tns build

Description

Builds the project for Android or iOS and produces an application package that you can manually deploy on a device or native emulator. You must specify the target platform for which you want to build your project.

When running this command the HMR (Hot Module Replacement) is not enabled by default. In case you want to enable HMR, you can pass --hmr flag.

NOTE: When passing --release CLI will disable HMR.

Commands

Usage Synopsis
General $ tns build <Platform>General

Arguments

<Platform> is the target mobile platform for which you want to build your project. You can set the following target platforms.

  • android - Build the project for Android and produces an APK that you can manually deploy on a device or in the native emulator.
  • ios - Build the project for iOS and produces an APP or IPA that you can manually deploy in the iOS Simulator or on a device.

Options

  • --justlaunch - If set, does not print the application output in the console.
  • --release -If set, produces a release build by running webpack in production mode and native build in release mode. Otherwise, produces a debug build.
  • --device - Specifies a connected device/emulator to start and run the app. <Device ID> is the index or Device Identifier of the target device as listed by the $ tns device <Platform> --available-devices command.
  • --hmr - Enables the hot module replacement (HMR) feature.
  • --env.* - Specifies additional flags that the bundler may process. Can be passed multiple times. Supported additional flags:
    • --env.aot - creates Ahead-Of-Time build (Angular only).
    • --env.snapshot- creates a V8 Snapshot decreasing the app start time (only for release builds for Android).
    • --env.compileSnapshot- compiles the static assets produced by --env.snapshot into .so files allowing the native build to split them per architecture. This will reduce the app size when using the --aab option.
    • --env.uglify - provides basic obfuscation and smaller app size.
    • --env.report - creates a Webpack report inside a report folder in the root folder.
    • --env.sourceMap - creates inline source maps.
    • --env.hiddenSourceMap - creates sources maps in the root folder (useful for Crashlytics usage with bundled app in release).
  • --aab - Specifies that the command will produce and deploy an Android App Bundle.
  • --force - If set, skips the application compatibility checks and forces npm i to ensure all dependencies are installed. Otherwise, the command will check the application compatibility with the current CLI version and could fail requiring tns migrate.
