使用es6配置Grunt

Question

It is possible to write grunt config files in es6 like this?

module.exports = function (grunt) {
  var arr = [1,2,3];
  arr.forEach(val => {
    ...
  });
  ...
}

Answer 1

One possible way to do this painlessly is to use Babel's babel-register module like this:

Installation:

npm install babel-register --save-dev

.babelrc:

{
    presets: ["es2015"]
}

Gruntfile.js:

require('babel-register')

module.exports = require('./Gruntfile.es').default

Gruntfile.es

export default function(grunt) {
    grunt.initConfig({})
}

GruntJS is a javascript based application. It runs under the node/iojs process and adheres to the capabilities of that environment. If you use iojs or a node version that supports these features, then yes, its possible.
