NativeScript provides platform APIs directly to the JavaScript runtime (with strong types) for a rich TypeScript development experience. As an open-source framework to develop apps for iOS, visionOS and Android platforms combining a best of all worlds approach marrying familiar Web approaches like CSS and view templating with common platform languages (Swift, Kotlin, Objective-C, Java) it delivers a liberating toolset for developers. It was originally conceived and developed by Bulgarian company Telerik, later acquired by Progress Software.{{Cite web|url=https://www.infoq.com/news/2015/03/nativescript/|title=Creating Mobile Native Apps in JavaScript with NativeScript|website=InfoQ|access-date=2022-07-12|archive-date=2022-06-19|archive-url=https://web.archive.org/web/20220619183512/https://www.infoq.com/news/2015/03/nativescript/|url-status=live}} At the end of 2019{{cite web |last1=Saripella |first1=Surya |title=The Next Chapter for NativeScript: nStudio |url=https://nativescript.org/blog/the-next-chapter-for-nativescript-nstudio/ |publisher=NativeScript |access-date=2022-07-12 |archive-date=2021-01-16 |archive-url=https://web.archive.org/web/20210116145010/https://nativescript.org/blog/the-next-chapter-for-nativescript-nstudio/ |url-status=live }} responsibility for the NativeScript project was taken over by long-time Progress partner, [https://nstudio.io nStudio].

Development

NativeScript was publicly released first in March 2015. Version 1.0.0 followed two months later.{{Cite web|url=https://www.i-programmer.info/news/167-javascript/8561-nativescript-100-released.html|title=NativeScript 1.0.0 Released|website=www.i-programmer.info|access-date=2022-07-12|archive-date=2022-06-11|archive-url=https://web.archive.org/web/20220611085454/https://www.i-programmer.info/news/167-javascript/8561-nativescript-100-released.html|url-status=live}} The framework quickly gained popularity reaching 3000 github-stars and over 1500 followers on Twitter soon after the public release.{{Cite web|url=https://www.nativescript.org/blog/nativescript-1.0.0-is-now-available|title=NativeScript 1.0.0 is now available|website=NativeScript.org|access-date=2016-11-04|archive-date=2016-10-05|archive-url=https://web.archive.org/web/20161005103930/https://www.nativescript.org/blog/nativescript-1.0.0-is-now-available|url-status=live}} In the meantime, over 700 plugins are available, which are either officially supported by Progress or stem from the open source community.{{Cite web|url=https://market.nativescript.org/|title=NativeScript Marketplace|website=market.nativescript.org|access-date=2018-03-14|archive-date=2018-03-15|archive-url=https://web.archive.org/web/20180315133334/https://market.nativescript.org/|url-status=live}}{{Cite web|url=https://www.npmjs.com/search?q=nativescript|title=nativescript - npm search|website=www.npmjs.com|access-date=2016-11-21|archive-date=2017-02-11|archive-url=https://web.archive.org/web/20170211155805/https://www.npmjs.com/search?q=nativescript|url-status=live}} The use of Angular is an optional development approach allowing for application source code to be shared between the web platform and mobile platform.{{Cite web|url=https://mobile.htmlgoodies.com/beyond/javascript/getting-to-know-angular-2.html|title=Getting to Know Angular 2|website=mobile.htmlgoodies.com|date=15 November 2016|access-date=12 July 2022|archive-date=27 September 2019|archive-url=https://web.archive.org/web/20190927013701/https://mobile.htmlgoodies.com/beyond/javascript/getting-to-know-angular-2.html|url-status=live}}

Structure

NativeScript and all the required plugins are installed using the package manager npm. Projects are created, configured, and compiled via the command line or a GUI tool called NativeScript Sidekick.{{Cite web|url=https://www.nativescript.org/nativescript-sidekick|title=NativeScript Sidekick - your faithful companion for app development|website=NativeScript.org|language=en|access-date=2017-10-31|archive-date=2017-11-07|archive-url=https://web.archive.org/web/20171107004639/https://www.nativescript.org/nativescript-sidekick|url-status=live}}

Platform-independent user interfaces are defined using XML files. NativeScript 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.{{Cite web|url=https://www.heise.de/developer/artikel/Mit-JavaScript-wie-hausgemacht-NativeScript-3282619.html|title=Mit JavaScript wie hausgemacht: NativeScript|first=Tam|last=Hanna|website=Developer|date=9 August 2016 |access-date=2022-07-12|archive-date=2021-07-25|archive-url=https://web.archive.org/web/20210725085644/https://www.heise.de/developer/artikel/Mit-JavaScript-wie-hausgemacht-NativeScript-3282619.html|url-status=live}} Progress aims for a ratio of 90% common code between the iOS and Android platforms.{{Cite web|url=https://www.nativescript.org/|title=Frequently asked questions about NativeScript|website=NativeScript.org|access-date=2016-03-20|archive-date=2016-03-18|archive-url=https://web.archive.org/web/20160318132229/https://www.nativescript.org/|url-status=live}}

