library3.4.0jsnpmunverified

Babel preset for Facebook projects, version 3.4.0, stable. It includes transforms for modern JavaScript, Flow, and JSX (React), with options for auto-import, inline requires, module rewriting, and DEV stripping. Differentiators: official Facebook tooling for internal consistency, customizable via configure API, but tightly coupled to Facebook's ecosystem. Release cadence is infrequent.
