@titanium-sdk/babel-preset-app

This is the default Babel preset used in Titanium app projects that have Webpack enabled.

ℹ️ Note: The Titanium CLI will automatically configure this preset based on your current build command. If you want to also include this preset in your third-party libraries you need to configure it yourself.

Included in this Preset

@babel/preset-env

preset-env automatically determines the transforms and polyfills to apply based on your current build target.

@babel/plugin-transform-runtime

transform-runtime avoids inlining helpers in every file. This is enabled for helpers only, since polyfills are handled by babel-preset-env.

babel-plugin-transform-titanium

babel-plugin-transform-titanium optimizes your Titanium SDK applications by inlining various static values. Once inlined, other babel plugins may perform additional optimizations to help strip away "dead code".

Options

env

All options from @babel/preset-env are supported under the env key.

titanium

All options from babel-plugin-transform-titanium are supported under the titanium key.

Default configuration

This preset will be automatically configured when used in Titanium app projects. The default options are:

• env

  • useBuiltIns: false: Disabled for now because the Titanium core runtime already bundles all neccessary polyfills. See TIMOB-27629 for a planned improvement of this option.
  • targets: Will be set depending on the platform you build for. On Android this is the V8 version Titanium was build for. On iOS this is either the configured <min-ios-ver> of your project, or the default minimum supported iOS version of the SDK you are building with.

• titanium

  • deploytype: The deployment type of the issued build command.
  • platform: The platform you are building for.
  • target: The deployment target you are building for.
  • Ti: Will be populated with values from the SDK you are building with.
