task-closure-tools

Core library for Google Closure Tools tasks, providing Compiler (JS minification using the Closure Compiler), Builder (concatenation and optional compilation), and DepsWriter (dependency graph generation for deps.js files). Current version 0.1.10, last updated June 2015 (infrequent updates). Primarily used as a base for Grunt plugins (grunt-closure-tools) and other build systems (Mantri). Differentiators: integrates directly with Google Closure Library ecosystem, supports Java-based Closure Compiler and Python-based DepsWriter, but node >=0.8.0 only, no modern ESM support.
