js-babel

library6.1.0jsnpmunverified

Consolidated Babel 6 dependencies for ES2015+ transpiling. Version 6.1.0 bundles core Babel presets (es2015, es2016, react) and plugins (class properties, destructuring, object rest spread, regenerator, runtime, etc.) as peer dependencies. Release cadence is low; focused on internal use by the author's modules. Key differentiator: single install for a curated set of Babel plugins, avoiding individual plugin management. However, it locks you into the author's chosen versions and presets, making upgrades to Babel or plugins dependent on this package's updates.
