Learning TypeScript 2.x - Second Edition

By: Remo H. Jansen

Overview of this book

TypeScript is an open source and cross-platform statically typed superset of JavaScript that compiles to plain JavaScript and runs in any browser or host. This book is a step-by-step guide that will take you through the use and benefits of TypeScript with the help of practical examples. You will start off by understanding the basics as well as the new features of TypeScript 2.x. Then, you will learn how to work with functions and asynchronous programming APIs. You will continue by learning how to resolve runtime issues and how to implement TypeScript applications using the Object-oriented programming (OOP) and functional programming (FP) paradigms. Later, you will automate your development workflow with the help of tools such as Webpack. Towards the end of this book, you will delve into some real-world scenarios by implementing some full-stack TypeScript applications with Node.js, React and Angular as well as how to optimize and test them. Finally, you will be introduced to the internal APIs of the TypeScript compiler, and you will learn how to create custom code analysis tools.

Webpack development server

The Webpack development server is a command-line utility that monitors our filesystem for changes and triggers the Webpack bundling process.

We can install the Webpack development server using npm:

    npm install -g webpack-dev-server  

We can then execute the webpack development server using the following command:

    webpack-dev-server  

The Webpack development server will then start watching our filesystem for changes. If a change is detected, it will automatically run the Webpack build process using the existing the webpack.config.js file.

The Webpack development server also starts a web server. The server is running on port 8080 by default.

Please refer to the documentation at https://github.com/webpack/webpack-dev-server to learn more about the Webpack development server.
