mishoo/UglifyJS2 for cush
npm install cush-plugin-uglify-jsMinify assets using uglify-js.
By default, minification occurs in both development and production modes. This way, you can catch any rare bugs caused by minification, resulting in a better user experience.
The default settings for minification were carefully selected to avoid losing
information that's necessary for useful source maps. Transforms which are
unlikely to cause bugs are disabled in development mode for performance.
The uglify setting can be configured by your cush.config.js module.
Set it to false to disable minification, or provide [uglify options][opts]
to customize how modules are minified.
[opts]: https://github.com/mishoo/UglifyJS2#minify-options

// Inline single-use variables and functions, but make source maps less useful.
this.set('uglify', {
compress: {
inline: true,
reduce_vars: true,
reduce_funcs: true,
collapse_vars: true,
}
});
You can override any of these defaults.
