NativeScript Plugin for Nx

Requires at least NativeScript CLI v8.x.x or higher. You can confirm your CLI version by running ns --version.

Getting started

Prior to executing any commands, ensure that the node package manager you're going to use is set for NativeScript (more info at 'Package Managers' section of docs) and Nx (more info at 'Nx DevKit - Module' section of docs).

For an example, setting Yarn as your package manager, do the following:

ns package-manager set yarn

Now create a Nx workspace using the yarn command expression in the following section.

Create a new Nx workspace

# Using npm
npx create-nx-workspace@latest --cli=nx --preset=empty

# Using yarn
yarn create nx-workspace --cli=nx --preset=empty --packageManager=yarn

If you run into any issue with latest Nx workspace version you may want to try the last known stable version with the following:

npx create-nx-workspace@12.4 --cli=nx --preset=empty

Install NativeScript plugin

# Using npm
npm install --save-dev @nativescript/nx

# Using yarn
yarn add -D @nativescript/nx

Create an app

# Using npm
npx nx g @nativescript/nx:app <app-name> [...options]

# Using yarn
yarn nx g @nativescript/nx:app <app-name> [...options]

This will generate:

apps/nativescript-<app-name>

The NativeScript Nx plugin will prefix apps by default to help distinguish them against other apps in your workspace for clarity.

`--framework [angular|vanilla]`

You will be prompted to choose a framework when this flag is ommitted.

Use this option to explicitly choose a specific frontend framework integration app.

This setting will be saved with plugin settings the first time it's used to automatically choose this frontend framework integration for subsequent usages and with other generators without having to specify the flag again.

`--groupByName`

If you prefer you can also provide a flag to suffix instead:

npx nx g @nativescript/nx:app <app-name> --groupByName

This will generate:

apps/<app-name>-nativescript

Develop on simulators and devices

Android:

npx nx run <app-name>:android

iOS: (Mac only)

npx nx run <app-name>:ios

Run with a specific configuration

Android:

npx nx run <app-name>:android:prod

iOS: (Mac only)

npx nx run <app-name>:ios:prod

Run tests

Android:

npx nx run <app-name>:test:android

iOS: (Mac only)

npx nx run <app-name>:test:ios

You can generate coverage reports by using the flag with iOS or Android, for example:

npx nx run <app-name>:test:ios --coverage

You can also set this option in the config, for example:

"test": {
  "executor": "@nativescript/nx:test",
  "outputs": ["coverage/apps/nativescript-mobile"],
  "options": {
    "coverage": true // can set to always be on for both platforms
  },
  "configurations": {
    "android": {
      "coverage": false // or can override per platform if needed
    },
    "ios": {
      "coverage": true
    }
  }
}

Create a build

Instead of running the app on a simulator or device you can create a build for the purposes of distribution/release. Various release settings will be needed for iOS and Android which can be passed as additional command line arguments. See more in the NativeScript docs here. Any additional cli flags as stated in the docs can be passed on the end of the nx build command that follows.

Build with an environment configuration enabled (for example, with prod):

Android:

npx nx run <app-name>:build:prod --platform=android

You can pass additional NativeScript CLI options as flags on the end of you build command.

example of building AAB bundle for upload to Google Play:

npx nx run <app-name>:build:prod --platform=android \
  --aab \
  --key-store-path=<path-to-your-keystore> \
  --key-store-password=<your-key-store-password> \
  --key-store-alias=<your-alias-name> \
  --key-store-alias-password=<your-alias-password> \
  --copyTo=./dist/build.aab

iOS: (Mac only)

npx nx run <app-name>:build:prod --platform=ios

As mentioned, you can pass any additional NativeScript CLI options as flags on the end of your nx build command:

example of building IPA for upload to iOS TestFlight:

npx nx run <app-name>:build:prod --platform=ios \
  --provision <provisioning-profile-name> \
  --copy-to ./dist/build.ipa

Clean

It can be helpful to clean the app at times. This will clear out old dependencies plus iOS/Android platform files to give your app a nice reset.

npx nx run <app-name>:clean

Create NativeScript library

You can create a library of NativeScript components or plugins or whatever you'd like.

npx nx g @nativescript/nx:lib buttons

This will generate a nativescript-buttons library where you could build out an entire suite of button behaviors and styles for your NativeScript apps.

import { PrimaryButton } from '@myorg/nativescript-buttons';

The NativeScript Nx plugin will prefix libraries by default to help distinguish them against other apps and libraries in your workspace for clarity.

`--groupByName`

If you prefer you can also provide a flag to suffix instead:

npx nx g @nativescript/nx:lib buttons --groupByName

Which would generate a buttons-nativescript library.

import { PrimaryButton } from '@myorg/buttons-nativescript';

Using NativeScript plugins

NativeScript plugins can be used in Nx workspaces in one of the two following methods:

Installing NativeScript plugins at app-level

If the plugin is needed by one app only, and not others, you can install it for the specific app:

cd apps/<app-name>
npm install <plugin-name>

Installing NativeScript plugins at workspace-level

Alternatively, you can install the plugins at the workspace (root), so it is accesible to all your workspace apps:

npm install --save <plugin-name>

Known issues

If a plugin contains platforms folder with native includes, the plugin must be added to app package.json at moment. https://github.com/NativeScript/nx/issues/17#issuecomment-841680719
