Installing Babel

The following are a few important npm packages.

Core Babel and access to Babel:

  • babel-core: the core compilation machinery and plugin infrastructure for Babel. You will rarely need to install this package, because other packages such as babel-cli have it as a dependency, meaning that it will be automatically installed when they are installed.

  • babel-cli: a command line interface to Babel. It includes the following commands:

  • babel-doctor detects common problems with your Babel installation.
