来自grunt task_min doc:
Specifying UglifyJS options In this example,custom UglifyJS mangle,squeeze and codegen options are specified. The listed methods and their expected options are explained in the API section of the UglifyJS documentation: The mangle object is passed into the pro.ast_mangle method. The squeeze object is passed into the pro.ast_squeeze method. The codegen object is passed into the pro.gen_code method. // Project configuration. grunt.initConfig({ min: { dist: { src: ['dist/built.js'],dest: 'dist/built.min.js' } },uglify: { mangle: {toplevel: true},squeeze: {dead_code: false},codegen: {quote_keys: true} } });
