I recently set up webpack 3 and babel in my project. My entry file, index.js/bundle.js, is successfully building and running with ES7/8 features. However, I am facing an issue with imports causing an error "
Uncaught SyntaxError: Unexpected identifierpackage.json and a separate .babelrc file in the root directory of my app, but the import statement still throws an error. Is there something missing from my setup?
index.js (works)
// does not work
// import React from 'react'
// works
const object1 = {
a: 'somestring',
b: 42,
c: false
};
console.log(Object.values(object1));
webpack.config.js
const path = require('path')
module.exports = {
context: path.resolve(__dirname, 'app/assets/javascripts/source'),
entry: './index.js',
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'app/assets/javascripts/webpack')
},
