Babel v6 plugin that replaces all occurrences of __DEV__ with the evaluation of "production" !== process.env.NODE_ENV. Currently at version 2.0.1, with no recent updates. It simplifies stripping development-only code from production bundles. Unlike similar plugins, it evaluates the expression at build time, replacing __DEV__ with a boolean literal. Limited to Babel v6; unmaintained since 2018. Use @babel/plugin-transform-dotenv or custom plugins for modern Babel.
