tns build

Description

Builds the project for Android <% if(isMacOS) { %>or iOS <% } %>and produces an application package that you can manually deploy on a device or native emulator. <% if(isMacOS) { %>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.

<% if(isHtml) { %>

NOTE: When passing --release CLI will disable HMR. <% } %>

Commands

Usage Synopsis
<% if((isConsole && isMacOS)

<% if((isConsole && isMacOS) || isHtml) { %>### 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.
