NativeScript Plugin for Nx

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

If updating from Nx <= 19 to >=20, see the migration guide for updates to your project.json and commands.

NativeScript Plugin for Nx

Getting started

Create a new Nx workspace

# Using npm
npx create-nx-workspace@latest

# Using yarn
yarn create-nx-workspace@latest

At the prompts, you can use:

✔ Where would you like to create your workspace? · {your-workspace-name}

? Which stack do you want to use? … 
None:          Configures a minimal structure without specific frameworks or technologies.
# Choose "None"

? Package-based monorepo, integrated monorepo, or standalone project?
Integrated Monorepo:        Nx creates a monorepo that contains multiple projects.
# Choose "Integrated"

? Do you want Nx Cloud to make your CI fast? 
# Choice is completely up to you

Init workspace

Initialize a TypeScript project -- This will ensure a tsconfig.base.json is created to begin building your workspace.

npx nx g @nx/js:init

Install NativeScript plugin

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

# Using yarn
yarn add -D @nativescript/nx

Note: If you get a Warning on peer dependencies you can ignore. For example:

npm WARN ERESOLVE overriding peer dependency
npm WARN While resolving: @swc-node/[email protected]
npm WARN Found: @swc/[email protected]
npm WARN node_modules/@swc/core
npm WARN   peer @swc/core@">= 1.3" from @swc-node/[email protected]

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

      "configurations": {}
    }
  }
}

Run with a specific configuration

Android:

npx nx debug <app-name> android -c=prod

iOS: (Mac only)

npx nx debug <app-name> ios -c=prod

Run tests

Android:

npx nx test <app-name> android

iOS: (Mac only)

npx nx test <app-name> ios

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

npx nx test <app-name> 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 build <app-name> android --c=prod

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 build <app-name> android --c=prod \
  --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 build <app-name> iod --c=prod

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 build <app-name> ios --c=prod \
  --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 clean <app-name>

Create NativeScript library

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

npx nx g @nativescript/nx:library 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:library 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
