we created our example application and the options that we used:

  • Command: vue create 01-empty
  • Manually select features
  • Package manager? Yarn
  • Features:
  • TypeScript
  • Linter/Format
  • Unit testing
  • E2E testing

At the second stage, the CLI has asked us the following questions:

  • Use class-style component syntax? Yes
  • Which linter to use? TSLint
  • When to lint? Lint on save
  • Which library for unit tests? Jest
  • Which library to use for E2E tests? Cypress
  • Where to store configurations? In dedicated config files
