What is NativeScript
To learn more about NativeScript, you can check the following resources:
- The NativeScript web page
- NativeScript - a Technical Overview
- Announcing NativeScript - cross-platform framework for building native mobile applications
- The NativeScript Documentation repo and Documentation portal
- The NativeScript FAQ
How the NativeScript CLI works
The NativeScript CLI is the command-line interface for interacting with NativeScript. It incorporates several important services. Consider the following diagram:
- Commands - pretty much what every CLI does - support of different command options, input validation and help
- Devices Service - provides the communication between NativeScript and devices/emulators/simulators used to run/debug the app. Uses iTunes to talk to iOS and adb for Android
- LiveSync Service - redeploys applications when code changes during development
- Hooks Service - executes custom-written hooks in developed application, thus modifying the build process
- Platforms Service - provides app build functionalities, uses Gradle to build Android packages and Xcode for iOS.
With the NativeScript CLI, you can target the following mobile platforms.
- Android 4.2 or a later stable official release
- iOS 9.0 or later stable official release
You can install and run the NativeScript CLI on Windows, macOS or Linux.
Install the NativeScript CLI
The NativeScript CLI is available for installing as an npm package.
In the command prompt, run the following command.
|OS||Node.js installed from http://nodejs.org/||Node.js installed via package manager|
To check if your system is configured properly, run the following command.
Configure Proxy Settings
If you are working with the NativeScript CLI behind a web proxy, you need to configure your proxy settings.
Set Proxy Settings
tns proxy set <Url> <Username> <Password>
(Required) The full URL of the proxy. The
<Url>attribute is required and if you do not provide it when running the command, the NativeScript CLI will prompt you to provide it. An example of a valid proxy URL is
(Optional) The credentials for the proxy. The
<Password>attributes are optional, however, if you choose to provide them, you must provide both.
--insecureflag allows you to perform insecure SSL connections and transfers. This option is useful when your proxy does not have a CA certificate or the certificate is no longer valid.
- You can provide the
<Password>attributes only on Windows systems.
- Proxy settings for the npm, the Android Gradle and (optional) Docker need to be configured separately. For more information, see the following articles:
Display Current Proxy Settings
Clear Proxy Settings
tns proxy clear
tns help to view all available commands in the browser. Run
tns help <Command> to view more information about a selected command in the browser.
tns --help opens console help, where help information is shown in the console.
tns create MyApp --js
To create a new cross-platform project from the default TypeScript, Angular or Vue template, use the
template option followed by either
tns create MyApp --template typescripttns create MyApp --template angulartns create MyApp --template vue
Or you can simply use the shorthand
tns create MyApp --tsctns create MyApp --ng
template option you can also specify a local or a remote path to the template that you want to use to create your project.
For example, if you want to create a React template, run the following command.
tns create MyApp --template
The NativeScript CLI creates a new project and sets the application identifier to
The CLI places the project in a new directory in the current directory. The newly created directory has the following structure.
MyApp/ ├── app │ ├── App_Resources │ └── ... └── platforms └── ...
appdirectory is the development space for your application. You should modify all common and platform-specific code within this directory. When you run
prepare <Platform>, the NativeScript CLI prepares relevant content to the platform-specific folders for each target platform.
platformsdirectory is created empty. When you add a target platform to your project, the NativeScript CLI creates a new subdirectory with the platform name. The subdirectory contains the ready-to-build resources of your app. When you run
prepare <Platform>, the NativeScript CLI prepares relevant content from the
appdirectory to the platform-specific subdirectory for each target platform.
Develop Your Project
Development with NativeScript
For more information about working with NativeScript, see the following resources.
app directory in the root of the project is the development space for your project. Place all your common and platform-specific code in this directory.
app directory, you can use platform-specific files to provide customized functionality and design for each target platform. To indicate that a file is platform-specific, make sure that the file name is in the following format:
name.android.extension. For example:
You can develop shared functionality or design in common files. To indicate that a file is common, make sure that the file name does not contain a
IMPORTANT: Avoid editing files located in the
platformssubdirectory because the NativeScript CLI overrides such files.
Modifying Configuration Files
The NativeScript CLI respects any platform configuration files placed inside
Modifying Entitlements File (iOS only)
To specify which Capabilities are required by your App - Maps, Push Notifications, Wallet and etc. you can add or edit the
app.entitlements file placed inside
app/App_Resources/iOS. When building the project, the default
app/App_Resources/iOS/app.entitlements file gets merged with all Plugins entitlement files and a new
yourAppName.entitlements is created in the platforms directory. The path would be
app/platforms/ios/<application name>/<application name>.entitlements and will be linked in the
You can always override the generated entitlements file, by pointing to your own entitlements file by setting the
CODE_SIGN_ENTITLEMENTS property in the
Build Your Project
You can build it for your target mobile platforms.
tns build androidtns build ios
The NativeScript CLI calls the SDK for the selected target platform and uses it to build your app locally.
When you build for iOS, the NativeScript CLI will either build for a device, if there's a device attached, or for the native emulator if there are no devices attached. To trigger a native emulator build when a device is attached, set the
IMPORTANT: To build your app for an iOS device, you must configure a valid certificate and provisioning profile pair, and have that pair present on your system for code signing your application package. For more information, see iOS Code Signing - A Complete Walkthrough.
Run Your Project
You can test your work in progress on connected Android or iOS devices.
To verify that the NativeScript CLI recognizes your connected devices, run the following command.
The NativeScript CLI lists all connected physical devices and running emulators/simulators.
After you have listed the available devices, you can quickly run your app on connected devices by executing:
tns run androidtns run ios
Extending the CLI
The NativeScript CLI lets you extend its behavior and customize it to fit your needs by using hooks.
When you run one of the extendable commands (for example,
tns build), the CLI checks for hooks and executes them. Plugins can also use hooks to control the compilation of the application package.
For more information, see the Extending the CLI document
If the NativeScript CLI does not behave as expected, you might be facing a configuration issue. For example, a missing
JAVA path. To check if your system is configured properly for the NativeScript CLI, run the following command.
This command prints warnings about current configuration issues and provides basic information about how to resolve them.

How to Build
git clone https://github.com/NativeScript/nativescript-cli cd nativescript-cli npm run setup
To use the locally built CLI instead
tns you can call
PATH_TO_CLI_FOLDER/bin/tns. For example:
PATH_TO_CLI_FOLDER/bin/tns run ios|android
