babel-plugin-uglify

Babel plugin that integrates UglifyJS minification directly into the Babel pipeline without needing to generate and re-parse code. v1.0.2 is the latest stable release. This plugin works on the Mozilla AST (SpiderMonkey format) used internally by Babel, avoiding repeated code generation and parsing. It is intended for Babel 5.x only, as Babel 6+ uses different AST formats. No longer actively maintained; alternatives include babel-minify (babili) or terser-based plugins. Key differentiator: direct AST-level minification preserves source maps and avoids overhead of stringifying and re-parsing code.
