ts2dart is a TypeScript to Dart transpiler. It's mainly used to translate Angular 2 from TypeScript to Dart for its Dart user base.

• To install as Command Line Tool execute: npm i -g ts2dart
• Once installed you could run it doing: ts2dart inputFile.ts

• execute npm i to install the dependencies,
• the Dart SDK must be available to run end to end tests.

• gulp watch executes the unit tests in watch mode (use gulp test.unit for a single run),
• gulp test.e2e executes the e2e tests,
• gulp test.check-format checks the source code formatting using clang-format,
• gulp test runs unit tests, e2e tests and checks the source code formatting.

You can send pull requests via Github, or by creating a Phabricator diff on https://reviews.angular.io. Both are fine, though Phabricator has a nicer code review UI.

To create a Phabricator diff:

• create an account on https://reviews.angular.io
• install Arcanist
• run arc diff to upload a diff (= pull request). This will also run all tests.
• get it reviewed by entering a "Reviewer", e.g. "mprobst", "alexeagle", "viks", ...
