  -## The Angular Compatibility Compiler
  -
  -The Angular Compatibility (`ngcc`) compiler helps you compile third-party libraries with Ivy so that you can use them in your Ivy application.
  -Use a postinstall script in your `package.json` to always run `ngcc` when you install your `package.json` dependencies, so that all projects in the workspace are compiled with Ivy.

  -
  - Using a postinstall hook to run `ngcc` is just a temporary integration.
  - We expect `ngcc` to be seamlessly integrated into the Angular CLI build pipeline in the future before the full Ivy rollout.
  - Once that's implemented `ngcc` will not be visible to developers.
  -
  - Note that there are currently some build-time performance issues with `ngcc`. Please bear with us while we improve the tooling and build integration in the Angular CLI.
