Getting Started with NativeScript

Overview of this book

NativeScript allows you to build a fast cross-platform application that has a native UI. NativeScript is a true cross-platform framework that generates native speed applications using the native components of the host platform, all using JavaScript. Although NativeScript allows you to build your application in JavaScript, you have full access to the host OS from your code, allowing you to easily tweak or use new platform features instantly at native code speeds. Whether you have already developed multiple applications or zero applications, this book will help you to develop your next application in a cross-platform framework quickly, saving you a massive amount of time and money. This book concisely shows you NativeScript’s built-in framework that allows you to rapidly develop a fully-working compiled cross-platform application in just a few chapters. It starts by laying the foundation of NativeScript and working through the fundamentals to create a basic shell of the application. Moving on, you’ll see how to build a full-fledged application step by step. We’ll show you how to use plugins, and how to communicate with the native OS libraries easily so that you can customize your application as if your app was created in Java or Objective C. We then deal with the issues that arise from being cross platform and compensate for the different screen sizes, screen resolutions, and device abilities. Finally, we progress to testing and deploying your app.

Using third-party components

Once we have all the plugins installed, the next step is to actually use each of the plugins. We will need to open your main-page.js file and add some code to use the plugin inside your application's main page.

Using the vibration plugin

We will start with this cool feature first. We want to make the device vibrate when a new message comes in. First, we just need to add the code to load the vibration component. Open the main-page.js file. At the top of the file near the other required statements, you need to add a simple new require statement, var vibrate = require('nativescript-vibrate');. Since all the messages already go through a central newMessage function, let's add this code at the very bottom of this function:

if (msg.from !== 1) {

This code simply checks to see that the message doesn't come from us. After all, we don't really want to make the phone vibrate on our own messages. It then uses the vibrate class that we required a...
