ESLint Parsing error: Unexpected token - reactjs

Question

I'm making an app with React JS and I use eslint.
But I'm getting this error
6:22 error Parsing error: Unexpected token ..
for the next code :
import {AUTH_USER, UNAUTH_USER} from '../actions/types';
export default function (state = {}, action) {
switch (action.type){
case AUTH_USER:
return { ...state, authenticated: true };
case UNAUTH_USER:
return { ...state, authenticated: false };
default:
return state;
}
}
.eslintrc file is as follows :
{
"parserOptions": {
"ecmaVersion": 6,
"sourceType": "module",
"ecmaFeatures": {
"jsx": true,
"experimentalObjectRestSpread": true
}
},

}
}
If I try without "experimentalObjectRestSpread": true in the ecmaFeatures in the eslintrc file I get the error.
When I with it I don't see error but it still won't work. I get something like
Any advice?

The gulpfile.js is as follows :

Answer 1

You need to install:
npm install --save-dev babel-plugin-transform-object-rest-spread
then add :
"plugins": ["transform-object-rest-spread"]
together with your presets.
See redux doc at the bottom of the page.
Since the object spread syntax is still a Stage 2 proposal for ECMAScript
you’ll need to use a transpiler such as Babel to use it in production.
You can use your existing es2015 preset, install
babel-plugin-transform-object-rest-spread and add it individually to
the plugins array in your .babelrc.
{ "presets": ["es2015"], "plugins":
["transform-object-rest-spread"] }

Answer 2

It is even easier with just using "experimentalObjectRestSpread": true in the ecmaFeatures section.
