I'm trying to get my Browserify/Babelify/Gulp working in my project, but it won't take the spread operator.

I got this error from my gulpfile:

[SyntaxError: /Users/mboutin2/Desktop/Todo-tutorial/src/reducers/grocery-list-reducers.js: Unexpected token (16:8) while parsing file: /Users/mboutin2/Desktop/Todo-tutorial/src/reducers/grocery-list-reducers.js]

This is my gulpfile.js

var gulp = require('gulp');

var source = require('vinyl-source-stream');

var browserify = require('browserify');

var sourcemaps = require('gulp-sourcemaps');

var uglify = require('gulp-uglify');

var buffer = require('vinyl-buffer');

var babelify = require('babelify');



gulp.task('build', function () {

  return browserify({entries: './src/client/app.js', extensions: ['.js'], debug: true})

    .transform(babelify, {presets: ['es2015', 'react']})

    .bundle()

    .on('error', function (err) {

      console.error(err);

      this.emit('end');

    })

    .pipe(source('app.min.js'))

    .pipe(buffer())

    .pipe(sourcemaps.init({loadMaps: true}))

    .pipe(uglify())

    .pipe(sourcemaps.write('./'))

    .pipe(gulp.dest('./public/js'));

});



gulp.task('default', ['build']);

I tried to create a .babelrc file, but it do the same thing. And my script works when i delete the spread operator.

This is the file where the Unexpected token occurs (quite simple).

import utils from '../utils/consts';



const initialState = {

  itemList: [

    {name: 'Apple', type: 'Fruit'},

    {name: 'Beef', type: 'Meat'}

  ]

};



export function groceryList(state = initialState, action = {}) {



  switch(action.type) {



    case utils.ACTIONS.ITEM_SUBMIT:

      return {

        ...state,

        itemList: [

          ...state.itemList,

          {name: action.name, type: action.itemType}

        ]

      };



    default:

      return state;



  }

}

I don't know what doesn't work in this, i read some issues on Github and the setup page on Babel website, but i can't make it work correctly.

Can anyone show me how to handle this correctly? Thank you
