Overview of this book

The TypeScript language, compiler, and open source development toolset brings JavaScript development up to the enterprise level. It allows you to use ES5, ES6, and ES7 JavaScript language features today, including classes, interfaces, generics, modules, and more. Its simple typing syntax enables building large, robust applications using object-oriented techniques and industry-standard design principles. This book aims at teaching you how to get up and running with TypeScript development in the most practical way possible. Taking you through two exciting projects built from scratch, you will learn the basics of TypeScript, before progressing to functions, generics, promises, and callbacks. Then, you’ll get to implement object-oriented programming as well as optimize your applications with effective memory management. You’ll also learn to test and secure your applications, before deploying them. Starting with a basic SPA built using Angular, you will progress on to building, maybe, a Chat application or a cool application. You’ll also learn how to use NativeScript to build a cool mobile application. Each of these applications with be explained in detail, allowing you to grasp the concepts fast. By the end of this book, you will have not only built two amazing projects but you will also have the skills necessary to take your development to the next level.

The application so far

We now have a basic version of our Trello application with the Homepage component and the Trello service integrated. So, now let's run our application and see the result.

As we saw in an earlier section, the NativeScript CLI provides us with the run command to build and execute the code and deploy it on the selected platform. We can execute the run command without specifying the platform, which will result in NativeScript running the application on all the connected devices. So, if you have iOS and Android devices connected, NativeScript will deploy the application on both and execute them.

We can configure a specific platform when executing the run command as well, and even mention a specific device ID on which we want NativeScript to install the code.
