grunt-closure-tools

Grunt plugin integrating Google Closure Library tools (Compiler, Builder, DepsWriter) for JavaScript minification, dependency calculation, and bundling. Version 1.0.0 (stable, last release 2019) targets Grunt 0.4.x. Supports Closure Compiler jar-based compilation, closurebuilder.py concatenation, and depswriter.py deps generation. Key differentiators: full Closure toolchain integration in Grunt, support for advanced compilation options, and file-level change detection (checkModified). Alternative to gulp-closure-compiler or webpack closure plugins.
