Hope you got your solution still answering here, it will help some people who needs to work react with grunt and babel

make sure first you have installed the followings:

Grunt plugin for Babel grunt-babel

npm install --save-dev babel-plugin-transform-es2015-modules-amd 

npm install babel-preset-env --save-dev 

npm install --save-dev babel-cli babel-preset-react

then add a grunt task/gruntfile as below :

module.exports = function (grunt) {
'use strict';
    babel: {
        options: {
            sourceMap: false,
            presets: ["env", "react"],
            plugins: ["transform-es2015-modules-amd"]
        dist: {
            files: [{
                expand: true,
                cwd: './src',
                src: ['*.js'],
                dest: './generated',
                ext: '.js'
  grunt.registerTask('default', ['babel']);


   "devDependencies": {
       "babel-cli": "^7.0.0-beta.3",
       "babel-core": "7.0.0-alpha.19",
       "babel-plugin-transform-es2015-modules-amd": "^7.0.0-alpha.19",
       "babel-preset-env": "^2.0.0-beta.2",
       "babel-preset-es2015": "7.0.0-alpha.19",
       "babel-preset-react": "^7.0.0-alpha.19",
       "grunt-babel": "^7.0.0",

Hope this helps.


babel -> @babel

Since Babel 7 the Babel team switched to scoped packages, so you now have to use @babel/core instead of babel-core.

Your dependencies will need to be modified like so:

babel-cli -> @babel/cli. Ex: babel- with @babel/.

package.json will be look like below:

"@babel/cli": "^7.1.2",
"@babel/core": "^7.1.2",
"@babel/preset-env": "^7.1.0",
"@babel/preset-react": "^7.0.0",
"grunt-babel": "^8.0.0",