Direct access to native platform APIs and controls

Platform-independent user interfaces are defined using XML files.{{Cite web|url=https://docs.nativescript.org/ui/basics|title=The Basics - NativeScript Docs|website=docs.nativescript.org|access-date=2016-11-21|archive-date=2016-11-21|archive-url=https://web.archive.org/web/20161121191907/http://docs.nativescript.org/ui/basics|url-status=live}} NativeScript uses the XML data structures representing the cross platform abstraction to trigger platform-specific code that directly interacts with the native elements of the target operating system. This means a call to the NativeScript Button API provides a UI abstraction for Button, which directly calls UIButton on iOS{{Cite web|url=https://github.com/NativeScript/NativeScript/blob/master/packages/core/ui/button/index.ios.ts|title=NativeScript/NativeScript|website=github.com|access-date=2022-06-20|archive-date=2022-06-20|archive-url=https://web.archive.org/web/20220620103533/https://github.com/NativeScript/NativeScript/blob/master/packages/core/ui/button/index.ios.ts|url-status=live}} or com.android.widget.Button on Android.{{Cite web|url=https://github.com/NativeScript/NativeScript/blob/master/packages/core/ui/button/index.android.ts|title=NativeScript/NativeScript|website=github.com|access-date=2022-06-20|archive-date=2022-06-20|archive-url=https://web.archive.org/web/20220620105953/https://github.com/NativeScript/NativeScript/blob/master/packages/core/ui/button/index.android.ts|url-status=live}}

While application source code is written in JavaScript, TypeScript, Angular, or Vue.js, the source code is not compiled or otherwise mutated. The source code as-is runs directly on the device. This architectural choice eliminates the need for cross-compiling or transpiling. Additionally, while the application source code is written in languages commonly encountered in a browser (or in a WebView-contained mobile application) NativeScript applications run directly on the native device. There is no DOM manipulation or any mandatory browser interaction.

Notable features

= Native API reflection =

Another notable feature is the use of reflection to handle native API endpoints. Rather than requiring separate binding layers between NativeScript and each mobile platform API, NativeScript uses reflection to gain information and metadata about the native platform APIs. New features added to any native platform API are available immediately.

Another way the reflection feature is used is in working with third party libraries. As JavaScript (or TypeScript/Angular) can talk directly to native code, there is no need to write binding layers in Objective-C, Swift, Java or Kotlin.{{Cite web|url=https://docs.nativescript.org/core-concepts/accessing-native-apis-with-javascript|title=Accessing Native APIs through JavaScript - NativeScript Docs|website=docs.nativescript.org|access-date=2016-11-21|archive-date=2016-11-24|archive-url=https://web.archive.org/web/20161124062717/http://docs.nativescript.org/core-concepts/accessing-native-apis-with-javascript|url-status=live}}

= Angular integration =

With the launch of NativeScript 2.0, it is possible to use Angular to build cross-platform mobile applications.{{Cite web|url=https://www.nativescript.org/blog/nativescript-2.0---the-best-way-to-build-cross-platform-native-mobile-apps|title=NativeScript 2.0 - the best way to build cross-platform native mobile apps|website=NativeScript.org|access-date=2016-11-21|archive-date=2016-12-20|archive-url=https://web.archive.org/web/20161220190523/https://www.nativescript.org/blog/nativescript-2.0---the-best-way-to-build-cross-platform-native-mobile-apps|url-status=live}} Additionally, when using Angular with NativeScript you have the ability to share large chunks of code between your web and mobile apps.{{Cite web|last=Witalec|first=Sebastian|date=2018-08-24|title=Apps That Work Natively on the Web and Mobile|url=https://blog.angular.io/apps-that-work-natively-on-the-web-and-mobile-9b26852495e7|access-date=2021-08-06|website=Medium|language=en|archive-date=2022-01-03|archive-url=https://web.archive.org/web/20220103100654/https://blog.angular.io/apps-that-work-natively-on-the-web-and-mobile-9b26852495e7|url-status=live}}

= Vue.js integration =

The Vue.js framework is supported in NativeScript via the nativescript-vue plugin.
