How to integrate uglify-es in grunt?

Question

I'm using gruntjs (which uses uglifyjs ) to build my Angularjs app. But uglifyjs still does not support es6, so in corresponding GitHub issue i found this . So now there is uglify-es, which seemingly supports es6. But I'm not sure how to integrate it with grunt. Now i have module "grunt-contrib-uglify" , which has a dependency uglifyjs , which is now used. How can i make grunt use uglify-es instead?

Answer 1

我通过安装支持es6的grunt-contrib-uglify uglify的和声分支实现了这个目的：

npm install git://github.com/gruntjs/grunt-contrib-uglify.git#harmony --save-dev

Answer 2

The ECMAScript version has finally been released. You can now get the same result with the official version (it's no longer needed to pick it from GitHub)

npm install grunt-contrib-uglify-es --save-dev
