NativeScript is an open source framework created by Telerik that makes native mobile app development easier for web developers. It enables developers to use JavaScript or TypeScript (with or without Angular or Vue) to build native mobile applications for iOS and Android. NativeScript apps render native UI components styled by a subset of CSS. Modules provide cross-platform native API abstractions. 100% of native APIs are available via JavaScript.

NativeScript is an open source (ASLv2) framework created by Progress for building truly native mobile apps with JavaScript, TypeScript, Angular or Vue. Use web skills and get native UI and performance on iOS and Android. The Angular developers can share code between Web and Mobile applications via the Code Sharing CLI.

NativeScript apps use native UI components. The framework provides a subset of CSS to make styling simple and familiar for web developers. Modules provide cross-platform API abstractions so that a single codebase can run on multiple platforms. The framework provides 0-day access to 100% of native APIs via JavaScript via build-time metadata generation.

As of March 2019, NativeScript is in version 5.3.0. See the NativeScript roadmap for information about prior and planned versions of NativeScript.

The source can be found at the NativeScript GitHub repository and issues are tracked on the NativeScript GitHub issue tracker.
