NativeScript and Angular 4
NativeScript is an open-source framework to develop apps on the Apple iOS and Android platforms. It was originally conceived and developed by Progress. NativeScript apps are built using JavaScript, or by using any language that transpiles to JavaScript, such as TypeScript. NativeScript directly supports the Angular framework and supports the Vue framework via a community-developed plugin. Mobile applications built with NativeScript result in fully native apps, which use the same APIs as if they were developed in Xcode or Android Studio. Additionally, software developers can re-purpose third-party libraries from Cocoapods, Android Arsenal, Maven, and npm.js in their mobile applications without the need for wrappers.
NativeScript was publicly released first in March 2015. Version 1.0.0 followed two months later. The framework quickly gained popularity reaching 3000 github-stars and over 1500 followers on Twitter soon after the public release. In the meantime, over 700 plugins are available, which are either officially supported by Progress or stem from the open source community. The use of Angular is an optional development approach allowing for application source code to be shared between the web platform and mobile platform.
Structure
It is installed using the package manager npm. Projects are created, configured, and compiled via the command line or a GUI tool called NativeScript Sidekick. Platform-independent user interfaces are defined using XML files. It then uses the abstractions described in the XML files to call native UI elements of each platform. Application logic developed in Angular and TypeScript can be developed independent of the target platform as well. A NativeScript mobile application is built using the node.js runtime and tooling. Progress aims for a ratio of 90% common code between the iOS and Android platforms.
