Nuclide: A unified IDE
Facebook seems to be pretty serious about React, and finally React Native.
Today they announced Nuclide: an open source IDE for React Native, web, and native mobile development, built on top of Atom to provide hackability, and backed by an active community.
Nuclide is the IDE for developing Hack-based web applications, providing auto-completion and inline error highlighting.
Nuclide has built-in support for React and React Native development, with Buck integration for rapid builds.
Nuclide is a set of packages implemented on top of Atom, and we are working closely with GitHub to contribute upstream to the core project.
